Natural killer cell activation and inhibition

Web14 de abr. de 2024 · Abstract. The E3 ubiquitin ligase CBL-B is a master regulator of effector T cells through its downstream regulation of T-cell receptor and co-stimulatory stimulation, but it has also been shown to play a negative feedback role in NK cells. CBL-B depletion enhances the production of IFNγ and the cytotoxicity of activated NK cells.
