Measuring multiple parameters of CD8+ tumor-infiltrating lymphocytes in human cancers by image analysis
BACKGROUND Immuno-oncology and cancer immunotherapies are areas of intense research. The numbers and locations of CD8+ tumor-infiltrating lymphocytes (TILs) are important measures of the immune response to cancer with prognostic, pharmacodynamic, and predictive potential. We describe the development, validation, and application of advanced image analysis methods to characterize multiple immunoh...
متن کاملCD8+ T lymphocytes infiltrating breast cancer
Lymphocytic infiltration is often seen in breast cancer and has been suggested as a marker of host anti-tumor response but its importance in prognosis remains controversial. Our recent study demonstrated an association between tumor-infiltrating CD8(+) T lymphocytes in invasive breast cancer and better prognosis.
متن کاملHLA-E-restricted recognition of cytomegalovirus-derived peptides by human CD8+ cytolytic T lymphocytes.
HLA-E-restricted T cell receptor alphabeta+ CD8+ cytolytic T lymphocytes (CTLs) exist as monoclonal expansions in the peripheral blood of some individuals. Here, we show that they recognize, with high avidity, peptides derived from the UL40 protein of different human cytomegalovirus (CMV) strains. Recognition results in the induction of cytotoxicity, IFN-gamma production and cell proliferation....
متن کاملPD-L1 expression and tumor-infiltrating lymphocytes
Upon analysis of 636 primary breast carcinoma patient samples, we have found that programmed cell death ligand 1 (PD-L1) mRNA expression is associated with tumor-infiltrating lymphocytes (TILs). Furthermore, PD-L1 expression and elevated TILs were associated with longer recurrence-free survival. Thus, our findings indicate that PD-L1 is prognostic in breast cancer and suggests a functional link...
متن کاملCandida albicans Structural and Secreted Proteins Modulate CD4/CD8 Ratio in Tumor Infiltrating Lymphocytes of Spontaneous Adenocarcinoma Bearing Mice
Background: Candida albicans is one of the most important opportunistic pathogens that suppress immunologic mechanisms of the host. It is speculated that structural and secretory proteins of C. albicans have immunomodulatory effects in cancer. Objective: To evaluate the effects of C. albicans structural and secreted proteins on intratumoral CD4/CD8 ratio as well as the survival rate in BALB/c t...
