Domaine(s)
  • Immunologie
CONT

Les anticorps cytotoxiques (IgM ou plus rarement IgG) entraînent la destruction de la cellule sur laquelle ils se sont fixés par activation locale du complément. Ce mécanisme [...] semble en fait assez peu intervenir en immunopathologie. Les anticorps cytotoxiques paraissent néanmoins jouer un rôle important dans les crises hémolytiques des anémies hémolytiques auto-immunes et dans le rejet hyperaigu des greffes d'organe.
