receptor

The mechanism is chemical/physical, though, and depends on the absorption spectrum of a certain pigment molecule for each type of receptor.

Also, a positron emission tomography (PET) study7 showed that SAD is associated with reduced serotonin 1A receptor binding.

What this team did discover is a type of receptor in these cells that can trigger this constriction.

For instance, if the medium-wavelength receptor's curve is shifted downward to further overlap the long-wavelength receptor's curve, reddish colors will seem more green and bluish colors will seem less green.

Another recent breakthrough method, called CAR-T cell therapy (chimeric antigen receptor t-cells) also activates the immune system against cancer.

It acts on the same receptor as Baclofen, a prescription drug that's used to relieve muscle spasms and spasticity.

Current evidence seems to indicate the problem is blood glucose levels remaining elevated (despite elevated insulin); this happens because there is a limit to the rate of receptor mediated transport.

Other people lack one color receptor type entirely, and thus have only two-axis color perception instead of the normal three.

Colorblindness is a catchall term for defects in one or more type of light receptor.

If each optical receptor had a narrow acceptance window (the way that individual atoms absorb), there would be gaps in the rainbow.

Some types of cancer secrete molecules that activate this receptor, inhibiting the immune cells.

There are decades of successful pharmacological research based on receptor targets, signaling pathways, etc.

PD-1 (programmed cell death 1) is a receptor on immune cells like T cells that tells these immune cells to "stand down"/go inactive.
