Tumor-Associated T Cells Ability to Modulate the Activation of Tumor-Associated Fibroblasts and Their Characterization of Human Lung

Whole Tumor Cell Vaccine Adjuvants: Comparing IL-12 to IL-2 and IL-15

Cancer immunotherapy (passive or active) involves treatments which promote the ability of the immune system to fight tumor cells. Several types of immunotherapeutic agents, such as monoclonal antibodies, immune checkpoint inhibitors, non-specific immunomodulatory agents, and cancer vaccines are currently under intensive investigation in preclinical and clinical trials. Cancer vaccines induce pe...

Immunohistochemical evaluation of lymphocyte types infiltrate into the canine seminomas

BACKGROUNDS: Seminoma is frequently observed in human and canine testes especially in cryptorchids. Canine and human seminomas are typically associated with leukocytic infiltration. OBJECTIVES: We aimed to identify the type of lymphocytes that infiltrate to seminomas. METHODS: Tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. Routine...

Tumor Associated Mesenchymal Stromal Cells Show Higher Immunosuppressive and Angiogenic Properties Compared to Adipose Derived MSCs

Background: Differentiation, migratory properties and availability of Mesenchymal Stromal Cells (MSC) have become an important part of biomedical research. However, the functional heterogeneity of cells derived from different tissues has hampered providing definitive phenotypic markers for these cells. Objective: To characterize and compare the phenotype and cytokines of adipose derived MSCs (...

Reciprocal functional modulation of the activation of T lymphocytes and fibroblasts derived from human solid tumors.

Fibroblasts are a dominant cell type in most human solid tumors. The possibility that fibroblasts have the capacity to interact with and modulate the function of tumor-associated T lymphocytes makes them a potential therapeutic target. To address this question, primary cultures of fibroblasts derived from human lung tumors were established and cultured with T cells derived from the same tumor. ...
