关于TGF-α：
Transforming Growth Factor α (TGF-α) belongs to the EGF family of cytokines. It is a mitogenic polypeptide and secreted protein, which is expressed by monocytes, keratinocytes, and various tumor cells. TGFα contains two chains, protransforming growth factor α and transforming growth factor α. It can bind to the EGF receptor that synergistically with TGFβ to stimulate anchorage-independent cell proliferation and produce a mitogenic response. TGFα interacts with the PDZ domains of MAGI3, SDCBP and SNTA1. The interaction with SDCBP is required for the targeting to the cell surface.

关于PIgR：
The human Polymeric Immunoglobulin Receptor (pIgR) is a 100 kDa type I transmembrane glycoprotein. Its precursor is 764 amino acids. It contains an 18 amino acid signal sequence, a 620 amino acid extracellular region, a 23 amino acid transmembrane fragment, and a 103 amino acid cytoplasmic domain. pIgR is synthesized by secretory epithelial cells with five Ig-like domains in extracellular region, and transfer to the basolateral plasma membrane. For IgA and IgM polymers, in addition to α-heavy chains and light Ig chains, a short polypeptide named joining chain (J chain) is also contained and required. pIgR can bind larger polymers of IgA (pIgA) and pentameric IgM as a carrier that transports IgA and IgM across epithelium. The receptor-ligand complexes are endocytosed and transcytosed to the apical surface, then proteolytic cleavage of the sixth extracellular domain of pIgR and generate secretory IgA (SIgA), the pIgR fragment is referred to as secretory component (SC). SIgA is a important component of the mucosal immune system. SC is anti-microbial properties and protects SIgA from proteolytic degradation
