作者观察到,用细胞因子刺激培养物中的骨髓源性巨噬细胞 (BMDM) 诱导 M1 或 M2 极化,显示出明显不同的细胞形态。添加 LPS 和 IFN-γ 会刺激 M1 极化,导致细胞在刺激后 24 小时内变平成圆形、煎饼状。相反,添加刺激 M2 极化的 IL-4 和 IL-13 会导致细胞伸长(图 1A)。细胞伸长程度的量化(作者将其定义为...
巨噬细胞Macrophages一个重要的特性就是具有很高的可塑性(通俗的讲就是多变,随所处环境的变化而变),面对不同的病原体或刺激因素时可以向不同方向分化。根据极化后巨噬细胞的表面标志物及其功能,将其分为M1型(经典活化)巨噬细胞和M2型(替代激活)巨噬细胞两种主要表型。切记,巨噬细胞macrophages的极化M1和M2是机...
巨噬细胞Macrophages的起源和经典分类M1/M2来源:靶点科技(北京)有限公司 2024年10月27日 11:53 分享 巨噬细胞Macrophages是通过吞噬病原体及其生理/病理产物来维持稳态的细胞。巨噬细胞的形态取决于细胞的各种活动状态。巨噬细胞的大小直径在 10-30 µm 之间。于1884年由科学家伊里亚·梅钦科夫(Ilya Mech...
在降维聚类分群后的umap图里面,M1和M2它们的界限并不是很清晰,而且在气泡图里面CD86和CD163的表达量也不是说在CD86和CD163里面互斥,仅仅是表达量的些微高低而已。 能泾渭分明的巨噬细胞分类 2022的一篇CELL文章:《Tissue-resident FOLR2+ macrophages associate with CD8+ T cell infiltration in human breast canc...
The culture supernate of M1 and M2 macrophages was collected and co-cultured with the PDGFRα preadipocytes. After 3 days, Oil Red O staining was used to evaluate to adipogenic differentiation of PDGFRα preadipocytes and the expression of adipogenic-related transcription factors (C/EBP-α, ...
Chronic disorders associated with low-grade inflammatory responses are characterized by presence of pro-inflammatory mediators that induce the recruitment and activation of predominantly M1 macrophages in the metabolically active tissues. In this study, we show that anthocyanin-treated macrophages developed a...

M1 is to macrophages as Th1 is to lymphocytes; among other cytokines, Th1 cells can produce high levels of IFN-γ, an extremely potent macrophage chemoattractant, and also one of the most potent endogenous M1 macrophage activation stimuli. LPS (endotoxin) from bacteria can also stimulate M1 (or...

Dysfunctional megakaryopoiesis hampers platelet production, which is closely associated with thrombocytopenia (PT). Macrophages (MФs) are crucial cellular components in the bone marrow (BM) microenvironment. However, the specific effects of M1 MФs or M2 MФs on regulating megakaryocytes (MKs) ar...
