Abstract

Sex-based differences in autoimmune disease susceptibility have long been recognized, prompting investigations into how sex hormones influence immunity. Recent advances suggest that hormones may shape immune responses by altering cellular metabolism. In this issue of the JCI, Chowdhury et al. authenticates this model, showing that androgen receptor signaling modulates T helper 17 (Th17) cell metabolism, specifically glutaminolysis, reducing airway inflammation in males. This work provides insight into sex-specific regulation of immunity, highlighting the interplay between hormones, metabolism, and immune function. The findings raise intriguing questions about how hormonal fluctuations affect immunity and how sex-specific metabolic pathways might be leveraged for targeted therapies in autoimmune diseases.
