Blood Test Shows Statistically Significant Association With Alzheimer's Disease (AD), May Predict Conversion Of Mild Cognitive Impairment To AD
Dr. Zsuzsanna Nagy of the University of Birmingham presented data from a clinical study, funded by Cytox Limited, demonstrating that a simple blood-based biomarker discriminated between patients with Alzheimer"s disease (AD) and control subjects. The findings were statistically highly significant, and the test discriminated between the two groups with 80% sensitivity and 80% specificity. The results also showed that 40% of the mild cognitive impairment (MCI) patients tested had the same test results as AD patients. Follow up study of MCI patients enrolled in an earlier study found that the test allowed early identification of those MCI patients who later developed dementia. The results were presented at the 2009 Alzheimer"s Association International Conference on Alzheimer"s Disease (ICAD 2009), held in Vienna, Austria.

Researchers Plan To Target Immune Cells Responsible For Eluding Antiretroviral Treatment
Certain human immune cells known as macrophages are composed of hybrid HIV strains that elude treatment and antiretroviral drugs, according to a new study by researchers from the University of Florida and other institutions, the Gainesville Sun reports. For the study, researchers examined tissue from HIV-positive people and discovered that as much as half of the macrophages present were hybrids, made from genetic material from several HIV viruses that when combined formed new HIV strains. Marco Salemi -- assistant professor of pathology, immunology and laboratory medicine at the University of Florida"s College of Medicine -- said that macrophages likely make HIV more aggressive over time, adding, "If we want to eradicate HIV, we need to find a way to actually target the virus specifically infecting the macrophages." According to the Sun, current research and treatment target T-cells, and although antiretrovirals are effective at blocking infection from new cells and lowering viral loads, they are unable to reduce the viral level in an HIV-positive person to zero. The Sun notes that macrophages can be targeted by HIV multiple times, and once they are infected, they can live for months, unlike T-cells. The team of researchers, led by Michael McGrath of the University of California - San Francisco, is developing macrophage-targeting drugs through a grant from the National Institute of Mental Health, the Sun reports (Chun, Gainesville Sun, 5/28).
