A new study provides evidence that a critical type of immune cell can develop in human tonsils. The cells, called T lymphocytes, or T cells, have been thought to develop only in the thymus, an organ of the immune system that sits on the heart. The study, led by researchers at the Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC — James), could improve the understanding of T-cell cancers and...

Study in Nature Medicine could lead to novel therapy for cancer In a study published in Nature Medicine, Loyola researchers report on a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer. The technique involves delivering DNA into the immune system's instructor cells. The DNA directs these cells to overproduce a specific protein that jumpstarts important killer T cells. These killer cells...

A scientific team led by researchers at the University of Geneva (UNIGE) and the Charité Berlin Medical University has made a completely unprecedented discovery showing how much our immune system is provoked into action when confronted by viral intruders. The possibility of exploiting this mechanism in vaccines holds promise for the development of new ways of preventing and treating infectious diseases and cancer. Killer T cells — also called cytotoxic T lymphocytes...

Immunological diseases, such as eczema and asthma, are on the increase in westernised society and represent a major challenge for 21st century medicine. A new study has shown, for the first time, that growing up on a farm directly affects the regulation of the immune system and causes a reduction in the immunological responses to food proteins. The research, led by the University of Bristol's School of Veterinary Sciences, found that spending early life in a complex farm environment...

(Ivanhoe Newswire) -- T lymphocytes (T Cells) are supposed to be screened for their ability to recognize normal tissue during development. These auto-reactive cells are normally removed, but some slip by safeguards and could contribute to autoimmune disease. According to Kai Wucherpfennig at the Dana-Farber Cancer Institute and Harvard Medical School, auto-reactive T cells from patients with type 1 diabetes and multiple sclerosis bound their targets more weakly than helpful T cells that...

Susceptibility to anthrax toxin is a heritable genetic trait that may vary tremendously among individuals, according to a new study by researchers at the Stanford University School of Medicine. Among 234 people studied, the cells of three people were virtually insensitive to the toxin, while the cells of some people were hundreds of times more sensitive than those of others. The findings may have important implications for national security, as people known to be more resistant to anthrax...

Leukemic cutaneous T-cell lymphoma (L-CTCL) is a leukemia arising from T-cells, a type of white blood cell. This cancer can involve the skin and other organs, and patients often die within three years. Rachael A. Clark, MD, PhD, BWH assistant professor of dermatology and associate dermatologist and Thomas Kupper, MD, BWH Department of Dermatology chairman and their colleagues now report a new study that low-dose Campath (alemtuzumab) not only treats patients with L-CTCL but does so without...

These new data are an essential step towards understanding the operation of these key cells in the immune system, and they could provide a new therapeutic approach to fighting infection. They also suggest that the operation of NK cells must be precisely regulated to guarantee an optimum immune reaction. Details of this work are published in the 20 January 2012 issue of the journal Science. Our bodies are subject to attack by many different infectious particles (bacteria, viruses, etc.),...

A research team led by Glenn Rall at the Fox Chase Cancer Center in Philadelphia, PA developed a novel mouse model to show that a fatal central nervous system (CNS) disease can be caused by a pathogen that does not replicate in the CNS. The results of this new study are published December 22nd in the Open Access journal PLoS Pathogens. The authors found that the immune response induced in response to a peripheral viral infection can be "mis-recruited" to the brain, where these activated...
