靶點詳情

  • 功能:
    Inhibitory receptor acting as a major negative regulator of T-cell responses. The affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28.
  • 基因功能參考文獻:

Combining PD-L1 checkpoint inhibition with whole tumor cell/anti-CTLA-4 vaccination enhanced tumor cell killing, cured mice with established tumors, and induced long-term immune memory (6 months). PMID: 29377881
    2. the investigation of RANK and RANKL as possible novel immunotherapy targets in cancer is a rational approach. Here we have defined the mechanism of action of RANKL-RANK blockade in combination with anti-CTLA4, and provide insight into the combination efficacy observed in the case reports. PMID: 28634284
    3. reveal a novel CTLA-4-mediated pathway to attenuate cytotoxic T-lymphocytes and indicate the importance of post-transcriptional mechanisms in the regulation of anti-tumor immune responses PMID: 28644433

    6. These results suggest that CD44(+)CD117(+) T cells are stem cells and a specific T-cell phenotype that initially develops in the thymus, but they do not progress through DN3 and DN4 stages, lack a DP stage, and potently suppress T-cell proliferation and modulate the CTLA-4 pathway.

    26. The study concludes that although the presence of CTLA4 plays a critical role in controlling homeostasis of T cells, its quantitative variation may impose diverse or even opposing effects on distinct lineages of T cells, an optimal sum of which is necessary for preservation of T cell immunity while suppressing tissue damage.
