Somatostatin, a signaling molecule produced by many inhibitory neurons in the brain, broadly dampens communication among a variety of cell types in the prefrontal cortex and promotes exploratory and ...

WEST LAFAYETTE, Ind. - A Purdue University study shows that Notch signaling, a key biological pathway tied to development and cell communication, also plays an important role in the onset of obesity ...

Navigating the world is no mean feat, especially when the world pushes back. For instance, airflow hitting a fly on its right side can, after a turn, become a headwind. To stay on course, the fly's ...

Can eating fat be good for us? Some fatty acid molecules actually play a crucial role in maintaining our health and cellular functions. By the early twentieth century, scientists and doctors widely ...

Brain cells grow faster in children with some forms of autism due to distinct changes in core cell signaling patterns, according to research from the laboratory of Anthony Wynshaw-Boris, MD, PhD, ...

Although USP22 has been associated with IFN signaling and ISG expression upon viral infections, the mechanisms underlying USP22 priming of PRRs and IFN signaling in native, uninfected environments ...

Now UAB researchers, led by Guanlan Xu, Ph.D., and Shalev drilled down further into the mechanism underlying verapamil’s beneficial effect. In a paper published in Diabetes, they show that, in Type 1 ...

Scientists at EPFL have created a scalable 3D organoid model that captures key features of early limb development, revealing how a specialized signaling center shapes both cell identity and tissue ...

To navigate, the brain must convert changing sensations into a map-like sense of the world, which remains stable as the body moves. A new study finds that the fly brain sometimes performs the ...
