Immunohistochemical study reveals increased osteopontin and alphaB-crystallin in multiple sclerosis white matter, highlighting their pathogenic roles beyond active lesions.

Key Points

To assess the expression patterns, cellular distribution, and correlation of osteopontin and alphaB-crystallin across various multiple sclerosis lesion categories and normal-appearing white matter.
Constructed tissue microarrays from paraffin-embedded brain donor blocks comprising chronic active plaques, chronic inactive plaques, and normal-appearing white matter from 7 multiple sclerosis cases, alongside white matter from 5 controls.
Evaluated the cellular distribution and protein expression of osteopontin and alphaB-crystallin in relation to myelin density and microglial activation.
Both osteopontin and alphaB-crystallin demonstrated elevated expression across all multiple sclerosis tissue categories compared to control white matter.
Osteopontin expression increased progressively with plaque activity, whereas alphaB-crystallin elevation occurred independently of demyelination.
Normal-appearing white matter showed a significant correlation between high levels of osteopontin and alphaB-crystallin, with osteopontin localizing primarily to astrocytes and alphaB-crystallin appearing on astrocytes, oligodendrocytes, and demyelinated axons.
