Dimethyl fumarate decreases short-term but not long-term inflammation in a focal EAE model of neuroinflammation

EJNMMI Research, 2022
Highlights In a focal rat DTH-EAE model of neuroinflammation, dimethyl fumarate decreases the uptake of TSPO PET tracer [18F]GE-180 in the short term. Long-term [18F]GE-180 follow-up did not indicate a treatment effect.

[18F]Fluoride uptake in various bone types and soft tissues in rat

EJNMMI Research, 2023
Background In the development of new 18F-labelled tracers, it is important to assess the amount of released [18F]fluoride taken up in the bones of experimental animals because all 18F-labelled PET-tracers are prone, to lesser or higher degree, to undergo

ImmunoPET imaging of amyloid-beta in a rat model of Alzheimer’s disease with a bispecific, brain-penetrating fusion protein

Translational Neurodegeneration, 2022
Background Hijacking the transferrin receptor (TfR) is an effective strategy to transport amyloid-beta (Aβ) immuno-positron emission tomography (immunoPET) ligands across the blood–brain barrier (BBB).
