Insight into possible new approaches in vaccine development for blood-borne infections and HIV

White blood cells called neutrophils, which are the first line of defense against infection, play an unexpected role by boosting antibody production, according to research led by Mount Sinai School of Medicine. The findings suggest neutrophils have multiple roles within the immune system and function at levels previously unknown to the scientific community. The research, published in Nature Immunology, provides groundbreaking insight into possible new approaches in vaccine development for blood-borne infections and HIV.

Scientists capture high-quality images of immune cell trafficking in a beating heart

Blood flow to the heart often is interrupted during a heart attack or cardiac surgery. But when blood flow resumes, the heart may still falter. That's because collateral damage can occur as blood re-enters the heart, potentially slowing recovery and causing future cardiac troubles.

SLU professor to study how antithrombin might prevent premature death from heart disease

Alireza "Ray" Rezaie, Ph.D., professor of biochemistry and molecular biology at Saint Louis University School of Medicine, has received a $1.52 million NIH grant to study how the key blood clotting inhibitor antithrombin might be exploited to prevent premature death from heart disease.

Physiologists, neuropathologists identify origin of cancer metastasis formation

It is not primary tumors that are responsible for the majority of cancer deaths, but rather their metastases. Physiologists and neuropathologists from the University of Zurich have now identified the origin of metastasis formation, thereby becoming the first to reveal the pathway of metastasizing intestinal cancer cells out of the blood stream. The results allow new approaches in the development of cancer therapies.

Methylation provides signal of unique mix of leukocytes

When a person is sick, there is a tell-tale sign in their blood: a different mix of the various types of immune cells called leukocytes. A group of scientists at several institutions including Brown University has discovered a way to determine that mix from the DNA in archival or fresh blood samples, potentially providing a practical new technology not only for medical research but also for clinical diagnosis and treatment monitoring of ailments including some cancers.

Human immune response: TCD scientists make breakthrough which could lead to new drug therapies

A team of researchers at Trinity College Dublin’s School of Medicine has gained new insights into a protein in the human immune system that plays a key role in the protective response to infection and inflammation. The research findings have just been published in the internationally renowned peer-reviewed Journal of Biological Chemistry.

Eltrombopag can raise blood cell levels in some people with severe aplastic anemia

Eltrombopag, a drug that was designed to stimulate production of platelets from the bone marrow and thereby improve blood clotting, can raise blood cell levels in some people with severe aplastic anemia who have failed all standard therapies.

Study examines how cells exploit gene sequences to cope with toxic stress

Toxic chemicals wreak havoc on cells, damaging DNA and other critical molecules. A new study from researchers at MIT and the University at Albany reveals how a molecular emergency-response system shifts the cell into damage-control mode and helps it survive such attacks by rapidly producing proteins that counteract the harm.

Investigators identify cell replacement/tissue repair potential in adult bone marrow stem cells

Researchers from the University of Maryland School of Maryland report promising results from using adult stem cells from bone marrow in mice to help create tissue cells of other organs, such as the heart, brain and pancreas - a scientific step they hope may lead to potential new ways to replace cells lost in diseases such as diabetes, Parkinson's or Alzheimer's.
