“…Previous experimental studies have reported a noticeable dose-dependent increase of TH in the gills of M. galloprovincialis exposed to 0.1, 1, 10 μg Cr(VI) L − 1 animal −1 for 96 h (Ciacci et al, 2012). The increase in TH may result in the enhancement of dopaminergic neurotransmission that has an inhibitory effect on lateral ciliary activity of mussel gills (Carroll and Catapane, 2007). Zhu et al (2005) demonstrated that tyrosine and tyramine may augment endogenous ganglionic morphine and dopamine levels in Mytilus edulis under in vitro and in vivo experiments, with the involvement of CYP2D6 and TH in the process, resulting in a cilioinhibitory effect.…”

“…The rise of 5-HT 3 R could be related to an adaptive response mediated by paracrine signaling activities in order to recover a regular physiological activity in gills. Indeed, it has been reported that gill epithelial cells containing the lateral cilia present 5-HT receptors to increasing the ciliary beating rate, if activated (Carroll and Catapane, 2007). Fabbri and Capuzzo (2006), after exposing mussel M. galloprovincialis to Cr(VI) and Cu(II), found increased 5-HTstimulated adenylate cyclase activity in vivo, and suggested the possibility that metal accumulation in mussel gills might induce the overexpression of 5-HT receptors.…”

“…Gill activity is regulated by sympathetic and parasympathetic innervations of the autonomic nervous system running through the branchial connective tissue (Catapane et al, 1974), with various neurotransmitters participating in regulation of ciliary beating (Stefano, 1990). Serotonin, or 5-hydroxytryptamine (5-HT), involved in the serotonergic system, plays a cilioexcitatory activity in the gills of lamellibranchiates (Gosselin, 1961;Carroll and Catapane, 2007). The molluskan gill contains significant amounts of endogenous 5-HT, which produces prompt, sustained, and reversible stimulation of ciliary beat frequency, and the magnitude of the response is graded over a wide range of 5-HT levels (Gosselin, 1961).…”

“…Dopamine has been shown to be a component inhibitor of lateral cilia activity in all tested bivalve species (Jørgensen, 1976;Malanga, 1974;Carroll and Catapane, 2007); however, it has no effect on latero-frontal cilia (Jørgensen, 1976) and may stimulate the activity of frontal cilia (Malanga, 1975). Dopamine is also known to stimulate glycolysis (Malanga, 1974) and relax catch muscles (Twarog and Cole, 1972).…”

Ammonia excretion in mytilid mussels is facilitated by ciliary beating

The excretion of nitrogenous waste products in the form of ammonia (NH 3 ) and ammonium (NH 4 + ) is a fundamental process in aquatic organisms. For mytilid bivalves, little is known about the mechanisms and sites of excretion. This study investigated the localization and the mechanisms of ammonia excretion in mytilid mussels. An Rh protein was found to be abundantly expressed in the apical cell membrane of the plicate organ, which was previously described as a solely respiratory organ. The Rh protein was also expressed in the gill, although at significantly lower concentrations, but was not detectable in mussel kidney. Furthermore, NH 3 /NH 4 + was not enriched in the urine, suggesting that kidneys are not involved in active NH 3 /NH 4 + excretion. Exposure to elevated seawater pH of 8.5 transiently reduced NH 3 /NH 4 + excretion rates, but they returned to control values following 24 h acclimation. These mussels had increased abundance of V-type H + -ATPase in the apical membranes of plicate organ cells; however, NH 3 /NH 4 + excretion rates were not affected by the V-type H + -ATPase specific inhibitor concanamycin A (100 nmol l −1). In contrast, inhibition of ciliary beating with dopamine and increased seawater viscosity significantly reduced NH 3 excretion rates under control pH (8.0). These results suggest that NH 3 /NH 4 + excretion in mytilid mussels takes place by passive NH 3 diffusion across respiratory epithelia via the Rh protein, facilitated by the water current produced for filter feeding, which prevents accumulation of NH 3 in the boundary layer. This mechanism would be energy efficient for sessile organisms, as they already generate water currents for filter feeding.

“…Serotonin is known to increase activity of different types of cilia in molluscs (Audesirk et al 1979;Beiras and Widdows 1995;Uhler et al 2000 Carroll andCatapane 2007). For example Beiras and Widdows (1995) showed increased swimming activity of M. edulis larvae after exposure to serotonin, which enhanced movement of velar cilia.…”

Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Pseudoalteromonas sp. AMGP1 were tested for their abilities to induce larval settlement. Toxicity effects of each treatment also were simultaneously identified by recording larval mortalities. Results indicate that all chemicals used induced larvae to settle, with acetylcholine being the most effective (~24% at 10 -6 M compared to <2% in control assays). Toxicities of treatment compounds were low at optimal settlement inducing concentrations, except for L-Tryptophan (~32%) and GABA (~59%). Our data suggest that catecholamines (and their precursors) play an important role in the biochemical mechanisms of settlement for A. maoriana. While serotonin precursors did induce low levels of larval settlement at some concentrations, high toxicity responses to 5-HTP at 10 -5 M, combined with complete settlement inhibition indicate A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTthat the mechanism of action may be more complex than can be elucidated in this study. Larval settlement responses to bacterial treatments were low for planktonic and biofilm phases across all three strains, and settlement inhibition was observed when larvae were exposed to biofilm exudates of all bacterial strains. Comparisons of A. maoriana responses to other endemic and worldwide distributed mussel species are provided as a means to highlight potential evolutionary differences in chemoreception mechanisms. Highlights 1.Mussel larval settlement responses were tested with neuroactive compounds amino acids, and bacterial biofilms.2. All chemicals induced larvae to settle, with acetylcholine being the most effective.3. Catecholamines (and their precursors) play an important role in the biochemical mechanisms of settlement for A. maoriana. Settlement responses to serotonin precursors require further investigationsince there were high toxicity responses.5. Larval settlement responses to bacterial treatments were low for planktonic and biofilm phases, and exposure to biofilm exudates resulted in settlement inhibition.
