The anti-inflammatory effects of mesenchymal stem cells and their research progress in hematopoietic stem cell transplantation: A comprehensive review.

Hematopoietic stem cell transplantation (HSCT) is frequently accompanied by severe inflammation-related complications, among which graft-versus-host disease (GVHD) stands out as one of the most common and life-threatening. As a systemic inflammatory disorder, GVHD arises when donor T cells recognize the recipient's alloantigens and initiate an immune attack. Currently, effective second-line treatment options remain scarce for patients with antibiotic-resistant or steroid-refractory GVHD. Mesenchymal stem cells (MSCs) are non-hematopoietic cells widely distributed in fetal and adult tissues and

Redox Remodeling by Nutraceuticals for Prevention and Treatment of Acute and Chronic Inflammation.

Antioxidant-rich dietary regimens are considered the best practice to maintain health, control inflammation, and prevent inflammatory diseases. Yet, nutraceuticals as food supplements are self-prescribed and purchasable over the counter by healthy individuals for the purpose of beneficial effects on fitness and aging. Hence, the effectiveness, safety, and correct intake of these compounds need to be better explored. Since redox-modulating activity of these compounds appears to be involved in activation and or suppression of immune cells, the preventive use of nutraceuticals is very attractive

The Gut-Bone Marrow Axis: Deciphering the Mechanistic Impact of Microbial Metabolites on Hematopoietic Homeostasis and Disorders.

The gut microbiota is increasingly recognized as a dynamic endocrine-like microbial network that exerts systemic effects far beyond the gastrointestinal tract. Emerging evidence supports the existence of a "gut-bone marrow axis" through which gut-derived signals orchestrate hematopoietic homeostasis. However, shifting from correlative observations to causal mechanisms remains a major challenge in defining precise microbial impacts on hematopoietic outcomes. In this review, we systematically synthesize current knowledge on the molecular mechanisms by which microbial products-specifically short-

Микроэкология и тренировка: целевое воздействие на ось микробиота-Гут-Брэйна для лечения заболеваний центральной нервной системы.

Кишечная микробиота (ГМ) может играть решающую роль в развитии и развитии заболеваний центральной нервной системы (ЦНС). Микроэкология и упражнение могут влиять на состав и функции ГМ, оказывая тем самым позитивное воздействие на НКЦ. Ожидается, что комбинированные физические упражнения и микроэкология позволят более комплексно и эффективно решать проблемы, связанные с заболеваниями CNS, через ось микробиота-гут-мозгов (MMBA), потенциально превысив результаты отдельных мероприятий. Однако в настоящее время по этой теме не проводится соответствующих обзоров. В этом обзоре мы изучаем взаимосвязь

Тип перегонки 1 диабет через ось эндоканнабиноидома-микробиота: системная биологическая перспектива.

Тип 1 диабет (T1D) давно признан аутоиммунным заболеванием на основе Т. Вместе с тем все больше фактов свидетельствует об участии в его развитии факторов, связанных с метаболизмом, подстрекательством и кишечной микробиотой. Эндоканнабиноидная система (ЭКС), являющаяся одним из ключевых регуляторов иммунного и метаболического гомеостаза, все чаще привлекается к аутоиммунной патофизиологии, в частности благодаря ее взаимодействию с кишечными метаболитами. В этой гипотетической статье подчеркивается необходимость пересмотра патофизиологии Т1D путем интеграции дисфункции ЭКС, кишечного дисбиоза и

Intestinal barrier functions in hematologic and oncologic diseases.

The intestinal barrier is a complex structure that not only regulates the influx of luminal contents into the systemic circulation but is also involved in immune, microbial, and metabolic homeostasis. Evidence implicating disruption in intestinal barrier functions in the development of many systemic diseases, ranging from non-alcoholic steatohepatitis to autism, or systemic complications of intestinal disorders has increased rapidly in recent years, raising the possibility of the intestinal barrier as a potential target for therapeutic intervention to alter the course and mitigate the complica

Pituitary Adenylate Cyclase-Activating Polypeptide: 30 Years in Research Spotlight and 600 Million Years in Service.

