The objective of the present study was to assess the level of 26 cytokines secreted by peripheral blood cells of the patients with liver cirrhosis (LC; n = 20) during the cell therapy (CT). All the patients were administered with intravenously injected autologous bone marrow-derived mononuclear cells (MNCs) in a dose of 1.3±0.3 × 109 (Ме 1.0 × 109 ) followed by 14 days later intravenous injection of ex vivo generated mesenchymal stromal cells (MSCs) in a dose of 22.3±5.0 × 106 (Ме 16.0 × 106 ). The patients were examined before the CT, 2-3 days after the administration of MNCs and, then, 2-3 days after the introduction of MSCs. Cytokine-secretory function of peripheral blood cells was evaluated in a 24-hour whole blood cultures both in the absence of any stimulation and in response to lipopolysaccharide (LPS). The control group consisted of 10 healthy donors. The administration of patients’ bone marrow cells (both MNCs and MSC) was safe and well tolerated and caused no any adverse (toxic or allergic) events. Compared with donors, LC patients (especially, with class B+C by Child-Pugh) differed by an initially increased production of several cytokines and chemokines. Actually, there was a statistically significant increase of the spontaneous production of IL-9, MIP-1β, and IP-10, as well as a distinct trend to an increase in TNFα, IL-1ra, IL-4, IL-5, IL-6, IL-13, of MCP-1, MIP-1α, RANTES and Eotaxin. Moreover, the blood cells of LC patients were susceptible to the stimulatory effect of LPS, and the LPS-induced production of 11 out of 26 cytokines (IL-1ra, IL-6, IL-9, IL-15, IL-17, IL-7, IL-8, IP-10, MIP-1α, MIP-1β, Eotaxin) significantly exceeded the normative values. Transplantation of bone marrow MNCs had minimal impact on cytokine production. Meanwhile, the MSCs introduction resulted in a significant decrease in spontaneous and LPS-induced production of, respectively, 20 and 18 analytes including pro-/anti-inflammatory and immunoregulatory cytokines, chemokines and growth factors. The normalization of cytokine-secretory function following transplantation of MSCs revealed in the patients with LC indicates the weakening of an inflammatory activity of circulating blood cells and the decrease in their reactivity to endotoxin. MSC suppressive effect on cytokine production was dose-dependent, and most pronounced in patients with decompensated LC (class B+C by Child-Pugh) of viral etiology.
