 A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as some cancers, such as melanoma.Effective response by key immune cells in the body, called T cells, is crucial for control of many widespread chronic viral infections such as HIV and hepatitis B...

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.In experiments conducted in both mice and monkeys, rapamycin can stimulate the formation of memory CD8 T cells, which enable the immune system to respond faster and stronger to an infectious agent upon a second encounter.The results were published online ahead of print June 21 in Nature. The...

Copenhagen, Denmark, Friday 12 June 2009: First line treatment with anakinra (an interleukin-1 (IL-1) receptor antagonist), results in a 'good' clinical response (ACRp90) in patients newly diagnosed with systemic onset juvenile idiopathic arthritis (SoJIA), and restores the deficient IL-18 response of natural killer (NK) cells*, according to a new study presented today at PReS 2009, a joint congress with the 2009 Congress of the European League Against Rheumatism (EULAR) in Copenhagen,...

 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.  In their initial response, these immune cells, known as cytotoxic T lymphocytes, or CTLs, kill cells infected with pathogens. They also provide long-term protection against pathogens by "remembering" which proteins the pathogen makes. Targeting the ability of these CTLs to...

 Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions.In the largest study of its kind, researchers found that in diseased cells "” such as cancer cells "” that are also infected with HIV, almost all the virus was packed into macrophages, whose job is to "eat" invading disease agents.What's...

If we imagine our immune system to be a police force for our bodies, then previous work has suggested that the Lymph nodes would be the best candidate structures within the body to act as police stations "“ the regions in which the immune response is organized. However, Prof. Burkhard Becher, University of Zurich, suggests in a new paper "“ published in this week's issue of PLoS Biology "“ that lymph nodes are not essential in the mouse in marshalling T-cells (a main immune...

Identifying one of the processes that plays a role in naïve and memory T-cells' growth and production could one day lead to better vaccines and possibly more effective cancer immunotherapy, said researchers at Baylor College of Medicine and Texas Children's Hospital in a report that appears in the current edition of Nature Immunology. In previous work, Dr. Daniel Lacorazza, assistant professor of pathology at BCM, along with his research team, identified a...

Stem cells of any kind are defined by their eternal nature, reproducing themselves and providing a pool of cells from which more differentiated tissues arise.Now a group of researchers from Baylor College of Medicine in collaboration with researchers in Australia and the United Kingdom, demonstrate that two specific "sister" genes that control transcription play often overlapping roles in maintaining this pool of hematopoietic or blood cell-forming stem cells.Redundant rolesIn a report in the...

barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
