CD28 (cluster of differentiation 28) is a protein expressed on T cells that provides essential co-stimulatory signals required for T cell activation and survival. When T cells are stimulated through CD28 in conjunction with the T-cell receptor (TCR), it enhances the production of various interleukins, particularly IL-6.
