NR4A transcription factors control T cell dysfunction programs

March 13, 2019

T cell dysfunction – in the form of exhaustion, anergy, or tolerance – is known to limit the effector functions of T cells, but the molecular mechanisms that induce dysfunctional programs are not fully understood. Two recent studies, published back-to-back in Nature, investigated the mechanisms underlying T cell dysfunction, and through different strategies, both...

TAMs may be friends, not foes, in early-stage tumor T cell response

March 6, 2019

Knowing that immunotherapy that works in mice often fails in patients with solid tumors, and that mouse models mostly utilize tumor cell lines from advanced tumors, Singhal et al. decided to bypass murine studies entirely and instead analyzed the functions of macrophages and monocytes and their interactions with tumor-specific T cells within early-stage...
