Researchers identify new mechanism that protects from bacterial infections

An international team led by the University if Barcelona has identified a new antibacterial mechanism that protects macrophages - defense cells in the immune system- from the infection of the bacteria Salmonella enterica serovar Typhimurium, a pathogen associated with several gastrointestinal diseases.

Researchers uncover novel virulence strategies employed by Leishmania parasite

Professor Albert Descoteaux of INRS-Institut Armand-Frappier Research Centre and his team have discovered novel virulence strategies employed by the Leishmania parasite.

Study shows syringe-like device acts as traffic cop directing bacteria to carry out infection

A study has found that a syringe-like device used to invade intestinal cells also acts as a traffic cop -- directing bacteria where to go and thereby enabling them to efficiently carry out infection.

Magnesium could be safe, cost-effective therapeutic intervention for genetic coagulation disorder

An international team of scientists was able to demonstrate in mouse and patient studies, how magnesium affects the production of blood platelets and that the TRPM7 channel function plays a key role in this process. Scientists of the Rudolf Virchow Center and the Hospital of the University of Würzburg were primarily involved in this study. Their results were published in the current journal "Nature Communications".

UIC researchers discover molecular switch that allows salmonella bacteria to fight immune system

Researchers at the University of Illinois at Chicago have discovered a molecular regulator that allows salmonella bacteria to switch from actively causing disease to lurking in a chronic but asymptomatic state called a biofilm.

Johns Hopkins study shows high doses of cocaine kill brain cells

Working with mice, researchers at Johns Hopkins have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy, a process in which cells literally digest their own insides. Their results, moreover, bring with them a possible antidote, an experimental compound dubbed CGP3466B.

Emory University immunologists identify long-lived antibody-producing cells in bone marrow

Immunologists from Emory University have identified a distinct set of long-lived antibody-producing cells in the human bone marrow that function as an immune archive.

Inhibiting cancer-promoting prolactin causes unconventional cell death in preclinical research

Under stress from chemotherapy or radiation, some cancer cells dodge death by consuming a bit of themselves, allowing them to essentially sleep through treatment and later awaken as tougher, resistant disease.

Genetic basis of hereditary disease causes severe brain atrophy in Jews of Moroccan ancestry

Ben-Gurion University of the Negev (BGU) researchers have unraveled the genetic basis of a hereditary disease that causes severe brain atrophy, mental retardation and epilepsy in Jews of Moroccan ancestry, according to a study published this week online in the Journal of Medical Genetics.

New video tracking system could help select most viable sperm

To improve their chances of success, in vitro fertilization (IVF) clinics need to assess the viability of the sperm they use. Now doctors may soon have a new technique to help them sort the good sperm cells from the less viable ones: a tracking system, developed by a team of researchers from four European institutions, that takes 3-D movies of living sperm.

Study shows how deadly Candida albicans might be rendered harmless

Candida albicans is a double agent: In most of us, it lives peacefully, but for people whose immune systems are compromised by HIV or other severe illnesses, it is frequently deadly. Now a new study from Johns Hopkins and Harvard Medical School shows how targeting a specific fungal component might turn the fungus from a lion back into a kitten.

New research provides unprecedented clarity to aging process

For the first time, scientists at Fred Hutchinson Cancer Research Center have defined key events that take place early in the process of cellular aging.

Disruption of circadian rhythms cause accelerated neurodegeneration and premature death

New research at Oregon State University provides evidence for the first time that disruption of circadian rhythms - the biological "clocks" found in many animals - can clearly cause accelerated neurodegeneration, loss of motor function and premature death.

Nanoparticles have a detrimental effect on the fish brain

Scientists at the University of Plymouth have shown, for the first time in an animal, that nanoparticles have a detrimental effect on the brain and other parts of the central nervous system.

Nanoscopic findings may lead to new experimental methods for early multiple sclerosis diagnosis

Laboratory studies by chemical engineers at UC Santa Barbara may lead to new experimental methods for early detection and diagnosis -- and to possible treatments -- for pathological tissues that are precursors to multiple sclerosis and similar diseases.

Scientists find new replicating mechanism of Salmonella bacteria

New findings by National Institutes of Health scientists could explain how Salmonella bacteria, a common cause of food poisoning, efficiently spread in people. In a study published this week in the Proceedings of the National Academy of Sciences, researchers describe finding a reservoir of rapidly replicating Salmonella inside epithelial cells. These bacteria are primed to infect other cells and are pushed from the epithelial layer by a new mechanism that frees the Salmonella to infect other cells or be shed into the intestine.

Mutant ATPase blocks autophagy partway and causes multi-tissue degenerative disease

It's important to finish what you start, say Jeong-Sun Ju and researchers from Washington University School of Medicine, St. Louis. In the December 14, 2009 issue of the Journal of Cell Biology (www.jcb.org), Ju et al. reveal how a mutant ATPase blocks autophagy partway through to cause a multi-tissue degenerative disease.

Researchers discover why Lou Gehrig's disease speeds along more rapidly in some patients than others

University of Florida scientists have discovered why a paralyzing brain disorder speeds along more rapidly in some patients than others - a finding that may finally give researchers an entry point toward an effective treatment for amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease.

Link found between Parkinson's disease genes and manganese poisoning

A connection between genetic and environmental causes of Parkinson's disease has been discovered by a research team led by Aaron D. Gitler, PhD, Assistant Professor in the Department of Cell and Developmental Biology at the University of Pennsylvania School of Medicine.
