Researchers find new signaling systems in human cells

One-third of all approved drugs target the same family of receptors: the G-protein-coupled receptors (GPCRs). Now, researchers from the University of Copenhagen, along with two American labs, have expanded the known network ...

EphA4 -- the molecular transformer

(PhysOrg.com) -- EphA4 is a protein which is attached to the surfaces of many types of human cells and plays a role in a wide range of biological processes. EphA4 functions by binding to ephrin ligands, cell surface proteins ...

Study uncovers new hurdle for developing immunotherapies

The body's immune system is a valiant weapon against disease, and harnessing its power through a technique called immunotherapy is at the forefront of current research to treat cancer and other diseases.

Grafting olfactory receptors onto nanotubes

(PhysOrg.com) -- Penn researchers have helped develop a nanotech device that combines carbon nanotubes with olfactory receptor proteins, the cell components in the nose that detect odors.

How plants measure their carbon dioxide uptake

When water is scarce, plants can close their pores to prevent losing too much water. This allows them to survive even longer periods of drought, but with the majority of pores closed, carbon dioxide uptake is also limited, ...
