Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion. Yet exhausted immune cells can be revived after the introduction of fresh cells that act like coaches giving a pep talk, researchers at Emory Vaccine Center have found. Their findings provide support for an emerging strategy for treating chronic infections: infusing immune cells back into patients after a period of...

Treatment with patients' own cells may prevent infections commonly seen following treatment and prolong remission A new treatment using leukemia patients' own infection-fighting cells appears to protect them from infections and cancer recurrence following treatment with fludarabine-based chemotherapy, according to new research from the Perelman School of Medicine at the University of Pennsylvania. The new process is a step toward eliminating the harsh side effects that result from the...

New research published in the Journal of Leukocyte Biology demonstrates that elevated body temperature plays a vital role on the generation of effective T-cell mediated immune response With cold and flu season almost here, the next time you're sick, think twice before taking something for your fever. That's because scientists have found more evidence that elevated body temperature helps certain types of immune cells to work better. This research is reported in the November 2011 issue of...

Discovery could lead to new and better vaccines for Listeria, HIV and other pathogens Researchers at the La Jolla Institute for Allergy & Immunology have identified a previously unknown mechanism that generates protective immune memory cells to fight recurring infections at the body's mucosal linings — which include the mouth, the intestines, the lungs and other areas. These are the main entry points for many viruses and other infectious organisms. The findings were published...

MVA-B Spanish HIV Vaccine Shows High Immune Response In Humans
2011-09-28 04:46:39

Phase I clinical trials developed by Spanish Superior Scientific Research Council (CSIC) together with Gregorio Marañón Hospital in Madrid and Clínic Hospital in Barcelona, reveals MVA-B preventive vaccine's immune efficiency against Human's immunodeficiency virus (HIV). 90% of the volunteers who went through the tests developed an immunological response against the virus and 85% has kept this response for at least one year. Safety and efficiency of...

Scientists reveal how a type of white blood cells, called Natural Killer cells, protect the body from tumors and virus-infected cells Scientists reveal in more detail than ever before how white blood cells kill diseased tissue using deadly granules, in research published today in PLoS Biology. The researchers, from Imperial College London and the University of Oxford, used 'optical' laser tweezers and a super-resolution microscope to see the inner workings of white blood cells at the...

Bleeding calf syndrome (bovine neonatal pancytopenia or BNP) affects new born calves resulting in low blood cell counts and depletion of the bone marrow. It first emerged in 2007 and a serious number of cases are reported each year. In affected calves, bone marrow cells which produce platelets are also destroyed. Consequently the calves' blood does not clot and they appear to bleed through undamaged skin. There is evidence that BNP is linked to the use of a particular vaccine against "Bovine...

Gene therapy approach provides tumor-attack roadmap for other cancers In a cancer treatment breakthrough 20 years in the making, researchers from the University of Pennsylvania's Abramson Cancer Center and Perelman School of Medicine have shown sustained remissions of up to a year among a small group of advanced chronic lymphocytic leukemia (CLL) patients treated with genetically engineered versions of their own T cells. The protocol, which involves removing patients' cells and modifying them...

In the latest issue of Nature, researchers at the Perelman School of Medicine at the University of Pennsylvania clarify the role of two proteins key to T-cell development. They found that one well-known protein called Notch passes off much of its role during T-cell maturation to another protein called TCF-1. T cells are required for many aspects of immunity, and understanding how these proteins influence the production of infection-fighting cells could improve treatments for immune-suppressed...
