MicroRNA-989 targets 5-hydroxytryptamine receptor1 to regulate ovarian development and eggs production in Culex pipiens pallens

open access: yesParasites & Vectors, 2023
Background Female mosquitoes need a blood meal after mating for their eggs to develop, and this behavior leads to the spread of pathogens. Therefore, understanding the molecular regulation of reproduction in female mosquitoes is essential to control ...

Pathogen intelligence [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Different species inhabit different sensory worlds and thus have evolved diverse means of processing information, learning and memory. In the escalated arms race with host defense, each pathogenic bacterium not only has evolved its individual cellular sensing and behavior, but also collective sensing, interbacterial communication, distributed ...

Transcription factor FTZ-F1 regulates mosquito cuticular protein CPLCG5 conferring resistance to pyrethroids in Culex pipiens pallens

open access: yesParasites & Vectors, 2020
Background Culex pipiens pallens poses a serious threat to human health because of its widespread distribution, high carrier capacity for several arboviruses, frequent human-biting, and growth in urban environments.

Rotavirus Pathogenicity

open access: yesVirology, 1996
The pathogenicity of rotaviruses depends on multiple viral and host factors. In this review the evidence for the involvement of a number of viral genes in the ability to cause disease is presented. Different genes are of importance in different rotavirus-host systems: there is no single pathogenicity factor.

Toxic Effects of Perilla frutescens (L.) Britt. Essential Oil and Its Main Component on Culex pipiens pallens (Diptera: Culicidae)

open access: yesPlants, 2023
Sustainable control of mosquitoes, vectors of many pathogens and parasites, is a critical challenge. Chemical insecticides are gradually losing their effectiveness because of development of resistance, and plant metabolites are increasingly being ...

The Insect Pathogens

open access: yesMicrobiology Spectrum, 2017
ABSTRACTFungi are the most common disease-causing agents of insects; aside from playing a crucial role in natural ecosystems, insect-killing fungi are being used as alternatives to chemical insecticides and as resources for biotechnology and pharmaceuticals.

Identification of the BolA Protein Reveals a Novel Virulence Factor in K. pneumoniae That Contributes to Survival in Host

open access: yesMicrobiology Spectrum, 2022
BolA has been characterized as an important transcriptional regulator, which is induced in the stationary phase of growth and is often associated with bacterial virulence.

SjTat-TPI facilitates adaptive T-cell responses and reduces hepatic pathology during Schistosoma japonicum infection in BALB/c mice

open access: yesParasites & Vectors, 2015
Background Schistosomiasis is a kind of parasitic zoonoses which causes serious damage to public health and social development. China is one of the countries most affected by Schistosoma japonicum and an effective vaccine is still needed.

Stunted microbiota and opportunistic pathogen colonisation in caesarean section birth

open access: yesNature, 2019
Immediately after birth, newborn babies experience rapid colonization by microorganisms from their mothers and the surrounding environment1. Diseases in childhood and later in life are potentially mediated by the perturbation of the colonization of the ...

Plants send small RNAs in extracellular vesicles to fungal pathogen to silence virulence genes

open access: yesScience, 2018
Defense cargo shuttles in vesicles Plants can use small RNAs (sRNAs) to interfere with virulence factor gene expression in pathogens. Cai et al. show that the small mustard plant Arabidopsis shuttles defensive sRNAs into the necrotrophic fungus Botrytis ...
