生化/生理作用

白介素3(IL-3)是一种多功能蛋白,起初被称为克隆形成单位刺激活性(CFU-SA),由活化的T淋巴细胞产生。IL-3在多能造血祖细胞的早期发育中可支持多谱系克隆的形成。IL-3已显示出可从琼脂悬浮的骨髓细胞诱导巨噬细胞、嗜中性粒细胞、肥大细胞和巨核细胞的克隆形成。IL-3也可与IL-2发生互作,以刺激T淋巴细胞的生长并诱导活化B细胞分泌IgG。IL-3的其他同义词包括泛特异性造血素、多克隆刺激因子、肥大细胞生长因子、爆发促进活性、组胺生成细胞刺激因子、P细胞刺激因子和WEHI-3因子。

Ribosomal protein dysfunction causes diverse human diseases, including Diamond-Blackfan anemia (DBA). Despite the universal need for ribosomes in all cell types, the mechanisms underlying ribosomopathies, which are characterized by tissue-specific defects, are still poorly understood. In the present study, we

Basophils are primarily associated with immunomodulatory functions in allergic diseases and parasitic infections. Recently, it has been demonstrated that both activated human and mouse basophils can form extracellular DNA traps (BETs) containing mitochondrial DNA and granule proteins. In this report

Impaired megakaryocyte maturation and insufficient platelet production have been shown to participate in the pathogenesis of immune thrombocytopenia (ITP). Our previous study demonstrated that low expression of tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) in megakaryocytes contributed to impaired platelet production

In addition to serving as a prosthetic group for enzymes and a hemoglobin structural component, heme is a crucial homeostatic regulator of erythroid cell development and function. While lncRNAs modulate diverse physiological and pathological cellular processes, their involvement in heme-dependent

Toll-like receptors are sensing modulators of the innate immune system. One member of this protein family, Toll-like receptor (TLR)-9, is increasingly being investigated as therapeutic target for infectious diseases and cancer. Double-Stem Loop ImmunoModulator (dSLIM) is a new TLR-9 agonist

The Interleukins comprise a disparate group of cytokines and growth factors that are produced by and released from leukocytes. Interleukin-1β (1L-1β) is released primarily from stimulated macrophages and monocytes and plays a key role in inflammatory and immune responses and may induce anti-tumor immunity.
