Why do some invertebrates store so much carotenoids in their tissues? Storage of carotenoids may not simply be passive and dependent on their environmental availability, as storage variation exists at various taxonomic scales, including among individuals within species. While the strong antioxidant and sometimes immune-stimulating properties of...

Pinaud et al. recently provided the first global investigation of the molecular processes underlying innate immune memory in an invertebrate species. They showed that the memory response of the snail Biomphalaria glabrata to Schistosoma mansoni infection is associated with a shift from cellular to humoral mechanisms.

International audience

In a number of species, individuals exposed to pathogens can mount an immune response and transmit this immunological experience to their offspring, thereby protecting them against persistent threats. Such vertical transfer of immunity, named trans-generational immune priming (TGIP), has been described in both vertebrates and invertebrates....
