PROBING SAFETY OF NANO-OBJECTS BY OUTLINING SEA URCHIN IMMUNE-SIGNALLING CASCADES byA. Pinsino, C. Costa, V. Matranga, R.

A survey for immune genes has shown that the immune system is complex, sophisticated and mediated by an amazingly large repertoire of host sensors genes, part of which are closely related to human homologs. Under in vivo and vitro experimental conditions immune cells have shown to respond to environmental hazards, including metal oxide NPs, by the modulation of a subset of stress and immune response proteins and genes. Here we focused on the molecular basis of the effects ofTitanium dioxide (TiO2) and iron oxide (Fe3O4) nanoparticles on sea urchin immune cell behavior in vitro. NPs influence the signalling cascades involving a complex network of genes encoding for proteins with different functions.
