Progressive Elevation of Store-Operated Calcium Entry-Associated Regulatory Factor (SARAF) and Calcium Pathway Dysregulation in Multiple Sclerosis.

Multiple Sclerosis (MS) is a chronic autoimmune disorder characterized by demyelination and neuronal damage in the central nervous system. Dysregulation of calcium homeostasis, particularly through the Store-Operated Calcium Entry-Associated Regulatory Factor (SARAF), has been implicated in MS pathogenesis. This study investigated SARAF, STIM1, and Orai1 expression patterns and their relationship to calcium homeostasis in 45 Bahraini MS patients and 45 matched healthy controls using ELISA and real-time PCR analyses. MS patients showed significantly elevated serum SARAF levels in both early (19

Гипоксия в множестве склерозов.

Низкая доступность кислорода (гипоксии) является заметной, но плохо понимаемой особенностью множественного склероза (МС). Неизвестно, вызывает ли гипоксия патологию и симптомы MS или она является следствием других патологических явлений, таких, как воспаление и сосудистая дисфункция. Здесь мы резюмируем имеющуюся литературу о взаимосвязи между гипоксией и как патологическими, так и симптомными характеристиками MS. Острая экологическая гипоксия (т.е. высота) может вызвать или облегчить события, связанные с MS, возможно, путем усиления гипоксии тканей в центральной нервной системе. Соответственн

Amyloid Proteins and Peripheral Neuropathy.

Painful peripheral neuropathy affects millions of people worldwide. Peripheral neuropathy develops in patients with various diseases, including rare familial or acquired amyloid polyneuropathies, as well as some common diseases, including type 2 diabetes mellitus and several chronic inflammatory diseases. Intriguingly, these diseases share a histopathological feature-deposits of amyloid-forming proteins in tissues. Amyloid-forming proteins may cause tissue dysregulation and damage, including damage to nerves, and may be a common cause of neuropathy in these, and potentially other, diseases. He

Использование естественных экзоцитозных везикул для борьбы с возрастными заболеваниями: от возрастных драйверов до терапевтических возможностей.

Старение — это сложный биологический процесс, приводящий к увеличению нагрузки возрастных заболеваний (ARD). Клеточная старость, включающая необратимое остановку клеточного цикла и выделение фенотипа секреторной активности при старении (SASP), играет центральную роль в старении и развитии ARD. Естественные экзоцитические везикулы (NEVs) — это везикулы, полученные из клеток, органов и тканей без искусственных вмешательств. В последние годы NEVs привлекли внимание как медиаторы межклеточной коммуникации, и показали многофункциональный потенциал в регулировании клеточной старости и ARD. С одной с

Epigenetic Dysregulation in Neurodegeneration: The Role of Histone Deacetylases and Emerging Inhibitor Strategies.

Neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD) are characterized by complex pathologies with progressive neurodegeneration, protein misfolding, oxidative stress, and persistent inflammation. Recent findings indicate the pivotal involvement of epigenetic disruption, particularly aberrant histone deacetylase (HDAC) activity, in disease initiation and progression. In the current review, we systematically discuss the mechanistic function of HDACs across all classes (I, IIa, IIb, III, and IV) in neurodegenerative disease mechanis

Mechanisms and effects of metformin on skeletal muscle disorders.

Skeletal muscle disorders are mostly genetic and include several rare diseases. With disease progression, muscle fibrosis and adiposis occur, resulting in limited mobility. The long course of these diseases combined with limited treatment options affect patients both psychologically and economically, hence the development of novel treatments for neuromuscular diseases is crucial to obtain a better quality of life. As a widely used hypoglycemic drug in clinical practice, metformin not only has anti-inflammatory, autophagy-regulating, and mitochondrial biogenesis-regulating effects, but it has a

Биологическая роль мономеров традиционной китайской медицины в нейронных расстройствах.

Однако применение мономеров ТХМ ограничено их низкой растворимостью и низкой способностью пересекать барьер кровеносного мозга (ББД). Экзосомы представляют собой небольшие внеклеточные везикли (ЭМ) диаметром от 30 до 150 нм и могут использоваться в качестве носителей наркотиков, которые непосредственно предназначены дл

The potential of dibenzazepine carboxamides in cancer therapy.

