Ctl4 immunotherapy
CTLA-4 is a member of the immunoglobulin superfamily that is expressed by activated T cells and transmits an inhibitory signal to T cells. CTLA-4 is homologous to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA-4 binds CD80 and CD86 with greater affinity and avidity than CD28 thus enabling it to outcompete CD28 for its ligands. CTLA-4 transmits an inhibitory signal … WebBy 1999, Medarex had developed a therapeutic against CTL4, known originally by the dysarthric term ipilumimab, and eventually marketed as Yervoy. The dreaded skin cancer melanoma has long been a favorite proving ground for immunotherapy, because it appears to be especially provocative to the immune system. So Allison and Medarex went there first.
