Recently, it has been reported that, in a mouse model of lipopolysaccharide-induced acute lung injury with increased number of total cells and neutrophils in the bronchoalveolar lavage fluid, pretreatment of human MSCs with kynurenic acid enhanced the therapeutic effect of MSCs on ALI and controlled their anti-inflammatory therapeutic effects mediated by TSG-6 (Wang et al. 2018). The gene discussed is TNFAIP6; the disease is injury.
