Mitä tapahtuu musiineissa koronavirusinfektiossa? Vastaamaton kysymys

uutisten mukaan musiiniipitoiset eritteet kovasti lisääntyvät  infektion alettua jossain vaiheessa, jopa joku kirjoittaa että nenäkin ja hengitystiet  tulee niin vaikutetuiksi   että ihminen kokee hukkuvansa. en vielä ole löytänyt CoV vaikutusta musiinikirjoon.

Mucins as a New Frontier in Pulmonary Fibrosis.
Abstract
Idiopathic pulmonary fibrosis (IPF) is the most common idiopathic interstitial pulmonary disease with a median survival of 3-5 years after diagnosis. Recent evidence identifies mucins as key effectors in cell growth and tissue remodeling processes compatible with the processes observed in IPF. Mucins are classified in two groups depending on whether they are secreted (secreted mucins) or tethered to cell membranes (transmembrane mucins). Secreted mucins (MUC2, MUC5AC, MUC5B, MUC6-8 and MUC19) are released to the extracellular medium and recent evidence has shown that a promoter polymorphism in the secreted mucin MUC5B is associated with IPF risk. Otherwise, transmembrane mucins (MUC1, MUC3, MUC4, MUC12-17 and MUC20) have a receptor-like structure, sensing the external environment and activating intracellular signal transduction pathways essential for mucosal maintenance and damage repair. In this context, the extracellular domain can be released to the external environment by metalloproteinase action, increased in IPF, thus activating fibrotic processes. For example, several studies have reported increased serum extracellular secreted KL6/MUC1 during IPF acute exacerbation. Moreover, MUC1 and MUC4 overexpression in the main IPF cells has been observed. In this review we summarize the current knowledge of mucins as promising druggable targets for IPF.
