Methods: CD11b(+)Ly6C(++) and Ly6G(+) cells were isolated from spleen, tumor tissue or inflammatory granulomas. 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.

B) Percentage of CD11b + Gr1 + cells of total CD45 + cells isolated from murine livers following Hx or sham laparotomy, as determined by flow cytometry on indicated PODs. C) Representative plots from d 2 of data presented in B. D) Fold change (shown as log2) of the percentage of Ly6G + or Ly6C + of CD11b + cells in murine livers of Hx vs. sham.

Samples were stained concurrently with two different cocktails. The first cocktail contained CD11b, Ly6C, Ly6G, CD11c, and F4/80 (Fig. 3a) while the second cocktail contained CD11b, Ly6C, Ly6G, CD11c, and NK1.1 (Fig. 3b). After gating out debris, doublets, and nonviable cells, four sub‐populations of CD11b + cells were sorted. Purified CD11b + Ly6C hi Ly6G − and CD11b + Ly6C int Ly6G + cells were seeded into 24-well tissue culture plates at 1 × 10 5 cells per well using medium formulated for the ex vivo culture of bone marrow-derived macrophages (Dulbecco's modified Eagle medium [DMEM] with GlutaMAX-I [Invitrogen] supplemented with 20% heat-inactivated fetal bovine serum [Atlanta Biologicals], 20% L-cell 2020-06-19 · In the myeloid gate (CD11b + CD172a +), neutrophils are Ly6G +, eosinophils are Siglec F +, monocytes are Siglec F − Ly6G − CD115 + and form a continuum from Ly6C hi to Ly6C lo.

Composition of total CD11b + cells, Ly6G + Ly6C lo granulocytic cells, and Ly6C hi monocytic cells in spleen (A) and bone marrow (B) of non-tumor-bearing mice with and without 8 d of ranitidine treatment. (C) Representative flow cytometry data showing percentages of Ly6G + Ly6C lo and Ly6C hi in CD11b + splenocytes. 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 2016-11-11 · CD11b+Ly6G+ cells that had been immunosuppressive myeloid cells. 25 Administration of ligands for TLR3 or TLR9 induces a functional conversion of CD11b + Gr1 + MDSCs or CD11b + Ly6G − Ly6C Expression of uNK and CD11b + Ly6G hi Ly6C lo and CD11b + Ly6G lo Ly6C hi cell populations were analyzed using a flow cytometer. GMCSF treatment resulted in no significant change in the NK1.1 - DX5 - DBA + cell population from the CBA mice (p = 0.1164). However, an increase of the CD11b + Ly6G lo Ly6C hi population was observed (p = 0.0592).

The suppressive activity of the CD11b + cell populations from different donors was studied in co-culture experiments. 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. The CD11b + /Ly6C med /Ly6G + myeloid cells represent the granulocytic subset of a heterogeneous class of myeloid cells termed myeloid-derived suppressor cells (MDSCs; ref.

Based on the different cell surface markers, MDSCs can be classified into granulocytic MDSCs (G-MDSCs and CD11b + Ly6G + Ly6C low) and monocytic MDSCs (M-MDSCs and CD11b + Ly6G-Ly6C high) (1, 2). MDSCs are components of tumor microenvironment (TME) and support tumor progression, invasion, and metastases ( 3 , 4 ).

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.

These two subpopulations may have different functions in … Although Ly6C med−high monocytes constitute roughly 3~10-fold less numerous than circulating neutrophils during the initial 3~5 days after CVB3 infection, CD11b + Ly6G − Ly6C high/med monocyte and macrophage lineages comprise the major population of cardiac infiltrates in the later phase of CVB3 myocarditis (Fairweather et al., 2005; Huber, 2016).

(B) CD11b + Ly6G − myeloid cells can be separated into three populations based on Ly6C expression, with Ly6C low myeloid cells constituting the bulk of these cells in the naïve animal. CD11b + Ly6G − Ly6C low cells show a biphasic response after CFA injection, peaking at 24 h and again at 14 d, whereas they make up the majority of cells between 3 and 10 d after plantar incision.

However, an increase of the CD11b + Ly6G lo Ly6C hi population was observed (p = 0.0592). CD11b(+)Ly6C(++) and Ly6G(+) cells were isolated from spleen, tumor tissue or inflammatory granulomas. 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. The myeloid differentiation antigen Gr-1 consists of two epitopes, recognized by anti-lymphocyte antigen (Ly) 6G and anti-Ly6C antibodies, which divide CD11b + Gr-1 + MDSCs into Ly6G + granulocytes and Ly6C + monocytes . These two subpopulations may have different functions in infectious diseases and cancer (34–36).
