Abstract

Cholera toxin (CT) is a very effective adjuvant for mucosal vaccination. It binds to cells through its B subunit and induces intracellular increase of cAMP through the A subunit. We previously showed that CT induces maturation of human dendritic cells (DCs) and this may account for its adjuvant property. Here, we investigated the role of the A subunit on DCs maturation by using forskolin, a cAMP inducer. The results show that although cAMP does not stimulate full maturation of DCs it induces upregulation of the chemokine receptors CXCR4 and CCR7.
