El mundo ha reaccionado con euforia a la noticia de que una vacuna contra la COVID-19 está a las puertas ¿Será tan eficaz como afirman? ¿Nos protegerá por mucho tiempo? Todo esto dependerá de la cantidad y calidad de los linfocitos memoria que la vacuna logre generar. Cuando un linfocito B detecta una molécula desconocida, por ejemplo un antígeno presente en un virus, puede responder de dos maneras. Bien el linfocito activado se convierte en un linfocito B memoria, útil para afrontar futuras infecciones, o bien se convierte en una célula productora de anticuerpos que bloquearán al virus para evitar su infección. Una nueva investigación revela el mecanismo que gobierna esa elección. El descubrimiento tendrá importantes implicaciones para el diseño de vacunas. Más información en https://cienciaes.com
