A Conversation with Leonard and Leonore Herzenberg
Vol. 76 (2014), pp. 1–20More LessLeonard and Leonore Herzenberg have left an indelible mark on the fields of immunology and cell biology, both in research and clinical aspects. They are perhaps best known for developing the technologies of fluorescence flow cytometry and hybridomas. Over six decades, they made a number of important and fundamental discoveries in lymphocyte biology by applying these technologies. During this era, they immersed themselves in the sociopolitical environment, interjecting scientific rationale into public discourse about McCarthyism, nuclear fallout, war, genetics, and other politically charged topics. Their unique philosophy has shaped their lives, their science, and ultimately the scientific community. In this Conversation, we explore some of these driving forces and the impact on the laboratory.

Direct Reprogramming of Fibroblasts into Myocytes to Reverse Fibrosis
Naoto Muraoka, and Masaki IedaVol. 76 (2014), pp. 21–37More LessHeart disease is a major cause of morbidity and mortality worldwide. The low regenerative capacity of adult human hearts has thus far limited the available therapeutic approaches for heart failure. Therefore, new therapies that can regenerate damaged myocardium and improve heart function are urgently needed. Although cell transplantation–based therapies may hold great potential, direct reprogramming of endogenous cardiac fibroblasts, which represent more than half of the cells in the heart, into functional cardiomyocytes in situ may be an alternative strategy by which to regenerate the heart. We and others demonstrated that functional cardiomyocytes can be directly generated from fibroblasts by using several combinations of cardiac-enriched factors in mouse and human. In vivo gene delivery of cardiac reprogramming factors generates new cardiac muscle and improved heart function after myocardial infarction in mouse. This article reviews recent progress in cardiac reprogramming research and discusses the perspectives and challenges of this new technology for future regenerative therapy.

Hypoxia-Inducible Factor 1 and Cardiovascular Disease
Vol. 76 (2014), pp. 39–56More LessCardiac function is required for blood circulation and systemic oxygen delivery. However, the heart has intrinsic oxygen demands that must be met to maintain effective contractility. Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that functions as a master regulator of oxygen homeostasis in all metazoan species. HIF-1 controls oxygen delivery, by regulating angiogenesis and vascular remodeling, and oxygen utilization, by regulating glucose metabolism and redox homeostasis. Analysis of animal models suggests that by activation of these homeostatic mechanisms, HIF-1 plays a critical protective role in the pathophysiology of ischemic heart disease and pressure-overload heart failure.

Inflammasomes and Metabolic Disease
Vol. 76 (2014), pp. 57–78More LessInnate immune response pathways and metabolic pathways are evolutionarily conserved throughout species and are fundamental to survival. As such, the regulation of whole-body and cellular metabolism is intimately integrated with immune responses. However, the introduction of new variables to this delicate evolutionarily conserved physiological interaction can lead to deleterious consequences for organisms as a result of inappropriate immune responses. In recent decades, the prevalence and incidence of metabolic diseases associated with obesity have dramatically increased worldwide. As a recently acquired human characteristic, obesity has exposed the critical role of innate immune pathways in multiple metabolic pathophysiological processes. Here, we review recent evidence that highlights inflammasomes as critical sensors of metabolic perturbations in multiple tissues and their role in the progression of highly prevalent metabolic diseases.

Redox-Dependent Anti-Inflammatory Signaling Actions of Unsaturated Fatty Acids
Vol. 76 (2014), pp. 79–105More LessUnsaturated fatty acids are metabolized to reactive products that can act as pro- or anti-inflammatory signaling mediators. Electrophilic fatty acid species, including nitro- and oxo-containing fatty acids, display salutary anti-inflammatory and metabolic actions. Electrophilicity can be conferred by both enzymatic and oxidative reactions, via the homolytic addition of nitrogen dioxide to a double bond or via the formation of α,β-unsaturated carbonyl and epoxide substituents. The endogenous formation of electrophilic fatty acids is significant and influenced by diet, metabolic, and inflammatory reactions. Transcriptional regulatory proteins and enzymes can sense the redox status of the surrounding environment upon electrophilic fatty acid adduction of functionally significant, nucleophilic cysteines. Through this covalent and often reversible posttranslational modification, gene expression and metabolic responses are induced. At low concentrations, the pleiotropic signaling actions that are regulated by these protein targets suggest that some classes of electrophilic lipids may be useful for treating metabolic and inflammatory diseases.

