Problem: Interestingly , we demonstrated that stimulation by tumor cells was required to trigger the inhibitory effect of p58 on the lytic activity of antigen - specific CTLs and that stimulation of the inhibitory function of p58 by tumor cells correlated with an inhibition of nuclear factor - kappaB activation in p58 + tumor - specific CTLS .
Solution:
nuclear factor
