Imiuwa ME, Baynes A, Routledge EJ. Understanding target-specific effects of antidepressant drug pollution on molluscs: A systematic review protocol. PLoS One 2023; 18:e0287582. [PMID: 37368915 DOI: 10.1371/journal.pone.0287582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Accepted: 06/06/2023] [Indexed: 06/29/2023] Open
Abstract
BACKGROUND The environmental prevalence of widely prescribed human pharmaceuticals that target key evolutionary conserved biomolecules present across phyla is concerning. Antidepressants, one of the most widely consumed pharmaceuticals globally, have been developed to target biomolecules modulating monoaminergic neurotransmission, thus interfering with the endogenous regulation of multiple key neurophysiological processes. Furthermore, rising prescription and consumption rates of antidepressants caused by the burgeoning incidence of depression is consistent with increasing reports of antidepressant detection in aquatic environments worldwide. Consequently, there are growing concerns that long-term exposure to environmental levels of antidepressants may cause adverse drug target-specific effects on non-target aquatic organisms. While these concerns have resulted in a considerable body of research addressing a range of toxicological endpoints, drug target-specific effects of environmental levels of different classes of antidepressants in non-target aquatic organisms remain to be understood. Interestingly, evidence suggests that molluscs may be more vulnerable to the effects of antidepressants than any other animal phylum, making them invaluable in understanding the effects of antidepressants on wildlife. Here, a protocol for the systematic review of literature to understand drug target-specific effects of environmental levels of different classes of antidepressants on aquatic molluscs is described. The study will provide critical insight needed to understand and characterize effects of antidepressants relevant to regulatory risk assessment decision-making, and/or direct future research efforts. METHODS The systematic review will be conducted in line with the guidelines by the Collaboration for Environmental Evidence (CEE). A literature search on Scopus, Web of Science, PubMed, as well as grey literature databases, will be carried out. Using predefined criteria, study selection, critical appraisal and data extraction will be done by multiple reviewers with a web-based evidence synthesis platform. A narrative synthesis of outcomes of selected studies will be presented. The protocol has been registered in the Open Science Framework (OSF) registry with the registration DOI: 10.17605/OSF.IO/P4H8W.

Abstract
Fungi produce diverse metabolites that can have antimicrobial, antifungal, antifeedant, or psychoactive properties. Among these metabolites are the tryptamine-derived compounds psilocybin, its precursors, and natural derivatives (collectively referred to as psiloids), which have played significant roles in human society and culture. The high allocation of nitrogen to psiloids in mushrooms, along with evidence of convergent evolution and horizontal transfer of psilocybin genes, suggest they provide a selective benefit to some fungi. However, no precise ecological roles of psilocybin have been experimentally determined. The structural and functional similarities of psiloids to serotonin, an essential neurotransmitter in animals, suggest that they may enhance the fitness of fungi through interference with serotonergic processes. However, other ecological mechanisms of psiloids have been proposed. Here, we review the literature pertinent to psilocybin ecology and propose potential adaptive advantages psiloids may confer to fungi.

The Role of Serotonin in the Influence of Intense Locomotion on the Behavior Under Uncertainty in the Mollusk Lymnaea stagnalis. Front Physiol 2020; 11:221. [PMID: 32256385 PMCID: PMC7091490 DOI: 10.3389/fphys.2020.00221] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Accepted: 02/26/2020] [Indexed: 12/24/2022] Open
Abstract
The role of serotonin in the immediate and delayed influence of physical exercise on brain functions has been intensively studied in mammals. Recently, immediate effects of intense locomotion on the decision-making under uncertainty were reported in the Great Pond snail, Lymnaea stagnalis (Korshunova et al., 2016). In this animal, serotonergic neurons control locomotion, and serotonin modulates many processes underlying behavior, including cognitive ones (memory and learning). Whether serotonin mediates the behavioral effects of intense locomotion in mollusks, as it does in vertebrates, remains unknown. Here, the delayed facilitating effects of intense locomotion on the decision-making in the novel environment are described in Lymnaea. Past exercise was found to alter the metabolism of serotonin, namely the content of serotonin precursor and its catabolites in the cerebral and pedal ganglia, as measured by high-performance liquid chromatography. The immediate and delayed effects of exercise on serotonin metabolism were different. Moreover, serotonin metabolism was regulated differently in different ganglia. Pharmacological manipulations of the serotonin content and receptor availability suggests that serotonin is likely to be responsible for the locomotor acceleration in the test of decision-making under uncertainty performed after exercise. However, the exercise-induced facilitation of decision-making (manifested in a reduced number of turns during the orienting behavior) cannot be attributed to the effects of serotonin.

