How does adulteration of wax foundation affect phenoloxidase and lysozyme activities as selected parameters of immunity in Apis mellifera?

open access: yesJournal of Veterinary Research
The adulteration of wax foundation is, for many reasons, a growing problem of modern beekeeping not only in Europe but also around the world. Wax foundation contaminated with stearin addition leads to a brood die-off, while paraffin addition negatively ...

Acute Dietary Restriction Acts via TOR, PP2A, and Myc Signaling to Boost Innate Immunity in Drosophila

open access: yesCell Reports, 2017
Dietary restriction promotes health and longevity across taxa through mechanisms that are largely unknown. Here, we show that acute yeast restriction significantly improves the ability of adult female Drosophila melanogaster to resist pathogenic ...

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

open access: yesInsect Molecular Biology, Volume 35, Issue 5, Page 556-575, October 2026.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola

open access: yesInsect Molecular Biology, Volume 35, Issue 5, Page 576-593, October 2026.
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

open access: yesNew Phytologist, Volume 252, Issue 1, Page 324-339, October 2026.
Experimental design. Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in grazed systems.

Effect of Inhibitors on Phenoloxidase of Mycobacterium leprae [PDF]

open access: yesJournal of Bacteriology, 1969
Previous results had shown that the human leprosy bacilli possess a phenoloxidase, which, when compared with the enzyme from mammalian and plant sources, seemed unique in the range of substrates utilized and in the nature of the products formed.

Bacterial Infection Increases Reproductive Investment in Burying Beetles

open access: yesInsects, 2015
The Nicrophorus genus lives and breeds in a microbe rich environment. As such, it would be expected that strategies should be in place to counter potentially negative effects of the microbes common to this environment. In this study, we show the response

Purification and characterization of hemocyte phenoloxidases in Chilo suppressalis walker (Lepidoptera: Crambidae) [PDF]

open access: yesArchives of Biological Sciences, 2015
In the current study, two phenoloxidases (POs) from the larvae of Chilo suppressalis Walker were extracted and purified by column chromatography using Sepharyl G-100 and DEAE-Cellulose fast flow column.
