title: [The promoting research of phospholipase C epsilon-1 on nasal Th2 cell polarization].
abstract: Phospholipase C epsilon-1 (PLCE1) is a phospholipase C isoenzyme encoded by PLCE1 gene, and has more complicated molecular structure and function than other subtypes. Phospholipase C epsilon-1 is accepted the dual regulation by the upstream G proteins and GTP enzymes of Ras family. The downstream signal of PLCE1 is not only cause the Ca2+ flow and protein kinase C(PKC) activation, but also can be used as the GTP enzyme guanylic acid conversion factor of Ras superfamily, so as to regulate the expression of certain genes, adjusting cell growth and differentiation processes. PLCE1 plays a very important role in the signal transduction in the regulation of cell growth, differentiation, proliferation and apoptosis. Previous studies showed that phospholipase C epsilon-1 played an important role in the development of malignant tumors (especially the digestive tumors), heart disease, nephrotic syndrome and other diseases, but there are some questions about the mechanisms of PLCE1 involved in allergic rhinitis, this article will make an overview about PLCE1 promotes allergic rhinitis CD4+ T cells differentiate to Th2 cells by PKC-NF-κB pathway and Ras-MAPK pathway.
