Analysis of serum cytokines, however, did show cytokine release syndrome (CRS) with statistically significant increases in IL-6, IL-10 and IL-12p70 and a decrease in TNFα noted 1 and/or 2 weeks after ex vivo activated NK infusion as compared to recipients of allogeneic HSCT alone (Figure 5). The gene discussed is IL6; the disease is congenital rubella syndrome.
