IL10 and infection: To elucidate the mechanism of BCG infection induced increase in IL-10 production in the AAMs but not in the CAMs, the pre-infection IL-10 production (using LuminexTM) and the relative mRNA expression (using qRT-PCR) of the important adaptor molecules involved in IL-10 regulation was contrasted with responses at 1,4,6,18 and 24 hours post infection within CAMs and AAMs.
