(Calcium Signaling) :
In this study, the effect of antigen presenting cells (APC) , peptide concentration, and CD28 costimulation on calcium signaling, induced by antigen-specific T-cell activation, was studied by flow cytometry
Prilliman et al., J Immunol 2002
:
We find that both CD28 and B7-1/B7-2 are required for CD40 activated APC to cross-prime CTL, and that priming by CD40 activated APC was prevented by blockade of CD28
