Human cord blood cells were shown to produce interferon-alpha- and -gamma in vitro, both spontaneously and following adequate induction. Transplantation of human blood cord cells to mice led to endogenous interferonogenesis activation, serum interferon levels as well as interferon-alpha and interferon-gamma synthesis by activated peripheral blood leucocytes becoming higher. The maximal interferon accumulation in murine blood sera following transplantation did not coincide with interferonogenesis dynamics observed due to the effect of standard early and late interferon inducers - poly I:C and ridostin, respectively. Interferonogenesis activation was accompanied by increased functional activty of phagocytic system cells.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
