Infection of immature DCs with the Absettarov strain led to even more significant increase in the percentage of CD38 (p < 0.05), CD40 (p < 0.05), CD83 (p < 0.05), and CD11c (p < 0.05) positive cells in comparison with the negative control, but percentage of cells expressing MHCII molecule was considerably lower that after infection with EK-328 strain. This evidence concerns the gene CD40 and infection.
