Eritrocitos - Quilo de Ciencia podcst - Cienciaes.com

Aunque solemos imaginar las células del cuerpo como estáticas, muchas, como los glóbulos rojos o eritrocitos y las células inmunitarias, están en constante movimiento. Los glóbulos rojos circulan sin descanso para llevar oxígeno, mientras que los neutrófilos “huelen” señales químicas llamadas quimiocinas para localizar infecciones. Una de estas quimiocinas, CXCL12, conocida por guiar células inmunes, también desempeña un papel clave y sorprendente en la maduración de los eritrocitos. Investigadores han descubierto que esta molécula es esencial para que estas células pierdan su núcleo en su fase final. Este hallazgo revela nuevas funciones de CXCL12 y abre caminos para abordar enfermedades sanguíneas.
