THE EXPRESSION OF IMMUNE-RELATED GENES IS INVOLVED IN ASCIDIAN DEVELOPMENT

A first search for coincident gravitational waves and high energy neutrinos using LIGO, Virgo and ANTARES data from 2007

A search for high-energy neutrinos coming from the direction of the Sun has been performed using the data recorded by the ANTARES neutrino telescope during 2007 and 2008. The neutrino selection criteria have been chosen to maximize the selection of possible signals produced by the self-annihilation of weakly interacting massive particles accumulated in the centre of the Sun with respect to the atmospheric background. After data unblinding, the number of neutrinos observed towards the Sun was found to be compatible with background expectations. The 90% CL upper limits in terms of spin-dependent and spin-independent WIMP-proton cross-sections are derived and compared to predictions of two sup…

Immunomodulation and physiological responses of Mytilus galloprovincialis as bioindicators of environmental change

Immunomodulation and physiological responses of Mytilus galloprovincialis as bioindicators of environmental change Oxygenation level temperature increases and changes in food availability are predicted to occur in the future. In such scenario, a global climate change (GCC), there is growing concern for the health status of wild and farmed organisms. Bivalve molluscs, are important components of coastal marine ecosystems, and as sedentary and filter feeders, are good bioindicators of environmental conditions. The ability of organisms to maintain the immunosurveillance unaltered under adverse environmental conditions may enhance theirs survival capability. Only a few studies have investigated…

Evidence of cytotoxic activity against mammalian red blood cell of Na+ channel neurotoxin (Ae1) from sea anemone (Actinia equina)

The diversification of anthozoan toxins played an important role in the ability to colonize various ecological niches. In this study we evaluated the hemolytic activity of HPLC separated fraction of tentacle extracts of sea anemone Actinia equina. Toxic components from acid tissue tentacle extracts were investigated by size exclusion and reverse phase HPLC to characterize cytolytic molecules. A novel low molecular weight active fraction was sequenced by MALDI TOF analysis and a protein correspondent to 5.4 kDa Sodium channel neurotoxin (Ae1) from A. equina was identified. Synthetic Ae1 was assayed and it showed an hemolytic activity against mammalian erythrocytes in a dose dependent manner.…

Variation of environmental condition and diet act on immune parameters of Mytilus galloprovinciali

Variation of environmental condition and diet act on immune parameters of Mytilus galloprovincialis The knowledge of the immunity mechanisms as environmental indicators and their alterations in the case of physical stress can be of fundamental importance in the environmental management programs. Recently has been shown that environmental factors affect immune responses in some species of bivalves. In this study we assessed different enzymatic activities from digestive gland of M. galloprovincialis such esterase, phosphatase and phenoloxidase (PO), involved in digestive inflammatory, detoxification and melanization processes. Particularly, esterases catalyze the hydrolysis reaction of the es…
