Markers such as CD11b, CD11c, F4/80, Gr-1, Ly6C, and Ly6G have long been used to identify various splenic cell myeloid populations. Flow cytometry and fluorescence-activated cell sorting (FACS) analysis demonstrated that Ly6G/Ly6C markers are superior to Gr-1 for identifying splenic neutrophils, eosinophils, and subsets of monocytes/macrophages. Moreover, these experiments showed that F4/80 is not required for identifying these myeloid subsets and that many of the commercially available Ly6C Hi Blood Monocyte/Macrophage Drive Chronic Inflammation and Impair Wound Healing in Diabetes Mellitus. Collectively, these data identify kinetic and functional differences in diabetic wound monocyte/macrophages and demonstrate that selective targeting of CD11b⁺Ly6C^Hi monocyte/macrophages is a viable therapeutic strategy for inflammation in diabetic wounds. Because Ly6C Lo [Lin − Ly6G − CD11b +] monocyte/macrophages represent more of a hybrid picture between in vitro M1 and M2 macrophages, it is possible that the use of traditional in vitro macrophage characterization for this cell population in wound healing is not practical, as has been previously suggested. 21 These findings are highly relevant as they will allow for more accurate immunophenotyping of wound monocyte/macrophages and identify new avenues for therapy. Ly6G is a glycosylphosphatidylinositol‐linked cell‐surface protein that is expressed predominantly on murine neutrophils .

The Ly6C+Ly6G- (top, open histograms) and Ly6C+Ly6G+ (bottom, open histograms) CD11b+ monocyte subpopulations were analyzed for the expression of various cytokines/effector molecules using antibodies (A-D) or a reactive dye triggered by exposure to ROS (E) and compared to CD11b- cells (filled histograms). Ly6G, a granulocyte surface marker, is the major antigen detected by RB6‐8C5 [ 12 ].

The Ly6C Int Ly6G − SSC Hi population consisted almost entirely of eosinophils with very rare monocytes/macrophages (Figs.

We found that C-C chemokine receptor type 2 (CCR2) deficiency, which blocks the migration of Ly6C+ macrophages from the bone marrow to the sites of injury, alleviated ischemia-induced AKI in mice. 2017-10-31 · Interestingly, resident Ly6C-Ly6G-CD11b+ macrophages were also infected, however they represented the least infected cells among the three populations (Fig. 1C–F). Gr1 is an antibody against Ly6G (granulocyte marker) and Ly6C (macrophage marker) - both are of the Ly6 family of GPI anchor proteins.

Using flow-sorted tdTomato-labeled Ly6CHimonocyte/macrophages, we show Ly6CHicells transition to a Ly6CLophenotype in normal wounds, whereas in diabetic wounds, there is a late, second influx of Ly6CHicells that fail transition to Ly6CLo.

2017-06-26 · Rather, they overwhelmingly appear to be derived from active recruitment of recipient monocytes from the Ly6C hi subset. Although M2 macrophages have been proposed to arise from either the Ly6C lo subset or from proliferation of tissue macrophages derived from the yolk sac , our findings are in agreement with recent reports that Ly6C hi inflammatory monocytes recruited to allergic skin, schistosome granulomas, or injured myocardium subsequently acquired the M2 phenotype (20, 28 The number of retrieved anti‐Ly6G‐FITC + cells was reduced significantly in comparison with anti‐Ly6G‐APC + or anti‐Ly6G‐PE + cells. Flow cytometry and multispectral imaging flow cytometry analyses revealed that anti‐Ly6G‐FITC + neutrophils were preferentially phagocytosed by BMMs in vitro and by splenic, hepatic, and BM macrophages in vivo. One specific marker for neutrophils is Ly6G(Clone 1A8).

Pro-inflammatory monocytes could also convert to anti-inflammatory M2-type macrophages in an allergic response via basophil-derived IL-4 ( 34 ). macrophages, having an enlarged macrophage-like scatter and expressing high levels of F4/80 (Fig. 1A and D). Remark-ably, distinct subsets of TAMs were clearly distinguishable: Ly6C intMHC IIhi (Ly6C TAMs, gate 2), Ly6ClowMHC IIhi (MHC IIhi TAMs, gate 3), and Ly6ClowMHC IIlow (MHC IIlow TAMs,gate4).ThemajorityofLy6ClowMHC II− cells were CCR3 CD11b+Ly6C high (Ly6Chi) cells (inflammatory monocytes) and CD11b+Ly6C low cells (reparative monocytes) were recruited into the liver following I/R injury.
