Acupuncture modulates actin homeostasis and promotes myelin sheath regeneration in rat models of intracerebral hemorrhage.

The relationship between actin dynamics and remyelination after intracerebral hemorrhage (ICH) remains unclear. This study aims to investigate the mechanism by which scalp acupuncture (SA) regulates remyelination in acute ICH rats through the PAK1/LIMK1/CFL1 signaling pathway. The Male Sprague-Dawley rats were used to establish the ICH model by autologous blood injection. The treatment group SA intervention, with the selective inhibitor of PAK1, IPA-3, used as a positive control. The regulatory effect of SA on the PAK1/LIMK1/CFL1 signaling pathway after ICH was evaluated using neurological fun…

Разработка доклинической платформы человека для идентификации нетронутых охранных соединений.

Множественный склероз (MS) является наиболее распространенным воспалительным и демиелинизирующим заболеванием, влияющим на центральную нервную систему (КНС). В то время как иммуномодилизующие препараты могут предотвратить новые повреждения, реагируя на лимфоцитную активность, лечение не зависящих от рецидива заболеваний по-прежнему сопряжено с трудностями. Продолжительная воспаление CNS, приводящее к аксоновому и нейронному повреждению, а также к отсутствию компенсационных механизмов, таких, как пластичность мозга и воспаление, стимулирует развитие болезни. Таким образом, срочно необходимо иде

Новая потенциальная ось лиганда-рецептора, связанная с ремонтом тканей в качестве терапевтических целей в прогрессивном множественном склерозе.

Прогрессивный множественный склероз (MS) представляет собой ухудшающуюся фазу заболевания, характеризующуюся увеличением нейродегенерации и инвалидностью и главным образом отказом от текущего лечения. Поиск вариантов лечения по-прежнему сопряжен с определенными трудностями не только из-за отсутствия понимания патогенных механизмов, но и из-за того, что ранние догмы были сосредоточены на нейроинфламмации, что затмевало важнейшую роль процесса ремонта тканей. Цель по ремонту тканей должна начинаться на раннем этапе развития болезней, а терапевтические стратегии для прогрессивных MS должны сочета

Lipid Nanoparticles Vectorized with NFL-TBS.40-63 Peptide Target Oligodendrocytes and Promote Neurotrophin-3 Effects After Demyelination In Vitro.

Promoting remyelination in multiple sclerosis is important to prevent axon degeneration, given the lack of curative treatment. Although some growth factors improve this repair, unspecific delivery to cells and potential side effects limit their therapeutic use. Thus, NFL-TBS.40-63 peptide (NFL)-known to enter specifically myelinating oligodendrocytes (OL)-was used to vectorize 100 nm diameter lipid nanoparticles (LNC), and the ability of NFL-LNC to specifically target OL from newborn rat brain was assessed in vitro. Specific uptake of DiD-labeled NFL-LNC by OL characterized by CNP and myelin b…

Intervention with the LINGO-1 antibody could attenuate impaired spatial memory deficits by remyelination, which suggested that myelin injury was involved in spatial memory deficits and remyelination may be a potential therapeutic strategy in early stage of AD or mild cognitive impairments.

If the strong tendency for VEP latencies to shorten is due to ongoing remyelination, the lack of significant improvement in visual function may be because the visual deficit at 6 months is due to irreversible axonal loss rather than demyelination.

Demyelinating peripheral neuropathy in Devic disease.

This is a report of a 20-year-old man with typical features of Devic disease (neuromyelitis optica) associated with demyelinating peripheral neuropathy. A sural nerve biopsy showed markedly decreased myelinated fibers of a large diameter. Teased fiber preparations showed segmental remyelination in 50% of examined fibers, as well as a few demyelination. Demyelination of bilateral optic nerves, spinal cord, and peripheral nerves at the same time suggests a possibility of common pathogenetic mechanisms in both the central and peripheral nervous systems.

Insulinoma and subclinical peripheral neuropathy in two dogs.

Two dogs with diffuse, subclinical polyneuropathy associated with insulinoma are reported. Seizures were the dominant sign of central nervous system disease. One dog had clinical signs of facial nerve paralysis. Lesions in selected appendicular and cranial nerves included a mixture of demyelination, remyelination, and axonal degeneration. The incidence (range: 18-47%) of these changes far exceeded that of comparable nerves from six control dogs (range 0-11%). Myopathic and electrodiagnostic findings were compatible with the nerve changes.

This possibility was tested by inducing experimental autoimmune encephalomyelitis in older mice, at an age equivalent to that with increased risk of RRMS transition into PMS.

In addition, hucMSC-Exos also upregulated the ex …

Двойная роль микроглии в множественном склерозе и его последствия для диагностики и ремонта.

Микроглия играет ключевую роль в развитии, иммунной слежке и восстановлении центральной нервной системы. Эти клетки играют многогранную роль в множестве склероза (MS), при этом есть основания полагать, что микроглия может способствовать как активному воспалению, так и воспалению. Например, было продемонстрировано, что микроглия может поддерживать разработку олигодендроцитов и фигоцитоза миелиновых обломков, способствуя тем самым надлежащему восстановлению. Однако чрезмерная активация микроглии в повреждениях MS усугубляет нейроинфламму, высвобождая подстрекательские цитокины и облегчая активац

Targeted Oligodendrocyte Apoptosis in Optic Nerve Leads to Persistent Demyelination.

The optic nerve represents one of the simplest regions of the CNS and has been useful in developing an understanding of glial development and myelination. While the visual system is frequently affected in demyelinating conditions, utilizing the optic nerve to model demyelination/remyelination studies has been difficult due to its accessibility, relatively small size, and dense nature that makes direct injections challenging. Taking advantage of the lack of oligodendrocytes and myelination in the mouse retina, we have developed a model in which the induction of apoptosis in mature oligodendrocy…

The spectrum of Charcot-Marie-Tooth disease due to myelin protein zero: An electrodiagnostic, nerve ultrasound and histological study.

OBJECTIVE: Nerve ultrasound (US) data on myelin protein zero (MPZ)-related Charcot-Marie-Tooth disease (CMT) are lacking. To offer a comprehensive perspective on MPZ-related CMTs, we combined nerve US with clinics, electrodiagnosis and histopathology. METHODS: We recruited 36 patients (12 MPZ mutations), and correlated nerve US to clinical, electrodiagnostic measures, and sural nerve biopsy. RESULTS: According to motor nerve conduction velocity (MNCV) criteria, nine patients were categorized as "demyelinating" CMT1B, 17 as "axonal" CMT2I/J, and 10 as dominant "intermediate" CMTDID. Sural ner

Non-demyelinating, reversible conduction failure in Fisher syndrome and related disorders.

BACKGROUND: IgG anti-GQ1b antibodies are associated with Fisher syndrome (FS), Bickerstaff brainstem encephalitis (BBE), acute ophthalmoparesis and overlap of FS or BBE with Guillain--Barré syndrome (GBS) (FS/GBS or BBE/GBS). It has not been clearly established if the primary pathology of these disorders is demyelinating or axonal in nature. Rapid resolution of conduction slowing or block without signs of demyelination--remyelination has been reported in axonal subtypes of GBS that are associated with IgG anti-GM1 or -GD1a antibodies. We hypothesised that such reversible conduction failure wou…
