A receptor acts like a switch to turn on a cell's genetic activity.

A receptors are widely distributed, and act to inhibit calcium uptake.

The hope is that these receptors will act like decoys, sopping up the cytokines and preventing them from attaching to other cells in the body.

Metabotropic receptors, which are also called G-protein-coupled receptors, act on an ion channel through the intracellular signaling of a molecule called a G protein.

These two receptors act through different pathways to contribute to endothelial cell proliferation and migration, and formation of tubular structures.

This receptor acts as a sort of gate, controlling the flow of Cl- and HCO3- anions into neurons.

These receptors may also act to suppress the immune system under certain conditions.

Neurotransmitters bind to proteins on the surfaces of cells called receptors; receptors act like molecular switches and turn production of chemicals and proteins on and off.

In some cases, these receptors act as analgesics, as P2Y1 has the ability to inhibit the action of P2X3.

Each receptor accepts all the light reaching it but acts as a unit, representing a single location in visual space.
