Procesos de activación y maduración de células B en el centro germinal

Procesos de activación y maduración de los linfocitos B que tienen lugar en el centro germinal:
Al activarse, el linfocito B se mueve desde la zona del manto y entra al centro germinal. Tiene lugar la proliferación de linfocitos B (expansión clonal) y la afinidad del anticuerpo por el antígeno aumenta a través del proceso de hipermutación somática. Los ciclos repetidos de proliferación e hipermutación afinan el receptor de linfocito B. Sin embargo, no todos los linfocitos B continúan diferenciándose, especialmente si la afinidad es débil. La apoptosis ocurre si la unión antígeno-anticuerpo no está optimizada. Los linfocitos B con fuerte afinidad sobreviven (selección), con la ayuda de las señales de supervivencia de las células dendríticas foliculares y los linfocitos T. Estos linfocitos B seleccionados pasan al cambio de clase y la diferenciación en células plasmáticas o células de memoria.