Cardiac Sarcoplasmic Reticulum Calcium Leak: Basis and Roles in Cardiac Dysfunction
Vol. 76 (2014), pp. 107–127More LessSynchronized SR calcium (Ca) release is critical to normal cardiac myocyte excitation-contraction coupling, and ideally this release shuts off completely between heartbeats. However, other SR Ca release events are referred to collectively as SR Ca leak (which includes Ca sparks and waves as well as smaller events not detectable as Ca sparks). Much, but not all, of the SR Ca leak occurs via ryanodine receptors and can be exacerbated in pathological states such as heart failure. The extent of SR Ca leak is important because it can (a) reduce SR Ca available for release, causing systolic dysfunction; (b) elevate diastolic [Ca]i, contributing to diastolic dysfunction; (c) cause triggered arrhythmias; and (d) be energetically costly because of extra ATP used to repump Ca. This review addresses quantitative aspects and manifestations of SR Ca leak and its measurement, and how leak is modulated by Ca, associated proteins, and posttranslational modifications in health and disease.

Control of Life-or-Death Decisions by RIP1 Kinase
Vol. 76 (2014), pp. 129–150More LessRIP1 kinase, a multifunctional protein that contains an N-terminal Ser/Thr kinase and a C-terminal death domain, has emerged as a key regulatory molecule involved in regulating both cell death and cell survival. When the proinflammatory cytokine TNFα stimulates its receptor, TNFR1, RIP1 regulates whether the cell lives by activating NF-κB or dies by apoptosis or necroptosis, two distinct pathways of programmed cell death that may be activated to eliminate unwanted cells. The kinase domain of RIP1 is involved in regulating necroptosis, and the death domain regulates RIP1 recruitment to the intracellular domain of TNFR1. The intermediate domain of RIP1 activates NF-κB and also interacts with RIP3 kinase, a downstream mediator of RIP1 in the execution of necroptosis. This review focuses on the functional roles of RIP1 in regulating multiple cellular mechanisms, the dynamic regulation of RIP1, and the physiological and pathological roles of RIP1 kinase in human health and disease.

Mammalian Pheromones
Vol. 76 (2014), pp. 151–175More LessMammalian pheromones control a myriad of innate social behaviors and acutely regulate hormone levels. Responses to pheromones are highly robust, reproducible, and stereotyped and likely involve developmentally predetermined neural circuits. Here, I review several facets of pheromone transduction in mammals, including (a) chemosensory receptors and signaling components of the main olfactory epithelium and vomeronasal organ involved in pheromone detection; (b) pheromone-activated neural circuits subject to sex-specific and state-dependent modulation; and (c) the striking chemical diversity of mammalian pheromones, which range from small, volatile molecules and sulfated steroids to large families of proteins. Finally, I review (d) molecular mechanisms underlying various behavioral and endocrine responses, including modulation of puberty and estrous; control of reproduction, aggression, suckling, and parental behaviors; individual recognition; and distinguishing of own species from predators, competitors, and prey. Deconstruction of pheromone transduction mechanisms provides a critical foundation for understanding how odor response pathways generate instinctive behaviors.

Emerging Roles of Orphan Nuclear Receptors in Cancer
Sung Hee Baek, and Keun Il KimVol. 76 (2014), pp. 177–195More LessA growing body of evidence suggests that a subset of orphan nuclear receptors are amplified and prognostic for some human cancers. However, the specific roles of these orphan nuclear receptors in tumor progression and their utility as drug targets are not fully understood. In this review, we summarize recent progress in elucidating the direct and indirect involvement of orphan nuclear receptors in cancer as well as their therapeutic potential in a variety of human cancers. Furthermore, we contrast the role of orphan nuclear receptors in cancer with the known roles of estrogen receptor and androgen receptor in hormone-dependent cancers.

