TGFB1 and coccidiosis: Our previous study identified salinomycin as a powerful antiscarring agent, which effectively blocked TGF-β–driven fibroblast proliferation and myofibroblast formation in vitro.18 Salinomycin is a polyether ionophore that has been approved for coccidiosis control and promotion of animal growth and feed efficiency.19 Although this previous study showed that salinomycin possesses anti-TGF-β activity and reduced myofibroblast activity in vitro, there are needs to find additional therapeutic small molecule drugs which may be easier to develop and synthesize.
