FXTAS presents with upregulation of the cytokines IL12 and TNFα.


ABSTRACT:

Introduction

Fragile X Tremor and Ataxia Syndrome is a progressive neurodegenerative disorder that develops in some FMR1 premutation carriers. The objective of this study is to characterize how cytokine levels are altered in the FXTAS brain.

Methods

Fresh frozen cerebellar tissue from FXTAS cases and controls was homogenized and analyzed for 12 different cytokines using a commercially available ELISA panel.

Results

Relative to controls, FXTAS cases showed large and significant increases in the cytokines IL-12 and TNFα. There were large but non-significant increases in the levels of IL-2, IL-8, and IL-10 in FXTAS cases. The cytokines IL-1A, IL-1B, IL-4 IL-6, IL-17A, IFNγ, and GM-CSF were not different between FXTAS and control subjects.

Conclusions

For the first time, we demonstrate an increase in the pro-inflammatory cytokines TNFα and IL-12 in the FXTAS brain, both of which are implicated in the pathogenesis of Multiple Sclerosis, another neurodegenerative disorder that predominantly consists of white matter disease.
