Furthermore, both the CSF2 +30‐kb and IL3 −34‐kb pDHSs were present in circulating human peripheral blood CD4+ CD45RA− memory‐phenotype T cells, at a level indistinguishable from C42 mouse TB, and were weak or absent in human CD4+ CD45RA+ naive T cells (Fig 1F). The gene discussed is CSF2; the disease is tuberculosis.
