UT Southwestern Medical Center scientists report the first successful blocking of tumor development in a genetic mouse model of an incurable human cancer. http://medicalxpress.com/news/2013-03-scientists-mouse-human-cancer.html Cancer Tue, 05 Mar 2013 12:16:31 EST news281708184 (Medical Xpress)—In a pair of new papers, researchers at the University of California, San Diego School of Medicine and the Royal Netherlands Academy of Arts and Sciences upend a long-held view about the basic functioning of a key receptor molecule involved in signaling between neurons, and describe how a compound linked to Alzheimer's disease impacts that receptor and weakens synaptic connections between brain cells. http://medicalxpress.com/news/2013-02-rewriting-receptor-role-synaptic-molecule.html Alzheimer's disease & dementia Tue, 19 Feb 2013 13:44:20 EST news280503847 B cells can generate different 'classes' of antibodies, each of which carries a specific type of protein chain that triggers a specific downstream cascade of immune responses. Immunoglobulin M (IgM) antibodies, which are the first on the scene, play a particularly important role in fighting off pathogen infection. http://medicalxpress.com/news/2013-02-receptor-trigger-immune-response.html Immunology Fri, 01 Feb 2013 10:17:17 EST news278936230 Researchers at the Hebrew University of Jerusalem, in collaboration with researchers at the Salk Institute in California, have found for the first time that a specific protein is essential not only for maintaining a healthy retina in the eye, but also may have implications for understanding and possibly treating other conditions in the immune, reproductive, vascular and nervous systems, as well as in various cancers. http://medicalxpress.com/news/2013-01-specific-protein-essential-healthy-eyes.html Neuroscience Mon, 07 Jan 2013 07:53:08 EST news276767582 (Medical Xpress) -- One in five Americans suffers from autoimmune disease, in which the immune system goes off-track and attacks the body's own cells. Cornell researchers have identified a signaling mechanism in immune-system cells that may contribute to this mistake, opening the door for possible new therapies for autoimmune diseases such as lupus and arthritis. http://medicalxpress.com/news/2011-11-unchecked-alarms-autoimmune-disease.html Medical research Tue, 29 Nov 2011 03:50:02 EST news241760991 The dog may be man's best friend but even so it comes as a surprise that the two species share a common tumor marker. This finding comes from a joint study between scientists of the Vetmeduni Vienna and the MedUni Wien. The researchers uncovered a molecule, the CEA (carcinoembryonic antigen) receptor, that is almost identical in the two species. The result could lead to the rapid development of new therapies for dogs and humans. http://medicalxpress.com/news/2011-04-friend-joint-tumor-marker-dog.html Cancer Mon, 18 Apr 2011 09:36:01 EST news222338108
