After being infected with SIV, rhesus macaques that had more of a certain type of immune cell in their gut than others had much lower levels of the virus in their blood, and for 6 months after infection were better able to control the virus After being infected with simian immunodeficiency virus (SIV) in a laboratory study, rhesus macaques that had more of a certain type of immune cell in their gut than others had much lower levels of the virus in their blood, and for six months after...

University of Cincinnati (UC) researchers have found that an imbalance in the regulation of certain T cells–the cells in the body that fight off infection or attack the system in certain autoimmune diseases–may put certain people at a higher risk of having recurrent cases of Clostridium difficile, or C. Diff, infection. These findings are being presented via poster during Digestive Disease Week, Monday, May 21, 2012, in San Diego. C. difficile is a bacterium that can be...

Scientists at The Scripps Research Institute have made an important discovery about the internal programming of B cells, the immune cells that make antibodies against infections. The finding opens the way for the development of vaccines that can work more efficiently and hints at therapies for conditions in which B cells cause harm–such as the autoimmune disease lupus erythymatosus, severe allergies, and B-cell lymphomas. The discovery reveals that B cells produce special proteins to...

Loyola researchers are reporting surprising findings about a molecule that helps ramp up the immune system in some cases and suppress it in others. The finding eventually could lead to new drugs to regulate the immune system by, for example, revving it up to attack tumor cells or tamping it down to prevent the rejection of transplanted organs. The study is published online ahead of print in the Journal of Immunology. Senior author is Makio Iwashima, PhD, an associate professor in the...

The characterisation of a rare immune cell´s involvement in antibody production and ability to ℠remember´ infectious agents could help to improve vaccination and lead to new treatments for immune disorders, say researchers from the Walter and Eliza Hall Institute. The cells, called T follicular helper cells, represent less than half of one per cent of all immune cells, but play a critical role in antibody production and developing long-lasting immunity. However, the cells...

The hallmark loss of helper CD4+ T cells during human immunodeficiency virus (HIV) infection may be a red herring for therapeutics, according to a study published on March 26th in the Journal of Experimental Medicine. HIV preferentially infects CD4+ T cells, immune cells required to generate protective antibodies. In many people, this leads to a progressive drop in CD4+ T cell numbers–and the more the numbers fall, the faster AIDS develops. HIV-induced cell loss includes both 'naive'...

Using data from the Collaboration of Observational HIV Epidemiological Research in Europe (COHERE), Jim Young and colleagues from The Opportunistic Infections Project Team of COHERE show in this week's PLoS Medicine that in successfully treated patients, the risk of a new AIDS event or death follows a CD4 cell count gradient in patients with viral suppression. An increase in CD4 cell count provides the greatest benefit for patients with a CD4 cell count below 200 cells/µL but still...
