Иммуномодулирующий и противовоспалительный потенциал S-нитросглутатиона (GSNO) при множественной склерозе: обзор механизмов и терапевтических перспектив.

Многофакторная демиелинизация (МС) — это хроническое аутоиммунное заболевание центральной нервной системы (СНС), характеризующееся длительной нейроинфляминацией, окислительным стрессом, демиелинизацией и прогрессирующей нейродегенерацией. Несмотря на то, что МС остается неизлечимым, современные терапевтические средства (ТМС) помогают снизить частоту обострений и задерживать прогрессирование заболевания. Недавно разработанные инъекционные и инфузийные биологические ТМС обеспечивают целенаправленную иммуномодуляцию, но их клиническая полезность ограничена родственными методами введения и возможн

Tuning epigenetics to enhance cancer virotherapy.

Cancer remains a major global health challenge, driving intensive research into novel therapeutic strategies. Oncolytic viruses (OVs) including herpesviruses, adenoviruses and echoviruses, have emerged as promising agents for cancer treatment, with several achieving regulatory approval. These viruses selectively lyse tumor cells and stimulate antitumor immunity. Nevertheless, their efficacy is constrained by limitations such as neutralization by serum factors and tumor cell resistance. Concurrently, epigenetic inhibitors modulate gene expression to suppress tumor proliferation and reshape immu

Targeting the CD47-TSP1 Axis in Abdominal Aortic Aneurysm: A Novel Immunotherapeutic Approach.

Abdominal aortic aneurysm (AAA) is a life-threatening vascular disorder characterized by progressive dilation and weakening of the abdominal aortic wall. Despite advances in surgical repair, rupture remains associated with mortality rates exceeding 65%, and no effective pharmacological therapy exists to prevent disease progression. Increasing evidence highlights chronic inflammation, extracellular matrix degradation, and immune dysregulation as central drivers of AAA pathogenesis. Among these mechanisms, the thrombospondin-1 (TSP1)-CD47 signaling axis has emerged as a critical upstream regulat

Proteolytic chemokine cleavage as a regulator of lymphocytic infiltration in solid tumors.

In the past decade, immune-based therapies such as monoclonal antibodies against tumor epitopes or immune checkpoint inhibitors have become an integral part of contemporary cancer treatment in many entities. However, a fundamental prerequisite for the success of such therapies is a sufficient trafficking of tumor-infiltrating lymphocytes into the tumor microenvironment. This infiltration is facilitated by chemokines, a group of about 50 small proteins capable of chemotactically guiding leukocytes. Proteolytic inactivation of chemokines leading to an impaired infiltration of immune effector cel

IL-6/IL-12 суперсемейство цитокинов и регламентируемых лимфоцитов играет важнейшую роль в этиологии и борьбе с аутоиммунными заболеваниями CNS.

Цитокины влияют на решения наивных лимфоцитов о клеточной порче и определяют исход иммунной реакции путем подачи сигналов, регулирующих инициирование, интенсивность и продолжительность иммунной реакции. Вместе с тем аномальное регулирование физиологических уровней цитокина способствует развитию аутоиммунных и других подстрекательских заболеваний. Сверхсемейство цитокинов Interleukin 6 (IL-6)/IL-12 оказывает глубокое влияние на все аспекты иммунитета хостинга, и в ходе этого обзора мы уделяем особое внимание сигнальным путям, которые способствуют выполнению их функций, с уделением особого внима

Cancer Resistance to Immunotherapy: Comprehensive Insights with Future Perspectives.

Cancer immunotherapy is a type of treatment that harnesses the power of the immune systems of patients to target cancer cells with better precision compared to traditional chemotherapy. Several lines of treatment have been approved by the US Food and Drug Administration (FDA) and have led to remarkable success in the treatment of solid tumors, such as melanoma and small-cell lung cancer. These immunotherapies include checkpoint inhibitors, cytokines, and vaccines, while the chimeric antigen receptor (CAR) T-cell treatment has shown better responses in hematological malignancies. Despite these

The impact of gut microbial signals on hematopoietic stem cells and the bone marrow microenvironment.

