13 Dec Discovering the Differences Between Parechovirus Genotypes A1 and A3

Human parechovirus (PeV-A) is known to cause diseases in humans. This group of viruses is very common, and there are several different types. Such as PeV-A1, often associated with mild gastrointestinal diseases in young children. On the other hand, PeV-A3 causes severe diseases with neurological symptoms in neonates. Since PeV-A is detectable in stool and nasopharyngeal samples, it is speculated that PeV-A enters the human body through the respiratory and gastro-intestinal routes.

In a recent publication titled Parechovirus A Infection of the Intestinal Epithelium: Differences Between Genotypes A1 and A3, our PhD student Inés García-Rodriguez categorized PeV-A1 and PeV-A3 replication and tropism in the intestinal epithelium using a 2D model based on human fetal enteroids. Through her research, Ines was able to detect a difference in cell tropism, which may explain the difference in replication kinetics and associated disease in humans.
