Targeting DAP5 Disrupts Alternate Mode of Translational Initiation in Tregs and Potentiates Antitumor Immunity

Advanced Science, EarlyView.
Regulatory T cells (Tregs) suppress antitumor immunity. This study identifies that the translation scaffold DAP5/eIF4G2 is upregulated in tumor‐infiltrating Tregs (ti‐Tregs). DAP5 mediates an alternate translation mode to sustain CD25 and MCL‐1 expression, which is critical for ti‐Treg stability and survival in the tumor microenvironment.

Melanoma vaccines and modulation of the immune system in the clinical setting: building from new realities

Frontiers in Immunology, 2012
To endow the immune system with the capacity to fight cancer has always attracted attention, although the clinical results obtained have been until recently disappointing.

Polymorphism analysis of the CTLA-4 (rs231775) gene as a marker of inhibitor development in Iranian patients with hemophilia A [PDF]

, 2018
Background: Development of factor VIII (FVIII) inhibitor is the main problem of replacement therapy in patients with hemophilia A. Recently, the correlation of polymorphisms of some genes involved in immune system has been determined with inhibitor ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Lack of Association between Promoter Gene Polymorphism (-318 C/T) and Multiple [PDF]

Journal of Sciences, Islamic Republic of Iran, 2008
Multiple sclerosis (MS), a chronic inflammatory demyelinating disease of the central nervous system is believed to have a T cell-mediated autoimmune etiology. The cytotoxic T lymphocyte antigen 4 (CTLA-4) gene is a strong candidate for the involvement in

Integrating Spatial Proteogenomics in Cancer Research

Advanced Science, EarlyView.
Xx xx. ABSTRACT Background: Spatial proteogenomics marks a paradigm shift in oncology by integrating molecular analysis with spatial information from both spatial proteomics and other data modalities (e.g., spatial transcriptomics), thereby unveiling tumor heterogeneity and dynamic changes in the microenvironment.

CTLA-4 expression on antigen-specific cells but not IL-10 secretion is required for oral tolerance

European Journal of Immunology, 2002
CD4(+) T cells play a vital role in mediating the tolerance induced at mucosal sites following exposure to non-pathogenic stimuli, and further understanding of the precise mechanisms by which these cells prevent aberrant responses is required. We have developed a model using transfer of DO11.10 TCR-transgenic bone marrow into irradiated recipients in ...

Targeting the Mapk13‐Tcf1‐Slc7a5 Axis via One‐Carbon Metabolic Regulation to Prevent Chronic Allograft Vasculopathy

Advanced Science, EarlyView.
This study emphasizes the role of the Mapk13‐Tcf1‐Slc7a5‐methionine metabolism axis in stem‐like CD4+ T cells. Moreover, it uncovers the mechanism through which limiting one‐carbon metabolism in CD4+ stem‐like T cells suppresses the tide of chronic allograft vasculopathy, offering potential targets to promote long‐term graft survival.
