Homeostatic proliferation as an isolated variable reverses CD8+ T cell anergy and promotes tumor rejection.
Although recent work has suggested that lymphopenia-induced homeostatic proliferation may improve T cell-mediated tumor rejection, there is little direct evidence isolating homeostatic proliferation as an experimental variable, and the mechanism by which improved antitumor immunity occurs via homeostatic proliferation is poorly understood. An adoptive transfer model was developed in which tumor...
متن کاملHomeostatic proliferation plus regulatory T-cell depletion promotes potent rejection of B16 melanoma.
PURPOSE To investigate the antitumor efficacy of T-cell anergy reversal through homeostatic proliferation and regulatory T-cell (Treg) depletion in a clinically relevant murine adoptive immunotherapy model. EXPERIMENTAL DESIGN B16 melanoma cells were engineered to express the model SIYRYYGL (SIY) antigen to enable immune monitoring. Tumor-specific T cells expanded in tumor-challenged wild-typ...
متن کاملCombination OX40 agonism/CTLA-4 blockade with HER2 vaccination reverses T cell anergy and promotes survival in tumor-bearing mice
Immunotherapy is gathering momentum as a primary therapy for cancer patients. However, monotherapies have limited efficacy in improving outcomes and benefit only a subset of patients. Combination therapies targeting multiple pathways can augment an immune response to improve survival further. Here, we demonstrate that dual aOX40 (anti-CD134)/aCTLA-4 (anti-cytotoxic T-lymphocyte-associated prote...
متن کاملLncRNA Miat Promotes Proliferation of Cervical Cancer Cells and Acts as an Anti-apoptotic Factor
There are a sub-population of cells in tumor tissues known as cancer stem cells (CSCs) which have similar features with stem cells, including self-renewal and differentiation capacity. Recently, it was established that not only stem cells factors such as Oct4, but also ES-associated lncRNAs are contributing to various regulatory aspects of CSCs. Myocardial infarction associated transcript (MIAT...
متن کاملHomeostatic T Cell Proliferation
Through positive and negative selection, the thymus allows a small fraction of immature CD4 ϩ 8 ϩ double positive thymocytes to differentiate into mature CD4 ϩ 8 Ϫ or CD4 Ϫ 8 ϩ single positive cells; these cells are released into the periphery to establish the mature T cell pool. Positive selection rescues thymocytes that express TCR with low affinity for peptides bound to MHC molecules express...
