Immunological synapse formation between T cells and target cells can affect the functional outcome of TCR ligation by a given MHC/peptide complex. Although synapse formation is usually induced by TCR signaling, it is not clear whether other factors can affect the efficiency of synapse formation. Here we tested whether cytokines could influence synapse formation between murine CTL and target cells. We found that IL-12 enhanced synapse formation, whereas TGF-β decreased synapse formation. The enhanced synapse formation induced by IL-12 appeared to be functional, as IL-12-treated cells could respond to weak peptides, including self-peptides, to which the T cells were normally unresponsive. These responses correlated with expression of functionally higher avidity LFA-1 on IL-12-treated CTL. These findings have implications for the function of IL-12 in T cell-mediated autoimmunity.
