TGFB1 and infection: Early-response immune (neutrophils) cell counts that were reduced on day 1 and late-response immune cell (monocytes, interstitial macrophages, and B cells) counts that were reduced on day 3 by LDRT increased in the anti-TGF-β mAb-treated group to a level similar to that in the untreated mice (infection + mouse IgG group, Figure 5E).
