最新研究進展：

IL-4是一種細胞因子，它在機體免疫反應中發揮重要作用，特別是在過敏和響應寄生蟲感染時。近年來的研究表明，IL-4在多種疾病的發生和發展中也具有潛在的作用。例如，在腫瘤中，IL-4能夠刺激免疫細胞對腫瘤細胞的殺傷作用，因此被視為一種潛在的腫瘤免疫治療藥物。此外，IL-4還被發現在許多自身免疫性疾病中表達水平升高，如類風濕關節炎、多發性硬化癥等，因此也成為這些疾病治療的研究熱點之一。
功能：

Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. Positively regulates IL31RA expression in macrophages. Stimulates autophagy in dendritic cells by interfering with mTORC1 signaling and through the induction of RUFY4.
