UCF researchers have made a groundbreaking discovery on immune cells, focusing on transfer RNA (tRNA) as a pathway to treatments for cancers, infections, and autoimmune disorders. By modifying tRNA in T cells, the team aims to fine-tune immune responses to multiple diseases.
A study by Van Andel Institute scientists found that reducing calorie intake helps cancer-fighting immune cells do their jobs more effectively. The researchers discovered that a low-fat, high-protein diet given once a day promotes the formation of ketones, which act as a cellular fuel for T cells to become more effective tumor fighters.
A recent study published in Nature Communications provides a comprehensive characterization of Large Cell Neuroendocrine Carcinoma (LCNEC), a rare and aggressive type of lung cancer. The research team analyzed data from 590 patients and found that LCNEC shares features with other types of lung cancer, yet has distinct aspects. They ide...
Researchers at University of Alabama at Birmingham identify Gfi1 as a crucial regulator of exhausted CD8+ T cell subsets. Fine-tuning Gfi1 activity may prevent or reverse T cell exhaustion, bolstering immune checkpoint blockade therapy. The study suggests potential for improving cancer treatment and controlling chronic infections.
The Damon Runyon Cancer Research Foundation has awarded $4.2 million to five new Clinical Investigators conducting patient-oriented cancer research. The awards will support the development of new treatments for cancer patients, with a focus on enhancing efficacy and safety.
Researchers found that neoself-antigens, presented on MHC-II, induce an immune response and lead to autoimmunity in lupus patients. EBV reactivation increases the presentation of these antigens, triggering T cell activation and autoimmune disease development.
Researchers from Tokyo Medical and Dental University have identified PD-1+ T cells as the culprit behind harmful inflammation in certain muscular disorders. The study found that these cells, when activated, produce cell-damaging molecules, causing body-wide weakness and pain.
A University of Ottawa-led research team has made significant progress in understanding XLP-2, a genetic disorder that affects the immune system. The study reveals two underlying mechanisms: poor expression of Interleukin-6 and compromised T cell survival, which lead to immunodeficiency in patients.
Scientists found that CXCL13-mediated recruitment of B cells helps predict response to immunotherapy treatment. This cooperation between T cells and B cells is associated with improved survival in patients treated with immunotherapy.
A recent study by La Jolla Institute for Immunology researchers has identified new subsets of CD4+ 'helper' T cells that are linked to autoimmune disease risk. The team used single-cell RNA sequencing to compare gene expression in over 1 million CD4+ T cells from 89 healthy donors, revealing sex-based differences in immune cell functio...
Researchers mapped how HTLV-1 transforms T-cells into cancerous cells, revealing the virus over-activates them and makes them more vulnerable to DNA damage. This study provides new directions for potential treatments to prevent cancer development.
Scientists at Stanford University School of Medicine have invented a litmus test for the effectiveness of a newly devised cancer therapy using a radioactive tracer that tracks activated immune cells. The tracer's capabilities also make it a powerful tool to detect autoimmune diseases.
Salk Institute researchers have visualized the natural arrangements of vital receptors on T cell surfaces in lymph nodes, revealing pre-organized 'territories'. This study could help scientists better understand how to modulate the immune system's activity for autoimmune diseases or cancer treatments.
Research finds gut microbes produce a molecule mimicking retinal protein, activating T cells responsible for autoimmune uveitis. The study offers a novel mechanism explaining how tissue-specific autoimmune diseases can arise from responses to gut microbes at a distal site in the body.
Researchers discovered HIV can replicate in resting T cells, previously thought to be uninfected. The virus spreads quickly through activated T cells as well, but these infected cells are harder to reach with current therapies.
