| Multiple sclerosis (MS) is the most common inflammatory neurodegenerative disease. Neurofilament
light chain (NFL) is a novel adverting biomarker of axonal damage that suggested as a useful assistant
in the monitoring of MS patients. It has been shown that the auto/mitophagy associated with MS pathogenesis.
In this study, we aimed to study correlation between ATG5 and Parkin, as markers of autophagy
and mitophagy respectively, with NFL and ANT1 in serum and cerebrospinal fluid (CSF) in MS subjects.
ATG5, Parkin, NFL, and ANT1 levels were measured in a cross-sectional study of 40 MS patients compared
with gender, age and BMI matching healthy volunteers. Based on our results, levels of ATG5, Parkin, and
NFL significantly were elevated in both serum and CSF of MS patients comparing control individuals
(p < 0.0001) but ANT1 levels significantly was decreased in both serum and CSF of MS patients comparing
control individuals (p < 0.0001). The correlation indices between NFL, ANTI1, ATG5 and Parkin in both
case and control groups showed a direct and moderate the correlation between ANTI1 and ATG5 in
the CSF level of the control group (r = 0.554, P = 0.011). Our data support the feasibility of quantifying
of NFL as a sensitive and clinically meaningful serum/CSF biomarker to follow-up nerve tissue injury
in MS condition. |
