Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

open access: yesThe FEBS Journal, Volume 293, Issue 6, Page 1681-1707, March 2026.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Associations between early life exposure to parvovirus and antibiotic treatment and the occurrence and severity of later chronic enteropathy in dogs

open access: yesVeterinary Record, Volume 198, Issue 4, Page e142-e149, 14/21 February 2026.
Abstract Background Canine parvovirus (CPV) infection is reportedly associated with chronic enteropathy (CE), but infected puppies are often treated with antibiotics, which may also promote CE. This study aims to compare the presence and severity of CE among dogs that were CPV‐infected, treated with antibiotics or healthy during puppyhood.
