Taken together, these observations suggest that mitogenic activation , mediated primarily through the NF kappa B enhancer , is susceptible to CD8 -mediated inhibition , however, inhibition of Tat -mediated activation may rely upon a different pathway that is NFAT-1 dependent .
 ( protein: Tat, None) , ( DNA: NF kappa B enhancer, None) , ( protein: NFAT-1, None) , ( protein: NF kappa B, None) , ( protein: CD8, None)
