Abstract

Introduction: Th17 cells are critical mediators of pathology in several autoimmune diseases including multiplesclerosis (MS). The aim of this study was to quantify Th17 cells and-associated cytokines in the peripheral blood ofrelapsing remitting multiple sclerosis patients (RRMS). We also aimed to compare those levels in fingolimod-treated,and untreated patients.Material and Methods: Fifteen fingolimod administered RRMS, 9 untreated-RRMS patients and 6 healthy controlswere evaluated. Their peripheral blood mononuclear cells (PBMCs) were isolated and sera separated. IL $-17A^+$, IL-$22^+$and GM-$CSF^+$ T-cells were quantified via intracellular cytokine staining after stimulation using flouresecein activatedcell sorter. Serum cytokine levels from all groups were measured via enzyme-linked immunosorbent assay (ELISA).Results: Fingolimod-treated RRMS patients had reduced number of IL $17A^+$ (p=0.02), IL-$22^+$ (p=0.05), and $GMCSF^+$ (p=0.003) T cells in their peripheral blood compared to those of untreated RRMS patients. This is consistentwith sequestration of lymphocytes in the secondary lymphoid organs after fingolimod use. However, the levels of samecytokines in the serum were statistically not different.Conclusions: Fingolimod treatment reduced circulating IL$17A^+$, IL-$22^+$ or GM-$CSF^+$ T cells in RRMS patients.

Özet

Th17 hücreleri, multipl sklerozun da dahil olduğu birçok otoimmün hastalığın patogenezinde rol alan kritik bir hücre popülasyonudur. Bu çalışmada, fingolimod tedavisi alan ve almayan tekrarlayan-gerileyen multipl sklerozlu (TGMS) hastalarının kanındaki Th17 hücre sayısı ve ilişkili sitokinlerin miktarlarını irdelemeyi amaçladık. Gereç ve Yöntemler: On beş fingolimod tedavisi alan TGMS hastası, ve tedavi almayan 9 TGMS hastası ile 6 sağlıklı kontrol çalışmaya dahil edildi. Kandan izole edilen periferik kan mononükleer hücreleri stimüle edilmiş, intraselüler hücre boyaması ve FACSAriaIII kullanılarak IL-17A, IL-22 ve GM-CSF üreten T hücreleri sayı ve yüzdeleri ölçüldü. Serum sitokin seviyeleri ELISA yöntemi ile saptandı. Bulgular: Fingolimod tedavisi alan RRMS hastalarının kanındaki IL-$-17A^+$(p=0,02), IL$22^+$(p=0,05), GM-$CSF^+$ (p=0,003) T hücrelerinin mutlak sayılarında, fingolimod almayan TSMS hastalarına göre, önemli ölçüde azalma gözlendi. Bu sonuç fingolimod’un lenfositleri sekonder lenfoid organlarda tutma mekanizması ile uyumludur. ELISA ile serumdan ölçülen aynı sitokinlerin seviyerinde anlamlı azalma gözlenmedi. Sonuç: Fingolimod dolaşımdaki IL-$-17A^+$ , IL-$22^+$ve GM-$CSF^+$üreten T hücre sayılarını azaltmaktadır.
