New study finds how cells with damaged DNA alert the immune system

...A damage pathway in regulating immune responses to infectious diseases, but given what we have shown here, it is certainly plausible that it contributes to the expression of the NKG2D ligand," said Raulet. "It may also be that the Rae1 ligand helps trigger T cell responses that contribute to long term specific ...

Researcher at UGA College of Veterinary Medicine identifies new way of combating viral diseases

...l of Virology, Thomas Hodge, research professor of infectious diseases at the veterinary college, and his colleagues report that blocking a protein that helps transport viruses out of a cell keeps these four viruses from reproducing and infecting other cells. Most antiviral therapies target the virus itself, b...

UW scientists report a new method to speed bird flu vaccine production

...on because they are not known to carry any unknown infectious agents and do not cause tumors. According to Kawaoka, "application of the new system may be especially advantageous in situations of outbreaks of highly pathogenic avian influenza viruses." When a new strain of highly virulent influenza emerges to ...

Stolen gene allows insect virus to enter cells

...t it? These viruses actually generate two types of infectious particles, Blissard explains: one type specialized to infect gut cells, and another that spreads infection in other parts of the insect. The latter type uses F to enter cells. An ancestor of today's baculoviruses "might have just existed as a diarrhe...

Grand Challenges in Global Health initiative funds Yale project

...er diseases are made from weakened versions of the infectious agent. These cannot be studied in human trials unless researchers are confident that they are safe. "A big need in the world of vaccine development is the ability to predict whether vaccines for humans are safe and effective," said Flavell. "We are ...

... uses. Although the replicon does not produce the infectious virus, the HCV replicon system represents the best available system for examining the impact of opiates on HCV at the time of their research study. Similar to their previous results, the authors found that MW and PW increased levels of HCV replico...

"If your neutrophils work normally, you might be able to shut down thisinfection," said Southwick, who worked on the study with a team of UF researchers and investigators from ...

UT Southwestern researchers develop screening test for cells that activate immune system

...in identifying biothreat agents because it detects infectious pathogens with high sensitivity. Dr. Takashima said he hopes to garner additional funding to discover potent immuno-stimulatory drugs by screening high-quality libraries of compounds. Doing so may be the first step toward developing a new class o...

CO2 sensing proves critical for fungal pathogens to adapt to life in air and human hosts

... which is known to be a key process for generating infectious spores, and the CA enzyme plays a central role in the process. Together with the accompanying work by Mühlschlegel and colleagues, this study implicates a key role for CO2 in growth and differentiation in the fungal kingdom. The identification of a...

New vaccine platform may fight infections with causes from influenza to bioterrorism

...nnot be protected against polio, the flu and other infectious agents with existing vaccines that depend on a normal T-cell response. As such, the researchers were motivated to develop CD4+ T-cell–independent therapeutic strategies to meet this growing need. "While we'll need to replicate these findings in lar...

Mechanism for Epstein-Barr virus protein's role in blood cancers discovered
