Secretion of exosomes by fully activated Cytotoxic T cells is mediated by which cytokine?

Secretion of exosomes by fully activated Cytotoxic T cells is mediated by which cytokine? Correct Answer IL-12

Fully activated Cytotoxic T cells can secrete exosomes with the help of cytokine IL-12. This secretion results in strong affinity cytotoxic T cell peptides. Exosomes secreted by these fully activated cells strengthens the weak cytotoxic T cells that have low affinity peptides. Exosomes also enhance the activation of these weak cells. IL-12 plays a very important role as it acts as a mediator in order to carry out this mechanism. It also induces self-reactivity within cytotoxic T cells.
