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 ...
They are one of the triggers of intracellular signal transduction cascades. [1] Examples of second messenger molecules include cyclic AMP, cyclic GMP, inositol triphosphate, diacylglycerol, and calcium. [2] First messengers are extracellular factors, often hormones or neurotransmitters, such as epinephrine, growth hormone, and serotonin.
The entire set of cell changes induced by receptor activation is called a signal transduction mechanism or pathway. [44] Key components of a signal transduction pathway (MAPK/ERK pathway shown) A more complex signal transduction pathway is the MAPK/ERK pathway, which involves changes of protein–protein interactions inside the cell, induced by ...
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 ...

Activity at an axon terminal: Neuron A is transmitting a signal at the axon terminal to neuron B (receiving). Features: 1. Mitochondrion. 2. synaptic vesicle with neurotransmitters. 3. Autoreceptor. 4. Synapse with neurotransmitter released . 5. Postsynaptic receptors activated by neurotransmitter (induction of a postsynaptic potential). 6.
There are two principal signal transduction pathways involving the G-protein coupled receptors: the cAMP signaling pathway and the phosphatidylinositol signaling pathway. [17] Both are mediated via G protein activation. The G-protein is a trimeric protein, with three subunits designated as α, β, and γ.
This can be seen in signal transduction of hormone messages. A signaling pathway begins at the cell surface where a hormone or protein binds to a receptor at the extracellular matrix. The interactions between the molecule and receptor cause a conformational change at the receptor, which activates multiple enzymes or proteins.
