Research on why and how malaria parasites go undetected in the placenta of pregnant women

Collaborative research between LSTM and the University of Copenhagen, published last week in the Proceedings of the National Academy of Sciences, have answered a long standing mystery, why and how malaria parasites go unnoticed by the immune defences of pregnant mothers.

Emory team identifies conditions that make memory T cells slip away during chronic infections

After recovering from the flu or another acute infection, your immune system is ready to react quickly if you run into the same virus again. White blood cells called memory T cells develop during the infection and help the immune system remember the virus and attack it if it comes back.

Use of insecticide-treated bednets linked to local resurgence of malaria, study says

"Insecticide-treated bednets, whose use is being widely promoted in Africa to combat malaria, may paradoxically be linked to local resurgence of the disease," according to a study published in the Lancet on Thursday, the Independent reports.

Flu immunization targets fall short for health workers and pregnant women

According to a new survey despite recent improvements in influenza vaccination rates among U.S. health care personnel, their rates for the 2010-2011 flu season still fell short of national health objectives.

Mosquitoes fast to develop resistance against insecticide-treated bed nets

According to a study from Senegal mosquitoes are quick to develop resistance to insecticide-treated nets. This has raised concerns that a leading method of preventing the disease may be less effective than previously thought.

Researchers discover new mechanism that controls ageing in WBCs

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered a new mechanism controlling ageing in white blood cells.

Regular exercise could help prevent brain damage linked with Alzheimer's

Regular exercise could help prevent brain damage associated with neurodegenerative diseases like Alzheimer's, according to research published this month in Elsevier's journal Brain, Behavior, and Immunity.

Researchers identify unknown link between migration of WBCs to infected tissues, immune memory

Researchers from Dr. Woodland's lab at the Trudeau Institute have now identified a previously unknown link between the migration of white blood cells to infected tissues and the ability of these cells to survive and become long-lived memory cells after the infection has been cleared.

BCG vaccine can help immune system recognise cancer cells as 'foreign'

Scientists have found a potential new mechanism to stimulate the body's own ability to fight cancer using Baculillus Calmette-Guerin (BCG) - the germ commonly used to inoculate against tuberculosis.

New computational model could forecast cholera outbreaks

Just as the rainy season is driving a new surge of cholera cases in Haiti, a new computational model could forecast where outbreaks are likely to occur.

57 genes associated with multiple sclerosis

An international research team has found nearly 30 genetic risk factors that predispose to developing multiple sclerosis. It brings to more than 50 the total number of genetic clues to the disease. The research, published in Nature, will help identify risk factors and perhaps future treatments or even a cure, hopes the MS Society.

Gene therapy to combat leukemia

In a medical breakthrough scientists have found that gene therapy could be used to cure leukemia. Researchers at the University of Pennsylvania engineered patients' own pathogen-fighting T-cells to target a molecule found on the surface of leukemia cells. These genetically modified T-cells were grown outside of the body and infused back into patients suffering from late-stage chronic lymphocytic leukemia (CLL), which affects the blood and bone marrow and is the most common form of leukemia.

Sleep deprivation negatively affects school-age children

Going back to school should not be just an excuse for kids to get new clothes and school supplies. Instead, say University of Alabama at Birmingham experts, it also should be a time to get them back to healthier sleep schedules.

Moderate exercise may help prevent cognitive decline after bacterial infection

A small amount of exercise shields older animals from memory loss following a bacterial infection, according to a study in the August 10 issue of The Journal of Neuroscience.

MAVS prion-like proteins are involved in innate immunity: Discovery

A person's ability to battle viruses at the cellular level remarkably resembles the way deadly infectious agents called prions misfold and cluster native proteins to cause disease, UT Southwestern Medical Center researchers report.

Researchers clarify role of two proteins key to T-cell development

In the latest issue of Nature, researchers at the Perelman School of Medicine at the University of Pennsylvania clarify the role of two proteins key to T-cell development.

Triple threat of catching three varieties of flu in one season

Each year, 200,000 Americans are hospitalized due to flu-related complications. That number can rise or fall - often dramatically - based on the effectiveness of the selected flu vaccine, said Dr. Jorge Parada, director of infection prevention and control at Loyola University Health System.

Entomologist to study how immune system responds to rickettsial infection

Summer for most people means time spent outdoors, which could also mean increased exposure to bugs and, possibly, arthropod-borne diseases, such as "rickettsial diseases" - infectious diseases spread by bacteria, which, generally, are transmitted by lice, fleas, ticks and mites.

Novel DNA sensing pathway linked to increased susceptibility to malaria

Scientists at the University of Massachusetts Medical School have uncovered a novel DNA-sensing pathway important to the triggering of an innate immune response for malaria. Activation of this pathway appears to stimulate production of an overabundance of type-1 interferon by the immune system that may contribute to inflammation and fever in malaria patients and could play a part in susceptibility for the most common and lethal form of malaria known as plasmodium falciparum.

Virginia Tech student receives prestigious award for cellular signaling receptor study linked to diabetes, obesity

Stephanie Nicole "Nikki" Lewis, a graduate student in the interdisciplinary doctoral program in genetics, bioinformatics, and computational biology at Virginia Tech, has been awarded the prestigious Ruth L. Kirschstein National Research Service Award for Predoctoral Research through the National Institutes of Health for her study of a cellular signaling receptor that is associated with chronic inflammatory diseases such as diabetes, obesity, and inflammatory bowel disease.
