In experiments on mice, researchers tracked brain levels of cell-signaling protein molecules called cytokines, which are boosted by SSRIs, and found they were counteracted by anti-inflammatory drugs.

Dynamic protein phosphorylation is a key cellular signaling mechanism by which a broad spectrum of cellular processes is regulated.

Calcium is a universal signaling molecule involved in many cellular functions such as cell motility, metabolism, protein modification, protein folding, and apoptosis.
