Modifying tumor-associated macrophages
The therapeutic success of immunotherapy requires specific alterations of the tumor microenvironment and/or the inhibition of tumor-elicited immunosuppression. Tumor-associated macrophages (TAMs) are a major component of the tumor microenvironment. We have recently shown that modulating TAMs dramatically augments the efficacy of immunotherapy. TAM-activating agents should hence be considered as...
متن کاملP157: Periostin Recruits Tumor Associated Macrophages in Glioblastoma Multiform
Glioblastoma multiform (GBM) is the most common and lethal type of primary brain tumors with high rates of morbidity and mortality. Treatment options are limited and ineffective in most of the cases. Epidemiological studies have shown a link between inflammation and glioma genesis. In addition, at the molecular level, pro-inflammatory cytokines released from activated microglia can increa...
متن کاملFlowcytometric Analysis of Tumor Associated Macrophages in Invasive Ductal Carcinoma of Breast
Background: Invasive ductal carcinoma is the most common type of breast cancer in Iran. Impaired immune responses occur frequently in cancer patients, but the mechanisms of the induced immune defects remain poorly understood. It is believed that infiltrated immune cells, especially macrophages, may provide help for tumor cell growth and metastasis. Objective: To analyze the status of tumor as...
متن کاملHypoxia and tumor-associated macrophages
Tumor-associated macrophages (TAMs) provide a significant contribution to tumor growth and metastasis. We demonstrated the existence of two main TAM subsets, differing in activation state and localization. Of these, M2-like TAMs reside in hypoxic regions of the tumor mass and can be used as targets for hypoxia tracers. This said, hypoxia does not regulate the differentiation of TAMs but finely ...
متن کاملMacrophages in malignant pleural effusions – alternatively activated tumor associated macrophages
Pleural macrophages are involved in local defense mechanisms against environmental pollution, bacteria and cancer. Their main function encompasses phagocytosis of degenerated mesothelial cells. In human pleural effusions macrophages represent more than half of all cells. A model of polarized macrophage activation (M1 and M2) was proposed, which defines a functionally different macrophage popula...
