Better understanding of immune response to HIV infection

The "exhaustion" of immune cells that target HIV appears to result from chronic exposure to the virus, specifically exposure to the particular protein segments targeted by the pathogen-killing HIV-specific CD8 T cells.

Newly identified protein called BILBO1 fatal to Trypanosoma brucei

Trypanosoma brucei is a pathogen that causes epidemics of human and animal sleeping sickness in central and Southern Africa, a disease that is fatal if untreated. A new paper published this week in the open-access journal PLoS Biology investigates the formation of a trypanosome structure called the Flagellar Pocket (FP).

New saliva-based HIV test gives results in 20 minutes!

The usual waiting period for the results of a HIV test can seem like an eternity, especially in emergency situations where results are needed immediately. Also it requires a blood sample, which is invasive and often painful. Recognizing the urgent need for a faster and less invasive diagnostic method, Dr. Nitika Pant Pai, from Marina Klein's research team at the MUHC has just finished testing a new saliva-based test that gives results in approximately 20 minutes! She describes her findings in an article that will appear in the May 6th, 2008 issue of PLoS Medicine.

Stanford researchers synthesize new agents to flush HIV out of hiding

Any hunter will tell you that when your quarry goes into hiding, you have to flush it out to get a good shot at it. Such is the case with HIV, the virus that causes AIDS.

Obesity and heart failure risk

Heart specialists at Johns Hopkins and elsewhere report what is believed to be the first wide-scale evidence linking severe overweight to prolonged inflammation of heart tissue and the subsequent damage leading to failure of the body's blood-pumping organ.

Mothers and offspring can share cells throughout life - with positive and negative effects

Cutting the umbilical cord doesn't necessarily sever the physical link between mother and child. Many cells pass back and forth between the mother and fetus during pregnancy and can be detected in the tissues and organs of both even decades later. This mixing of cells from two genetically distinct individuals is called microchimerism. The phenomenon is the focus of an increasing number of scientists who wonder what role these cells play in the body.

Discovery of quick method for making human monoclonal antibodies against flu

Human monoclonal antibodies (mAbs) - highly specific, identical, infection-fighting proteins produced in large quantities in the lab in cell lines that are derived from a single antibody-producing cell - against influenza can be rapidly produced in the lab, according to a new report from scientists supported by the National Institutes of Health (NIH).

Study explains why steroid therapy for sinusitis and asthma loses its punch over time

Scientists at Johns Hopkins have outlined a new path for potential therapies to combat inflammation associated with sinusitis and asthma based on a new understanding of the body's earliest immune response in the nose and sinus cavities.

Human protein may offer novel target for blocking HIV infection

A research group supported by the National Institutes of Health (NIH) has uncovered a new route for attacking the human immunodeficiency virus (HIV) that may offer a way to circumvent problems with drug resistance. In findings published today in the online edition of the Proceedings of the National Academy of Sciences, the researchers report that they have blocked HIV infection in the test tube by inactivating a human protein expressed in key immune cells.
