We studied the role of native α-fetoprotein preparation in the regulation of proliferation and functional activity of naïve T cells and immune memory T cells in vitro. The study was carried out on separated fractions of naïve T cells (CD45RA+) and immune memory T cells (CD45R0+) incubated with α-fetoprotein under conditions of TCR activation. At the level of naïve T cells, α-fetoprotein in a concentration of 100 U/ml reduced the expression of CD28, but increased the expression of CD25, while at the level of immune memory T cells α-fetoprotein (50 and 100 U/ml) only suppressed the expression of CD25. No effects of α-fetoprotein on the proliferative status of the studied lymphocyte subpopulations and on the expression of CD71 (proliferation marker) by these cells were detected. Addition of α-fetoprotein in a concentration of 100 U/ml increased the level of IL-2 in naïve T cell culture supernatants, while production of IL-2 by memory T cells remained unchanged. These data demonstrated the priority aspects of regulation of the functional activities of naïve T cells and immune memory T cells.
