Among the genes encoding molecules involved in innate antiviral immunity such as chemokines and their receptors or TLR, which are associated with the complicated course of COVID-19, fluvastatin directly affected the expression of the TLR4 gene (log2FC = 1.00; p-value ˂ 10−9) in AD-MSC cells (Figure 2). This evidence concerns the gene TLR4 and COVID-19.
