Ось Гут-Брэйна в нейродегенерации: механистические связи между дисбиозом и нейроатологией.

& ЦЕЛЬ: Ось кишечника по сути представляет собой two- система связи, которая физически соединяет мозг с кишечным трактом. Связь поддерживается через ряд путей, включая нейронные, эндокринные и иммунные пути. Гут дисбиоз, который объясняется как дисбаланс в микробном сообществе, связан с причинно-следственной связью различных нейродегенеративных расстройств, таких, как болезнь Альцгеймера, болезнь Паркинсона и множественный склероз. Однако патологические механизмы в мозге известны лишь частично. В настоящем обзоре описывается процесс кишечного дисбиоза и нейродегенерации с подробным описанием ф

Mucosal-Associated Invariant T Cells in Health and Disease.

Mucosal-associated invariant T (MAIT) cells are a population of evolutionarily conserved, unconventional innate-like T lymphocytes that are restricted by major histocompatibility complex Class I-related (MR1) molecules. They can be activated either in a T-cell receptor-MR1- or cytokine-dependent manner. Activated MAIT cells play crucial roles in maintaining homeostasis and the fine regulation of the immune system. This review presents a systematic exploration of the development, biological characteristics, and multiple effects of MAIT cells in health and various diseases. In healthy individual

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

Mucositis and Infection in Hematology Patients.

Survival in patients with hematological malignancies has improved over the years, both due to major developments in anticancer treatment, as well as in supportive care. Nevertheless, important and debilitating complications of intensive treatment regimens still frequently occur, including mucositis, fever and bloodstream infections. Exploring potential interacting mechanisms and directed therapies to counteract mucosal barrier injury is of the utmost importance if we are to continue to improve care for this increasingly growing patient population. In this perspective, I highlight recent advanc

Pharmacomicrobiomics in Anticancer Therapies: Why the Gut Microbiota Should Be Pointed Out.

Anticancer treatments have shown a variable therapeutic outcome that may be partly attributable to the activity of the gut microbiota on the pathology and/or therapies. In recent years, microbiota-drug interactions have been extensively investigated, but most of the underlying molecular mechanisms still remain unclear. In this review, we discuss the relationship between the gut microbiota and some of the most commonly used drugs in oncological diseases. Different strategies for manipulating the gut microbiota layout (i.e., prebiotics, probiotics, antibiotics, and fecal microbiota transplantati

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

Understanding and Managing Sepsis in Patients With Cancer in the Era of Antimicrobial Resistance.

Sepsis is a frequent complication in immunosuppressed cancer patients and hematopoietic stem cell transplant recipients that is associated with high morbidity and mortality rates. The worldwide emergence of antimicrobial resistance is of special concern in this population because any delay in starting adequate empirical antibiotic therapy can lead to poor outcomes. In this review, we aim to address: (1) the mechanisms involved in the development of sepsis and septic shock in these patients; (2) the risk factors associated with a worse prognosis; (3) the impact of adequate initial empirical ant

Prophylaxis, diagnosis and therapy of infections in patients undergoing high-dose chemotherapy and autologous haematopoietic stem cell transplantation. 2020 update of the recommendations of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO).

To ensure the safety of high-dose chemotherapy and autologous stem cell transplantation (HDC/ASCT), evidence-based recommendations on infectious complications after HDC/ASCT are given. This guideline not only focuses on patients with haematological malignancies but also addresses the specifics of HDC/ASCT patients with solid tumours or autoimmune disorders. In addition to HBV and HCV, HEV screening is nowadays mandatory prior to ASCT. For patients with HBs antigen and/or anti-HBc antibody positivity, HBV nucleic acid testing is strongly recommended for 6 months after HDC/ASCT or for the durati

Clinical innovations and future directions of nanoparticles in the treatment of psychiatric and neurological disorders.

Nanoparticles (NPs) provide a versatile toolkit for psychiatry and neurology by leveraging tunable size, surface chemistry, and payload control to overcome long-standing barriers in central nervous system (CNS) therapy. Lipid, polymeric, inorganic, and hybrid NPs can be engineered to traverse the blood-brain barrier (BBB) via receptor/transporter pathways, target specific cell types, and deliver sustained or stimuli-responsive release. Beyond drug delivery, NPs improve imaging, enable gene/RNA therapeutics, and support anti-inflammatory and neuroprotective strategies, advancing precision medic

Unraveling the Anti-Cancer Mechanisms of Antibiotics: Current Insights, Controversies, and Future Perspectives.

Cancer persists as a significant global health challenge, claiming millions of lives annually despite remarkable strides in therapeutic innovation. Challenges such as drug resistance, toxicity, and suboptimal efficacy underscore the need for novel treatment paradigms. In this context, the repurposing of antibiotics as anti-cancer agents has emerged as an attractive prospect for investigation. Diverse classes of antibiotics have exhibited promising anti-cancer properties in both in vitro and in vivo studies.

Exploring the gut microbiome's influence on cancer-associated anemia: Mechanisms, clinical challenges, and innovative therapies.

BackgroundAnemia is a prevalent and challenging complication in patients with hematologic and solid malignancies, which stems from the direct effects of malignancy, treatment-induced toxicities, and systemic inflammation. It affects patients' survival, functional status, and quality of life profoundly. Recent literature has highlighted the emerging role of the gut microbiome in the pathogenesis of cancer-associated anemia. The gut microbiota, through its intricate interplay with iron metabolism, inflammatory pathways, and immune modulation, may either exacerbate or ameliorate anemia depending
