Insect immunity: the post-genomic era [PDF]
SummaryInsects have a complex and effective immune system, many components of which are conserved in mammals. But only in the last decade have the molecular mechanisms that regulate the insect immune response—and their relevance to general biology and ...

Social immunity in insects [PDF]
Current Biology, 2019 When animals become sick, infected cells and an armada of activated immune cells attempt to eliminate the pathogen from the body. Once infectious particles have breached the body's physical barriers of the skin or gut lining, an initially local response quickly escalates into a systemic response, attracting mobile immune cells to the site of infection.

Journal of Innate Immunity, 2023 Insect humoral immune responses are regulated in part by protease cascades, whose components circulate as zymogens in the hemolymph. In mosquitoes, these cascades consist of clip-domain serine proteases (cSPs) and/or their non-catalytic homologs, which ...

Endocrine regulation of immunity in insects [PDF]
The FEBS Journal, 2020 Organisms have constant contact with potentially harmful agents that can compromise their fitness. However, most of the times these agents fail to cause serious disease by virtue of the rapid and efficient immune responses elicited in the host that can range from behavioural adaptations to immune system triggering. The immune system of insects does not

Plasticity in immune responses in a model insect [PDF]
, 2011 PhDIn order to understand how the environment, parental environment and inbreeding influence immune function and life history traits, I carried out a series of experiments using the Indian meal moth, Plodia interpunctella, as a model organism.

Nitric Oxide-Induced Calcineurin A Mediates Antimicrobial Peptide Production Through the IMD Pathway
Frontiers in Immunology, 2022 Nitric oxide (NO) at a high concentration is an effector to kill pathogens during insect immune responses, it also functions as a second messenger at a low concentration to regulate antimicrobial peptide (AMP) production in insects.

Nature Communications, 2017 Immunity deteriorates with age in animals but less is known about how aging affects immunity in plants. Here, Maoet al. show that responsiveness to the major insect defense hormone JA declines as plants age, but insect resistance still increases as ...

Eicosanoid Actions in Insect Immunity [PDF]
Journal of Innate Immunity, 2009 Insects express 3 lines of protection from infections and invasions. Their cuticles and peritrophic membranes are physical barriers. Infections and invasions are quickly recognized within insect bodies, and recognition launches 2 lines of innate immune reactions.

Nuclear processes associated with plant immunity and pathogen susceptibility [PDF]
, 2015 Plants are sessile organisms that have evolved exquisite and sophisticated mechanisms to adapt to their biotic and abiotic environment. Plants deploy receptors and vast signalling networks to detect, transmit and respond to a given biotic threat by ...
