Context-dependent androgen control of T cell immunity.

While androgen deprivation is widely used in urological oncology to restrain tumor growth and prevent T cell exhaustion, Lee et al. reveal a striking reversal in glioblastoma. In glioblastoma, androgen loss triggers microglial cytokines, activates the hypothalamic-pituitary-adrenal axis, and induces glucocorticoid-dependent T cell suppression, which accelerates tumor progression.
