Serotonin is a biochemical compound that contributes to a variety of important biological functions, including the regulation of mood and emotions. Certain brain cells make serotonin and release it ...

that molecules had to cross the cell’s outer membrane in order to bind to them, he says. The researchers tested this hypothesis with a series of experiments. By tagging the serotonin 2A receptor with ...

5-hydroxytrophan transporter, 5-HTT, is the membrane transporter for serotonin and uses an ion gradient for coupled reuptake. In the gut, 5-HTT is located in epithelial cells, and its function is ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

Cell membrane proteins hide secret gateways that can be used to modify cell behavior. This has been demonstrated in a study ...

On the biochemical front, researchers point out that cell membranes are made up partly of omega-3s. It is possible that increasing the omega-3 levels makes it easier for serotonin -- a chemical ...

Long-term fasting in 24-hour cycles increases the sex drive of male mice by lowering the concentration of the neurotransmitter serotonin in the brain. Cell membrane proteins hide secret gateways ...
