Title: THE ROLE OF ACTIVE TETRAPEPTIDE OF PREGNANCY SPECIFIC GLYCOPROTEIN IN INDUCING IMMUNOTOLERANCE OF SKIN ALLOGRAFT IN MICE.

Abstract:

BACKGROUND: Pregnancy specific glycoproteins (PSGs) are synthesized by the placenta at the onset of pregnancy and are believed to play a role in maintaining a tolerogenic immune environment to prevent rejection of the fetus by the maternal immune system. Active part of PSG (tetrapeptidetyr-glu-cys-glu) was synthesized and investigated in terms of immunotolerogenic effect in mice.

MATHERIAL AND METHODS: The skin transplantation model was used to study the allograft rejection in female and male BALB\c mice. Gender-matched C57BL/ 6(H2b) mice were used as skin donors. The age of the animals was between eight and 12 weeks, weight over 20 g. The skin transplantation experiment conformed to local animal protection laws. Ten mice received intraperinoneal injection of PSG tetrapeptideduring 14-20 days and 10 mice was rest in control group. The allograft rejection was evaluated macroscopically and by histological study.

RESULTS: In control allogenic transplants, rejection times between 5 and 10 days were observed. In tetrapeptide allogenic transplants, rejection times between 14-21 days were observed and mice were stay tolerogenic until the injection of active tetrapeptide was stoped.

CONCLUSION: The active tetrapeptide of pregnancy specific glycoprotein may play role in inducing immunotolerance in transplantation. Further investigations planed to evaluate immunologic mechanisms of active tetrapeptide effects.
