MSU scientists show how special genes stay open to fight against infections

A new discovery at Michigan State University has revealed how special genes stay open for business, helping diagram a mechanism that plays a key role in fighting inflammation and infections.

Researchers explain why secondary infection with MRSA kills influenza patients

Researchers have discovered that secondary infection with the Methicillin-resistant Staphylococcus aureus (MRSA) bacterium (or "superbug") often kills influenza patients because the flu virus alters the antibacterial response of white blood cells, causing them to damage the patients' lungs instead of destroying the bacterium.

Scientists find new functions of ANG protein that plays key role in regulation of blood cell formation

Tufts Medical Center and Tufts University scientists have found exciting, new functions of the protein angiogenin that play a significant role in the regulation of blood cell formation, important in bone marrow transplantation and recovery from radiation-induced bone marrow failure.

New fluorescence microscopy approach improves image resolution by merging three views into one

Researchers have developed a new fluorescence microscopy approach that significantly improves image resolution by acquiring three views of a sample at the same time. Their new method is particularly useful for watching the dynamics of biological processes, which can provide insights into how healthy cells work and what goes wrong when diseases occur.

Naturally-occurring protein controls shape and activity of white blood cells to combat sepsis

Boosting levels of a protein that controls the shape and activity of a crucial group of white blood cells improves survival and recovery chances during sepsis.

New drug could help decrease symptoms of asthma

The first new asthma pill for nearly 20 years has the power to significantly reduce the severity of the condition, a study led by the University of Leicester has found.

New research examines biomechanics of galectin-3

A new study, published in Biochemistry this week, examines the biomechanics of sugar-seeking proteins. Specifically, it delves into galectin-3's interaction with glycosaminoglycans (GAG) and proteoglycans.

Experimental immunotherapeutic strategy may pave way for new treatments against lymphoma

Lymphoma is a cancer that affects lymphocytes, a type of white blood cell. The disease originates in a lymphoid organ (lymph node, spleen, or bone marrow) before spreading through the blood to infiltrate not only other lymphoid organs but also other tissues.

Research could provide new insights into finding cure for chronic infections

New research has taken us a step closer to finding a cure for human immunodeficiency virus (HIV), as well as other infections including the glandular fever virus, which is associated with the development of lymphoma.

Researchers identify crucial innate immunity role for gene linked to ARC syndrome in children

UT Southwestern Medical Center researchers have found an important innate immunity role for a gene linked to a rare, fatal syndrome in children. Their study has implications for a much more common disease: tuberculosis.

Malfunctioning of molecular signaling system suppresses mature blood cells battling against sepsis

When the body encounters an infection, a molecular signaling system ramps up the body's infection-fighting system to produce more white blood cells to attack invading bacteria.

Researchers identify how precise control of inflammation could lead to bone repair

In their mission to design new biomaterials that promote tissue regeneration, Drexel University researchers have identified how inflammation, when precisely controlled, is crucial to bone repair.

Novel conjugate therapy shows promise in destroying ALL cells with few side effects

Researchers at UC Davis and Ionis Pharmaceuticals have developed a hybrid treatment that harnesses a monoclonal antibody to deliver antisense DNA to acute lymphoblastic leukemia (ALL) cells and that may lead to less toxic treatments for the disease.

Male hormones can reverse biological drivers of aging, study shows

Telomerase, an enzyme naturally found in the human organism, is the closest of all known substances to a "cellular elixir of youth." In a recent study, Brazilian and US researchers show that sex hormones can stimulate production of this enzyme.
