IL-4 促进 B 细胞 MHCⅡ类抗原、FcεRⅡ/CD23 和 CD40 的表达,并增强 B 细胞提呈抗原能力,使免疫系统对小量抗原刺激发生免疫应答。 增加 FcεRⅡ/CD23 (IgE Fc 段低亲和力受体) 的表达,并释放可溶性 CD23 (sCD23)/IgE 结合因子 (IgE-BF),与 mIgE 阳性细胞结合并诱导其分化,可能与促进B细胞 IgE 的产生有关。 IL-4 提高 LPS 刺激小鼠 B 细胞 IgG1、IgE 产生水平分别为 8~10 倍和 10~100 倍,但对 IgG3 分泌降低 6~10 倍,IgG2a、IgG2b 和 IgM 有不同程度下 …
CD4+/IL‑4+ lymphocytes of the lamina propria and substance P …
Moreover, it was found that acute stress caused a shift towards a predominantly anti‑inflammatory immune response (T helper 2 cells), as shown by the increase in the percentage of CD4 + /IL‑6 + and CD4 + /IL4 + lymphocytes in the lamina propria and the increase in serum SP.

The differential expression of IL-4 and IL-13 and its impact on …
This review summarizes the literature surrounding the function and expression of IL-4 and IL-13 in CD4+ T cells and innate immune cells. It highlights recent in vivo findings regarding the differential expression and non-canonical regulation of IL-4 and IL-13 in various immune cells, which likely play an underappreciated and important role in ...
Frontiers | IL-4 Is a Key Requirement for IL-4- and IL-4/IL-13 ...
We sought to better define IL-4’s role in CD4 Th2 responses by using transgenic mice that express a dual IL-4 AmCyan/IL-13 DsRed (IL-4AC/IL-13DR) fluorescent reporter on an IL-4-sufficient or IL-4-deficient background.
Recent advances in understanding the role of IL-4 signaling
IL-4 induces elevated cell surface expression of CD23 (the low-affinity IgE receptor) on B cells and of class II major histocompatibility complex (MHC) molecules. In addition, IL-4 acts as a T-cell growth factor in both humans and mice and promotes the differentiation of Th2 cells.
IL-4 drives exhaustion of CD8 + CART cells - Nature
2024年9月12日 · Further, IL-4-treated CD8 + CART cells develop signs of exhaustion independently of the presence of CD4 + CART cells. Conversely, IL-4 pathway editing or the combination of CART cells with an...

STAT3 determines IL-4 signalling outcomes in naïve T cells
2021年5月18日 · Mounting evidence indicates that cells can dynamically alter their IL-4/IL-13 receptor signature to modulate downstream immune outcomes upon pathogen encounter. Here, we describe how naïve (CD62L...
The type 2 cytokine Fc–IL-4 revitalizes exhausted CD8 - Nature
2024年9月25日 · Here we show that an interleukin-4 fusion protein (Fc–IL-4), a typical type 2 cytokine, directly acts on CD8 + T cells and enriches functional terminally exhausted CD8 + T (CD8 + T TE)...
