Abstract

DOI: 10.26650/experimed.2019.19026 Objective: Multiple Sclerosis (MS) is a progresive and an immune mediated inflammatory central nervous disease. The focus of this study was to determine the possible relationship between B cell immunophenotypes and related gene expressions in the benign MS (BMS) group with disease and cognitive processes. Material and Method: Twenty BMS patients, 16 non-BMS and 28 healthy volunteers were included in the study. Gene expression was performed by real-time PCR (RT-PCR). Immunophenotyping of peripheral B cells was also evaluated by flow cytometry. The relationship between cognitive functions and gene expression levels and B cell subtypes was investigated. Results: It was observed that naïve (CD19+ IgD+CD27-) cells were higher in the BMS group compared to the healthy group (HC), and memory B cells showed opposite changes. Un-switched memory B cells(CD19+IgD+CD27+) were found to be higher in the benign group than in the HC. The expression of BANK and BLNK was found to be lower in both MS groups than in the HC. As a result of neuropsychological examinations and cognitive tests; it was observed that motor processes in BMS were better protected than Non-BMS. Conclusion: These findings support that B cell functions may have molecular and cellular effects, and may lead to regression in inflammation and clinical progression. Molecules showing significant changes in our study may play a role as prognostic biomarkers in MS. Cite this article as: Şen M, Akbayır E, Türkoğlu R, Tüzün E, Yılmaz V.

Özet

DOI: 10.26650/experimed.2019.19026 Amaç: Multipl Skleroz (MS), aksonal dejenerasyona, demiyelinizasyona ve inflamasyona bağlı gelişen, merkezi sinir sistemini etkileyen progresif bir hastalıktır. Bu çalışmada benign MS (BMS) grubunda periferik kan B hücre immünofenotiplerinin ve B hücresi ile ilişkili gen ekspresyonlarının hastalık ve bilişsel süreçlerle ilişkisinin araştırılması hedeflenmiştir. Gereç ve Yöntem: Yirmi BMS hastası, 16 benign olmayan MS (Non-BMS) hastası ve 28 sağlıklı gönüllü çalışmaya dahil edildi. Daha önce periferik kan hücrelerinde yapılan gen mikroarray çalışması ile gruplar arasında ekspresyonu değişikliği gözlenen genlerin validasyonu gerçek zamanlı PZR ile yapıldı. Periferik B hücrelerinin immünofenotiplemesi akım sitometrisi ile değerlendirildi. Bilişsel fonksiyonlar ile gen ekspresyon seviyeleri ve B hücre alttipleri arasındaki olası ilişki araştırıldı. Bulgular: Naif (CD19+ IgD+CD27-) B hücrelerinin BMS grubunda sağlıklılara göre yüksek olduğu, hafıza B hücrelerinin zıt yönde değişiklik gösterdiği gözlendi. Dönüşmemiş hafıza B hücrelerinin (CD19+IgD+CD27+) ise benign grupta sağlıklılara göre yüksek olduğu belirlendi. BANK ve BLNK gen ekspresyonları her iki MS grubunda da sağlıklılardan düşük olarak belirlendi. Nöropsikolojik incelemeler ve kognitif testler sonucunda, BMS’te motor süreçlerin Non-BMS’ye göre korunduğu gözlendi. Sonuç: Bu bulgular B hücresi işlevlerinin moleküler ve hücresel etkileri olabileceği ve inflamasyon ile klinik progresyonda gerilemeye yol açabileceği yönündeki görüşleri desteklemektedir. Değişiklik gösteren moleküllerin MS hastalığında prognostik biyobelirteç olarak rol oynaması da mümkündür. Cite this article as: Şen M, Akbayır E, Türkoğlu R, Tüzün E, Yılmaz V.
