Whereas T cells from young subjects stimulated with cross-linked anti-CD3epsilon mAb OKT3 plus PMA or with the lectin PHA plus PMA demonstrated considerable increases in c-Fos protein expression , the expression of c-Fos but not c-Jun was markedly reduced in stimulated T cells from certain elderly subjects .
