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...

Some monkeys can survive infection by SIV, a relative of HIV, and not develop AIDS. Their immune systems appear to display a pattern of "peaceful coexistence" rather than the all-out conflict provoked by HIV when it infects humans. SIV's natural hosts are non-human primates found in central Africa, including sooty mangabeys and African green monkeys — both species whose SIV infections have been studied in captivity -- as well as other species such as mandrills, drills and suntailed...

(Ivanhoe Newswire) — Good news! Researchers have discovered a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer. “The technique involves delivering DNA into the immune system's instructor cells. The DNA directs these cells to overproduce a specific protein that jumpstarts important killer T cells, called CD8 T cells. These killer cells are typically repressed in patients who have...

Study in Nature Medicine could lead to novel therapy for cancer In a study published in Nature Medicine, Loyola researchers report on a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer. The technique involves delivering DNA into the immune system's instructor cells. The DNA directs these cells to overproduce a specific protein that jumpstarts important killer T cells. These killer cells...

What if we could engineer a liver or kidney from a patient's own stem cells? How about helping regenerate tissue damaged by diseases such as osteoporosis and arthritis? A new UCLA study bring scientists a little closer to these possibilities by providing a better understanding how tissue is formed and organized in the body. A UCLA research team discovered that migrating cells prefer to turn right when encountering changes in their environment. The researchers were then able to translate...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
