Astrocytes play vital roles in blood-brain barrier (BBB) maintenance, yet how they support BBB integrity under normal or pathological conditions remains poorly defined. Recent evidence suggests that ion homeostasis is a cellular mechanism important for BBB integrity. In the current study, we investigated the function of an astrocyte-specific pH regulator, Slc4a4, in BBB maintenance and repair.

Article Synopsis
  • This study investigates the role of the protein CMTM5 in demyelination and autoimmune diseases like multiple sclerosis (MS), revealing a reduction in its expression in MS lesions.
  • Research using animal models shows decreased CMTM5 levels in oligodendrocytes during demyelination processes, suggesting it plays a role in maintaining axonal integrity rather than myelin production.
  • Experiments with a mouse cell line indicate that knocking down CMTM5 does not affect responses to endoplasmic reticulum stress, highlighting the need for further research on its function in axonal degeneration related to demyelinating diseases.

While our knowledge of gene expression in different human cell types is rapidly expanding with advances in transcriptomic profiling technologies, the next challenge is to understand gene function in each cell type. CRISPR-Cas9-based functional genomics screening offers a powerful approach to determine gene function in a high-throughput manner. With the maturation of stem cell technology, a variety of human cell types can be derived from human pluripotent stem cells (hPSCs).

Maternal immune activation (MIA) is closely related to the onset of autism-like behaviors in offspring, but the mechanism remains unclear. Maternal behaviors can influence offspring's development and behaviors, as indicated in both human and animal studies. We hypothesized that abnormal maternal behaviors in MIA dams might be other factors leading to delayed development and abnormal behaviors in offspring.

There is an urgent need for therapies that target the multicellular pathology of central nervous system (CNS) disease. Modified, nonanticoagulant heparins mimic the heparan sulfate glycan family and are known regulators of multiple cellular processes. In vitro studies have demonstrated that low sulfated modified heparin mimetics (LS-mHeps) drive repair after CNS demyelination.

Article Synopsis
  • Microglia are the primary immune cells in the central nervous system, playing a crucial role in understanding neurodegenerative and neuroinflammatory diseases, but it's important to distinguish them from peripheral macrophages.
  • The study investigates TMEM119, a proposed microglial marker, in various disease models and post mortem analysis of multiple sclerosis, revealing that TMEM119 expression decreases when microglia experience stress.
  • The findings indicate that TMEM119 is not a reliable exclusive marker for microglia, suggesting caution when using TMEM119-based transgenic models in research.

Ectopic lymphoid follicles (ELFs), resembling germinal centre-like structures, emerge in a variety of infectious and autoimmune and neoplastic diseases. ELFs can be found in the meninges of around 40% of the investigated progressive multiple sclerosis (MS) post-mortem brain tissues and are associated with the severity of cortical degeneration and clinical disease progression. Of predominant importance for progressive neuronal damage during the progressive MS phase appears to be meningeal inflammation, comprising diffuse meningeal infiltrates, B-cell aggregates and compartmentalized ELFs.

Article Synopsis
  • Multiple sclerosis (MS) causes inflammation and damage to the central nervous system, leading to periods of myelin repair, but some tissue damage can still persist.
  • In a study using mice, researchers induced acute demyelination and found that although myelin and oligodendrocyte levels returned to normal after recovery, axonal degeneration and glial cell activation continued in the brain's corpus callosum.
  • The study also revealed increased inflammation-related gene activity, suggesting that sustained damage from microglia and macrophages contributes to ongoing neurodegeneration and functional decline in MS patients.

The loss of myelinating oligodendrocytes is a key characteristic of many neurological diseases, including Multiple Sclerosis (MS). In progressive MS, where effective treatment options are limited, peripheral immune cells can be found at the site of demyelination and are suggested to play a functional role during disease progression. In this study, we hypothesize that metabolic oligodendrocyte injury, caused by feeding the copper chelator cuprizone, is a potent trigger for peripheral immune cell recruitment into the central nervous system (CNS).

Background: An important hallmark of Alzheimer's disease (AD) is the increase of Aβ1-42 burden and its accumulation to senile plaques, leading the reactive gliosis and neurodegeneration. The modulation of glia cell function represents an attractive therapeutic strategy, but is currently limited by an incomplete understanding of its relevance for AD. The chemotactic G-protein coupled formyl peptide receptor (FPR), which is known to modulate Aβ1-42 uptake and signal transduction, might be one candidate molecule regulating glia function in AD.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system. Various pre-clinical models with different specific features of the disease are available to study MS pathogenesis and to develop new therapeutic options. During the last decade, the model of toxic demyelination induced by cuprizone has become more and more popular, and it has contributed substantially to our understanding of distinct yet important aspects of the MS pathology.

Experimental autoimmune encephalomyelitis (EAE) is the most commonly used multiple sclerosis animal model. EAE mice typically develop motor deficits in a caudal-to-rostral pattern when inflammatory lesions have already developed. However, to monitor more subtle behavioral deficits during lesion development (i.

Article Synopsis
  • Recent evidence indicates that brain degeneration may lead to the formation of inflammatory lesions in Multiple Sclerosis (MS).
  • A pre-clinical study using mice showed that treating with Laquinimod during induced brain degeneration (from cuprizone) significantly reduced inflammation and immune cell recruitment compared to untreated mice.
  • The findings suggest that addressing primary brain degeneration could prevent the secondary immune response and inflammatory damage, impacting how clinical MS treatments are understood.

Oligodendrocyte degeneration is a hallmark of multiple sclerosis pathology, and protecting oligodendrocytes and myelin is likely to be of clinical relevance. Traditionally, oligodendrocyte and myelin degeneration are viewed as a direct consequence of an inflammatory attack, but metabolic defects might be equally important. Appropriate animal models to study the interplay of inflammation and metabolic injury are, therefore, needed.

Oligodendrocytes are integral to efficient neuronal signaling. Loss of myelinating oligodendrocytes is a central feature of many neurological diseases, including multiple sclerosis (MS). The results of neuropathological studies suggest that oligodendrocytes react with differing sensitivity to toxic insults, with some cells dying early during lesion development and some cells being resistant for weeks.

Axonal damage is a major factor contributing to disease progression in multiple sclerosis (MS) patients. On the histological level, acute axonal injury is most frequently analyzed by anti-amyloid precursor protein immunohistochemistry. To what extent this method truly detects axonal injury, and whether other proteins and organelles are as well subjected to axonal transport deficits in demyelinated tissues is not known.
