Multiple sclerosis (MS) is a chronic, progressive, inflammatory and degenerative disease of central nervous system. Here, we aimed to develop a method for differential diagnosis of Relapsing-Remitting MS (RRMS) and clinically isolated syndrome (CIS) patients, as well as to identify CIS patients who will progress to RRMS, from cerebrospinal fluid (CSF) by infrared (IR) spectroscopy and multivariate analysis. Spectral analyses demonstrated significant differences in the molecular contents, especially in the lipids and Z conformation of DNA of CSF from CIS, CIS to RRMS transformed (TCIS) and RRMS groups. These changes enables the discrimination of diseased groups and controls (individuals with no neurological disease) from each other using hierarchical cluster and principal component analysis. Some CIS samples were consistently clustered in RRMS class, which may indicate that these CIS patients potentially will transform to RRMS over time. Z-DNA band at 795 cm(-1) that is existent only in diseased groups and significant increase in carbonyl amount, decrease in amideI/amide II and lipid/protein ratios observed only for RRMS groups can be used as diagnostic biomarkers. The results of the present study shed light on the early diagnosis of RRMS by IR spectroscopy complemented with multivariate analysis tools.

Multiple Sclerosis (MS) is an autoimmune disease characterized by inflammation, demyelination, and axonal damage resulting in neurodegeneration in the central nervous system (CNS). Relapsing-remitting MS (RRMS) is the most common form of the disease known to affect more than 2 million individuals globally, and the prevalence of the disease is increasing worldwide. As a chronic condition without a cure, RRMS manifests in a relapsing-remitting form with sporadic attacks suddenly appearing, causing neurologica...

Multiple sclerosis (MS) is a complicated, recurrent, and often progressive inflammatory demyelinating autoimmune disease of the central nervous system, yet etiopathogenesis remains unsolved. MS frequency increases with increasing latitude, leading to a hypothesis that MS is inversely correlated with the duration and intensity of sunlight and vitamin D concentrations. In this study, the relationships between vitamin D supplementation, MS, VDR, and vitamin D metabolizing CYP enzymes, including CYP2R1, CYP27A1...
Investigation of Glutathione S-Transferase (GST) expression and activity in mouse with Multiple Sclerosis (MS)

Multiple Sclerosis (MS) of unknown etiopathogenesis is a chronic demyelinating disease of the central nervous system. It mainly destroys myelin in the brain and spinal cord. Non-traumatic injuries have been observed in this disease for young adults. Various factors affect MS, but oxidative stress is one of the most important causes of demyelination. Glutathione S- Transferases (GSTs) can be described as a versatile enzyme family of eukaryotic and prokaryotic phase II metabolic isoenzymes. They have enzymati...
Generation and characterization of human induced pluripotent stem cell line METUi001-A from a 25-year-old male patient with relapsing-remitting multiple sclerosis

Multiple sclerosis is a chronic disease characterized by inflammation, demyelination, and axonal damage in the central nervous system. Here, we established an induced pluripotent stem cell (iPSC) line METUi001-A from the peripheral blood mononuclear cells of a 25-year-old male individual with clinically diagnosed Relapsing-Remitting Multiple Sclerosis (RRMS) using the integration-free Sendai reprogramming method. We demonstrated that the iPSCs are free of exogenous Sendai reprogramming vectors, have a norma...
Impaired inhibitory GABAergic synaptic transmission and transcription studied in single neurons by Patch-seq in Huntington's disease

Transcriptional dysregulation in Huntington's disease (HD) causes functional deficits in striatal neurons. Here, we performed Patchsequencing (Patch-seq) in an in vitro HD model to investigate the effects of mutant Huntingtin (Htt) on synaptic transmission and gene transcription in single striatal neurons. We found that expression of mutant Htt decreased the synaptic output of striatal neurons in a cell autonomous fashion and identified a number of genes whose dysregulation was correlated with physiological...
