Britta Engelhard’s research is devoted to understanding thefunction of the different brain barriers in regulating CNS immunesurveillance and how their impaired function contributes toneuroinflammatory diseases such as Multiple Sclerosis (MS) orAlzheimer’s disease (AD). Her laboratory combines expertise invascular biology, neuroimmunology and live cell imaging and hasdeveloped sophisticated in vitro and in vivo approaches to studyimmune cell interactions with the brain barriers in health andneuroinflammation.

Microglia are the resident CNS macrophages of the brain parenchyma. They have many and opposing roles in health and disease, ranging from inflammatory to anti-inflammatory and protective functions, depending on the developmental stage and the disease context. In Multiple Sclerosis, microglia are involved to important hallmarks of the disease, such as inflammation, demyelination, axonal damage and remyelination, however the exact mechanisms controlling their transformation towards a protective or devastating phenotype during the disease progression remains largely unknown until now. We wish to

Current disease-modifying therapies in multiple sclerosis are all focused on suppressing the inflammatory phase of the disease. This has been extremely successful, and it is doubtful that significantly more efficacious anti-inflammatory treatments will be found. However, it remains the case that people with relapsing-remitting multiple sclerosis acquire disability on treatment, and enter the secondary progressive phase. I argue that we now need treatments that prevent neuronal degeneration. The most promising approach is to prevent axons degenerating by remyelination. Since the discovery that

Our goal is to understand why myelin repair fails in multiple sclerosis and to develop regenerative medicines for the nervous system. A central obstacle for progress in this area has been the complex biology underlying the response to CNS injury. Acute CNS damage is followed by a multicellular response that encompasses different cell types and spans different scales. Currently, we do not understand which factors determines lesion recovery. Failure of inflammation to resolve is a key underlying reason of poor regeneration, and one focus is therefore on the biology of microglia during de- and re

There are currently no approved therapies to slow down the accumulation of neurological disability that occurs independently of relapses in multiple sclerosis (MS). International agencies are engaging to expedite the development of novel strategies capable of modifying disease progression, abrogating persistent CNS inflammation, and support degenerating axons in people with progressive MS. Understanding why regeneration fails in the progressive MS brain and developing new regenerative approaches is a key priority for the Pluchino Lab. In particular, we aim to elucidate how the immune system, i

The normally functioning blood-brain barrier (BBB) regulates the transfer of material between blood and brain. BBB dysfunction has long been recognized in multiple sclerosis (MS), and there is considerable interest in quantifying functional aspects of brain blood vessels and their role in disease progression. Parenchymal water content and its association with volume regulation is important for proper brain function, and is one of the key roles of the BBB. There is convincing evidence that the astrocyte is critical in establishing and maintaining a functional BBB and providing metabolic support

We recently analyzed a large cohort of multiple sclerosis (MS) autopsy cases of the Netherlands Brain Bank (NBB) and showed that 57% of the lesion in advanced MS is active (containing activated microglia/macrophages). These active lesions correlated with disease severity and differed between males and female MS patients.1 Already in normal appearing white matter microglia show early signs of demyelination.5 T cells are also frequently present in advanced stages of MS and have a tissue resident memory (Trm) phenotype, are more frequently CD8+ then CD4+, are located perivascular, enriched in act

Electrophysiology of eye and visual pathway is useful tool in ophthalmology and neurology. It covers a few examinations to find out if defect of vision is peripheral or central. Visual evoked potentials (VEP) are most frequently used in neurology and neuroophthalmology. VEP are evoked by flash or pattern stimulations. The combination of these both examinations gives more information about the visual pathway. It is very important to remember that VEP originate in the retina and reflect its function as well. In many cases not only VEP but also electroretinography (ERG) is essential for diagnosi

Experimental autoimmune encephalomyelitis (EAE) is a laboratory model for multiple sclerosis (MS), an autoimmune disease characterized by chronic inflammation in the CNS, associated with demyelination and neurological disorders. Dysbiosis of the gut microbiota is a risk factor for MS. Probiotic strains can modulate the microbiota composition and are considered a therapeutic approach for MS.This study aimed to explore the therapeutic potential of Enterococcus faecium L-3 (E.faecium), a probiotic strain, in modulating gut microbiota, intestinal morphology, and immune responses within an EAE rat

Multiple Sclerosis (MS) is a chronic inflammatory disorder of the central nervous system. Despite advancements in diagnostic methods, early detection remains challenging. Metabolomic analysis offers a promising, non-invasive approach to identify potential biomarkers for improved diagnostic precision.Cerebrospinal fluid (CSF) and serum samples from 24 healthy controls, 48 MS patients, and 20 Non-MS patients with a range of diverse conditions, including infections, autoimmune disorders, inflammatory issues, and other neurological disorders were collected during lumbar puncture. NMR analysis on a

More pilot studies are emerging with the goal of contributing to the bigger puzzle of personalized multiple sclerosis (MS) therapies. This study aimed to examine the potential benefit of using four non-coding RNAs (ncRNAs) (miR-141, miR-9, MEG3, and IFNG-AS1) as prognostic and/or diagnostic biomarkers for MS. We also aimed to examine the relationship between two single nucleotide polymorphisms (SNPs), rs547311 and rs205764 on the long intergenic non-coding RNA (linc)-00513 gene (genotyping), and the expression levels of the aforementioned genes (qPCR), in addition to IFN-g (ELISA).
