Transfection studies of LTR reporter constructs indicated that mutation of the DSE sites abrogated the LTR -mediated synergy induced by Ctx and TNFalpha , whereas the synergy induced by Ctx and IL-1beta was unaffected, suggesting TNFalpha and IL-1beta cooperate differently with the cAMP /PKA activation pathway to induce HIV-1 expression in U1 cells .
