Cytoplasmic protein kinase C (PKC) has been studied in phytohemagglutinin (PHA) activated peripheral blood mononuclear cells (PBMC) and macrophage depleted E+ cell culture.

Abstract
Cytoplasmic protein kinase C (PKC) has been studied in phytohemagglutinin (PHA) activated peripheral blood mononuclear cells (PBMC) and macrophage depleted E+ cell culture. Within 10' after contemporanous addition of PHA and anti HLA class I monoclonal antibody 01.65 (MoAb) PKC is depleted in both cell types. Enzyme activity recovers in the following hours however at 72 hours is at control values in E+ cultures while in PBMC cultures it is still depleted at 68% of the control. Anti HLA class I MoAb induced tritiated lymidine (3H-TdR) incorporation inhibition appears to be related to low levels of PKC activity.File in questo prodotto:
