Serotonin pathways are thought to modulate eating, both the amount as well as the motor processes associated with eating. The serotonergic projections into the hypothalamus are thought to be particularly relevant, and an increase in serotonergic signaling is thought to generally decrease food consumption (evidenced by fenfluramine , however ...
The Journal of Receptors and Signal Transduction is a peer-reviewed scientific journal that publishes laboratory and clinical studies, reviews, and brief communications on biological receptors and associated signal transduction pathways for ligands involved in the regulation of central and peripheral tissues and cells.
With the advent of computational biology, the analysis of signaling pathways and networks has become an essential tool to understand cellular functions and disease, including signaling rewiring mechanisms underlying responses to acquired drug resistance. [6] Simplified representation of major signal transduction pathways in mammals.
Serotonylation is the process by which serotonin effects the exocytosis of alpha-granules from platelets (also known as thrombocytes). [1] This involves the serotonylation of small GTPases such as Rab4 and RhoA. It has been suggested that "further understanding of the specific hormonal role of 5-HT in hemostasis and thrombosis is important to ...
In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway
The phosphoinositol signaling pathway. Binding of a primary messenger to these receptors results in conformational change of the receptor. The α subunit, with the help of guanine nucleotide exchange factors (GEFS), releases GDP, and binds GTP, resulting in the dissociation of the subunit and subsequent activation. [9]

One notable example of functional selectivity occurs with the 5-HT 2A receptor, as well as the 5-HT 2C receptor. Serotonin, the main endogenous ligand of 5-HT receptors, is a functionally selective agonist at this receptor, activating phospholipase C (which leads to inositol triphosphate accumulation), but does not activate phospholipase A2, which would result in arachidonic acid signaling.
