Dynamic differentiation of F4/80+ tumor-associated macrophage …
Feb 13, 2023 · The metastatic Mc38 cells made full use of liver vessels and perivascular TAMs; they further adopted VM vessels to match the rapid growth of tumor vasculature.
Radiation combined with macrophage depletion promotes …
CD11b + F480 + TAMs were isolated from MC38 (H) and KPC (I) tumours 5 days following irradiation (±aCSF), and expression of selected immune stimulatory and immunosuppressive genes was analysed by RT–qPCR (n = 3).
Dynamic differentiation of F4/80+ tumor-associated macrophage …
Feb 13, 2023 · Tumor-associated macrophages (TAMs) are highly heterogeneous and play vital roles in tumor progression. Here we adopted a C57BL/6 mouse model imitating the late-stage colorectal liver metastasis (CRLM) by Mc38 colorectal cancer cell injection via the portal vein.
Arg1 expression defines immunosuppressive subsets of tumor …
Here we chose to dissect the function of immunosuppressive Arg1+ TAM in an immunotherapy-responsive MC38 mouse tumor model during aPD-1 treatment. We used the syngeneic MC38 tumor model given its widespread use in immune-oncology and high macrophage content 10.
Reprogramming Tumor-Associated Macrophages by Antibody …
May 31, 2016 · To investigate whether it was expressed in tumor stroma of mice, we investigated mammary carcinoma (4T1) injected in mammary fat pads as well as in melanoma (B16) and colon carcinoma (MC38) growing subcutaneously (s.c.).
Obesity induces PD-1 on macrophages to suppress anti-tumour
Jun 7, 2024 · Diet-induced obesity (DIO) can alter the tumour immune landscape 24. A syngeneic subcutaneous tumour model using a colorectal adenocarcinoma cell line, MC38, was initially used to test the...
Optimized antiangiogenic reprogramming of the tumor ... - PNAS
Dec 30, 2019 · We observed that anti-CD40 either alone or in combination with anti-VEGFA/Ang2 markedly reduced the frequency of CD11b + Ly6C − Ly6G – F480 + macrophages (TAMs) in the leukocyte infiltrate of MC38 tumors (Fig. 3 A).
Dynamic differentiation of F4/80+ tumor-associated
Feb 1, 2023 · F4/80+ TAMs showed proximity to neovascularization and tumor vessels, functionally angiogenic in vivo; and greatly promoted the activation of a few key angiogenic markers such as VEGFA, Ki67,...
Baseline Frequency of Inflammatory Cxcl9-Expressing Tumor-Associated ...
Jul 7, 2020 · We identify a proinflammatory F480 + MHCII + Ly6C lo macrophage population that is associated with response rather than resistance to avelumab. These macrophages are the primary source of the interferon-inducible chemokine Cxcl9, which facilitates the recruitment of protective Cxcr3+ T cells.
Dynamic differentiation of F4/80+ tumor-associated macrophage …
In our syngeneic mouse CRLM model, survived Mc38 cells in the liver may in time create a tumor microenvironment that favored Kupffer cells to proliferate in situ and/or myeloid monocyte/macrophages to infiltrate, both differentiated into tumor-promoting F4/80 + TAMs.
