The Mechanisms of Social Immunity Against Fungal Infections in Eusocial Insects

open access: yesToxins, 2019
Entomopathogenic fungus as well as their toxins is a natural threat surrounding social insect colonies. To defend against them, social insects have evolved a series of unique disease defenses at the colony level, which consists of behavioral and ...

Jasmonate response decay and defense metabolite accumulation contributes to age-regulated dynamics of plant insect resistance

open access: yesNature 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 ...

Nitric Oxide-Induced Calcineurin A Mediates Antimicrobial Peptide Production Through the IMD Pathway

open access: yesFrontiers 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.

Eicosanoid Actions in Insect Immunity [PDF]

open access: yesJournal 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.

Endocrine regulation of immunity in insects [PDF]

open access: yesThe 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

Selection on insect immunity in the wild [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2004
The strength of selection on immune function in wild populations has only been examined in a few vertebrate species. We report the results from a study measuring selection on a key insect immune enzyme, phenoloxidase (PO), in a wild population of the damselfly Calopteryx xanthostoma. We followed individually marked males from the pre-reproductive adult

Correction to: De novo profiling of RNA viruses in Anopheles malaria vector mosquitoes from forest ecological zones in Senegal and Cambodia

open access: yesBMC Genomics, 2019
Following the publication of this article [1], the authors reported that the original shading in columns 3 and 4 of Table 3, which indicated the presence or absence of viruses in each library, had been removed during typesetting.

Insect prophenoloxidase: the view beyond immunity

open access: yesFrontiers in Physiology, 2014
Insect prophenoloxidase (PPO) is an important innate immunity protein due to its involvement in cellular and humoral defense. It belongs to a group of type-3 copper-containing proteins that occurs in almost all organisms.

De novo profiling of RNA viruses in Anopheles malaria vector mosquitoes from forest ecological zones in Senegal and Cambodia

open access: yesBMC Genomics, 2019
Background Mosquitoes are colonized by a large but mostly uncharacterized natural virome of RNA viruses, and the composition and distribution of the natural RNA virome may influence the biology and immunity of Anopheles malaria vector populations ...

Leucine-Rich Immune Factor APL1 Is Associated With Specific Modulation of Enteric Microbiome Taxa in the Asian Malaria Mosquito Anopheles stephensi

open access: yesFrontiers in Microbiology, 2020
The commensal gut microbiome is contained by the enteric epithelial barrier, but little is known about the degree of specificity of host immune barrier interactions for particular bacterial taxa. Here, we show that depletion of leucine-rich repeat immune
