Effect of Glycodelin on the Level of T-Regulatory Lymphocytes and Acute Phase Proteins in Wistar Rats after Introduction of Allogenous Bone Marrow Cells

Abstract

Amniotic variant of glycodelin (GdA) has pronounced immunomodulatory properties, participating in the formation of immune tolerance during pregnancy. We investigated the effect of glycodelin on the level of T regulatory lymphocytes (Treg) and the level of acute phase proteins (α-2-macroglobulin (α-2M), orosomucoid, C-reactive protein (CRP)) upon administration of allogeneic red bone marrow (BM) cells to Wistar rats in a dynamic experiment in vivo. It was found that the introduction of GdA in animal whith allogeneic BM led to an increase in the proportion of peripheral Treg among CD4+ lymphocytes at the end of the experiment (on the 21st day) in comparison with the group that was injected with BM. It was shown that glycodelin reduced the level of CRP and α-2M, but increased the level of orosomucoid in the serum of experimental animals at the beginning of the experiment (day 3), however, by the end of the experiment (day 21), normalization of protein values was observed in all groups of experimental animals acute phase to the level of intact animals. Thus, glycodelin is able to realize an immunosuppressive effect on allogeneic cells through an increase in the level of Treg and orosomucoid, as well as a decrease in the concentration of CRP and α-2M.
