生化/生理作用
粒细胞-巨噬细胞集落刺激因子（GM-CSF）是粒细胞、巨噬细胞和嗜酸性粒细胞系的生长和分化因子。GM-CSF 在极低浓度下刺激多能祖细胞集落形成，是造血祖细胞直至成熟的所有分裂中必不可少的存活和增殖因子。它也刺激一些上皮细胞和破骨细胞的生长。GM-CSF 由多种细胞类型（单核细胞、内皮细胞、T 细胞、成纤维细胞、有丝分裂原刺激的 B 细胞和 LPS 刺激的巨噬细胞）产生。GM-CSF 是一种单链糖蛋白，含有 128 个氨基酸，具有保守的二硫键。人和鼠 GM-CSF 的序列同源性约为 54%，生物活性无交叉反应。

Specificity of signaling by hematopoietic cytokine receptors: instructive versus permissive effects.
R C Skoda
Journal of receptor and signal transduction research, 19(1-4), 741-772 (1999-03-11)
The helical cytokines constitute a family of proteins with a common three-dimensional structure. They exert a wide variety of biological effects with a preference for the hematopoietic system. The effects of helical cytokines are mediated by cell surface receptors, which

The process of ligand binding leading to receptor activation is an ordered and sequential one. High-affinity binding of GM-CSF, interleukin 3 (IL-3), and IL-5 to their receptors induces a number of key events at the cell surface and within the

The Jak-STAT pathway was originally discovered through the study of interferon induced intracellular signal transduction. Meanwhile, a large number of cytokines, hormones and growth factors have been found to activate Jaks and STATs. Jaks (Janus Kinases) are a unique class

Microglia are CNS resident immune cells and a rich source of neuroactive mediators, but their contribution to physiological brain processes such as synaptic plasticity, learning, and memory is not fully understood. In this study, we used mice with partial depletion

Cytokines participate in the induction and effector phases of all immune and inflammatory responses. They are therefore obvious tools and targets for strategies designed to promote, inhibit or redirect these responses. However, the complexity of the cytokine network has hindered
