Participación de la vitamina A en la producción de IgA secretora en el epitelio del tracto respiratorio para la potencial protección de infección por SARS-CoV-2

Abstract: El SARS-CoV-2 continúa infectando a miles de personas a nivel mundial. Se ha establecido que el principal mecanismo de transmisión del SARS-CoV-2 es por vía aérea, por lo que infecta inicialmente el tracto respiratorio. Actualmente, la eficacia de los fármacos utilizados contra COVID-19 es limitada y a pesar de que los programas de inmunización han iniciado, existe una desigualdad internacional en la distribución de vacunas. En este sentido, la búsqueda de terapias coadyuvantes continúa siendo una alternativa … Show more

“…In addition, it has been suggested that SIgA in BALF of mice inoculated with live attenuated vaccine d16 developed with SARS-CoV-2 lacking nsp16 can effectively activate mucosal immunity against SARS-CoV-2 [ 116 ]. As a potential protective factor, Vitamin A have an effect on SARS-CoV-2 infection because of the fact that retinoic acid, the active metabolite of vitamin A, can mediate the production of SIgA in the respiratory tract, thus exerting the immune regulation function [ 117 ]. In addition, The supplement of neutrophil elastase inhibitor can promote the development of mucosal immunity including SIgA [ 118 , 119 ], by stimulation of B cell activating factor, proliferation inducing ligand and IL-10 of TNF family [ 120 ], it can help to produce SIgA to prevent infection of pathogens at one or more mucosal sites, which is of great significance for the development of future vaccines.…”
