Stem Cells May Be Able to Fight HIV; Antidepressants Ease Depression in Parkinson

(April 14, 2012 - Insidermedicine)

From California - Scientists have genetically engineered human stem cells to kill HIV, according to a report published in PLoS Pathogens. UCLA researchers engineered human stem cells to fight HIV, testing the cells on a mouse model with HIV. Results showed that CD4 t Cells increased in the blood while levels of HIV in the blood decreased.

From Rochester - A new report published in Neurology examines the use of antidepressant medication in people with Parkinson's disease. Studying over 100 Parkinson's disease patients, researchers found that antidepressant medication eased depression without adversely worsening symptoms of their disease.

And finally from Florida - New research published in online in Nature Communications finds that a fragment of the amyloid precursor protein (APP) can help prevent the formation of amyloid plaques in the brain. The researchers found that this protein fragment, called sAPP-α, interacts with the main protein responsible for converting APP into amyloid-β, the main component of brian plaques.
