Abstract

In recent times the question of the bidirectional interactions of the neuroendocrine and immune systems is studied quite actively, its mechanisms offer the opportunity to allow for optimization the therapy of several diseases, including Parkinson’s disease. The purpose of this work is to study the influence of peptide drugs derived from the body’s immune system, the thymus, for the avoidance test conditioning, both in health and in the model of Parkinson-like syndrome. The work was performed on 80 male Wistar rats weighing 300-350 g. The injection of thymosin fraction 5 and thymalin to animals corrects clinical traits and behavioral dysfunctions caused by the singular injection of the neurotoxin. It also facilitates conditioned active evasion response in rats, which is especially noticeable at the early stages of memory footprint formation.
