The 18.5 kDa myelin basic protein (MBP), the most abundant splice isoform in human adult myelin, is a multifunctional, intrinsically disordered protein that maintains compact assembly of the myelin sheath in the central nervous system. Protein deimination and phosphorylation are two key posttranslational modifications whose balance determines local myelin microdomain stability and function. It ...

The transcriptional program that controls oligodendrocyte maturation and central nervous system (CNS) myelination has not been fully characterized. In this study, we use high-throughput RNA sequencing to analyze how the loss of a key transcription factor, zinc finger protein 191 (ZFP191), results in oligodendrocyte development abnormalities and CNS hypomyelination. Using a previously described ...

Central tolerance plays a critical role in eliminating self-reactive T cells specific for peripheral antigens. Here we show that central tolerance of MHC class I-restricted T cells specific for classic myelin basic protein (MBP), a component of the myelin sheath, is mediated by both bone marrow (BM)-derived and nonBM-derived cells. Unexpectedly, BM-derived cells induce tolerance directly by usi...

Oral administration of antigen is a long recognized method of inducing systemic immune tolerance. In animals with experimental autoimmune disease, a major mechanism of oral tolerance triggered by oral administration of antigen involves the induction of regulatory T cells that mediate active suppression by secreting the cytokine TGF-beta 1. Multiple sclerosis (MS) is a presumed T cell-mediated T...

Autism is a neurodevelopmental behavioral disorder with unknown etiology characterized by impairment of social contact and communication, restricted and repetitive interest and behaviors. The aim of the current study is to explore possible role of Brain-derived neurotrophic factor (BDNF) and serum myelin basic protein (MBP) auto-antibody in autism spectrum disorders. The study was conducted at ...

The MB1 regulatory sequence of the myelin basic protein (MBP) gene spanning between nucleotides -14 to -50 with respect to the transcription start site is critical for cell type-specific transcription of the MBP gene, which encodes the major protein component of myelin sheath in cells derived from the central nervous system (CNS). This regulatory sequence has the ability to interact with a deve...

The interaction of myelin basic protein (MBP) from the bovine central nervous system with Ca2+ and Mg2+ ions, named as M2+, was studied by isothermal titration calorimetry at 27 degrees C in aqueous solution. The extended solvation model was used to reproduce the enthalpies of MBP+M2+ interactions. The solvation parameters recovered from the extended solvation model were attributed to the struc...

More than 50% of multiple sclerosis patients develop cognitive impairment. However, the underlying mechanisms are still unclear, and there is no effective treatment. LINGO-1 (LRR and Ig domain containing NOGO receptor interacting protein 1) has been identified as an inhibitor of oligodendrocyte differentiation and myelination. Using the experimental autoimmune encephalomyelitis (EAE) mouse mode...

Precise control of oligodendrocyte migration and development is crucial for myelination of axons in the central nervous system (CNS), but important questions remain unanswered about the mechanisms controlling these processes. In a zebrafish screen for myelination mutants, we identified amutation in zinc finger protein 16-like (znf16l). znf16l mutant larvae have reduced myelin basic protein (mbp...
