Cell death-induced immunogenicity enhances chemoimmunotherapeutic response by converting immune-excluded into T-cell inflamed bladder tumors - Nature Communications

Chemoimmunotherapy recently failed to improve objective response for patients with advanced muscle-invasive bladder cancer (MIBC). Here using two murine models of immune-excluded MIBC, the authors show that resistance to chemoimmunotherapy can be overcome by blocking the COX-2/prostaglandin E2 axis, reinvigorating anti-tumor immune responses.

Anti-CTLA-4 antibodies drive myeloid activation and reprogram the tumor microenvironment through FcγR engagement and type I interferon signaling - Nature Cancer

Yofe et al. demonstrate that FcγR engagement early after anti-CTLA-4 blockade induces a rapid remodeling of innate immunity and activation of type I interferon signaling, which are crucial for successful anti-CTLA-4 therapy.

Blocking PD-L1–PD-1 improves senescence surveillance and ageing phenotypes - Nature

PD-L1 expression by senescent cells renders them resistant to clearance by CD8 T cells, suggesting PD-L1 as a target for mitigating the effects of ageing.
