Higher temperature accelerates the aging-dependent weakening of the melanization immune response in mosquitoes

open access: yesPLoS Pathogens
The body temperature of mosquitoes, like most insects, is dictated by the environmental temperature. Climate change is increasing the body temperature of insects and thereby altering physiological processes such as immune proficiency.

Extracellular vesicles secreted by Brugia malayi microfilariae modulate the melanization pathway in the mosquito host

open access: yes, 2022
Vector-borne, filarial nematode diseases represent a significant and affecting disease burden in humans, domestic animals, and livestock worldwide. Parasitic filarial nematodes require both an intermediate (vector) host and a definitive (mammalian) host ...

Cellular immunity and pathogen strategies in combative interactions involving Drosophila hosts and their endoparasitic wasps [PDF]

open access: yesInvertebrate Survival Journal, 2010
Various cellular innate immune responses protect invertebrates from attack by eukaryotic pathogens. In insects, assessments of the factor(s) causing, or contributing to, pathogen mortality have long considered as toxic components certain molecules ...

Immune Regulation of Plasmodium Is Anopheles Species Specific and Infection Intensity Dependent

open access: yesmBio, 2017
Malaria parasite ookinetes must traverse the vector mosquito midgut epithelium to transform into sporozoite-producing oocysts. The Anopheles innate immune system is a key regulator of this process, thereby determining vector competence and disease ...

Characterization of the MYB Genes Reveals Insights Into Their Evolutionary Conservation, Structural Diversity, and Functional Roles in Magnaporthe oryzae

open access: yesFrontiers in Microbiology, 2021
The myeloblastosis (MYB) transcription factor family is evolutionarily conserved among plants, animals, and fungi, and contributes to their growth and development.

Secondary Sexual Trait Melanization in “Black” Scavenger Flies: Nutritional Plasticity and Its Evolution [PDF]

open access: yes, 2022
The black scavenger fly Sepsis thoracica exhibits polyphenic development resulting in alternate small black and large amber male morphs. Although the behavior, ecology, and physiology of both morphs are being scrutinized, the evolutionary origins of the ...

Recent Advances in the Use of Galleria mellonella Model to Study Immune Responses against Human Pathogens

open access: yesJournal of Fungi, 2018
The use of invertebrates for in vivo studies in microbiology is well established in the scientific community. Larvae of Galleria mellonella are a widely used model for studying pathogenesis, the efficacy of new antimicrobial compounds, and immune ...

Influence of Hyperproteinemia on Insect Innate Immune Function of the Circulatory System in Bombyx mori

open access: yesBiology, 2021
Metabolic disorders of the circulatory system of animals (e.g., hyperglycemia and hyperlipidemia) can significantly affect immune function; however, since there is currently no reliable animal model for hyperproteinemia, its effects on immunity remain ...

Encapsulation and Hemocyte Numbers in Crocidolomia pavonana and Spodoptera litura Fabricius (Lepidoptera) Attacked by Parasitoid Eriborus argenteopilosus Cameron (Hymenoptera)

open access: yesHayati Journal of Biosciences, 2009
Eriborus argenteopilosus is the most important parasitoid attacking cabbage pest Crocidolomia pavonana in Indonesia. Previous studies proved that parasitoid encapsulation was found to be an important factor limiting the effectiveness of the parasitoid in

A Chirality‐Converted Bacteriolytic Dodecapeptide Regulates Vibrio‐Induced Polymicrobial Infection and Ameliorates Invasion‐Associated Gut Microbiota Disequilibrium

open access: yesAdvanced Science, EarlyView.
Multidrug‐resistant Vibrio infections are rising rapidly and threaten coastal populations worldwide. This study introduces D‐zp37, a chirality‐engineered antimicrobial peptide with exceptional potency against resistant Vibrio species. D‐zp37 kills planktonic cells, blocks mixed‐species biofilms, disrupts essential bacterial stress responses, and shows ...
