    No Oxygen? No Glucose? No Problem: Fatty Acid Catabolism Enhances Effector CD8TILs.

    Cancer Cell 2017 09;32(3):280-281
    Department of Immunobiology, Yale University School of Medicine, New Haven, CT 06520, USA. Electronic address:
    The tumor microenvironment presents metabolic constraints to immunosurveiling cells. In this issue of Cancer Cell, Zhang et al. demonstrate that CD8TILs reprogram under hypoxic and hypoglycemic conditions, regaining effector function by engaging fatty acid catabolism, which is promoted by fenofibrate and synergistic with immune checkpoint blockade therapy.

    Enhancing CD8T Cell Fatty Acid Catabolism within a Metabolically Challenging Tumor Microenvironment Increases the Efficacy of Melanoma Immunotherapy.
    Cancer Cell 2017 Sep;32(3):377-391.e9
    The Wistar Institute, Philadelphia, PA 19104, USA. Electronic address:
    How tumor-infiltrating T lymphocytes (TILs) adapt to the metabolic constrains within the tumor microenvironment (TME) and to what degree this affects their ability to combat tumor progression remain poorly understood. Using mouse melanoma models, we report that CD8TILs enhance peroxisome proliferator-activated receptor (PPAR)-α signaling and catabolism of fatty acids (FAs) when simultaneously subjected to hypoglycemia and hypoxia. This metabolic switch partially preserves CD8TILs' effector functions, although co-inhibitor expression increases during tumor progression regardless of CD8TILs' antigen specificity. Read More
    Tumor-infiltrating lymphocyte subsets and tertiary lymphoid structures in pulmonary metastases from colorectal cancer.
    Clin Exp Metastasis 2016 Oct 23;33(7):727-39. Epub 2016 Jul 23.

    The presence of tumor-infiltrating lymphocytes (TILs) and tertiary lymphoid structures (TLSs) reflects an active inflammatory tumor microenvironment. High density of TILs as well as presence of TLS is associated with improved survival in various solid cancer types. We aimed to describe the density and distribution of TILs and TLS in pulmonary metastases (PMs) from primary colorectal cancer (CRC) and its correlation with clinicopathological variables. Read More
    PD-1 Expression in Head and Neck Squamous Cell Carcinomas Derives Primarily from Functionally Anergic CD4TILs in the Presence of PD-L1TAMs.
    Cancer Res 2017 Nov 25;77(22):6365-6374. Epub 2017 Sep 25.

    Oral tongue squamous cell carcinoma (OTSCC) is the most common oral cavity tumor. In this study, we examined the basis for the activity of programmed cell death protein (PD-1)-based immune checkpoint therapy that is being explored widely in head and neck cancers. Using multispectral imaging, we systematically investigated the OTSCC tumor microenvironment (TME) by evaluating the frequency of PD-1 expression in CD8, CD4, and FoxP3tumor-infiltrating lymphocytes (TIL).

    Local administration of TLR ligands rescues the function of tumor-infiltrating CD8 T cells and enhances the antitumor effect of lentivector immunization.

    Cancer vaccines, to date, have shown limited effect to control the growth of established tumors due largely to effector failure of the antitumor immune responses. Tumor lesion is characterized as chronic indolent inflammation in which the effector function of tumor-infiltrating lymphocytes (TILs) is severely impaired. In this study, we investigated whether the effector function of CD8 TILs could be rescued by converting the chronic inflammation milieu to acute inflammation within tumors. Read More
