Helicobacter pylori Infection Remodels Neutrophil‐Derived Extracellular Vesicles, Promoting Stress and Apoptosis in Infected Epithelial Cells

Journal of Extracellular Vesicles, Volume 15, Issue 11, November 2026.
We report that Helicobacter pylori reprograms neutrophils to release extracellular vesicles (HPN‐EVs) with distinct biophysical and molecular features. These neutrophil‐derived vesicles, enriched in neutrophil granule proteins, LL‐37 and pro‐apoptotic miRNAs, suppress epithelial PI3K/Akt signalling, increase ROS, and induce mitochondrial dysfunction ...

A One Health Molecular Investigation and Exploratory Epidemiological Analysis of Cryptosporidium spp. in A Shared Human‐Animal Ecosystem

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A One Health molecular investigation of Cryptosporidium across humans, animals and the environment revealed the circulation of multiple zoonotic species and subtypes within a shared ecosystem. Molecular characterisation and phylogenetic analysis highlighted transmission at the human–animal–environment interface. The findings emphasise the importance of

Serum IgG Responses to gp15 and gp40 Protein-Derived Synthetic Peptides From Cryptosporidium parvum

Frontiers in Cellular and Infection Microbiology, 2022
Cryptosporidium spp. are responsible for moderate to severe diarrhea, mainly in children and immunocompromised patients. Using ELISA, the recognition of synthetic peptides generated from the sequences of the Cryptosporidium parvum gp40 and gp15 proteins ...
