1.8-OH-DPAT acts on both 5-HT1A and 5-HT7 receptors to induce hypothermia in rodents.
Hedlund PB;Kelly L;Mazur C;Lovenberg T;Sutcliffe JG;Bonaventure P Eur J Pharmacol. 2004 Mar 8;487(1-3):125-32.
Studies using selective drugs and knockout mice have demonstrated that the 5-HT(7) receptor plays an instrumental role in serotonin-induced hypothermia. There is also evidence supporting an involvement of the 5-HT(1A) receptor, although mainly from studies using 8-hydroxy-2(di-n-propylamino)tetralin (8-OH-DPAT), a 5-HT(1A/7) receptor agonist. Here we studied the effects of 8-OH-DPAT and selective antagonists for the 5-HT(1A) and 5-HT(7) receptors on body temperature in rats, wild-type (5-HT(7)(+/+)) mice and knockout (5-HT(7)(-/-)) mice. At lower doses (0.3-0.6 mg/kg, i.p.), 8-OH-DPAT decreased body temperature in 5-HT(7)(+/+) mice but not in 5-HT(7)(-/-) mice. At a higher dose (1 mg/kg, i.p.) 8-OH-DPAT induced hypothermia in both 5-HT(7)(-/-) and 5-HT(7)(+/+) mice. The 5-HT(1A) receptor antagonist (S)-N-tert-butyl-3-(4-(2-methoxyphenyl)piperazine-1-yl)-2-phenylpropanamide (WAY-100135) (10 mg/kg, i.p.) inhibited the effect of 8-OH-DPAT at all doses in rats and mice. In 5-HT(7)(+/+) mice the selective 5-HT(7) receptor antagonist (R)-3-(2-(2-(4-methylpiperidin-1-yl)-ethyl)pyrrolidine-1-sulfonyl)phenol (SB-269970) (10 mg/kg, i.p.) fully inhibited the hypothermia induced by 0.3 mg/kg 8-OH-DPAT, but not that of higher doses.
2.Peripheral and spinal 5-HT receptors participate in the pronociceptive and antinociceptive effects of fluoxetine in rats.
Cervantes-Durán C;Rocha-González HI;Granados-Soto V Neuroscience. 2013 Nov 12;252:396-409. doi: 10.1016/j.neuroscience.2013.08.022. Epub 2013 Aug 27.
The role of 5-HT receptors in fluoxetine-induced nociception and antinociception in rats was assessed. Formalin produced a typical pattern of flinching and licking/lifting behaviors. Local peripheral ipsilateral, but not contralateral, pre-treatment with fluoxetine (0.3-3 nmol/paw) increased in a dose-dependent fashion 0.5% formalin-induced nociception. In contrast, intrathecal pretreatment with fluoxetine (0.3-3 nmol/rat) prevented nociception induced by formalin. The peripheral pronociceptive effect of fluoxetine was prevented by the 5-HT2A (ketanserin, 3-10 pmol/paw), 5-HT2B (3-(2-[4-(4-fluorobenzoyl)-1-piperidinyl]ethyl)-2,4(1H,3H)-quinazolinedione(+) tartrate, RS-127445, 3-10 pmol/paw), 5-HT2C (8-[5-(2,4-dimethoxy-5-(4-trifluoromethylphenylsulphonamido) phenyl-5-oxopentyl]1,3,8-triazaspiro[4.5] decane-2,4-dione hydrochloride, RS-102221, 3-10 pmol/paw), 5-HT3 (ondansetron, 3-10 nmol/paw), 5-HT4 ([1-[2-methylsulphonylamino ethyl]-4-piperidinyl]methyl 1-methyl-1H-indole-3-carboxylate, GR-113808, 3-100 fmol/paw), 5-HT6 (4-iodo-N-[4-methoxy-3-(4-methyl-1-piperazinyl)phenyl]benzene-sulfonamide hydrochloride, SB-258585, 3-10 pmol/paw) and 5-HT7 ((R)-3-(2-(2-(4-methylpiperidin-1-yl) ethyl) pyrrolidine-1-sulfonyl) phenol hydrochloride, SB-269970, 0.
3.Pharmacological characterization of 5-Hydroxytryptamine-receptor subtypes in circular muscle from the rat stomach.
Komada T;Yano S Biol Pharm Bull. 2007 Mar;30(3):508-13.
5-Hydroxytryptamine (5-HT) modulates gastric motility and gastric emptying via a variety of 5-HT receptor subtypes. However, regional and functional differences among 5-HT receptor subtypes in the rat stomach are not fully investigated. Thus, we aimed to characterize 5-HT receptor subtypes involved in the 5-HT-induced contractions in the isolated antral, corporal and fundic circular muscles of the rat stomach by measuring the contractile force. 5-HT induced concentration-dependent contractions in the antrum, corpus and fundus. 5-HT-induced antral contractions were partly blocked by atropine and enhanced by tetrodotoxin (TTX). Neither atropine nor TTX affected the corporal or the fundic contractions to 5-HT. In the antrum, 5-HT-induced contractions were inhibited by methysergide, tended to be inhibited by ketanserin, enhanced by SB-203186, but were not affected by WAY-100635, GR127935, RS-127445, ondansetron, or SB-269970. In the corpus, 5-HT-induced contractions were inhibited by ketanserin or methysergide. In the fundus, 5-HT-induced contractions were blocked by methysergide or RS-127445, but were enhanced by cinanserin or SB-203186. It is thus concluded that contractile responses to 5-HT in the antrum are mediated by 5-HT receptors on both smooth muscle and neurons whilst in the corpus and fundus responses are mainly mediated by 5-HT receptors on smooth muscle.
