CD79A and infection: Some state that antibodies against LPS, one of the components in the HKS extract, are associated to protection by blocking adhesion of bacteria to epithelial cells (39, 40), others declare that IgA is not required for protection since IgA-deficient mice can be fully protected from infection (28), while others propose that the primary role of B cells in acquired immunity to Salmonella is via the development of protective T cell immunity (44), so the IgA increment would not be important per se but merely an immune correlate of B cell activation.
