A dietary intervention with conjugated linoleic acid enhances microstructural white matter reorganization in experimental stroke.

Background: A dietary supplementation with conjugated linoleic acid (CLA) was shown to attenuate inflammation and increase the proportions of circulating regulatory T cells (T) and M2-type macrophages in disease models such as autoimmune encephalitis and arteriosclerosis. Since T and anti-inflammatory (M2-type) macrophages were found to enhance stroke recovery, we hypothesized that CLA-supplementation might improve stroke recovery via immune modulatory effects.

Methods: Functional assessment was performed over 90 days after induction of experimental photothrombotic stroke in wild type mice ( = 37, sham  = 10).

[Inflammatory causes of stroke-Diagnostics and treatment].

Inflammatory causes of stroke are frequent and often pose diagnostic and therapeutic challenges due to the scarcity of randomized trials and the absence of clear guideline recommendations for many scenarios. Following the publication of the recommendations of the European Stroke Organization on primary angiitis of the central nervous system (PACNS) last year, the German Neurological Society (DGN) has issued very clear guidelines this year on the diagnostics and treatment of PACNS and updated the recommendations for systemic vasculitides; however, stroke often occurs not only as a result of primary vascular inflammation but also as a complication of another organ infection. Approximately 5% of all patients with sepsis, ca.

Anti-LINGO-1 treatment restores myelination of corticospinal tract neurons and improves functional recovery after stroke.

Demyelination of corticospinal tract neurons contributes to long-term disability after cortical stroke. Nonetheless, poststroke myelin loss has not been addressed as a therapeutic target, so far. We hypothesized that an antibody-mediated inhibition of the Nogo receptor-interacting protein (LINGO-1, leucine-rich repeat and immunoglobulin domain-containing Nogo receptor-interacting protein) may counteract myelin loss, enhance remyelination and axonal growth, and thus promote functional recovery following stroke.

Inhibition of leukocyte migration after ischemic stroke by VE-cadherin mutation in a mouse model leads to reduced infarct volumes and improved motor skills.

Aims: To distinguish between the genuine cellular impact of the ischemic cascade by leukocytes and unspecific effects of edema and humoral components, two knock-in mouse lines were utilized. Mouse lines Y731F and Y685F possess point mutations in VE-cadherin, which lead to a selective inhibition of transendothelial leukocyte migration or impaired vascular permeability.

Methods: Ischemic stroke was induced by a model of middle cerebral artery occlusion.

EXERTION: a pilot trial on the effect of aerobic, smartwatch-controlled exercise on stroke recovery: effects on motor function, structural repair, cognition, mental well-being, and the immune system.

Introduction: Motor impairments are the objectively most striking sequelae after stroke, but non-motor consequences represent a high burden for stroke survivors as well. Depression is reported in one third of patients, the fatigue prevalence ranges from 23 to 75% due to heterogenous definitions and assessments. Cognitive impairment is found in one third of stroke patients 3-12 months after stroke and the risk for dementia is doubled by the event.

Cytotoxic corpus callosum lesion and mild CSF pleocytosis during hantavirus infection: a case report.

A middle-aged, previously healthy male patient presented with high fever, headache, and aching limbs for 3 days. Laboratory results showed signs of acute kidney injury, elevated procalcitonin, and mild thrombocytopenia. On neurological examination, he had no focal neurological deficits, especially no meningism or visual disturbances.

Deficiency of the Two-Pore Potassium Channel KCNK9 Impairs Intestinal Epithelial Cell Survival and Aggravates Dextran Sodium Sulfate-Induced Colitis.

Background & Aims: The 2-pore potassium channel subfamily K member 9 (KCNK9) regulates intracellular calcium concentration and thus modulates cell survival and inflammatory signaling pathways. It also was recognized as a risk allele for inflammatory bowel disease. However, it remains unclear whether KCNK9 modulates inflammatory bowel disease via its impact on immune cell function or whether its influence on calcium homeostasis also is relevant in intestinal epithelial cells.

Efficacy and safety of alemtuzumab versus fingolimod in RRMS after natalizumab cessation.

Background: Natalizumab (NTZ) was the first approved monoclonal antibody for the treatment of relapsing-remitting multiple sclerosis (RRMS). Despite proven and sustained efficacy, its use is limited by the risk of progressive multifocal leukoencephalopathy (PML). Moreover, some patients show ongoing disease activity under NTZ, requiring a switch to another disease-modifying treatment (DMT).
