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. Read More

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.

Pathology and Laboratory Medicine, Anatomical Pathology JPN 1401, University of British Columbia, 855 W. 12th Avenue, Vancouver, BC, V5Z 1M9, Canada.

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

Characterization of tumor-associated T-lymphocyte subsets and immune checkpoint molecules in head and neck squamous cell carcinoma.

Oncotarget 2017 07;8(27):44418-44433

Department of Otorhinolaryngology, Head and Neck Surgery, University of Cologne, Cologne, Germany.

The composition of tumor-infiltrating lymphocytes (TIL) reflects biology and immunogenicity of cancer. Here, we characterize T-cell subsets and expression of immune checkpoint molecules in head and neck squamous cell carcinoma (HNSCC). We analyzed TIL subsets in primary tumors (n = 34), blood (peripheral blood mononuclear cells (PBMC); n = 34) and non-cancerous mucosa (n = 7) of 34 treatment-naïve HNSCC patients and PBMC of 15 healthy controls.
