IL1B and ischemic stroke: Several studies have found that inhibition of IL-1β could cause significantly decreases in infarct volume (up to 60% to 70%) in MCAO mice and rats (Boutin et al., 2001; Touzani et al., 2002; Lambertsen et al., 2012), and increased level of IL-18 may contribute to the development and severity of ischemic stroke (Hao et al., 2019).This study referred that QNDP therapy obviously decreased the protein and mRNA expression of IL-1β and IL-18, and further demonstrated the notable intervention of QNDP on inflammatory response in cerebral ischemia based on our precious study(Zeng et al., 2019).
