REGULATORY TSCELLS WITH SUPPRESSIVE ACTIVITY IN SURGICAL SEPSIS
Abstract. Present work aims to investigate functioning of the regulatory T-cells with suppressor activity in surgical sepsis. It has been shown that the septic patients with decreased T cell proliferation are characterized by enhanced relative contents of СD4+СD25+ lymphocytes, including СD4-CD25hig...
