Parasitology Today, 1988
Understanding immune evasion by parasites in their insect vectors requires some understanding of the insect immune system. Until fairly recently, technical difficulties in handling cells and plasma hampered laboratory investigations into insect immunology, but modern techniques combined with a sound knowledge of insect physiology are now permitting ...

Current Opinion in Immunology, 1995
Insects are particularly resistant to microorganisms. Their host-defense system relies on several innate reactions: upon injury, the immediate onset of two proteolytic cascades leading to localized blood clotting and to melanization, the latter process involving production of cytotoxic molecules (namely reactive oxygen intermediates); the phagocytosis ...

Innate immunity in higher insects
Current Opinion in Immunology, 1996The hallmark of the innate immune response of higher insects is the rapid and transient synthesis of a battery of broad spectrum antimicrobial peptides by the fat body. The control of the genes encoding these peptides involves cis-regulatory promoter elements homologous to sequences functional in mammalian acute-phase genes.

Insect hemocytes and their role in immunity
Insect Biochemistry and Molecular Biology, 2002The innate immune system of insects is divided into humoral and cellular defense responses. Humoral defenses include antimicrobial peptides, the cascades that regulate coagulation and melanization of hemolymph, and the production of reactive intermediates of oxygen and nitrogen.

We are using the diptericin gene as a model system to study the control of expression of the genes encoding antibacterial peptides during the Drosophila immune reaction. In order to investigate the putative regulatory regions in the diptericin promoter, we performed DNaseI footprinting experiments combined with gel-shift assays in two inducible systems:

BIOLOGICAL MEDIATORS OF INSECT IMMUNITY
Annual Review of Entomology, 1997▪ Abstract Infection in insects stimulates a complex defensive response. Recognition of pathogens may be accomplished by plasma or hemocyte proteins that bind specifically to bacterial or fungal polysaccharides. Several morphologically distinct hemocyte cell types cooperate in the immune response.

Insect immune resistance to parasitoids
Insect Science, 2008AbstractInsect host—parasitoid interactions involve complex physiological, biochemical and genetic interactions. Against endoparasitoids, immune‐competent hosts initiate a blood cell‐mediated response that quickly destroys the intruders and envelops them in a multilayered melanotic capsule. During the past decade, considerable progress has been made in

Eicosanoid-mediated immunity in insects
Developmental & Comparative Immunology, 2018Eicosanoid is a collective term for oxygenated metabolites of C20 polyunsaturated fatty acids. As seen in mammals, eicosanoids play crucial roles in mediating various physiological processes, including immune responses, in insects. Upon microbial pathogen infection, non-self recognition signals are propagated to nearly immune effectors such as ...
