Overview
Cíl:
Poškození neuronů u roztroušené sklerózy (RS) může být doprovázeno uvolňováním cytoskeletálního tau proteinu, který interaguje s narušenými složkami imunitního systému za vzniku autoprotilátek. Koncentrace tau proteinu mohou být ovlivněny přítomností protilátek proti tau proteinu v séru a mozkomíšním moku (MMM).
Metody:
Tau protein i protilátky proti tau proteinu jsme stanovovali pomocí metod ELISA u 31 pacientů (14 pacientů s RS a 17 kontrolních neurologických pacientů). Vypočítali jsme tři poměry tau proteinu vztahující se ke koncentraci a) anti-tau protilátek v MMM, b) anti-tau protilátek v séru a c) intratékálně produkovaných anti-tau protilátek.
Výsledky:
Neprokázali jsme statisticky významné korelace mezi koncentracemi tau proteinu a protilátek proti tau proteinu v séru, v MMM ani anti-tau protilátek intratékálně produkovaných. Koncentrace tau proteinu v MMM ani žádný z vypočtených poměrů se nelišily mezi skupinou pacientů s RS a kontrolních pacientů.
Závěr:
Uvolňování tau proteinu do MMM a protilátková odpověď proti tau proteinu u RS jsou zřejmě na sobě nezávislé procesy, podobně jako u jiných neurologických pacientů.
Klíčová slova:
tau protein – autoprotilátky – mozkomíšní mok – roztroušená skleróz
