“…These effects have been associated with increased susceptibility toward pathogen infection. Similar effects have been described for pesticides with different chemical nature, such as atrazine, hexachlorobenzene, glyphosate in snails , and lindane in sea urchins . However, experiments combining exposure to pesticides and subsequent bacteriological challenge have only been performed in the oyster Crassostrea gigas .…”

“…Humoral enzyme activity may suffer alterations in organisms exposed to pesticides, affecting the immune response capacity. For example, in the sea urchin Paracentrotus lividus , antibacterial activity decreases after 24 h to 48 h of exposure to the organochlorine insecticide lindane . In mice exposed to atrazine, serum lysozyme decreases after 28 d from injection .…”

The aim of the present study was to characterize the immune response-total hemocyte number, cell type proportion, hemocyte viability, lysosomal membrane stability, phagocytic activity, cellular acid and alkaline phosphatase activity, and humoral bacteriolytic and phenoloxidase activity--in Diplodon chilensis exposed to 0.2 mg/L of azinphos-methyl (AZM), using Escherichia coli as immunological and pro-oxidant challenges. In addition, glutathione-S-transferase and lipid peroxidation thiobarbituric acid reactive substances were analyzed in gill tissue. Mussels from an unpolluted site were treated for 3 d as follows: 1) experimental control; 2) solvent effects control (acetone 0.01%); 3) bacterial challenge effects control (E. coli, 5 cells/mL × 10 cells/mL); 4) pesticide effects control (AZM in acetone); 5) control for combined effects of solvent and bacterial challenge; and 6) exposed to AZM, then challenged with E. coli. The results showed increased granulocyte proportion and phagocytic activity. Partial reversion of deleterious effects of E. coli on lysosomal membranes was observed in mussels exposed to AZM and then challenged with E. coli. Total hemocyte number and humoral bacteriolytic activity were increased only by E. coli challenge. Acid phosphatase activity was increased by both E. coli and AZM, whereas the stimulating effect of E. coli on alkaline phosphatase activity was negatively modulated by AZM. Azinphos-methyl inhibited phenoloxidase activity regardless of the E. coli challenge. Gill glutathione-S-transferase activity was increased by E. coli treatment either alone or pretreated with acetone or AZM and by AZM alone. Thiobarbituric acid reactive substance levels were reduced by AZM alone or combined with the E. coli challenge and by acetone followed by the E. coli challenge. Both acetone and AZM seem to be important modulators of immune and antioxidant responses in D. chilensis. Environ Toxicol Chem 2017;36:1785-1794. © 2016 SETAC.

“…Coelomocyte number and cell type proportion, as well as many functional responses, vary with the species and the physiological conditions of individuals, as a response to environmental factors, pollutants, pathogens or accidental injuries (Matranga et al 2000 ; Pinsino et al 2007 ; Ramírez-Gomez et al 2010 ). Exposure of P. lividus to pollutants, such as lindane and zinc, or accidental injuries induced an increase in red spherula cells, considered as primary cells possibly affected by stressful conditions (Matranga et al 2000 ; Pagliara and Stabili 2012 ; Stabili and Pagliara 2015 ).…”

Seawater pH lowering, known as ocean acidification, is considered among the major threats to marine environment. In this study, post-spawning adults of the sea urchin Paracentrotus lividus were maintained at three pH values (8.0, 7.7, 7.4) for 60 days. Physiological, biochemical, cellular, behavioural and reproductive responses were evaluated in males and females. Significant differences between sexes were observed, with higher ammonia excretion and lower catalase activity in males. Respiration rate (after 21 days), catalase activity in gonads and total coelomocyte count showed the same increasing trend in males and females under low pH. Ammonia excretion, gonadosomatic index and lysozyme activity exhibited opposite responses to low pH, with an increasing trend in males and decreasing in females. Results demonstrated that exposure to low pH could result in different response strategies of male and female sea urchins at a physiological, biochemical and immunological level. Reduced female gonadosomatic index under low pH suggested decreased energy investment in reproduction.

“…A small volume of water (10-20 L) was changed weekly, and the animals were fed once a week with commercial invertebrate food (Azoo, Taikong Corp., Taiwan). Sea urchins were acclimatised for at least 4 weeks, a time period deemed sufficient for immunological studies in the Mediterranean sea urchin P.lividus [12][13][14][15].…”

Changes in the proteome of sea urchin Paracentrotus lividus coelomocytes in response to LPS injection into the body cavity

et al. 2020

View full text Add to dashboard Cite

BackgroundThe immune system of echinoderm sea urchins is characterised by a high degree of complexity that is not completely understood. The Mediterranean sea urchin Paracentrotus lividus coelomocytes mediate immune responses through phagocytosis, encapsulation of nonself particles, and production of diffusible factors including antimicrobial molecules. Details of these processes, and molecular pathways driving these mechanisms, are still to be fully elucidated.
