A Tale of Three Systems: Toward a Neuroimmunoendocrine Model of Obesity.
The prevalence of obesity is on the rise. What was once considered a simple disease of energy imbalance is now recognized as a complex condition perpetuated by neuro- and immunopathologies. In this review, we summarize the current knowledge of the neuroimmunoendocrine mechanisms underlying obesity. We examine the pleiotropic effects of leptin action in addition to its established role in the modulation of appetite, and we discuss the neural circuitry mediating leptin action and how this is altered with obesity, both centrally (leptin resistance) and in adipose tissues (sympathetic neuropathy). Finally, we dissect the numerous causal and consequential roles of adipose tissue macrophages in obesity and highlight recent key studies demonstrating their direct role in organismal energy homeostasis.
期刊介绍:
The Annual Review of Cell and Developmental Biology, established in 1985, comprehensively addresses major advancements in cell and developmental biology. Encompassing the structure, function, and organization of cells, as well as the development and evolution of cells in relation to both single and multicellular organisms, the journal explores models and tools of molecular biology. As of the current volume, the journal has transitioned from gated to open access through Annual Reviews' Subscribe to Open program, making all articles published under a CC BY license.
