AbstractObjectiveTo evaluate the association between a preidentified voice biomarker and incident coronary artery disease (CAD) events. MethodsPatients referred for clinically indicated coronary angiography underwent a total of three 30-second voice recordings using the Vocalis Health smartphone application between January 1, 2015, and February 28, 2017. A pre-established voice biomarker was derived from each individual recording, …

Mucosal immune response in BNT162b2 COVID-19 vaccine recipients
Although the BNT162b2 COVID-19 vaccine is known to induce IgG neutralizing antibodies in serum protecting against COVID-19, it has not been studied in detail whether it could generate specific immunity at mucosal sites, which represent the primary route of entry of SARS-CoV-2. MethodsSamples of serum and saliva of 60 BNT162b2-vaccinated healthcare workers were collected at …

Intranasal priming induces local lung-resident B cell populations that secrete protective mucosal antiviral IgA
Flu defense via lung-resident IgA+ memory B cellsSecretory IgA antibody is known to be a key effector molecule in establishing effective antiviral immunity in the lungs, but the specific cell types producing this mucosal IgA and their physical locations are unclear. Oh et al. analyzed pulmonary IgA-secreting cells in mice after prior influenza infection or …
Impaired local intrinsic immunity to SARS-CoV-2 infection in severe #COVID-19
SARS-CoV-2 infection can cause severe respiratory COVID-19. However, many individuals present with isolated upper respiratory symptoms, suggesting potential to constrain viral pathology to the nasopharynx. Which cells SARS-CoV-2 primarily targets and how infection influences the respiratory epithelium remains incompletely understood. We performed scRNA-seq on nasopharyngeal swabs from 58 healthy and COVID-19 participants. During COVID-19, we …
