Short linear peptide fragments of placental trophoblastic β1-glycoprotein (PSG) (YECE, YQCE, YVCS, and YACS) were studied in the context of their immunomodulatory effects at the level of inflammatory markers. The original host-versus-graft model was used in male Wistar rats without prior conditioning of recipient bone marrow. A composition of PSG peptide fragments was injected to animals after allogeneic transplantation of bone marrow cells in a dynamic experiment, inflammatory markers α1-acid glycoprotein (AGP, orosomucoid), α2-macroglobulin (α2M) were assayed by ELISA, and biochemical parameters (total protein, glucose, creatinine, and urea) were measured.
