Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

...wn as pneumonic plague. This form of the infection progresses faster, spreads easier from person to person, and is far more deadly, killing 100 percent of those who do not receive the right antibiotics soon after exposure. "There is," the authors note, "an urgent need for vaccine development." One of this micr...

Genetic links could unlock clues to leading cause of blindness

...sease in humans allows researchers to study how it progresses in the animals, which could lead to better treatments and even a cure. "Stopping the development of the disease is something the monkeys will help us do that we can't do with humans," said William W. Dawson, a UF professor of ophthalmology and physi...

U of MN researchers reverse memory loss in mice

...e mice serve as a model that shows how the disease progresses as well as the possibility that memory loss can be reversed. The research suggests that the same reversal may be possible in humans, and that people with Alzheimer's disease may be able to recover memory and improve in cognitive function if they can ...

...ble to observe, for the first time, that rejection progresses from the outside of the heart to the inside," said Ho. "Up to now, this phenomenon hasn't been observed in pre-clinical or clinical research because biopsy samples are very limited in location and size." The reported findings also have broader impli...

U-M scientists identify major psoriasis susceptibility gene

The PSORS1 gene is actually one of over 20 different varieties (scientists call them alleles) of a gene called HLA-C. "In terms of our grocery store analogy, think of PSORS1 as one of 20 'brands' of HLA-C on t...

Measuring artery repair cells could become new heart disease test

Current methods for measuring EPCs ?which can represent as few as one out of 10,000 cells in a given blood sample ?are subjective and time-consuming, the researchers said. As...

MS is an autoimmune disease believed to result from misguided immune system attacks on nervous system tissues. It comes in various forms and affects an estimated 400,000 Am...

NYU algorithm enhances ability to detect cancer genes

The NYU algorithm estimates the location of tumor suppressor genes by analyzing segmental deletions in the genomes from cancer patients and the spatial relation of the deleted segments to any specific genomic interval. Since th...

From October 2004 through July 2005, a Marburg outbreak in Angola resulted in 252 cases of hemorrhagic fever, with 90% of the cases fatal. Although most of the cases were confirmed through PCR as c...