Feed Your Head: Neurodevelopmental Control of Feeding and Metabolism
Vol. 76 (2014), pp. 197–223More LessDuring critical periods of development early in life, excessive or scarce nutritional environments can disrupt the development of central feeding and metabolic neural circuitry, leading to obesity and metabolic disorders in adulthood. A better understanding of the genetic networks that control the development of feeding and metabolic neural circuits, along with knowledge of how and where dietary signals disrupt this process, can serve as the basis for future therapies aimed at reversing the public health crisis that is now building as a result of the global obesity epidemic. This review of animal and human studies highlights recent insights into the molecular mechanisms that regulate the development of central feeding circuitries, the mechanisms by which gestational and early postnatal nutritional status affects this process, and approaches aimed at counteracting the deleterious effects of early over- and underfeeding.

A New Era in Brown Adipose Tissue Biology: Molecular Control of Brown Fat Development and Energy Homeostasis
Vol. 76 (2014), pp. 225–249More LessBrown adipose tissue (BAT) is specialized to dissipate chemical energy in the form of heat as a defense against cold and excessive feeding. Interest in the field of BAT biology has exploded in the past few years because of the therapeutic potential of BAT to counteract obesity and obesity-related diseases, including insulin resistance. Much progress has been made, particularly in the areas of BAT physiology in adult humans, developmental lineages of brown adipose cell fate, and hormonal control of BAT thermogenesis. As we enter into a new era of brown fat biology, the next challenge will be to develop strategies for activating BAT thermogenesis in adult humans to increase whole-body energy expenditure. This article reviews the recent major advances in this field and discusses emerging questions.

The Intestinal Absorption of Folates
Vol. 76 (2014), pp. 251–274More LessThe properties of intestinal folate absorption were documented decades ago. However, it was only recently that the proton-coupled folate transporter (PCFT) was identified and its critical role in folate transport across the apical brush-border membrane of the proximal small intestine established by the loss-of-function mutations identified in the PCFT gene in subjects with hereditary folate malabsorption and, more recently, by the Pcft-null mouse. This article reviews the current understanding of the properties of PCFT-mediated transport and how they differ from those of the reduced folate carrier. Other processes that contribute to the transport of folates across the enterocyte, along with the contribution of the enterohepatic circulation, are considered. Important unresolved issues are addressed, including the mechanism of intestinal folate absorption in the absence of PCFT and regulation of PCFT gene expression. The impact of a variety of ions, organic molecules, and drugs on PCFT-mediated folate transport is described.

Trafficking of Epidermal Growth Factor Receptor Ligands in Polarized Epithelial Cells
Vol. 76 (2014), pp. 275–300More LessA largely unilamellar epithelial layer lines body cavities and organ ducts such as the digestive tract and kidney tubules. This polarized epithelium is composed of biochemically and functionally separate apical and basolateral surfaces. The epidermal growth factor receptor (EGFR) signaling pathway is a critical regulator of epithelial homeostasis and is perturbed in a number of epithelial disorders. It is underappreciated that in vivo EGFR signaling is most often initiated by cell-surface delivery and processing of one of seven transmembrane ligands, resulting in release of the soluble form that binds EGFR. In polarized epithelial cells, EGFR is restricted largely to the basolateral surface, and apical or basolateral ligand delivery therefore has important biological consequences. In vitro approaches have been used to study the biosynthesis, cell-surface delivery, proteolytic processing, and release of soluble EGFR ligands in polarized epithelial cells. We review these results, discuss their relevance to normal physiology, and demonstrate the pathophysiological consequences of aberrant trafficking. These studies have uncovered a rich diversity of apico-basolateral trafficking mechanisms among the EGFR ligands, provided insights into the pathogenesis of an inherited magnesium-wasting disorder of the kidney (isolated renal hypomagnesemia), and identified a new mode of EGFR ligand signaling via exosomes.

