Other signaling molecules must move much farther ... In fact, there are hundreds of receptor types found in cells, and varying cell types have different populations of receptors.

Identifying these different contributing signaling molecules ultimately required ... Virtually every type of cell (other than red blood cells) produces one or more of these signaling molecules.

Stanford Medicine scientists are generating a periodic table of sorts for psychiatric disorders, providing a better understanding of these conditions and paving the way toward targeted treatment.
