Organisational immunity in social insects
Current Opinion in Insect Science, 2014Selection for disease control is believed to have contributed to shape the organisation of insect societies-leading to interaction patterns that mitigate disease transmission risk within colonies, conferring them 'organisational immunity'. Recent studies combining epidemiological models with social network analysis have identified general properties of

Temperature stress and insect immunity
Journal of Thermal Biology, 2017This mini-review summarizes the recent knowledge concerning the role of temperature in the immune response of insects. The heat-shock is described as a common phenomenon in both homotherms and poikilotherms, and the role of heat-shock proteins in innate immunity is recalled taking into account its evolutionary aspects.

Comparative genomics of insect immunity
2009Abstract This chapter compares the Drosophila group with mosquitoes and honeybees to disentangle common themes from specific components of immunity. Honeybees, for example, have a relatively small set of immune genes which demonstrate a high degree of conservatism.

Gut immunity in Lepidopteran insects
Developmental & Comparative Immunology, 2016Lepidopteran insects constitute one of the largest fractions of animals on earth, but are considered pests in their relationship with man. Key to the success of this order of insects is its ability to digest food and absorb nutrition, which takes place in the midgut. Because environmental microorganisms can easily enter Lepidopteran guts during feeding,

Bacteria and antiviral immunity in insects
Current Opinion in Insect Science, 2015Tripartite interactions between viruses, bacteria and hosts can have significant implications for the outcome of infections. In insects recent studies have shown that these interactions can greatly influence the transmission of vector borne disease, including transmission of dengue virus.

Thioester-containing proteins and insect immunity
Molecular Immunology, 2004Here, we discuss the role of thioester-containing proteins in innate immune responses of insects. TEPs are represented by multi-member families both in the fruitfly, Drosophila melanogaster, and in the mosquito, Anopheles gambiae. Phylogenetic analysis of the family suggests that in these two dipteran species evolution of TEPs followed independent ...

The injection of Escherichia coli and Micrococcus luteus into the hemocoel of Aedes aegypti induces a potent antibacterial activity in the hemolymph. We have purified and fully characterized three 40-residue antibacterial peptides from the hemolymph of bacteria-challenged mosquitoes that are absent in naive mosquitoes.

Diptericins are 9 kDa inducible antibacterial peptides initially isolated from immune haemolymph of Phormia (Diptera). Following the isolation of a Drosophila cDNA encoding a diptericin homologue, we have now cloned a genomic fragment containing the Drosophila diptericin gene.

Insect Immunity to Entomopathogenic Fungi
2016The study of infection and immunity in insects has achieved considerable prominence with the appreciation that their host defense mechanisms share many fundamental characteristics with the innate immune system of vertebrates. Studies on the highly tractable model organism Drosophila in particular have led to a detailed understanding of conserved innate
