Later, scientists tested these synthetic prostaglandins in cells and animals and verified that they functioned like the naturally occurring molecules, validating the proposed structures.

For instance, neurotransmitters are a class of short-range signaling molecules that travel across the tiny spaces between adjacent neurons or between neurons and muscle cells. Other signaling ...

Biological cells have many vital functions in the organism. For example, they produce proteins, carbohydrates and fats. But ...

“Mirror bacteria” could evade people’s immune systems, they suggest, causing deadly infections. Such infections could also ...

A team of researchers used a new technique, called high-resolution template matching, or HRTM, to uncover in unprecedented detail the movement of ribosomes -- the molecular structures that synthesize ...

Neuroscience is the science of the nervous system, from molecules and cells to the relationship between the brain and behavior. SLU’s College of Arts and Sciences provides students with a rigorous ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

A new technology uses engineered T cells that act as immune “referees” to soothe overreacting immune responses. They also can ...

Osmosis refers to the movement of water molecules only. The slideshow shows ... In pure water, the cell contents (the cytoplasm and vacuole) push against the cell wall and the cell becomes turgid ...

Selectins are a family of cell adhesion molecules that participate in the early phases of leukocyte–endothelium interactions. They are required for the trafficking of innate immune system cells, T ...

AMIGO defines a novel gene family with three closely related members (AMIGO, AMIGO 2, and AMIGO 3) that belong to both LRR (leucine-rich repeat) and Ig (immunoglobulin) superfamilies of cell surface .
