CD79A and infection: Thus, consistent with previous observations, significantly more IgA+ cells (Fig. 4a; p = 0.0302, Student’s t-test) were present in the large intestine, while significantly fewer IgA+ cells (Fig. 4b; p = 0.0239, Student’s t-test) were detected in the small intestine in ΔdblGATA-1 mice compared to BALB/c mice post-infection.
