Dendritic cells turn T cells into T regs

Regulatory T cells (also known as T regs) suppress some of the immune system's more inappropriate responses, preventing it from attacking the body's own tissues and stifling its activity once invading microbes have been fought off.

Byproduct of cholesterol metabolism blocks heart health benefits of estrogen

New findings by UT Southwestern Medical Center researchers show that a byproduct of cholesterol metabolism interferes with the beneficial effects estrogen has on the cardiovascular system, providing a better understanding of the interplay between cholesterol and estrogen in heart disease.

N-cofilin molecule protects from neuronal disorders

Many neuronal disorders, including epilepsy, schizophrenia and lissencephaly – a form of mental retardation - result from abnormal migration of nerve cells during the development of the brain.

Zebrafish shed light on human mitochondrial diseases

Zebrafish can now be used to study COX deficiencies in humans, a discovery that gives scientists an unprecedented window to view the earliest stages of mitochondrial impairments that lead to potentially fatal metabolic disorders, according to researchers at the University of Oregon.

Potential solution to Candida parapsilosis infection

Infection with the fungus Candida parapsilosis is a major problem for individuals in intensive care units, as well as for premature infants and immunocompromised adults.

Study suggests brain tumors need treatment with multiple 'targeted' drugs

Researchers at Dana-Farber Cancer Institute have shown that several, rather than just one, cell-growth switches are simultaneously overactive in many brain tumors and other solid tumors, explaining why treatment with just a single "targeted" switch-blocking drug often yields disappointing results.

Platelets help white blood cells fight inflammation

Scientists have shown for the first time that platelets, the cells needed for blood clotting, help white blood cells called neutrophils fight inflammation.

Older men chasing younger women contributes to human longevity

It turns out that older men chasing younger women contributes to human longevity and the survival of the species, according to new findings by researchers at Stanford and the University of California-Santa Barbara.

Proteins Nox1 and Nox2 play important role in amyotrophic lateral sclerosis

University of Iowa researchers investigating the basic biology of cell signaling have made a discovery that may have therapeutic implications for amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases.

Women undergoing IVF to donate eggs for stem cell research in return for reduced treatment costs

The Medical Research Council (MRC) is to fund a research proposal from a team at the North East England Stem Cell Institute (NESCI) for a project to find ways of improving the efficiency of therapeutic cloning - a technique which would allow scientists to create patient-specific stem cells and develop regenerative therapies for many debilitating conditions such as diabetes, heart disease and Parkinson’s disease.

Unique role for blood formation gene MLL identified

All blood cell production in adults depends on the steady work of a vital gene that if lost results in early bone marrow failure, Dartmouth Medical School cancer geneticists have found.

Delivery of anti-cancer drug paclitaxel on a tiny ball of gold

Rice University chemists have discovered a way to load dozens of molecules of the anti-cancer drug paclitaxel onto tiny gold spheres. The result is a tiny ball, many times smaller than a living cell that literally bristles with the drug.

Shape encoding may start in the retina

New evidence from the University of Southern California suggests that there may be dedicated cells in the retina that help compile small bits of information in order to recognize objects.

Scientists isolate stem cells in womb tissue

Scientists in Australia have found a way of identifying probable stem cells in the lining of women's wombs. The finding opens up the possibility of using the stem cells for tissue engineering applications such as building up natural tissue to repair prolapsed pelvic floors.

New Rensselaer tools speed stem cell research

Engineers at Rensselaer Polytechnic Institute have developed tools to help solve two of the main problems slowing the progress of stem cell research - how to quickly test stem cell response to different drugs or genes, and how to create a large supply of healthy, viable stem cells to study from only a few available cells.
