Vital molecular step in cell migration

A vital molecular step in cell migration, the movement of cells within the body during growth, tissue repair and the body's immune response to invading pathogens, has been demonstrated by researchers in the University of California, San Diego (UCSD) School of Medicine.

Genome in gut bacterium key to intestinal health

A bacterium that lives in the human gut adaptively shifts more than a quarter of its genes into high gear when its host's diet changes from sugar to complex carbohydrates.

New therapy for treating cat allergies looks promising

Andrew Saxon, M.D., and a team of researchers at University of California, Los Angeles (UCLA) have found that a molecule designed to block cat allergies can prevent allergic reactions in laboratory mice and was also successful when tested on human cells in a test tube.

Hope of new treatments for liver damage

There is currently no cure for liver cirrhosis and a patient's only hope of survival is to receive a liver transplant.

New insights into Pemphigus

Pemphigus is a deadly skin blistering disease that occurs when patients' produce antibodies that attack proteins in their own cells – called autoantibodies.

Risky surgery not always necessary to treat cervical disease

Revolutionary advancements in the treatment options for diseases associated with human papillomavirus (HPV) now include nonsurgical options such as chemoprevention and vaccines. A review of these methods is published in the latest issue of the International Journal of Gynecological Cancer.

NIAID investigates safety of H5N1 avian influenza vaccine

Fast-track recruitment has begun for a trial to investigate the safety of a vaccine against H5N1 avian influenza, the National Institute of Allergy and Infectious Diseases (NIAID) announced today.

Process for disposal of dying neutrophils actively linked to neutrophil production

New research identifies a critical inhibitory step that is a key component of the feedback circuit regulating the balance between neutrophil production and destruction.

How does the body keep the number of neutrophils produced constant in the blood?

Every day, the human body manufactures and destroys about 100 billion neutrophils- the most common type of white blood cell and one of the most highly-produced cells. Neutrophils live about eight hours, are bacteria-eaters and are a key component of the immune system. Without them, the body can be subject to life-threatening infection.

Scientists have found genetic regions that, when defective, allow the immune system to attack the pancreas

Scientists at Joslin Diabetes Center have found genetic regions that, when defective, allow the immune system to attack the pancreas -- the first in a series of mis-steps that lead to type 1 diabetes. Armed with these findings, published yesterday, March 22, in the journal Immunity, the researchers are now trying to hone in on the exact genes involved, in mice and in human patients.

Discovery that sheds new light upon the growth and development of human natural killer (NK) cells

Scientists here have made a major discovery that sheds new light upon the growth and development of human natural killer (NK) cells, powerful but somewhat mysterious components of the body’s immune system that are the first line of defense against cancer and infectious diseases.

No serious adverse events found with next-generation smallpox vaccine

Interim data from a phase I/II clinical trial of a next-generation vaccine for smallpox suggest that the vaccine may provide immunity and thus far the trial has been without any serious adverse events.

Novel method of testing exhaled breath to detect infection

Researchers from Johns Hopkins University are developing a novel method of testing exhaled breath to detect infection rapidly after potential exposure to a biological warfare agent. They report their findings today at the 2005 ASM Biodefense Research Meeting.

Genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma

The genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma. This finding, from investigators at St. Jude Children's Research Hospital, is published in the current issue of Molecular Cell Biology (MCB).

Donor age has no affect on long-term liver transplant survival

A new study on the effect of donor age on survival and recurrence of hepatitis C after liver transplantation found that it influenced short-term survival, but had no long-term effect.

Alcohol relapse adversely affects liver transplant survival

A new study on how alcohol relapse affects survival rates after liver transplants found that it adversely affected survival rates only after 10 years. The decrease in survival rates may, however, be due to other alcohol-related diseases.

Structure of key protein in innate immune response

In a report published in the Journal of Biological Chemistry, scientists in Korea announced their elucidation of three-dimensional structure of CD14 and showed how it is perfectly suited to bind to certain bacterial products.

Drug-resistant bacteria MRSA a growing threat

Infectious diseases researchers at Vanderbilt University Medical Center are noticing a significant increase in the number of infections due to Methicillin-Resistant Staphylococcus Aureus (MRSA) and the number of asymptomatic individuals who harbor the organism in their bodies.

Genomic analysis may one day be a primary diagnostic tool for physicians deciding on a course of treatment for trauma

The researchers showed that state-of-the-art techniques for rapidly analyzing changes in activity of all human genes will likely produce useful insights into the health of critically ill patients. The findings, which are available online and will be published in the March 29 issue of the Proceedings of the National Academy of Sciences, make it possible for physicians to begin answering important questions about critical care through genomic analysis.
