Tc17 biology and function: Novel concepts
2020
Research over the past years has provided increasing understanding about IL-17-producing CD8+ T cells termed Tc17 or IL-17+ CD8+ T cells, their distribution and role in a range of diverse immune processes. These comprise resistance to pathogens and tissue homeostasis, but also contribution to autoimmunity and cancer, as well as involvement in gut inflammation, lung diseases and graft-versus-host-disease. Tc17 cells are regulated by unique differentiation mechanisms distinguishing them from other IL-17-producing T cells, including Th17, mucosal-associated invariant T cells, and γδ17 T cells, thus ensuring their specific function in immune responses. Here, we review recent advances in underst…
Microenvironmental Th9 and Th17 lymphocytes induce metastatic spreading in lung cancer.
2020
Immune microenvironment plays a critical role in lung cancer control versus progression and metastasis. In this investigation, we explored the effect of tumor-infiltrating lymphocyte subpopulations on lung cancer biology by studying in vitro cocultures, in vivo mouse models, and human lung cancer tissue. Lymphocyte conditioned media (CM) induced epithelial-mesenchymal transition (EMT) and migration in both primary human lung cancer cells and cell lines. Correspondingly, major accumulation of Th9 and Th17 cells was detected in human lung cancer tissue and correlated with poor survival. Coculturing lung cancer cells with Th9/Th17 cells or exposing them to the respective CM induced EMT in canc…
