Levels of mRNA for LFA-1 (a), CD28 (b) and CD69 (c) in resting lymphocytes (LA), PMA-stimulated lymphocytes (LPMA), PMA-stimulated lymphocytes co-cultured with fibroblasts (LPMA+FA) and PMA-stimulated lymphocytes co-cultured with fibroblasts in the presence of a semipermeable membrane (LPMA+FA ins.). In the upper panels, modifications in the appearance of a 337-bp (LFA-1), a 304-bp (CD28) and a 451-bp (CD69) band are compared with that of a β-actin. In the lower panels, the densitometric analysis is shown. Data are from one experiment representative of three.
