Interestingly, and in line with increased levels of IL-5 and IL-10 in cultured splenocytes of M. vaccae NCTC 11659T-treated mice [40], which correlated with decreased lung eosinophilia, numbers of IL-10 producing Tregs were also elevated following M. vaccae NCTC 11659 treatment [40]. The gene discussed is IL10; the disease is Increased total eosinophil count.
