Research uncovers natural defense mechanism that inactivates C. diff toxins

Groundbreaking research encompassing Case Western Reserve University School of Medicine and University Hospitals Case Medical Center, has uncovered a natural defense mechanism that is capable of inactivating the toxin that spreads Clostridium difficile, or C. diff, an increasingly common bacterial infection in hospitals and long-term care settings.

Scientists discover key defense mechanism against C. difficile infection

Researchers have discovered a key mechanism used by intestinal cells to defend themselves against one of the world's most common hospital-acquired bacterial infections - a mechanism they think they can exploit to produce a therapy to protect against the effects of the antibiotic-resistant bacteria.

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.

Single-molecule imaging reveals how cells prepare to interact with biochemical signals

Researchers at Harvard Medical School have discovered that structural elements in the cell play a crucial role in organizing the motion of cell-surface receptors, proteins that enable cells to receive signals from other parts of the organism.

Blocking pathway for generating energy can kill cancer cells

Cancer Research UK scientists have found that blocking the pathway used by some kidney cancer cells to generate energy can kill the cancer cells, sparing the healthy ones.

Harmless bacteria re-engineered to fight a deadly strain

Scientists in Singapore have re-engineered a harmless strain of bacteria to fight another common, drug-resistant microbe that spreads in hospitals and is deadly to patients with weak immune systems.

Researchers identify mesothelin antibody that could detect early-stage ovarian cancer

Using a new approach to developing biomarkers for the very early detection of ovarian cancer, researchers at Rush University Medical Center have identified a molecule in the bloodstream of infertile women that could one day be used to screen for those at high risk for the disease — or even those with early-stage ovarian cancer.

Toclizumab for juvenile rheumatoid arthritis

The arthritis drug Toclizumab could be a boon for hundreds of children suffering from severe arthritis. It has been re-launched in children after being already licensed for the treatment of adults. At least two thirds of children taking tocizilumab have been able to return to a normal life, after many were bedridden or forced into wheelchairs by the disease, the clinical studies reveal.

Insight into how molecular motor proteins save energy

The transport system inside living cells is a well-oiled machine with tiny protein motors hauling chromosomes, neurotransmitters and other vital cargo around the cell. These molecular motors are responsible for a variety of critical transport jobs, but they are not always on the go. They can put themselves into "energy save mode" to conserve cellular fuel and, as a consequence, control what gets moved around the cell, and when.

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.
