Anticuerpos superglue - Quilo de Ciencia podcast - Cienciaes.com

Hace más de un siglo, se descubrió que podíamos defendernos de las infecciones usando anticuerpos, unas proteínas que fabrica nuestro cuerpo. Al principio, se usaban sueros de animales, como caballos, para curar enfermedades. Hoy, la ciencia ha creado anticuerpos súper precisos, como los monoclonales. Un grupo de científicos ha ido más allá y ha diseñado un nuevo tipo de anticuerpo, una “super IgM”, que actúa como una súper araña con patas muy fuertes para unirse a los agentes infecciosos. Al aplicarlo en un spray nasal, protegió a ratones contra la gripe. En el futuro, podría ayudarnos a prevenir muchas infecciones respiratorias sin necesidad de vacunas tradicionales.
