Удельное микробное соотношение в кишечном микробиоме связано с множественным склерозом.

Гут микробиота дисбиоз связан с множественным склерозом (MS), однако причинно-следственная связь между конкретными кишечными бактериями и патогенезом MS остается слабой. Поэтому мы описали микробиом стула людей с MS (PwMS) и здоровым управлением (HC) с использованием метагеномической последовательности дробовика. PwMS продемонстрировал отличный микробиом по сравнению с HC, при этом виды Crevotella copri (PC) и Blautia были движущими силами микробных сообществ в HC и PwMS, соответственно. В результате применения к мышам видов MS-ding Blautia (Blautia Wexlerae; BW) повысились уровни кишечных мар

Gut microbiota dysbiosis is associated with multiple sclerosis (MS), but the causal relationship between specific gut bacteria and MS pathogenesis remains poorly understood. Therefore, we profiled the stool microbiome of people with MS (PwMS) and healthy controls (HC) using shotgun metagenomic sequencing. PwMS showed a distinct microbiome compared to HC, wit…

What Are the Peripheral Blood Determinants for Increased Osteoclast Formation in the Various Inflammatory Diseases Associated With Bone Loss?

Local priming of osteoclast precursors (OCp) has long been considered the main and obvious pathway that takes place in the human body, where local bone lining cells and RANKL-expressing osteocytes may facilitate the differentiation of OCp. However, priming of OCp away from bone, such as in inflammatory tissues, as revealed in peripheral blood, may represent a second pathway, particularly relevant in individuals who suffer from systemic bone loss such as prevalent in inflammatory diseases. In this review, we used a systematic approach to review the literature on osteoclast formation in peripher

NF-κB: master regulator of cellular responses in health and disease.

The NF-κB transcription control proteins play widespread roles in cellular behavior, regulating immune responses, inflammation, cell survival, proliferation, and development. Here, we attempt to comprehensively review these diverse functions and underlying mechanisms, leading readers to relevant references of both historic and topical importance. Because of the huge number of NF-κB control mechanisms and functions, and the vast literature that describes these, being comprehensive is a daunting task but we hope that readers will find clues to lead them to whatever understanding they may seek.

Immunosuppression in Glomerular Diseases: Implications for SARS-CoV-2 Vaccines and COVID-19.

BackgroundGlomerular diseases (GD) are chronic conditions that often involve immune dysfunction and require immunosuppressive therapy (IST) to control underlying pathogenesis. Unfortunately, such diseases appear to heighten risks of severe outcomes in COVID-19 and predispose to other infections that may be life-threatening. Thus, averting preventable infections is imperative in GD patients.SummaryThe advent of vaccines demonstrated to be safe and efficacious against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has favorably impacted the COVID-19 pandemic epidemiology.

Mechanisms of spinal glial activation in chemotherapy-induced peripheral neuropathy: Focus on microglia and astrocytes.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common complication in patients with malignant tumors during chemotherapy. The pathological mechanisms of CIPN remain unclear, and effective preventive and therapeutic strategies are still lacking, posing a major challenge in clinical practice. Aberrant activation of spinal glial cells, particularly microglia and astrocytes, is a key pathological hallmark of CIPN. Evidence from multiple animal models supports a causal link between glial activation and CIPN, suggesting that glial cells may serve as potential therapeutic targets. However, ow

Chemotherapy-Induced Tissue Injury: An Insight into the Role of Extracellular Vesicles-Mediated Oxidative Stress Responses.

The short- and long-term side effects of chemotherapy limit the maximum therapeutic dose and impair quality of life of survivors. Injury to normal tissues, especially chemotherapy-induced cardiomyopathy, is an unintended outcome that presents devastating health impacts. Approximately half of the drugs approved by the Food and Drug Administration for cancer treatment are associated with the generation of reactive oxygen species, and Doxorubicin (Dox) is one of them. Dox undergoes redox cycling by involving its quinone structure in the production of superoxide free radicals, which are thought to
