Role for Complement C5 in Eosinophilic Inflammation of Severe Asthma

open access: yesAllergy, EarlyView.
Complement activation module, particularly C5, is positively associated with eosinophilic inflammation in severe asthma cohorts. Elevated C5 expression correlates with poor lung function improvement and persistent eosinophilic inflammation. Mouse model studies confirm that C5 exacerbates eosinophilic inflammation, highlighting its potential as a ...

Intestinal metaplasia of the stomach. A status report [PDF]

open access: yesCancer, 1994
Intestinal metaplasia in the stomach increases the risk of gastric cancer, and the increased risk is proportional to the extent of the metaplasia. This risk could be generated by one or more mechanisms: (1) the metaplastic tissue is an early step in a multistep induction process; (2) the metaplastic tissue is an epigenetic change that raises the pH of ...

Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

open access: yesAllergy, EarlyView.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.
