Functional Characterization of Regulatory Macrophages That

LIMITATIONS This protocol meets the basic needs for analyzing myeloid cells in most organs, but was not optimized for all organs. Ly6C, and Ly6G have long been used to identify various splenic cell myeloid popula-. tions. Flow cytometry and fluorescence-activated cell sorting (FACS) analysis demon-. strated that Ly6G/Ly6C markers are superior to Gr-1 for identifying splenic neutrophils, eosinophils, and subsets of monocytes/macrophages. One specific marker for neutrophils is Ly6G(Clone 1A8). Eosinophils and monocytes are negative for this marker.

Product Specific Information Description: The monoclonal antibody HK1.4 recognizes mouse Ly-6C, a GPI-linked protein of the Ly6 family. Ly-6C is found on monocytes/macrophages, endothelial cells and granulocytes as well as a subset of lymphocytes. (B) Gating strategy of gut macrophages (CD45 + Ly6G − Siglec F − CD11b + CD64 + CD11c int MHCII + Ly6C −) of 8-week-old mice.

We sequenced RNA in mouse CD11b + Ly6G − Ly6C high and CD11b + Ly6G − Ly6C low monocytes sorted from WT whole blood. Sorted cells (200 000/monocyte subset) were collected in 1400 μL QIAzol Lysis Reagent (Qiagen, Germantown, MD) and total RNA (50–100 ng) was isolated manually per manufacturer’s protocol. (D) Representative FACS plots of CD11b+,Ly6G+Ly6C- neutrophils, Ly6C high Ly6G- monocytes, and F4/80+ macrophages in the blood of CVB3-infected mice treated with anti-Ly6G or anti-Gr1 on day7 p.i. (pre The following markers were used: CD45 low , CD11b + , F4/80 + , Ly6C − , Ly6G − for microglia, and CD45 high , CD11b + , F4/80 + , Ly6C − , Ly6G − for macrophages, relative to total viable single cells in dissociated retina.

Eosinophils and monocytes are negative for this marker. Neutrophils: CD11c- CD11b+ Ly6G+ , Monocytes: CD11b+ CD11c- Ly6c + - ly6G -. Overall, in the tissues examined in this study, we found that cells with high Ly6C surface expression proliferate more compared to those without, as only Ly6Chi/+ Mo and/or MΦ were found in S/G2/M phases, which suggests the inflammatory Ly6C+ cells may have greater proliferating potential compared to more mature Ly6C- cells. Ly6G (Lymphocyte antigen 6 complex locus G6D) is a 21-25kD glycosylphosphatidylinositol (GPI)-linked differentiation antigen that is expressed by myeloid-derived cells in a tightly developmentally-regulated manner in the bone marrow. Monocytes express Ly6G transiently during bone marrow development, while Ly6G expression in granulocytes and peripheral neutrophils directly correlates with the Gr1 is an antibody against Ly6G (granulocyte marker) and Ly6C (macrophage marker) - both are of the Ly6 family of GPI anchor proteins.

The CD11b + Ly6C hi Ly6G − cells exhibited a mononuclear morphology, whereas the CD11b + Ly6C int Ly6G + cells exhibited a polymorphonuclear or band-shaped nuclear morphology. The CD11b + Ly6C hi Ly6G − cells differentiated into macrophage-like cells following ex vivo culture and could present antigen to T cells in vitro. Histograms: Wound cells were stained with Gr‐1, F4/80, and Ly6C or Ly6G. Neutrophils (R1, Gr‐1 high F4/80 neg cells) express Ly6C and Ly6G; macrophages (R2, Gr‐1 int F4/80 + cells) express Ly6C but not Ly6G.

CD11b+Ly6C high (Ly6Chi) cells (inflammatory monocytes) and CD11b+Ly6C low cells (reparative monocytes) were recruited into the liver following I/R injury. Treatment with clodronate‑loaded liposomes, which transiently deplete systemic macrophages, alleviated hepatic damage. Ly6G is expressed differentially during development by cells in the myeloid lineage including monocytes, macrophages, granulocytes, and neutrophils.

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.

Although macrophages are widely recognized to have a profibrotic role in inflammation, we have used a highly tractable CCl4-induced model of reversible hepatic fibrosis to identify and characterize the macrophage phenotype responsible for tissue remodeling: the hitherto elusive restorative macrophage.

We observed a marked enrichment (ﬁve- to six-fold) in Ly6C+Ly6G+ granulocytes and a modest accumulation of Ly6C+Ly6G- monocytes and F4/80+ macrophages in the premetastatic lungs of 4T1 tumor-bearing mice (Fig. 1D Neutrophils (R1, Gr‐1 high F4/80 neg cells) express Ly6C and Ly6G; macrophages (R2, Gr‐1 int F4/80 + cells) express Ly6C but not Ly6G. Dotted line: Isotype control antibody. Solid line: Anti‐Ly6C or anti‐Ly6G mAb. Effect of in vivo administration of 1A8 or RB6‐8C5 on blood leukocyte populations. The presence of macrophages in the lung interstitium has long been accepted, but how to distinguish them from other mononuclear phagocytes and where they are located is unclear.