Hematopoietic stem cells (HSCs) undergo self-renewal and differentiation in the bone marrow, which is tightly regulated by cues from the microenvironment. The gut microbiota, a dynamic community residing on the mucosal surface of vertebrates, plays a crucial role in maintaining host health. Recent evidence suggests that the gut microbiota influences HSCs differentiation by modulating the bone marrow microenvironment through microbial products. This paper comprehensively analyzes the impact of the gut microbiota on hematopoiesis and its effect on HSCs fate and differentiation by modifying the b

Sp140L функционирует как фактор ограничения герпесвируса, подавляющий вирусную транскрипцию и активирующий интерферонально-стимулированные гены.

Герпесвирусы, включая вирус Эпштейн-Барр (ЭБВ), - человеческий онкогенный вирус и важнейший пусковой механизм множественного склероза, - должны обходить механизмы ДНК-разведки, чтобы установить пожизненную скрытую инфекцию. Поэтому герпесвирусы кодируют вирусные белки, чтобы разрушить ключевые факторы, связанные с зондированием ДНК и вирусным ограничением. Первый вирусный белок латентности, выраженный EBNA-LP, крайне важен для преобразования наивных клеток B и установления вирусного генного экспрессии, однако его роль в уклонении от защиты хостов остается неясной. Используя одноклеточную после

Cryoglobulinemia: An update on classification, pathophysiology, clinical presentation, and management.

Cryoglobulinemia (CG) is defined by the presence of serum immunoglobulins that precipitate below 37°C and redissolve upon rewarming. It is classified into three types based on immunoglobulin composition. Type I, a rare form, involves monoclonal IgM or IgG and is linked to lymphoproliferative disorders. Types II and III are known as mixed CG (MC): Type II consists of polyclonal IgG and monoclonal IgM with rheumatoid factor (RF) activity, whereas Type III includes polyclonal IgG and polyclonal IgM with RF activity. MC is predominantly associated with hepatitis C virus (HCV) infection and involve

The Role of Chemokines in Obesity and Exercise-Induced Weight Loss.

Obesity is a global health crisis that is closely interrelated to many chronic diseases, such as cardiovascular disease and diabetes. This review provides an in-depth analysis of specific chemokines involved in the development of obesity, including C-C motif chemokine ligand 2 (CCL2), CCL3, CCL5, CCL7, C-X-C motif chemokine ligand 8 (CXCL8), CXCL9, CXCL10, CXCL14, and XCL1 (lymphotactin). These chemokines exacerbate the symptoms of obesity by either promoting the inflammatory response or by influencing metabolic pathways and recruiting immune cells. Additionally, the research highlights the po

Intravenous vitamin C for reduction of cytokines storm in acute respiratory distress syndrome.

The recent outbreak of Covid19 has required urgent treatments for numerous patients. No suitable vaccines or antivirals are available for Covid19. The efficiency against Covid19 of WHO therapies of choice, that are two antivirals developed for other pathologies, is controversial. Therefore, alternative approaches are required. Intravenous (IV) Vitamin C (Vit-C) has emerged as one of the other alternatives for this purpose. Here we review the effects of IV Vit-C on the immune system response, the antiviral properties of IV Vit-C, and finally the antioxidant properties of IV Vit-C to specificall

Природные клетки убийцы в множестве склерозов: враги или друзья?

Множественный склероз (MS) — иммунное расстройство, связанное с центральной нервной системой (CNS), в которой происходит демиэлизация. Считается, что инициирование и прогрессирование MS в значительной степени зависят от CD4+T лимфоцитов, однако новые данные подчеркивают участие врожденной иммунной системы в реакции на болезни MS. В целом некоторые виды иммунных клеток играют определенную роль, при этом существенно важное значение имеют клетки естественного убийцы (НК). В ходе аутоиммунной болезни, как, например, MS, различные подвиды клеток естественного убийцы функционируют по-разному. У люде
