    No Oxygen? No Glucose? No Problem: Fatty Acid Catabolism Enhances Effector CD8(+) TILs.
    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 CD8(+) TILs 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 CD8(+) T 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 CD8(+) TILs 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 CD8(+) TILs' effector functions, although co-inhibitor expression increases during tumor progression regardless of CD8(+) TILs' antigen specificity.

    Immune infiltrates in the breast cancer microenvironment: detection, characterization and clinical implication.
    Breast Cancer 2017 Jan 2;24(1):3-15. Epub 2016 May 2.

    Although unlike melanoma, breast cancer is not generally viewed as a highly immunogenic cancer, recent studies have described a rich tumor immune microenvironment in a subset of breast cancers. These immune infiltrates, comprised cells from the innate and adaptive immune response, can be detected and characterized in biopsy specimens and have prognostic value. Tumor-infiltrating lymphocytes (TILs) represent the majority of mononuclear immune infiltrates in the breast tumor microenvironment and can be easily identified in formalin-fixed paraffin-embedded tissues after standard hematoxylin and eosin staining.

    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.
    Division of Thoracic Surgery, Department of Thoracic Surgery, Medical University of Vienna, Waehringer Guertel 18-20, 1090, Vienna, Austria.
    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
    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
