Monoclonal anti HLA class I antibodies inhibit the proliferative response of PHA-stimulated T lymphocytes. We studied the effects of MAb 01.65 anti-HLA class I on c-fos, c-myc and IL-2R mRNA expression. We found that MAb treatment does not modify either c-fos mRNA levels observed after 10 minutes to 3 hrs or the early c-myc mRNA expression revealed after 1 to 6 hrs, but decreases the intensity of autoradiographic signals of late c-myc and IL-2R mRNA expression. Since we had previously ascertained that MAb 01.65 treatment induces a decrease in PKC enzymatic activity after few minutes, the correlation of that result with the data presented in this paper will be discussed.

Abstract
Monoclonal anti HLA class I antibodies inhibit the proliferative response of PHA-stimulated T lymphocytes. We studied the effects of MAb 01.65 anti-HLA class I on c-fos, c-myc and IL-2R mRNA expression. We found that MAb treatment does not modify either c-fos mRNA levels observed after 10 minutes to 3 hrs or the early c-myc mRNA expression revealed after 1 to 6 hrs, but decreases the intensity of autoradiographic signals of late c-myc and IL-2R mRNA expression. Since we had previously ascertained that MAb 01.65 treatment induces a decrease in PKC enzymatic activity after few minutes, the correlation of that result with the data presented in this paper will be discussed.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
