First accurate predictive model to differentiate between dengue fever and dengue hemorrhagic fever

Researchers at the University of Texas Medical Branch have developed the first accurate predictive model to differentiate between dengue fever (DF) and its more severe form, dengue hemorrhagic fever (DHF).

New way to improve vaccines against cancer and infectious diseases

Research groups from Charité Universitätsmedizin Berlin and the University of Geneva have discovered a new way of improving vaccines against infectious diseases and for use in cancer therapies. Scientists have shown a basic new mechanism that stimulates the body's own alarm signals in case of viral infection to animate the immune system to maximum performance.

Biochemists determine first crystal structure of an immunoproteasome

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells that due to a viral infection present non-self peptides at their surface. In autoimmune diseases this mechanism is deregulated and the immune system also eliminates uninfected cells by mistake.

BioCryst fourth quarter revenues decrease to $5.2 million

BioCryst Pharmaceuticals, Inc. announced financial results for the fourth quarter and full year ended December 31, 2011.

Smoking kills healthy bacteria and leads to infection

According to a new study, smoking causes the body to turn against its own helpful bacteria, leaving smokers more vulnerable to disease.

Tissues in SIV-infected monkeys can ramp up production of Tregs

Tissue in monkeys infected with a close relative of HIV can ramp up production of a type of T cell that actually weakens the body's attack against the invading virus. The discovery, in lymph nodes draining the intestinal tract, could help explain how the HIV virus evades the body's immune defenses.

Epigenetic mechanisms maintain tolerance in T cells specific for self antigens

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens).

Starving HIV virus could be the basis for future therapy: Study

In a medical breakthrough researchers at NYU Langone Medical Center and colleagues have shown how some cells in the body can repel attacks from HIV by starving the virus of the building blocks of life.

Preterm birth interventions should be tailored for underlying risk factors and pathways

In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in Dallas, Texas, researchers will report findings that indicate that preterm birth interventions should be tailored for underlying risk factors and pathways.

Organ transplant patients can benefit from cochlear implants

Cochlear implants may be a safe, effective option for some organ transplant patients who've lost their hearing as an unfortunate consequence of their transplant-related drug regime, researchers report.

Length of residence in the U.S. increases risk of PTB among Hispanic women

The longer a Hispanic woman lives in the United States, the higher her risk of preterm birth (PTB), with nearly half of PTBs among Hispanic women occurring in those who were born in the U.S.

Study investigates how cytokine IFN-λ release is regulated

In new research appearing in this month's issue of the journal Nature Immunology, Roy Curtiss, director of the Center for Infectious Diseases and Vaccinology at the Biodesign Institute at Arizona State University, along with international collaborators, investigates the coordination of a particular type of immune response, involving the release of of IFN-λ- a cell-signaling protein molecule known as a cytokine.

IKBKE protein plays two roles in tobacco-related NSCLC

Researchers at Moffitt Cancer Center in Tampa, Fla., have discovered that the immune response regulator IKBKE (serine/threonine kinase) plays two roles in tobacco-related non-small cell lung cancers. Tobacco carcinogens induce IKBKE and, in turn, IKBKE induces chemotherapy resistance.

Gene therapy succeeds in the second blind eye for three patients

Three people have now have reported a dramatic improvement in vision after having gene therapy in both eyes after having lost their eyesight as children.

Readministration of gene therapy improves vision in three patients with LCA

Gene therapy for congenital blindness has taken another step forward, as researchers further improved vision in three adult patients previously treated in one eye.

Study implicates 'arms race' between genes and germs

Biologists have found new evidence of why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs--even though some of those genes make vertebrate animals susceptible to infections and to autoimmune diseases.

Routine 4CMenB immunizations effective against meningococcal strains in infants

Administration of routine infant immunizations with a vaccine for serogroup B Neisseria meningitidis, a bacterium that is a cause of serious disease such as sepsis and meningitis, was effective against meningococcal strains and produced minimal interference with the response to the routine vaccinations, according to a study in the February 8 issue of JAMA.

New immunotherapy combination prolongs survival in dogs with NHL

A new immunotherapy for companion dogs with advanced-stage non-Hodgkin lymphoma (NHL) has been shown to improve survival while maintaining quality of life, according to a study published in the journal Scientific Reports.
