Nov 20, 2014 Ly6G - a marker for monocytes, granulocytes and neutrophils Ly6G ( Lymphocyte antigen 6 complex locus G6D) is a 21-25kD

CD11b+Gr1+ myeloid derived suppressor cells (MDSC) are known to be very potent suppressors of T cell immunity and can be further stratified into granulocytic MDSC and monocytic MDSC in mice based on expression of Ly6G or Ly6C, respectively. Here, using these markers and functional assays, we aimed t …

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). In general, G-MDSCs are classified as CD11b + Ly6G + Ly6C +, whereas M-MDSCs are CD11b + Ly6G − Ly6C +, although there is some variability in the degrees to which these markers are expressed (1, 8, 14, 16, 17). The Ly6C (or Gr‐1) Hi subset has been termed “classical” or “inflammatory” while Ly6C (or Gr‐1) Low‐neg cells are termed “nonclassical” or “resident” (2, 3). Both of these subpopulations express the 125 kDa transmembrane adhesion glycoprotein F4/80, (4) which is not essential for macrophage function (5).

In this review, we will provide an overview of the Ly6 complex and discuss, in detail, the speciﬁc Ly6 proteins implicated in neutrophil biology. J. Leukoc. The RB6-8C5 monoclonal antibody reacts strongly with mouse Ly6G and weakly with mouse Ly6C previously referred to as GR-1. Ly6G is a 21-25 kDa member of the Ly-6 superfamily of GPI-anchored cell surface proteins with roles in cell signaling and cell adhesion. Ly6G is expressed differentially during development by cells in the myeloid lineage including monocytes macrophages granulocytes and (H) Ly6G+ cells (magenta) are polymorphonuclear, consistent with neutrophils, whereas Ly6C+ cells (white) appear mononuclear, consistent with monocytes. Scale bars: 20 mum. (I) Compared with untreated eyes, a statistically significant elevation in the number of neutrophils (CD45+CD11b+Ly6G+) can be seen during EIU and is proposed as a single measure score.

About InVivo MAb anti-mouse Ly6G/Ly6C (Gr-1) The RB6-8C5 monoclonal antibody reacts strongly with mouse Ly6G and weakly with mouse Ly6C previously referred to as GR-1.

NASH-HCC. Ly6C.

Ly6G was identified as a novel member of the Ly6 family in 1993 [58, 68]. Ly6G is a small protein of 25 kD that is tethered to the cell membrane via a GPI linker . Unlike the Gr‐1 antigen, which encompasses epitopes from Ly6G and Ly6C, expression of Ly6G is markedly restricted.

The slides were mounted using Pro-Long Gold mounting media (Invitrogen, Oregon, USA) and inspected in a Zeiss microscope and analyzed with Volocity software. Western blot Spleen cells were stained as described above and Ly6C+G+, 2012-12-12 · The CD11b + Ly6C ++ Ly6G-population had expanded extensively in the spleen of granuloma-carrying mice. In contrast, mainly the CD11b + Ly6C + G + population, and to a lower extent the CD11b + Ly6C ++ Ly6G-population, expanded in spleen of mice with experimental autoimmune encephalomyelitis (EAE). 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. So panel should include CD11b, CD115, Ly6c, Ly6g (or use SSC with high voltage). Can also include CD45 as you want to gate for the CD45+ population.

(I) Compared with untreated eyes, a statistically significant elevation in the number of neutrophils (CD45+CD11b+Ly6G+) can be seen during EIU and is proposed as a single measure score. Monocytes typically express Ly6G transiently during development while mature granulocytes and peripheral neutrophils retain expression making Ly6G a good cell surface marker for these populations.

S100A9, Arginase 1 and iNOS gene expression in the various CD11b + cell populations was analyzed using Q-PCR. The suppressive activity of the CD11b + cell populations from different donors was studied in co-culture experiments. Circulating monocytes can be divided into two populations: Ly6c+ monocytes and Ly6c− monocytes.

RB6-8C5 binds to 2 members of the Ly6 family of leukocyte-expressed markers, Ly6C and Ly6G. We observed that MPA promoted the accumulation of NK cells in spleens of tumor-bearing mice, but with reduced degranulation ability and in vivo cytotoxic activity.

Product Specific Information Description: The RB6-8C5 monoclonal antibody reacts with mouse Ly-6G, a 21-25 kDa protein also known as the myeloid differentiation antigen Gr-1. A GPI-linked protein, Gr-1 is expressed by the myeloid lineage in a developmentally regulated manner in the bone marrow. The Ly6C (or Gr‐1) Hi subset has been termed “classical” or “inflammatory” while Ly6C (or Gr‐1) Low‐neg cells are termed “nonclassical” or “resident” (2, 3). Both of these subpopulations express the 125 kDa transmembrane adhesion glycoprotein F4/80, (4) which is not essential for macrophage function (5).

Ly6G was identified as a novel member of the Ly6 family in 1993 [58, 68]. Ly6G is a small protein of 25 kD that is tethered to the cell membrane via a GPI linker .

Anti‐Gr‐1 antibody (Ab) administration depletes both Ly6C − Ly6G + cells and Ly6C + Ly6G − cells, whereas anti‐Ly6G Ab specifically depletes Ly6C − Ly6G + cells from the peripheral blood To determine the specific roles of each fraction in lesion areas after SCI, we developed myeloid cell depletion models using neutralizing Abs.

Ly6C is a monocyte/macrophage and endothelial cell differentiation antigen regulated by interferon gamma and is thought to play a role in the development and maturation of lymphocytes. The NIMP-R14 antibody has been shown to be useful for depletion of neutrophils in mice.
