Cerebrospinal fluid protein elevations in Alzheimer's disease are dissociated from immune cell composition

open access: yesAlzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 3, July/September 2026.
Abstract INTRODUCTION Elevated cerebrospinal fluid (CSF) inflammatory proteins have been reported in Alzheimer's disease (AD), yet whether they reflect peripheral immune cell infiltration or central nervous system (CNS)–intrinsic pathological processes remains unclear. We tested whether AD exhibits a distinct CSF protein signature and how it relates to

PET Imaging of Synaptic Density: Challenges and Opportunities of Synaptic Vesicle Glycoprotein 2A PET in Small Animal Imaging

open access: yesFrontiers in Neuroscience, 2022
The development of novel PET imaging agents for synaptic vesicle glycoprotein 2A (SV2A) allowed for the in vivo detection of synaptic density changes, which are correlated with the progression and severity of a variety of neuropsychiatric diseases. While

Movement Disorders Associated with 22q11.2 Microdeletion: A Scoping Review

open access: yesMovement Disorders Clinical Practice, Volume 13, Issue 6, Page 1399-1417, June 2026.
Abstract Background Movement disorders have recently emerged as important neurologic manifestations of the 22q11.2 microdeletion that affects nearly one in every 2000 live births. Objective We aimed to map the existing evidence regarding the spectrum, diagnosis and treatment, and etiopathogenesis of movement disorders associated with 22q11.2 ...

Preclinical PET Studies of [11C]UCB-J Binding in Minipig Brain [PDF]

open access: yes
Purpose: Loss of neuronal synapse function is associated with a number of brain disorders. The [11C]UCB-J positron emission tomography (PET) tracer allows for in vivo examination of synaptic density, as it binds to synaptic vesicle glycoprotein 2A (SV2A)

Relationship between tau and SV2A in the neurotypical population and translation to the Down syndrome population

open access: yesAlzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background Synaptic density loss has been proposed as a major neuronal mechanism through which cognition degrades in Alzheimer's disease (AD). PET imaging studies have observed synaptic density change across the AD continuum using SV2A radiotracer [11C]UCB‐J.

Synaptic density imaging in behavioral variant frontotemporal dementia: A comparison of 18F‐SynVesT‐1 and 18F‐FDG PET

open access: yesAlzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Synapse loss, a key feature of behavioral variant frontotemporal dementia (bvFTD), can now be visualized in vivo using positron emission tomography (PET) that targets synaptic vesicle glycoprotein 2A (SV2A). Comparing this new imaging method with the clinical standard of glucose metabolism using 18F‐fluorodeocyglucose (18F‐FDG ...

Toward Harmonizing Quantification of Dopamine Neuron Imaging Biomarkers in Parkinson's Disease: The Centamine Scale

open access: yesAnnals of Neurology, Volume 99, Issue 4, Page 949-963, April 2026.
Objective Dopaminergic imaging is a key biomarker for both the investigation of the biology of Parkinson's disease and related synucleinopathies and the evaluation of potential therapies in clinical trials. This work presents a harmonized approach for quantifying dopaminergic molecular imaging tracers, such as [123I]ioflupane (dopamine transporter scan