Cancer is a leading cause of mortality worldwide, with most conventional treatments lacking efficacy and having significant challenges like drug resistance. Finding new molecules is quite challenging in terms of cost, time and setbacks. Hence, drug repurposing is considered sensible for skipping the long process of drug development. Dibenzazepine carboxamides, as traditional anticonvulsants, primarily function by blocking voltage-gated sodium channels, which not only mitigate seizures but also influence mood disorders through modulation of serotonin and dopamine. Recent studies have uncovered

Exosomes: A new option for osteoporosis treatment.

Osteoporosis is a systemic bone disease characterized by reduced bone mass and destruction of bone microarchitecture, leading to increased bone fragility and susceptibility to fracture. However, the pathogenesis and molecular mechanisms of this disease remain unclear. Extracellular vesicles, structures originating from the plasma membrane and ranging from 30 nm to 5 µm in diameter, play an important role in intercellular communication in the bone microenvironment. Exosomes are extracellular vesicles that deliver cargo molecules, including endogenous proteins, lipids and nucleic acids. These ca

Nonsteroidal Anti-Inflammatory Drugs as Modulators of Cation Channels: Fenamates Repurposing in Channelopathies.

Cationic ion channels are transmembrane proteins that regulate the flux of cations (potassium, sodium, and calcium) across cell membrane, playing a pivotal role in many cellular functions. Disruptions of their activity can lead to the so-called genetic or acquired channelopathies, a heterogeneous group of diseases that affect multiple human systems. Fenamates, a class of nonsteroidal anti-inflammatory drugs, has recently emerged as modulators of cationic ion channels highlighting the possibility of their repurposing for the treatment ion channel-related disorders, such as channelopathies, chro

The updated landscape of tumor microenvironment and drug repurposing.

Accumulating evidence shows that cellular and acellular components in tumor microenvironment (TME) can reprogram tumor initiation, growth, invasion, metastasis, and response to therapies. Cancer research and treatment have switched from a cancer-centric model to a TME-centric one, considering the increasing significance of TME in cancer biology. Nonetheless, the clinical efficacy of therapeutic strategies targeting TME, especially the specific cells or pathways of TME, remains unsatisfactory. Classifying the chemopathological characteristics of TME and crosstalk among one another can greatly b

Роль ядерных рецепторов в развитии множественного склероза: обзор.

Множественный склероз (MS) является следствием раннего возбудительного демиэлирования и прогрессивных нейродегенеративных повреждений в центральной нервной системе (КНС). Несмотря на неясный патогенез MS, происходят два основных процесса: ремонт олигодендроцита и липидный метаболизм. Было отмечено, что ядерные рецепторы играют роль линейных датчиков, регуляторов транскрипционных факторов и модуляторов генного выражения. Один из членов этой семьи, ретиноид X-рецептор (RXR), который образует гетеродимерный комплекс с рецептором печени X (LXR), был замешан в патофизиологии MS. Кроме того, было вы

Neuroscience in peripheral cancers: tumors hijacking nerves and neuroimmune crosstalk.

Cancer neuroscience is an emerging field that investigates the intricate relationship between the nervous system and cancer, gaining increasing recognition for its importance. The central nervous system governs the development of the nervous system and directly affects brain tumors, and the peripheral nervous system (PNS) shapes the tumor microenvironment (TME) of peripheral tumors. Both systems are crucial in cancer initiation and progression, with recent studies revealing a more intricate role of the PNS within the TME. Tumors not only invade nerves but also persuade them through remodeling

NLRX1 limits inflammatory neurodegeneration in the anterior visual pathway.

Chronic innate immune activation in the central nervous system (CNS) significantly contributes to neurodegeneration in progressive multiple sclerosis (MS). Using multiple experimental autoimmune encephalomyelitis (EAE) models, we discovered that NLRX1 protects neurons in the anterior visual pathway from inflammatory neurodegeneration. We quantified retinal ganglion cell (RGC) density and optic nerve axonal degeneration, gliosis, and T-cell infiltration in Nlrx1-/- and wild-type (WT) EAE mice and found increased RGC loss and axonal injury in Nlrx1-/- mice compared to WT mice in both active immu
