On the other hand, human targets, including many kinases, e.g., adaptor-associated kinase 1 (AAK1), cathepsin L, and the transmembrane serine protease 2 (TMPRSS2), are involved in the advancement of symptoms associated with SARS-CoV-2 infections, such as pneumonia, inflammation, and fibrosis [13]. This evidence concerns the gene TMPRSS2 and pneumonia.
