ABSTRACT
Significance The efficacy of immunotherapy in Alzheimer’s disease is limited, partly because antibodies, administered peripherally, have poor access to the brain. Focused ultrasound (FUS) with microbubbles allows passage antibodies from blood In a mouse model disease, blood, and without FUS, reduced amyloid pathology. contrast, FUS was required deliver sufficient hippocampus effectively promote neurogenesis. Neurogenesis, regenerative process involved memory functions, impaired disease. Putative contributors stimulation neurogenesis include decrease proinflammatory cytokine TNF-α. holds potential increase for
