Amyloid-related imaging abnormalities after immunotherapy: How might brain microvascular basement membrane components be involved?
Vinters HV, Magaki S.. Journal of Alzheimer's disease : JAD, 2026-07-11
Topic: Brain proteins, microglia and lab models
Basement membrane components are integral to the physiologic function of cerebral microvessels. Immunotherapy (including by the use of lecanemab) in Alzheimer's disease patients may result in vascular complications identified by neuroimaging (ARIA-E and ARIA-H). This pilot study (on a relatively small number of human brain specimens) suggests one mechanism might be through the effects of lecanemab on a collagen component of said microvessel walls. It utilizes microvessels isolated from human brains (of Alzheimer's disease patients) and maintained in a viable state, to examine this mechanism using novel biochemical and molecular approaches. These yield preliminary evidence of how lecanemab may influence a specific component of the cerebral microvasculature and suggest other studies that may be used to address this important question.

How this study scored 47/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 27 of the 58 points we could judge it on, which is 47 out of 100.