Emerging from the depths of evolution, pituitary adenylate cyclase-activating polypeptide (PACAP) and its receptors (i.e., PAC1, VPAC1, VPAC2) are present in multicellular organisms from Tunicates to humans and govern a remarkable number of physiological processes. Consequently, the clinical relevance of PACAP systems spans a multifaceted palette that includes more than 40 disorders. We aimed to present the versatility of PACAP1-38 actions with a focus on three aspects: (1) when PACAP1-38 could be a cause of a malfunction, (2) when PACAP1-38 could be the cure for a malfunction, and (3) when PA

Intestinal Microbes and Hematological Malignancies.

Hematological malignancies are diverse, with high malignancy characteristics, poor prognoses, and high mortality rates. The development of hematological malignancies is driven by genetic factors, tumor microenvironment factors, or metabolic factors; however, even when considering all of these factors, one still cannot fully estimate the risk of hematological malignancies. Several recent studies have demonstrated an intimate connection between intestinal microbes and the progression of hematological malignancies, and gut microbes play a primary role in the initiation and progression of hematolo

Нейтрофилы, НЕТ и множественный склероз: мини-обзор.

Множественный склероз (MS), хроническое аутоиммунное и дегенеративное заболевание, характеризующееся активацией различных провокационных клеток, приводит к обезвоживанию и нейрональным травмам. Нейтрофилы, которые часто недооцениваются в MS, получают все большее внимание за свои важные функции у пациентов MS и экспериментальную аутоиммунную энцефаломиелитную модель (EAE). Нейтрофилы играют многообразную роль в посредничестве патогенеза аутоиммунных заболеваний, и многочисленные исследования свидетельствуют о том, что нейтрофилы могут играть решающую роль благодаря образованию нейтрофильной вне

The Impact of NLRP3 Activation on Hematopoietic Stem Cell Transplantation.

NLR family pyrin domain-containing 3 (NLRP3) is an intracellular protein that after recognizing a broad spectrum of stressors, such as microbial motifs and endogenous danger signals, promotes the activation and release of the pro-inflammatory cytokines IL-1β and IL-18, thus playing an essential role in the innate immune response. Several blood cell types, including macrophages, dendritic cells, and hematopoietic stem and progenitor cells (HSPCs), express NLRP3, where it has been implicated in various physiological and pathological processes. For example, NLRP3 participates in the development a

The 'speck'-tacular oversight of the NLRP3-pyroptosis pathway on gastrointestinal inflammatory diseases and tumorigenesis.

The NLRP3 inflammasome is an intracellular sensor and an essential component of the innate immune system involved in danger recognition. An important hallmark of inflammasome activation is the formation of a single supramolecular punctum, known as a speck, per cell, which is the site where the pro-inflammatory cytokines IL-1β and IL-18 are converted into their bioactive form. Speck also provides the platform for gasdermin D protein activation, whose N-terminus domain perforates the plasma membrane, allowing the release of mature cytokines alongside with a highly inflammatory form of cell death

New Insights and Future Perspectives of APRIL in IgA Nephropathy.

IgA nephropathy (IgAN) is characterized by immune-mediated glomerulonephritis, with the accumulation of galactose-deficient IgA1 (Gd-IgA1) in the glomeruli and increased levels of circulating Gd-IgA1 and Gd-IgA1-containing immune complexes. An incomplete understanding of the underlying mechanisms and differences in clinical and pathological features between individuals and ethnicities has contributed to the lack of established treatments for IgAN. A tumor necrosis factor (TNF) family member, a proliferation-inducing ligand (APRIL), is a crucial cytokine essential for the generation and surviva

Hypercalcemia in Cancer: Causes, Effects, and Treatment Strategies.

