human APRIL, MBP/His-Tag Species_SARS-CoV-2; Wuhan seafood market pneumonia virus SNNLDSKVGGNYNYLFRLFRKSNLKPFERDISTEIYQAGSTPCNGVEGFNCYFPLQSYGFA proliferation inducing ligand (APRIL), also known as tumor necrosis factor ligand superfamily member 13 (TNFSF13), plays a key role in promoting the survival, proliferation and differentiation of B cells, thereby contributing to the maintenance of humoral immunity. Moreover, APRIL induces class switch recombination to immunoglobulin A (IgA), which is crucial for the generation of mucosal immunity and defense against pathogens at mucosal surfaces.
