Paone P, Cani PD. Mucus barrier, mucins and gut microbiota: the expected slimy partners? Gut 2020;69:2232-43.

There is a misspelling of the Cftr gene in this article. The article has Ctfr instead of Cftr in the following sentence, which should read as:

For example, during high-fat diet feeding, there is an impairment in mucus production and secretion, an enrichment in barrier-disrupting species, and a decrease in the expression of the Cftr gene in mouse ileal enterocytes, causing a reduction in viscosity and density of the mucus and an increase in intestinal permeability.