Exocytosis and Endocytosis: Modes, Functions, and Coupling Mechanisms*
Vol. 76 (2014), pp. 301–331More LessVesicle exocytosis releases content to mediate many biological events, including synaptic transmission essential for brain functions. Following exocytosis, endocytosis is initiated to retrieve exocytosed vesicles within seconds to minutes. Decades of studies in secretory cells reveal three exocytosis modes coupled to three endocytosis modes: (a) full-collapse fusion, in which vesicles collapse into the plasma membrane, followed by classical endocytosis involving membrane invagination and vesicle reformation; (b) kiss-and-run, in which the fusion pore opens and closes; and (c) compound exocytosis, which involves exocytosis of giant vesicles formed via vesicle-vesicle fusion, followed by bulk endocytosis that retrieves giant vesicles. Here we review these exo- and endocytosis modes and their roles in regulating quantal size and synaptic strength, generating synaptic plasticity, maintaining exocytosis, and clearing release sites for vesicle replenishment. Furthermore, we highlight recent progress in understanding how vesicle endocytosis is initiated and is thus coupled to exocytosis. The emerging model is that calcium influx via voltage-dependent calcium channels at the calcium microdomain triggers endocytosis and controls endocytosis rate; calmodulin and synaptotagmin are the calcium sensors; and the exocytosis machinery, including SNARE proteins (synaptobrevin, SNAP25, and syntaxin), is needed to coinitiate endocytosis, likely to control the amount of endocytosis.

Molecular Mechanisms for Synchronous, Asynchronous, and Spontaneous Neurotransmitter Release
Vol. 76 (2014), pp. 333–363More LessMost neuronal communication relies upon the synchronous release of neurotransmitters, which occurs through synaptic vesicle exocytosis triggered by action potential invasion of a presynaptic bouton. However, neurotransmitters are also released asynchronously with a longer, variable delay following an action potential or spontaneously in the absence of action potentials. A compelling body of research has identified roles and mechanisms for synchronous release, but asynchronous release and spontaneous release are less well understood. In this review, we analyze how the mechanisms of the three release modes overlap and what molecular pathways underlie asynchronous and spontaneous release. We conclude that the modes of release have key fusion processes in common but may differ in the source of and necessity for Ca2+ to trigger release and in the identity of the Ca2+ sensor for release.

Plasticity of Dendritic Spines: Subcompartmentalization of Signaling
Vol. 76 (2014), pp. 365–385More LessThe ability to induce and study neuronal plasticity in single dendritic spines has greatly advanced our understanding of the signaling mechanisms that mediate long-term potentiation. It is now clear that in addition to compartmentalization by the individual spine, subcompartmentalization of biochemical signals occurs at specialized microdomains within the spine. The spatiotemporal coordination of these complex cascades allows for the concomitant remodeling of the postsynaptic density and actin spinoskeleton and for the regulation of membrane traffic to express functional and structural plasticity. Here, we highlight recent findings in the signaling cascades at spine microdomains as well as the challenges and approaches to studying plasticity at the spine level.

Advances in Understanding the Urine-Concentrating Mechanism
Vol. 76 (2014), pp. 387–409More LessThe renal medulla produces concentrated urine through the generation of an osmotic gradient that progressively increases from the cortico-medullary boundary to the inner medullary tip. In the outer medulla, the osmolality gradient arises principally from vigorous active transport of NaCl, without accompanying water, from the thick ascending limbs of short- and long-looped nephrons. In the inner medulla, the source of the osmotic gradient has not been identified. Recently, there have been important advances in our understanding of key components of the urine-concentrating mechanism, including (a) better understanding of the regulation of water, urea, and sodium transport proteins; (b) better resolution of the anatomical relationships in the medulla; and (c) improvements in mathematical modeling of the urine-concentrating mechanism. Continued experimental investigation of signaling pathways regulating transepithelial transport, both in normal animals and in knockout mice, and incorporation of the resulting information into mathematical simulations may help to more fully elucidate the mechanism for concentrating urine in the inner medulla.

