Abstract

Introduction: Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) characterized by demyelination and brain pericyte dysfunction might be involved in MS pathogenesis Our aim was to evaluate whether the factors in serum affect pericyte survival. Method: C57BL/6 female mice were immunized with myelin oligodendrocyte glycoprotein (MOG) to induce experimental autoimmune encephalomyelitis (EAE). To confirm the animal model, the sera level of anti-MOG antibody in mice and platelet-derived growth factor-BB (PDGF-BB) in patients was measured by ELISA. Human brain vascular pericytes (HBVP) cell lines were incubated with sera of EAE mice and primer progressive MS (PPMS), seconder progressive MS (SPMS) and relapsing-remitting MS (RRMS) patients. The viability of HBVP is measured with Annexin V-FITC/propidium iodide staining with flow cytometry. Results: Annexin V-FITC/propidium iodide staining with flow cytometry showed increased ratios of early apoptosis and decreased survival following incubation with sera of EAE and progressive MS. Levels of platelet-derived growth factor-BB were identical in serum and cerebrospinal fluids of patients with different forms of MS. Conclusion: Our results suggest that serum factors might contribute to progressive MS pathogenesis via pericyte dysfunction.

Özet

Amaç: Multipl skleroz (MS) merkezi sinir sisteminin (MSS) otoimmündemiyelinizan hastalığıdır. Son yıllardaki bulgular beyin perisitdisfonksiyonunun MS patogenezinde yol oynayabileceğini göstermiştir.Bu çalışmada amacımız MS’nin perisit sağkalımına etkilerini ortayakoymaktır.Yöntem: MS hayvan modeli olan deneysel otoimmün ensefalomiyelit(DOE) modelini oluşturmak için, 8–10 haftalık C57BL/6 dişi fareler miyelinoligodendrosit glikoprotein (MOG) ile immünize edildi. Deneysel hayvanmodelinin başarılı bir şekilde oluştuğunu doğrulamak için fareler klinikolarak gözlemlendi ve kanları alınarak serumlarında anti-MOG antikorutaraması yapıldı. Hücre kültürü ortamında, insan beyin damarsal perisit(İBDP) ile DOE fare ve insan MS hastası serumları (yineleyici MS, sekonderprogresif MS ve primer progresif MS hastaları dâhil edilmiştir.) Yirmi dörtsaat inkübe edildi. Perisitlerin hücresel canlılık durumu Annexin V-FITC/propidiyum iyodid (PI) ile akım sitometrisinde değerlendirildi. Ayrıca MShastaları serumunda perisitlerin fonksiyonu için önemli olan trombositkaynaklı büyüme faktörü düzeyi ELISA yöntemi ile ölçüldü.Bulgular: DOE ve progresif tip MS serumları ile inkübe olan perisitlerindiğer gruplara göre anlamlı derecede yüksek oranlarda erken apoptozagirdiği ve buna bağlı olarak canlılık yüzdelerinin düştüğü görülmüştür.Farklı MS tiplerine sahip hasta ve sağlıklı kontrollerin serum ve beyinomurilik sıvılarındaki trombosit-kaynaklı büyüme faktörü seviyeleriaçısından anlamlı bir fark bulunmadı.Sonuç: Elde ettiğimiz bulgular progresif tip MS hastalarınınserumlarındaki birtakım faktörlerin perisit disfonksiyonuna sebep olarakMS patogenezine katkı yaptığını düşündürmektedir.
