In infected individuals, HIV mutates rapidly to escape recognition by immune cells. This process of continuous evolution is the main obstacle to natural immunity and the development of an effective vaccine. A new study published by Cell Press in the March 21 issue of the journal Immunity reveals that the immune system has the capacity to adapt such that it can recognize mutations in HIV. The findings suggest that our immune cells' adaptability could be harnessed to help in the fight against AIDS. http://medicalxpress.com/news/2013-03-harnessing-immune-cells-effective-hiv.html Immunology Thu, 21 Mar 2013 12:38:36 EST news283088296 (Medical Xpress)—Eating your greens may be even more important that previously thought, with the discovery that an immune cell population essential for intestinal health could be controlled by leafy greens in your diet. http://medicalxpress.com/news/2013-03-gene-discovery-reveals-importance-greens.html Immunology Mon, 04 Mar 2013 07:25:10 EST news281604297 A compound that stimulates the production of a tumor-fighting protein may improve the usefulness of the protein in cancer therapy, according to a team of researchers. http://medicalxpress.com/news/2013-02-compound-tumor-fighting-protein-cancer-therapy.html Cancer Wed, 06 Feb 2013 15:19:06 EST news279386339 (Medical Xpress)—A first-of-its-kind vaccine developed by University of Pittsburgh Cancer Institute (UPCI) researchers successfully prompted the immune system to respond to early indications of colon cancer in people at high risk for the disease. http://medicalxpress.com/news/2013-01-vaccine-triggers-immunity-colon-cancer.html Cancer Tue, 08 Jan 2013 08:12:09 EST news276855120 Blood-circulating immune cells can take over the essential immune surveillance of the brain, this is shown by scientists of the German Center for Neurodegenerative Diseases and the Hertie Institute for Clinical Brain Research in Tübingen. Their study, now published in PNAS, might indicate new ways of dealing with diseases of the nervous system. http://medicalxpress.com/news/2012-10-immune-cells-blood-dysfunctional-brain.html Medical research Mon, 22 Oct 2012 10:40:01 EST news270119780 Dendritic cells, discovered in 1973 by Ralph Steinman (2011 Nobel prize in Physiology or Medicine) and known for their role as sentinels of the immune system, have an essential function in the development of high endothelial venules (HEVs), acting as genuine entry sites of lymphocytes into lymph nodes, inflamed tissues and malignant tumors. This is what Christine Moussion and Jean-Philippe Girard, researchers at the Institut de Pharmacologie et de Biologie Structurale (CNRS/France) showed in a study published online in the journal Nature on November 13, 2011. A better understanding of this process could lead to major applications in the treatment of chronic inflammatory diseases and cancer. http://medicalxpress.com/news/2011-11-dendritic-cells-lymphocyte-entry-lymph.html Medical research Thu, 17 Nov 2011 08:28:06 EST news240740873
