Sendai virus-specific T cell clones II. Induction of interferon production by Sendai virus-specific T helper cell clones.

abstract：:T cell receptor (TCR) down-regulation is a consequence of specific receptor engagement and plays an important role in modulating the T cell response. We have investigated the role of protein kinase C (PKC) and protein tyrosine kinases (PTK) in the induction of TCR down-regulation. We report that the mutation of S126 i...
