SARS-CoV-2 Symptoms during the Omicron Surge Differ between Boosted and Vaccinated Non-Boosted Persons.

To determine the impact of booster COVID-19 vaccination on SARS-CoV-2 symptoms. : The Omicron surge of infections provided an opportunity to evaluate symptoms in relation to booster receipt. At a US medical college, the number, type, and duration of symptoms were evaluated for 476 students or employees, factoring in days between last vaccination and SARS-CoV-2 diagnosis.

A cryptic fragment from fibronectin's III1 module localizes to lipid rafts and stimulates cell growth and contractility.

The interaction of cells with the extracellular matrix (ECM) form of fibronectin (FN) triggers changes in growth, migration, and cytoskeletal organization that differ from those generated by soluble FN. As cells deposit and remodel their FN matrix, the exposure of new epitopes may serve to initiate responses unique to matrix FN. To determine whether a matricryptic site within the III1 module of FN modulates cell growth or cytoskeletal organization, a recombinant FN with properties of matrix FN was constructed by directly linking the cryptic, heparin-binding COOH-terminal fragment of III1 (III1H) to the integrin-binding III8-10 modules (glutathione-S-transferase [GST]-III1H,8-10).
