DYNAMICS OF IL-2 PLASMA LEVELS IN HIV PATIENTS WITH CONSIDERING DRUGS RESISTANCE

Interleukin-2 (IL-2) is one of the most important cytokines involved in the regulation of innate and adaptive immunity. Its main immunological function is to regulate a specific (antigen-dependent) immune response by stimulating proliferation and differentiation of immune cells involved in its re...

The content of IL-2 is statistically significantly lower in the group of patients who did not succeed with antiretroviral therapy than in the group of patients with treatment efficacy (1.83±0.29 pg/ml versus 4.89±0.55 pg/ml, respectively, p < 0.001, U-criterion).
