Attachment and #replication of clade 2.3.4.4b #influenza #H5N1 viruses in #human respiratory #epithelium: an in-vitro study, https://etidiohnew.blogspot.com/2025/12/attachment-and-replication-of-clade.html

The experiments were dramatic, here are the
spectacular simulations by Marino's team.

Variable #DPP4 #expression in multiciliated cells of the #human #nasal #epithelium as a determinant for #MERS-CoV tropism, https://etidiohnew.blogspot.com/2025/03/variable-dpp4-expression-in.html

A 2022 avian #H5N1 #influenza A virus from clade 2.3.4.4b attaches to and replicates better in #human respiratory #epithelium than a 2005 H5N1 virus from clade 2.3.2.1

Source: BioRxIV, AbstractBackground: Highly pathogenic avian influenza (HPAI) H5 viruses of the A/Goose/Guangdong/1/1996 (GsGd) lineage pose significant global risks to wildlife, domestic animals, and humans. Recent cross-species transmission events to mammals, including humans, highlight this risk.…

And we also had a variant of your pathway C of #epithelial fold formation : folding by *tensile* mechanical #buckling

(Note: these are my hands on the photo, so technically this is my own's only and single published experiment!)

"Overall, our data suggest that the orientation of spindles in the epithelium plane requires a threshold level of mechanical tension at intercellular junctions."

Rinse aids in #commercial #dishwashers often contain #alcohol #ethoxylate. This substance damages the #intestinal #epithelium, which can lead to chronic #diseases.

@[email protected] Hi, few comments: I think this is a terrible picture choice to represent #Alzheimer's, furthering unhelpful stereotypes, and 2) you don't link to the #study here https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8854390/ which was 3) in *mice* not humans, using chemical damage to #nasal #epithelium and 4) doesn't say anything about nosepicking, and 5) the study didn't find any increase in #AD #pathology: "we could not detect C. pneumoniae inclusions in the brain [...] did not detect any evidence of distinct Aβ deposits"