Abstract
Information on the dynamics of molecules following olfactory dysfunction remains essential for understanding the molecular events involved in the pathological process of olfactory dysfunction. This study for the first time demonstrates a method based on the combination of in vivo microdialysis with high performance liquid chromatography (HPLC) and electrochemical detection (ECD) for the measurement of the dynamics of norepinephrine (NE) in the olfactory bulbs of Sprague-Dawley rats following olfactory dysfunction induced by brain ischemia and its responses toward dexamethasone treatment. The method possesses a high spatial resolution and benefits from in vivo microdialysis and high selectivity and is thus capable of measuring NE in the olfactory bulb of rats. With this method, the basal level of NE in the olfactory bulb was evaluated to be ca. 235 ± 25 nM (n = 6). This level was found to increase by 260 ± 90% at a time point of 240 min after brain ischemia with bilateral ligation of both common carotid arteries. The increase was found to be suppressed upon the treatment of the animals with 0.2% dexamethasone in the olfactory bulb. These results suggest that NE is involved in the pathological process of ischemia-induced olfactory dysfunction and this information is useful to further understand the molecular events involved in olfactory dysfunction.

Abstract
BACKGROUND AND OBJECTIVES Addictive pathology is associated with nervous, immune, and endocrine shifts. Meanwhile, the nature of intersystemic relationship lying beneath addictive disorders remains unclear. The purpose of the study was to identify neuroimmunoendocrine markers of addictive disorders in male subjects defining the nature of their interaction. METHODS The study enrolled 69 subjects aged 18-43 years: 59 males and 10 females divided into those with addictive disorders (n = 39) and conditionally healthy subjects (n = 30). EEG testing with olfactory stimulation, olfactometric, and pressure algometric examinations was carried out. Multiplex technique was applied to determine mitogen-induced production of cytokines IL-10, IL-1, IL-1RA, IL-2, IFN-gamma, TNF-alpha. ELISA method was applied to measure serum cortisol and testosterone levels. RESULTS Olfactory responses to isopropanol with open eyes in addicted patients manifested as increase in alpha-rhythm and beta1-rhythm, with closed eyes presentation of this odorant was accompanied by increase of theta-rhythm in opioid-addicted patients. Male subjects with addictive disorders showed reduced alpha-rhythm in terms of olfactory stimulation with modified emotional evaluation of the odorant, deficient mitogen-induced production of IFN-gamma, and reduced pain sensitivity. Male subjects with opioid addiction had reduced beta1-rhythm in terms of olfactory stimulation, mitogen-induced production of IFN-gamma, and elevated testosterone level. CONCLUSIONS The findings obtained verify potential involvement of nociception, olfaction, and cytokine production in addiction pathogenesis evidencing their various roles depending on the range of psychoactive substances (PAS) and pathology progression. SCIENTIFIC SIGNIFICANCE The data obtained may provide background for unification of reward circuit and inhibitory control concepts in regulation of addictive behavior. (Am J Addict 2017;26:640-648).

Abstract
Having been investigated for over 40 years, some aspects of the biology of terrestrial gastropod's olfactory system have been challenging and highly contentious, while others still remain unresolved. For example, a number of terrestrial gastropod species can track the odor of food, while others have no strong preferences toward food odor; rather they find it by random encounter. Here, while assessing the most recent findings and comparing them with earlier studies, the aspects of the food selection based on olfactory cues are examined critically to highlight the speculations and controversies that have arisen. We analyzed and compared the potential role of airborne odors in the feeding behavior of several terrestrial gastropod species. The available results indicate that in the foraging of most of the terrestrial gastropod species odor cues contribute substantially to food finding and selection. The results also suggest, however, that what they will actually consume largely depends on where they live and the species of gastropod that they are. Due to the voluminous literature relevant to this object, this review is not intended to be exhaustive. Instead, I selected what I consider to be the most important or critical in studies regarding the role of the olfaction in feeding of terrestrial gastropods.
