cell signaling

Using a transgenic fruit fly model, researchers demonstrate how epithelial barriers are maintained in living organisms despite high levels of cell turnover and death.

Conservation of structures and functions between single-celled fungi and human cells allow researchers to probe the brain.

Researchers have identified specific cells and neuropeptides involved in mediating the sneeze response in mice exposed to allergens or chemical irritants such as capsaicin.

The single-celled fungus allows researchers to study Alzheimer’s, Parkinson’s, ALS and other brain diseases with unparalleled speed and scale.

A mouse study identifies the brain regions and specific signaling factors that regulate the sneeze response.

Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?

Prior to a 2019 preprint, “glycoRNAs” weren’t known to exist. Now, the researchers who found them say they’re on lots of cells and may play a role in immune signaling.

Corticosterone interferes with signaling in the skin that normally activates hair follicle stem cells, possibly explaining the link between stress and hair loss.

Recent insights, such as the recognition that disseminated cancer cells can lie dormant for years before seeding secondary tumors, suggest novel strategies for fighting metastatic disease.

In two independent studies, researchers find that the organelle is responsible for a switch that allows cells to start moving when they’re squeezed.

Human embryonic stem cells differentiate and organize themselves on a chip.

Numerous cellular changes underlie the decline of muscle mass and strength in the elderly.

An entrepreneurial attitude helped this Vienna-based researcher begin to unravel the complex receptor network that Arabidopsis uses to develop and defend itself.
