Characterization of constitutive and strain-dependent subsets of CD45RA+ cells in the thymus.

abstract：:CD4 T cells are not thought to play a significant role in generating an effective primary CD8 T cell response to most viral infections. We have challenged this view by demonstrating that antigen-specific CD4 T cells can indeed suppress the proliferation of antigen-specific naive CD8 T cells in response to low doses of...
