Source of crucial immune cell in the skin discovered - may lead to tumor immunotherapy

Mount Sinai School of Medicine researchers have identified the precursors of cells in the skin that are part of the first line of defense against invading pathogens. The study appears on Nature Immunology's website.

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme, an important contributor to the vast majority of human cancers. Understanding the physical shape of the protein has led to a better understanding of how it acts to immortalize cells - and should help scientists design broadly effective cancer drugs.

Counting cells that ensure gene balance

Two are one too many - this is the motto used by cells of a female organism: These contain two X chromosomes, one of which always becomes inactivated.

New research has implications for treating muscular dystrophy

In a surprising discovery with implications for treating muscular dystrophy, researchers at the University of Utah School of Medicine and other institutions have identified a major source of origin for two groups of adult cells that regulate muscle repair.

Malaria parasite plasmodium shown to develop in lymph nodes

In the first quantitative, real-time imaging study of the travels of the malaria parasite Plasmodium through mammalian tissue, researchers at the Pasteur Institute in Paris found the parasites developing in an unexpected place: the lymph nodes.

Taste encoding in the brain

Instantly reacting to the sweet lure of chocolate or the bitter taste of strychnine would seem to demand that such behavioral responses be so innate as to be hard-wired into the brain.

Scientists design a fluorescent sensor capable of measuring intracellular acidity

The colouring agents traditionally used to stain organic tissues are no longer sufficient to meet today’s needs. The study of cell metabolism can only advance with better tools than those currently available.

Astrocytes play a direct role in controlling blood flow in the brain - influencing Alzheimer's

New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease.

Study to look for links between the nervous system and fatal heart rhythm

Finding out why seemingly healthy people experience ventricular fibrillation, a fatal irregular heart rhythm, could eventually lead to better methods of early detection, according to a Medical College of Georgia researcher.

Scientists discover how HIV infects healthy cells

Using sophisticated detection methods, researchers at the Saint Louis University Institute for Molecular Virology (IMV) have demonstrated the molecular mechanism by which the HIV virus infects, or integrates, healthy cells. The discovery could lead to new drug treatments for HIV.

New cancer detection method

University of Florida researchers say they are a step closer to a technique to easily detect a wide variety of cancers before symptoms become apparent.

Generation of neoantigenic epitopes after posttranslational modification of Type II collagen by factors present within the inflamed joint

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the joints, which gradually erodes the cartilage and bone.

Bacterial DNA and IVF contamination risk on New Scientist

Some children conceived by a common method of IVF could be carrying chunks of bacterial DNA in their chromosomes, according to a study in mice. The researchers who conducted the work say that such accidental genetic modification would be very rare, but they argue that fertility doctors should take more precautions to exclude it.

Scientist finds first evidence of a living memory trace

An international team of scientists for the first time has detected a memory trace in a living animal after it has encountered a single, new stimulus.

Sperm stem cells research provides exciting findings

New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body.

Olfactory epithelium plays a critical role in pheromone detection

Howard Hughes Medical Institute researchers have discovered that pheromones essential for mating behavior in mice are recognized by the nose and not by the vomeronasal system, as researchers had long suspected.

First step in exploring the GnRH reproduction-related circuitry in the brain

Howard Hughes Medical Institute researchers have discovered a vast network of neurons in the brain of mice that governs reproduction and controls the effects of reproductive status on other brain functions.

LGC licenses first DNA test for response to schizophrenia treatment from the Institute of Psychiatry, King’s College London

LGC, Europe's leading independent analytical laboratory providing advanced chemical, biochemical and forensic analysis, has announced an exclusive agreement with King’s College London to offer the first pharmacogenetic screening service which will predict whether a patient with schizophrenia will respond positively to the antipsychotic drug clozapine.

New Flu Chip can determine the genetic make-up of types of flu virus in 11 hours

A novel "Flu Chip" developed at the University of Colorado at Boulder that can determine the genetic signatures of specific influenza strains from patient samples within hours may help world health officials combat coming epidemics and pandemics.

Sleeping sickness parasite shows how cells divide their insides

Researchers at Yale have brought to light a mechanism that regulates the way an internal organelle, the Golgi apparatus, duplicates as cells prepare to divide, according to a report in Science Express.
