Other studies have demonstrated potential benefits of NA administration in rodent models, including lower levels of IL-4 and IL-13 in an asthma animal model [18], decreased TGF-β1 in a renal injury model [16,19,20], and decreased inflammation of rat skin induced by ultra-violet radiation, which led to the reduction of several interleukins, TNF-α, and TGF-β1 [21,22]. This evidence concerns the gene TGFB1 and asthma.
