Emerging evidence transcends the traditional central nervous system (CNS)-centric perspective, revealing that neutrophils, red blood cells (RBCs), and platelets may play critical roles in AD pathogenesis by modulating systemic inflammatory responses, disrupting blood-brain barrier integrity, and participating in the CNS-peripheral interactions.
