Cover Story Current Issue

Alterations in mitochondrial structure and function are commonly observed in adult-onset neurodegenerative diseases. In ALS, mitochondrial dysfunction impairs the efficiency of electron transport chain (ETC) activity and ATP production and leads to the accumulation of reactive oxygen and nitrogen species, abnormal handling of intracellular calcium and cytochrome C release and apoptosis. The extent to which these alterations in mitochondrial functionimpair cellular operations is unclear. Therapeutic intervention based on combating these mitochondrial abnormalities have displayed variable success in mouse models of ALS and humans, as reviewed in Vandoorne et al.

Leveraging GPCR signaling in thermogenic fat to counteract metabolic diseases
Background
Thermogenic brown and beige adipocytes are recognized for their unique capacity to consume extraordinary levels of metabolites and lipids from the blood to fuel heat-producing catabolic processes [[1], [2], [3], [4], [5], [6], [7]]. In humans, the functions of thermogenic adipocytes are associated with cardiometabolic protection and improved glycemic control [[8], [9], [10], [11], [12], [13]]. Consequently, engaging these macronutrient-consuming and energy-dissipating activities has gained attention as a promising therapeutic strategy for counteracting metabolic diseases, such as obesity and diabetes.
Scope of review
In this review, we highlight new advances in our understanding of the physiological role of G protein-coupled receptors (GPCRs) in controlling thermogenic adipocyte biology. We further extend our discussion to the opportunities and challenges posed by pharmacologically targeting different elements of GPCR signaling in these highly specialized fat cells.
Major conclusions
GPCRs represent appealing candidates through which to harness adipose thermogenesis. Yet safely and effectively targeting these druggable receptors on brown and beige adipocytes has thus far proven challenging. Therefore, continued interrogation across the GPCR landscape is necessary for future leaps within the field of thermogenic fat biology to unlock the therapeutic potential of adipocyte catabolism.
