Infectious disease specialists at UT Southwestern Medical Center have mapped the gene profiles of children with severe Staphylococcus aureus infections, providing crucial insight into how the human immune system is programmed to respond to this pathogen and opening new doors for improved therapeutic interventions. http://www.physorg.com/news166771679.html Medicine & Health Tue, 14 Jul 2009 06:29:02 EST news166771679 Transplant patients rely on drugs to prevent graft rejection, but at the cost of serious side effects. The class of immunosuppressive drugs known as calcineurin inhibitors (examples are cyclosporine and tacrolimus) can damage patients' kidneys and lead to high blood pressure, among other problems. http://www.physorg.com/news166276476.html Medicine & Health Wed, 08 Jul 2009 12:54:56 EST news166276476 Rapamycin, a drug given to transplant recipients to suppress their immune systems, has a paradoxical effect on cells responsible for immune memory, scientists at the Emory Vaccine Center have discovered. http://www.physorg.com/news164809846.html Medicine & Health Sun, 21 Jun 2009 13:31:30 EST news164809846 May 28, 2009 - Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins. http://www.physorg.com/news162708029.html Medicine & Health Thu, 28 May 2009 05:41:59 EST news162708029 New research published today (Monday April 27) from the University of Leicester and University Hospitals of Leicester NHS Trust warns of a six-month time lag before effective vaccines can be manufactured in the event of a pandemic flu outbreak. http://www.physorg.com/news160071628.html Medicine & Health Mon, 27 Apr 2009 17:20:55 EST news160071628 When an infection attacks, the body's immune system sounds the alert, kills the invading germs and remembers the pathogen to protect against contracting the same type of infection again. Exactly how immunological memory develops is a mystery just beginning to be unveiled by Emma Teixeiro, PhD, in an article published in the Jan. 23 issue of the journal Science. http://www.physorg.com/news151858322.html Medicine & Health Thu, 22 Jan 2009 14:52:30 EST news151858322 Scientists at UT Southwestern Medical Center have determined that the immune-system protein interferon plays a key role in "teaching" the immune system how to fight off repeated infections of the same virus. http://www.physorg.com/news147506941.html Medicine & Health Wed, 03 Dec 2008 06:09:01 EST news147506941
