Markers of Macrophage Infiltration and Measures of ...- adipose tissue macrophages markers ,Adipose tissue macrophage (ATM) content seems to contribute to both local and systemic inflammation (4), and has been implicated in the de- velopment of obesity-linked comorbidities such as insulin resistance and nonalcoholic fatty liver disease (5). CD68, CD11b, and CD11c are surface markers involved in the binding of antigens, adhesionLymphocytes and macrophages in adipose tissue in obesity ...Feb 01, 2017·In contrast to lean state, obesity is characterized by increased number of pro-inflammatory M1 macrophages in adipose tissue (Aron-Wisnewsky et al. 2009). However, adipose tissue macrophages and also the ratio of M1 and M2 macrophages could be reduced in adipose tissue by body weight reduction (Aron-Wisnewsky et al. 2009; Kovacikova et al. …
Adipose Tissue Macrophages - an overview | …
Adipose tissue macrophages are classified into two major subtypes: M1 and M2. A concept of M1/M2 polarization has been developed based on expression patterns of cytokines, surface markers, and metabolic enzymes.70 M1 macrophages are potent effector cells that produce inflammatory cytokines, such as TNF-α, IL1-β, and IL-6.

Objective: Adipose tissue (AT) macrophages are increased in obesity and associated with low grade inflammation. We aimed to characterize the phenotype of AT macrophages in humans in relation to obesity and insulin resistance. Design: Gene-expression levels of general macrophage markers (CD68 and CD14), proinflammatory markers/M1 (TNF-α, MCP-1, and IL-6), and anti …
