Single infections with M. abscessus R, S, and B. thuringiensis showed different stimulatory capabilities, whereas M. abscessus S did not induce the production of cytokines, B. thuringiensis triggered only IL-8 production in both cell lines, M. abscessus R triggered IL-6 production in both cell lines, and IL-8 only in the control cell line (16HBE14o-) (Figure 3(b)). The gene discussed is CXCL8; the disease is infection.
