Abstract:
Objective To study the effect of prolactin(PRL) on the activation of T lymphocytes stmiulated by concanavalin A(ConA),and to explore the action of PRL in the activation of T lymphocytes. Methods After CD4 +T cell line JurkatE6-1 cells were respectively stmiulated by 5 mg/L ConA,25 ?g/L PRL and 500 ?g/L bromocriptine(Brc).The blank control group,the ConA group,the PRL and ConA group(PRL group),the Brc and ConA group(Brc group),the PRL and Brc group(PRL-Brc group) were set in the experiment.The total RNA was extracted by Trizol after 48 hours and was reversed transcription immediately.The expression of tumor necrosis factor receptor associated factor 6(TRAF6) mRNA of T lymphocytes was checked by PCR.The expressions of tumor necrosis factor(ligand) super family 4(TNFSF4) and Killer specific secretory protein of 37 000(KSP37) mRNA of T lymphocytes were detected by real-time polymerase chain reaction. Results The PRL group and the Brc group could inhibit the expressions of TRAF6,TNFSF4,and KSP37 mRNA of the activated T lymphocyte compared with the blank control group and the ConA group(P a0.05).The PRL-Brc group could inhibit significantly the expressions of TRAF6,TNFSF4,and KSP37 mRNA of the activated T lymphocyte compared with the ConA group(P a
