Early detection of liposome brain localization in rat experimental allergic encephalomyelitis.

Abstract

Blood-brain barrier (BBB) permeability increases prior to the development of clinical signs in early-stage multiple sclerosis (MS). Detection of subtle changes would thus be helpful for diagnostic purposes and rapid therapeutic decisions before new episodes. Since multiple sclerosis and experimental allergic encephalomyelitis (EAE) have numerous common features, in particular BBB-permeability characteristics, and since we have previously shown that BBB localization is disturbed by tumors, embolism, and mannitol injection, we investigated BBB-liposome permeability in an EAE rat model. Twenty young male Lewis rats received a single intradermal inoculation of guinea-pig spinal cord. The effect of the Freund's adjuvant and spinal cord alone on brain permeability were also assessed. In order to compare solution permeability and liposome localization, radioactive liposomes and, 1 h later, 99mTc-DTPA were injected intravenously. Scintigraphic acquisitions were obtained to follow the biodistribution of radioactivity in the whole body. Each rat was subjected to a first examination before inoculation and then every two days until completion and may be considered as its own control. EAE induced a previously unreported increase in global-body permeability, probably due to inflammation. Liposome brain localization and brain/heart ratio were significantly different between normal animals and those with early-stage EAE (before appearance of clinical signs) and distinguished between different disease stages in clinically patent EAE. The index of disease progression was modified earlier than with 99mTc-DTPA injection. One explanation may be particle pick-up by circulating macrophages, which cross the BBB during this pathology. For clinical applications, experiments must be confirmed on models more reliable for human multiple sclerosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
