Webb4 dec. 2007 · B7x was discovered in 2003, and in contrast to B7-H3, has consistently demonstrated a negative costimulatory mechanism via inhibition of CD4 + and CD8 + T cell proliferation, cell-cycle progression, IL-2 production, and rendering tumor cells refractory to apoptosis ( 8 – 10, 22 ). Webb30 juli 2024 · An immune checkpoint molecule, B7-H3, plays an inhibitory role in modulation of NK cells. To enhance NK cell functions, we generated NK-92MI cells carrying anti-B7-H3 CAR by lentiviral transduction. The expression of anti-B7-H3 CAR significantly enhanced the cytotoxicity of NK-92MI cells against B7-H3-positive tumor cells.

Webb31 maj 2005 · B7 ligands participate in immune responses by providing costimulatory or coinhibitory signals upon binding their receptor. Costimulatory signals are defined as those that act in conjunction with antigen-receptor signals, leading to productive cell activation, growth-factor production, cell expansion and survival (Figure 4a ).
