PD-1 engagement enhances anti-tumor vaccine in mice

“B7-DC-Ig Enhances Vaccine Effect by a Novel Mechanism Dependent on PD-1 Expression level on T Cell Subsets”

M. Mkrtichyan,  S.N. Khleif, et al. (2012) J Immunol 189(5): 2338-2347.

 

Engagement of CD279(PD-1) by recombinant CD273 (B7-DC)-muIg enhances effect of anti-tumor vaccine in mice.

Two proposed mechanisms by which this recombinant protein may augment anti tumor vaccine effect: 1) It  inhibits proliferation of PD-1high CD4+ T cells, thereby reducing the number of T reg cells within the tumor.  2) It decreases the number of exhausted CD8+ T cells which leads to a better tumor specific cytotoxic response.
