Cytokine storm generated by new coronavirus pneumonia (COVID-19) (Liu et al., 2020; Zhang et al., 2020). LNT, alternatively, has robust regulatory effects on IL-1b and IL-6, andFrontiers in Cellular and Infection Microbiology | frontiersin.orgMay 2022 | Volume 12 | ArticleCui et al.Anti-Influenza Effect of LentinanFIGURE 8 | LNT regulates the cytokine storm by way of the TLR4 signaling pathway and alleviates acute lung injury brought on by influenza virus infection. This figure was drawn on Figdraw.some researchers have postulated that it might also regulate COVID-19 (Murphy et al., 2020). As a result, scientists must examine whether LNT includes a regulatory influence on COVID-19. TLR4 is involved inside the inflammatory response to IAV infection, and activation in the TLR4 signaling pathway exacerbates the lung damage induced by the virus (Imai et al.IGF-I/IGF-1, Mouse , 2008; Martin and Wurfel, 2008; Nhu et al.GRO-alpha/CXCL1 Protein Formulation , 2010). Within the TLR4 signaling pathway, that is necessary for cytokine generation, MyD88 serves as a crucial bridge protein (Yamamoto et al., 2003; Deguine and Barton, 2014). TRAF-6 triggers NF-kB, which causes gene expression and inflammatory cytokine secretion (Downes and Marshall-Clarke, 2010). You will discover quite a few members of TLRs, including TLR3, TLR7, etc. In our study, no other TLRs had been identified to play a vital function in the anti-influenza approach of lentinan. LNT regulates sepsis through the TLR4/MyD88 signaling pathway, in accordance with prior research (Li et al., 2020; Kuang et al., 2021). The TLR4/MyD88 signaling pathway was investigated working with RT PCR and immunohistochemistry within this study. Our findings revealed that LNT reduces the severity of pneumonia induced by IAV infection by modulating the TLR4/ MyD88 signaling pathway, resulting within a much more efficient therapeutic effect (Figure eight). In conclusion, our findings reveal that LNT can cut down ALI in IAV-infected mice, and we studied the mechanism of LNT action by inhibiting the inflammatory response by controlling the TLR4/MyD88 signaling pathway. This research laid the groundwork for the clinical use of LNT plus the development of novel immunomodulators.Information AVAILABILITY STATEMENTThe original contributions presented inside the study are incorporated inside the article/supplementary material.
