Tamsulosin is relatively selective for α-adrenergic receptors, which are mainly present in the prostate.

Numerous other enzyme activities have been reported among the 300 known coactivators for nuclear receptors.

Naloxone has an extremely high affinity for μ-opioid receptors in the central nervous system.

In fact, buprenorphine has a higher affinity for opioid receptors than almost all opioids including heroin.

Its eyes were too small for visual receptors, and they did not glow.

For cold receptors their firing rate increases during cooling and decreases during warming.

We know this because biologists have found genes coding for toll-like receptors in many different metazoans.

The other values correspond to their affinity for various receptors.

It does not appear to have any significant affinity for the D or α-adrenergic receptors.

The ligands for receptors are as diverse as their receptors.
