The double face of fentanyl: the neuronal basis of opioid addiction

Life Sciences - May 22
Life Sciences

Scientists from the University of Geneva have discovered that fentanyl leads to the activation of two distinct cell populations in the brain, first when the drug is taken and then during withdrawal, suggesting a novel model for opioid addiction. Fentanyl is a particularly powerful synthetic opioid. Diverted from its original medical use, it has become a deadly drug responsible for three-quarters of overdose deaths in the United States.

How immune cells recognize the abnormal metabolism of cancer cells

Health

When cells become tumor cells, their metabolism changes fundamentally. Researchers at the University of Basel and the University Hospital Basel have now demonstrated that this change leaves traces that could provide targets for cancer immunotherapies.
