Interestingly, and as observed after infection of mice with H. pylori, the expression of the chemokines CXCL9 and CXCL10 was strongly reduced in BCG-infected BATF3-deficient compared to WT mice (Fig 2K), whereas CXCL11 expression was unaffected by the BCG infection or the mouse genotype (S2B Fig). The gene discussed is BATF3; the disease is infection.