Mechanisms and Regulation of Renal Magnesium Transport
Vol. 76 (2014), pp. 411–430More LessMagnesium's most important role is in the release of chemical energy. Although most magnesium is stored outside of the extracellular fluid compartment, the regulated value is blood magnesium concentration. Cellular magnesium and bone magnesium do not play a major role in the defense of blood magnesium concentration; the major role is played by the kidney, where the renal tubule matches the urinary magnesium excretion and the net entry of magnesium into the extracellular fluid. In the kidney, magnesium is reabsorbed in the proximal tubule, the thick ascending limb of the loop of Henle, and the distal convoluted tubule. Magnesium absorption is mainly paracellular in the proximal tubule and in the thick ascending limb of the loop of Henle, whereas it is transcellular in the distal convoluted tubule. Several hormones and extracellular magnesium itself alter the distal tubular handling of magnesium, but the hormone(s) regulating extracellular magnesium concentration remains unknown.

Live Imaging of the Lung
Vol. 76 (2014), pp. 431–445More LessLive lung imaging has spanned the discovery of capillaries in the frog lung by Malpighi to the current use of single and multiphoton imaging of intravital and isolated perfused lung preparations incorporating fluorescent molecular probes and transgenic reporter mice. Along the way, much has been learned about the unique microcirculation of the lung, including immune cell migration and the mechanisms by which cells at the alveolar-capillary interface communicate with each other. In this review, we highlight live lung imaging techniques as applied to the role of mitochondria in lung immunity, mechanisms of signal transduction in lung compartments, studies on the composition of alveolar wall liquid, and neutrophil and platelet trafficking in the lung under homeostatic and inflammatory conditions. New applications of live lung imaging and the limitations of current techniques are discussed.

Nanoparticles, Lung Injury, and the Role of Oxidant Stress
Vol. 76 (2014), pp. 447–465More LessThe emergence of engineered nanoscale materials has provided significant advancements in electronic, biomedical, and material science applications. Both engineered nanoparticles and nanoparticles derived from combustion or incidental processes exhibit a range of physical and chemical properties that induce inflammation and oxidative stress in biological systems. Oxidative stress reflects the imbalance between the generation of reactive oxygen species and the biochemical mechanisms to detoxify and repair the damage resulting from reactive intermediates. This review examines current research on incidental and engineered nanoparticles in terms of their health effects on lungs and the mechanisms by which oxidative stress via physicochemical characteristics influences toxicity or biocompatibility. Although oxidative stress has generally been thought of as an adverse biological outcome, this review also briefly discusses some of the potential emerging technologies to use nanoparticle-induced oxidative stress to treat disease in a site-specific fashion.

Resolution of Acute Inflammation in the Lung
Vol. 76 (2014), pp. 467–492More LessAcute inflammation in the lung is essential to health. So too is its resolution. In response to invading microbes, noxious stimuli, or tissue injury, an acute inflammatory response is mounted to protect the host. To limit inflammation and prevent collateral injury of healthy, uninvolved tissue, the lung orchestrates the formation of specialized proresolving mediators, specifically lipoxins, resolvins, protectins, and maresins. These immunoresolvents are agonists for resolution that interact with specific receptors on leukocytes and structural cells to blunt further inflammation and promote catabasis. This process appears to be defective in several common lung diseases that are characterized by excess or chronic inflammation. Here, we review the molecular and cellular effectors of resolution of acute inflammation in the lung.

Tobacco Smoke–Induced Lung Fibrosis and Emphysema
Vol. 76 (2014), pp. 493–513More LessDespite public health campaigns discouraging smoking, 1,000 American children every day become smokers, ensuring that tobacco-related health complications will be with us for decades to come. Smoking is the greatest risk factor for both chronic obstructive lung disease and interstitial lung disease. The facts that not every smoker develops chronic lung disease and that lung pathology differs markedly among smokers indicate that individual susceptibility must be a central determinant of lung injury responses to cigarette smoke. Comparative examination of pathogenic mechanisms of smoke-induced lung disease can shed light on the homeostatic pathways critical to maintaining lung health. In this review, we explore common and divergent biological forces tilting the lung homeostatic balance away from health and toward emphysema or pulmonary fibrosis. We emphasize recent insights that highlight the greatest contrasts or similarities in the pathogenesis of these two chronic lung disease phenotypes.

