A depletion experiment is only as good as the depletion you can prove. Injecting a functional-grade antibody and assuming the population is gone is the most common failure mode in in vivo immunology.

A natural killer cell decides by subtraction. It carries no rearranged antigen receptor and no memory of what it has seen. It presses a panel of germline-encoded receptors against a target and integr

Explore the complexities of Interleukin-10 (IL-10) signaling and regulation, a crucial aspect in immune response modulation and its dual roles in cancer development and therapy. Key Takeaways:

An antibody's variable domains decide what it binds. Its Fc decides what happens next — and that is not a detail of formulation, it is half the mechanism. Which Fcγ receptor the constant region engag

Transplant rejection is the fastest, most violent adaptive immune response a body can mount — and it is a response to a molecule rather than to a pathogen. Somewhere between one and ten per cent of a

CD4+ T cells are central to the immune system, functioning as coordinators of immune responses and regulators of immune tolerance. These cells are divided into two primary subtypes: Helpe