Calcium plays central roles in numerous biological processes, thereby, its levels in the blood are under strict control to maintain homeostatic balance and enable the proper functioning of living organisms. The regulatory mechanisms ensuring this balance can be affected by pathologies such as cancer, and as a result, hyper- or hypocalcemia can occur. These states, characterized by elevated or decreased calcium blood levels, respectively, have a significant effect on general homeostasis. This article focuses on a particular form of calcium metabolism disorder, which is hypercalcemia in neoplasm

R-spondin signaling as a pivotal regulator of tissue development and homeostasis.

R-spondins (Rspos) are cysteine-rich secreted glycoproteins which control a variety of cellular functions and are essential for embryonic development and tissue homeostasis. R-spondins (Rspo1 to 4) have high structural similarity and share 60% sequence homology. It has been shown that their cysteine-rich furin-like (FU) domain and the thrombospondin (TSP) type I repeat domain are essential for initiating downstream signaling cascades and therefore for their biological functions. Although numerous studies have unveiled their pivotal role as critical developmental regulators, the most important

Clostridium butyricum alleviates multiple myeloma by remodeling the bone marrow microenvironment and inhibiting PI3K/AKT pathway through the gut‒bone axis.

Emerging evidence reveals a strong connection between the gut microbiota and cancer. However, the exact role of gut microbiota dysbiosis in multiple myeloma (MM) is poorly understood, and the therapeutic potential of microbiota-targeted interventions represents a promising strategy that demands urgent mechanistic and translational investigation. First, we conducted a comprehensive microbiome-metabolite analysis between MM patients and healthy individuals. The result revealed a marked compositional difference characterized by reduced abundances of butyrate-producing bacteria and diminished buty

Gastrointestinal Stromal Tumor Induced Hypercalcemia.

Hypercalcemia in patients with cancer is a common laboratory finding affecting up to 44% of that patient population. 1,25-Dihydroxyvitamin D3 mediated hypercalcemia is one of the rare mechanisms of this endocrine emergency in cancer patients. It is even rarer for solid organ neoplasms to present with hypercalcemia mediated through the production of 1,25-dihydroxyvitamin D3. We report a case of a 77-year-old female who presented to the hospital with hypercalcemia and later was found to have metastatic gastrointestinal stromal tumor. There have been only 5 cases of gastrointestinal stromal tumor

Роль микробиомы в множестве миелом: новые знания и терапевтические возможности.

Множественная миелома — гематологический рак, описываемый распространением плазменных клеток в костном мозге, что вызывает иммунную дисфункцию и другие аномалии. Микробиом кишечника, микробное сообщество в желудочно-кишечном тракте, было обнаружено, что он модифицирует системный иммунитет, воспаление и метаболизм. Хотя взаимосвязь между кишечным микробиомом и множеством миелома была обнаружена в недавних исследованиях, существует пробел в знаниях, связывающий воздействие микробиома на патогенез и лечение множественной миеломы. Несбалансированность в кишечном микробиоме, дисбиозе, может влиять

Gut microbiota shapes cancer immunotherapy responses.

The gut microbiota significantly influences cancer immunotherapy efficacy by modulating immune responses, remodeling the tumor microenvironment (TME), and producing key metabolites. Strategies such as FMT, probiotics, and dietary interventions show promise in enhancing responses to ICIs and ACTs while reducing immune-related adverse events (irAEs). This review summarizes clinical and preclinical findings and discusses microbiota-based interventions and future directions for precision immunotherapy.

The Health-Promoting Effects and the Mechanism of Intermittent Fasting.

Intermittent fasting (IF) is an eating pattern in which individuals go extended periods with little or no energy intake after consuming regular food in intervening periods. IF has several health-promoting effects. It can effectively reduce weight, fasting insulin levels, and blood glucose levels. It can also increase the antitumor activity of medicines and cause improvement in the case of neurological diseases, such as memory deficit, to achieve enhanced metabolic function and prolonged longevity. Additionally, IF activates several biological pathways to induce autophagy, encourages cell renew
