Driven by increased caloric intake relative to expenditure, obesity is a major health concern placing economic and operational strain on healthcare and social care worldwide. Pharmacologically, one of the most effective avenues for the management of excess adiposity is the suppression of appetite. However, owing to the body's natural physiological ...

The liver plays a central role in regulating lipid and glucose metabolism, particularly in transitioning between energy storage and provision in fed and fasting states. Loss of metabolic flexibility, characterized by the impaired capacity to shift between different energy substrates, sets the stage for accumulation of hepatic triglyceride as lipid ...

Over the last decade, single-cell genomics has revealed remarkable heterogeneity and plasticity of cell types in the lungs and airways. The challenge now is to understand how these cell types interact in three-dimensional space to perform lung functions, facilitating airflow and gas exchange while simultaneously providing barrier function to avoid ...

The SLC12 family of genes encodes electroneutral Cl−-dependent cation transporters (i.e., Na-Cl, K-Cl, Na-K-2Cl cotransporters), which play significant roles in maintaining cell and body homeostasis. Recent resolution of their structures at the atomic level provides a new understanding how these transporters operate in health and disease and how th...

The importance of biological sex on disease etiology and outcomes has long been underinvestigated. While recent focus on characterizing sex differences in cardiac pathophysiology has led to improved inclusion of both sexes in scientific studies and clinical trials, much is still unknown about underlying differences in normal cardiac physiology. Thi...

Mitochondria are multifaceted organelles with several life-sustaining functions beyond energy transformation, including cell signaling, calcium homeostasis, hormone synthesis, programmed cell death (apoptosis), and others. A defining aspect of these dynamic organelles is their remarkable plasticity, which allows them to sense, respond, and adapt to...

The Frank-Starling law and Anrep effect describe two intrinsic mechanisms that regulate contraction force in the heart. Based on recent advancements and the historical literature, we propose new perspectives and address several critical issues in this review. (a) The Frank-Starling mechanism and Anrep effect are dynamically linked and act synergist...

Sex and gender have emerged as critical considerations relevant to chronic obstructive pulmonary disease (COPD). Sex differences in lung development and physiologic response to hormones and environmental exposures influence COPD susceptibility, progression, severity, morbidity, and mortality. Gender has been poorly measured in the context of COPD, ...

Lung inflammation, infection, and injury can lead to critical illness and death. The current means to pharmacologically treat excessive uncontrolled lung inflammation needs improvement because many treatments are or will become immunosuppressive. The inflammatory response evolved to protect the host from microbes, injury, and environmental insults....

Calcium ions mediate the volume homeostasis of human red blood cells (RBCs) in the circulation. The mechanism by which calcium ions affect RBC hydration states always follows the same sequence. Deformation of RBCs traversing capillaries briefly activates mechanosensitive PIEZO1 channels, allowing Ca2+ influx down its steep inward gradient transient...