The Central Nervous System Sites Mediating the Orexigenic Actions of Ghrelin
B.L. Mason, Q. Wang, and J.M. ZigmanVol. 76 (2014), pp. 519–533More LessThe peptide hormone ghrelin is important for both homeostatic and hedonic eating behaviors, and its orexigenic actions occur mainly via binding to the only known ghrelin receptor, the growth hormone secretagogue receptor (GHSR). GHSRs are located in several distinct regions of the central nervous system. This review discusses those central nervous system sites that have been found to play critical roles in the orexigenic actions of ghrelin, including hypothalamic nuclei, the hippocampus, the amygdala, the caudal brain stem, and midbrain dopaminergic neurons. Hopefully, this review can be used as a stepping stone for the reader wanting to gain a clearer understanding of the central nervous system sites of direct ghrelin action on feeding behavior, and as inspiration for future studies to provide an even-more-detailed map of the neurocircuitry controlling eating and body weight.

Glucagon-Like Peptide-1: Glucose Homeostasis and Beyond
Vol. 76 (2014), pp. 535–559More LessGlucagon-like peptide-1 (GLP-1), an incretin hormone secreted primarily from the intestinal L-cells in response to meals, modulates nutrient homeostasis via actions exerted in multiple tissues and cell types. GLP-1 and its analogs, as well as compounds that inhibit endogenous GLP-1 breakdown, have become an effective therapeutic strategy for many subjects with type 2 diabetes. Here we review the discovery of GLP-1; its synthesis, secretion, and elimination from the circulation; and its multiple pancreatic and extrapancreatic effects. Finally, we review current options for GLP-1-based diabetes therapy, including GLP-1 receptor agonism and inhibition of GLP-1 breakdown, as well as the benefits and drawbacks of different modes of therapy and the potential for new therapeutic avenues.

Physiology and Pharmacology of the Enteroendocrine Hormone Glucagon-Like Peptide-2
Vol. 76 (2014), pp. 561–583More LessGlucagon-like peptide-2 (GLP-2) is a 33-amino-acid proglucagon-derived peptide secreted from enteroendocrine L cells. GLP-2 circulates at low basal levels in the fasting period, and plasma levels rise rapidly after food ingestion. Renal clearance and enzymatic inactivation control the elimination of bioactive GLP-2. GLP-2 increases mesenteric blood flow and activates proabsorptive pathways in the gut, facilitating nutrient absorption. GLP-2 also enhances gut barrier function and induces proliferative and cytoprotective pathways in the small bowel. The actions of GLP-2 are transduced via a single G protein–coupled receptor (GLP-2R), expressed predominantly within the gastrointestinal tract. Disruption of GLP-2R signaling increases susceptibility to gut injury and impairs the adaptive mucosal response to refeeding. Sustained augmentation of GLP-2R signaling reduces the requirement for parenteral nutrition in human subjects with short-bowel syndrome. Hence GLP-2 integrates nutrient-derived signals to optimize mucosal integrity and energy absorption.

The Role of Gut Hormone Peptide YY in Energy and Glucose Homeostasis: Twelve Years On
Vol. 76 (2014), pp. 585–608More LessAlthough the role of peptide YY (PYY) as a regulator of energy homeostasis was first highlighted only in 2002, our understanding of the physiological role of PYY has since rapidly advanced. In recent years, insights from mechanistic studies in patients undergoing bariatric surgery, from pancreatic islet research, from functional neuroimaging studies, and from exercise research have greatly added to the field, and these areas provide the focus of discussion for this narrative review. We critically discuss recent findings relating to the role of PYY in mediating the beneficial effects of bariatric surgery, the role of PYY in glucose homeostasis, the role of hepatoportal PYY in mediating its central physiological effects, the specific modulation of brain regions by PYY, and the exercise-induced PYY response.
