Glycome shift in epidermal stem cells could serve as potential biomarker of aging

Age shows nowhere better than on the skin. The ravages of time on skin and the epidermal stem cells that differentiate to replenish its outer layer have been hypothesized, but there has been no method to evaluate their aging at the molecular level.

How immune cells switch to attack mode

Unraveling a key motif: The T lymphocytes of the immune system work to destroy infected cells or cancer cells. To do so, they have to identify the threat: Molecules perceived as foreign - so-called antigens - bind to the T-cell receptor on the T cell surface.

Novel nanospectroscopy measures biomolecular changes induced by drugs in human cells

Synchrotron InfraRed Nanospectroscopy has been used for the first time to measure biomolecular changes induced by a drug (amiodarone) within human cells (macrophages) and localized at 100 nanometre scale, i.e. two orders of magnitude smaller than the IR wavelength used as probe.

Study reveals how two key neural circuits control social preference

Some individuals love meeting new people, while others abhor the idea. For individuals with conditions such as autism, unfamiliar social interactions can produce negative emotions such as fear and anxiety. A new study from Scripps Research reveals how two key neural circuits dictate the choice between social approach and avoidance.
