生化/生理作用

白介素-4是对免疫活性细胞的生长和分化具有明显的影响的淋巴因子。IL-4又称B细胞刺激因子-1(BSF-1)、T细胞生长因子-2(TCGF-2)和肥大细胞生长因子-2(MCGF-2)。抑制VEGF和bFGF诱导的血管生成。 IL-4是由活化的T细胞亚群释放的复合糖蛋白。人和小鼠 IL-4 具有50%的氨基酸序列同源性,但它们的生物学作用是物种特异性的。

Neurogenesis, the production of new neurons from neural stem/progenitor cells (NSPCs), occurs throughout adulthood in the dentate gyrus of the hippocampus, where it supports learning and memory. The innate and adaptive immune systems are increasingly recognized as important modulators of

Cellular responses to both physiological and pathological DNA double-strand breaks are initiated through activation of the evolutionarily conserved ataxia telangiectasia mutated (ATM) kinase. Upon DNA damage, an activation mechanism involving autophosphorylation has been reported to allow ATM to phosphorylate downstream

It has been shown that Faecalibacterium prausnitzii (F. prausnitzii), one of the dominant intestinal bacterial flora, may protect colonic mucosa against the development of inflammation and subsequent inflammatory bowel disease (IBD), with the underlying mechanisms being unclear. The impacts of

Ex vivo engineered three-dimensional organotypic cultures have enabled the real-time study and control of biological functioning of mammalian tissues. Organs of broad interest where its architectural, cellular, and molecular complexity has prevented progress in ex vivo engineering are the secondary immune organs.

Maturation as well as antigen-dependent activation of B cells is accompanied by alternating phases of proliferation and quiescence. We and others have previously shown that Krüppel-like factor 2 (KLF2), a regulator of T cell quiescence and migration, is upregulated in
