Stem Cells Lurking in Tumors Can Resist Treatment

March 16, 2015 10:27 am | by Michael C. Purdy, Washington University in St. Louis | News | Comments

Scientists are eager to make use of stem cells’ extraordinary power to transform into nearly any kind of cell, but that ability also is cause for concern in cancer treatment. Malignant tumors contain stem cells, prompting worries among medical experts that the cells’ transformative powers help cancers escape treatment.

First Look at Hospitalized Ebola Survivors' Immune Cells Could Guide Vaccine Design

March 10, 2015 10:29 am | by Emory University | News | Comments

In the ongoing Ebola outbreak in West Africa, whose death toll is approaching 10,000, little information has been available about how the human immune response unfolds after infection. Researchers have now obtained a first look at the immune responses in four Ebola virus disease survivors who received care at Emory University Hospital in 2014, by closely examining their T cells and B cells during the acute phase of the disease.

Protein in the Brain Can 'Put the Brakes' On Binge Drinking

March 10, 2015 10:20 am | by UNC | News | Comments

A new study led by UNC researchers identifies both where in the brain and how a protein in the brain, called Neuropeptide Y or NPY, can act to suppress binge alcohol drinking. These findings suggest that restoring NPY may be useful for treating alcohol use disorders and may also protect some individuals from becoming alcohol dependent.
