Scientists at the University of Pittsburgh School of Medicine have discovered a new biological pathway of innate immunity that ramps up inflammation and then identified agents that can block it, leading to increased survival and improved lung function in animal models of pneumonia. They reported their findings today in Nature Immunology. http://medicalxpress.com/news/2013-03-immunity-protein-ramps-inflammation-agents.html Immunology Sun, 31 Mar 2013 13:00:01 EST news283951880 Older adults who haven't been in school for a while are as capable of learning from tests as younger adults and college students, according to new research published by the American Psychological Association. http://medicalxpress.com/news/2013-03-test-taking-people-ages.html Psychology & Psychiatry Thu, 07 Mar 2013 11:31:13 EST news281878266 Research led by Minghao Jin, PhD, Assistant Professor of Ophthalmology and Neuroscience at the LSU Health Sciences Center New Orleans Neuroscience Center of Excellence, has found a protein that protects retinal photoreceptor cells from degeneration caused by light damage. This protein may provide a new therapeutic target for both an inherited retinal degenerative disease and age-related macular degeneration. The paper is published in the February 13, 2013 issue of the Journal of Neuroscience. http://medicalxpress.com/news/2013-02-protein-light-induced-retinal-degeneration.html Neuroscience Tue, 12 Feb 2013 17:00:01 EST news279910674 Patients are currently being enrolled in the first clinical trial to investigate the efficacy of immunological therapy for chronic pulmonary sarcoidosis.
