Modern views on an ancient chemical: serotonin effects on cell proliferation, maturation, and apoptosis.
Brain Res Bull 2001 Nov 15;56(5):413-24
"Evolutionarily, serotonin existed in plants even before the appearance of animals. Indeed, serotonin may be tied to the evolution of life itself, particularly through the role of tryptophan, its precursor molecule. Tryptophan is an indole-based, essential amino acid which is unique in its light-absorbing properties. In plants, tryptophan-based compounds capture light energy for use in metabolism of glucose and the generation of oxygen and reduced cofactors. Tryptophan, oxygen, and reduced cofactors combine to form serotonin. Serotonin-like molecules direct the growth of light-capturing structures towards the source of light. This morphogenic property also occurs in animal cells, in which serotonin alters the cytoskeleton of cells and thus influences the formation of contacts. In addition, serotonin regulates cell proliferation, migration and maturation in a variety of cell types, including lung, kidney, endothelial cells, mast cells, neurons and astrocytes). In brain, serotonin has interactions with seven families of receptors, numbering at least 14 distinct proteins. Of these, two receptors are important for the purposes of this review. These are the 5-HT1A and 5-HT2A receptors, which in fact have opposing functions in a variety of cellular and behavioral processes. The 5-HT1A receptor develops early in the CNS and is associated with secretion of S-100beta from astrocytes and reduction of c-AMP levels in neurons. These actions provide intracellular stability for the cytoskeleton and result in cell differentiation and cessation of proliferation. Clinically, 5-HT1A receptor drugs decrease brain activity and act as anxiolytics. The 5-HT2A receptor develops more slowly and is associated with glycogenolysis in astrocytes and increased Ca(++) availability in neurons. These actions destabilize the internal cytoskeleton and result in cell proliferation, synaptogenesis, and apoptosis. In humans, 5-HT2A receptor drugs produce hallucinations. The dynamic interactions between the 5-HT1A and 5-HT2A receptors and the cytoskeleton may provide important insights into the etiology of brain disorders and provide novel strategies for their treatment."

Evidence for involvement of protein kinases in the regulation of serotonin synthesis and turnover in the mouse brain in vivo.
J Neural Transm 2002 Nov;109(11):1353-63
"Inhibition of cAMP-dependent protein kinase (PKA) with N-[2-methylamino)ethyl]-5-isoquinolinesulfonamide (H-8) almost completely antagonized the increase in 5-HTP accumulation and 5-HIAA/5-HT ratio in hypothalamus induced by NAS-181, a 5-HT(1B) receptor antagonist, but had no effect when the mice were treated with NAS-181 together with WAY-100,635, a selective 5-HT(1A) receptor antagonist. Inhibition of Ca(2+)-calmodulin-dependent protein kinase (CaM kinase II) with the calmodulin antagonist N-(4-aminobutyl)-5-chloro-2-naphtalenesulfonamide (W-13) did not antagonise the effect of NAS-181 alone, but counteracted that evoked by the combined treatment with NAS-181 and WAY-100,635. The results indicate that activation of tryptophan hydroxylase by reducing the tone from terminal 5-HT(1B) receptors involves PKA whereas the depolarisation-induced activation of tryptophan hydroxylase involves CaM kinase II. The increase in the 5-HIAA/5-HT ratio may under the experimental conditions used suggest CaM kinase II-induced phosphorylation of synapsin I resulting in increased 5-HT release." [Abstract]

Selective inhibition of local excitatory synaptic transmission by serotonin through an unconventional receptor in the CA1 region of rat hippocampus
J Physiol (Lond) 2001 534: 141-158
"In the present study we demonstrate a previously undescribed inhibitory action of 5-HT on CA1 excitatory synaptic transmission. This effect is exerted by submicromolar concentrations of 5-HT acting through an unconventional 5-HT receptor apparently located on axon collaterals of CA1 pyramidal neurones."

Multiple Subtypes of Serotonin Receptors Are Expressed in Rat Sensory Neurons in Culture
J Pharmacol Exp Ther 1998 287: 1119-1127
"The presence of 5-HT1B receptors was confirmed by the displacement of [125I]Iodocyanopindolol binding by cyanopindolol with an IC50 of 2.43 ± 0.81 nM. 5-HT1B receptors are the predominant type of serotonin receptors labeled by [3H]5-HT in cultured DRG neurons, representing ~60% of the specific [3H]5-HT binding sites. In addition, 5-HT1D and 5-HT2A receptor binding was also found in these neurons. RT-PCR analysis of RNA isolated from embryonic sensory neurons in culture confirmed the expression of 5-HT1B, 5-HT1D and 5-HT2A receptor mRNA. It also demonstrated the presence of 5-HT1F, 5-HT2C, 5-HT3, 5-HT4, 5-HT5A and 5-HT5B receptor mRNA and the absence of 5-HT1A, 5-HT1E, 5-HT2B, 5-HT6 and 5-HT7 mRNA." [Full Text]

The molecular evolution of G protein-coupled receptors: focus on 5-hydroxytryptamine receptors.
Neuropharmacology 1994 Mar-Apr;33(3-4):319-24
"Phylogenetic comparisons between homologous proteins can provide information on the rates of molecular evolution of the proteins. G protein-coupled receptors are a "superfamily" of proteins which exist in species ranging from yeast to man. Based on an analysis of the percentage of amino acid homology between various species, the rate of molecular evolution of G protein-coupled receptors can be estimated at approx 1% per 10 million years. Based on this assumption, the primordial 5-HT receptor must have evolved more than 700-800 million years ago since the 3 major classes of G protein-coupled 5-HT receptors (i.e. 5-HT1, 5-HT2 and 5-HT6 receptors) are less than 25% homologous. 5-HT5, 5-HT7, 5-HTsnail, 5-HTdro and 5-HT1A receptors differentiated approx 600-700 million years ago, the time period during which vertebrates diverged from invertebrates. The mammalian 5-HT receptor subtypes have differentiated over the past 90 million years. Thus, although a recent flurry of "new" 5-HT receptors have appeared in the literature, the first "primordial" 5-HT receptor evolved over 750 million years ago, a date which likely predates the evolution of muscarinic, dopaminergic and adrenergic receptor systems. This analysis also predicts that a significant number of both mammalian and invertebrate G protein-coupled 5-HT receptor subtypes remain to be identified." [Abstract]
