New Insights into the Relationship between Gut Microbiota and Radiotherapy for Cancer.

Cancer is the second most common cause of death among humans in the world, and the threat that it presents to human health is becoming more and more serious. The mechanisms of cancer development have not yet been fully elucidated, and new therapies are changing with each passing day. Evidence from the literature has validated the finding that the composition and modification of gut microbiota play an important role in the development of many different types of cancer. The results also demonstrate that there is a bidirectional interaction between the gut microbiota and radiotherapy treatments f

Gut-Bone Axis: A Non-Negligible Contributor to Periodontitis.

Periodontitis is a polymicrobial infectious disease characterized by alveolar bone loss. Systemic diseases or local infections, such as diabetes, postmenopausal osteoporosis, obesity, and inflammatory bowel disease, promote the development and progression of periodontitis. Accumulating evidences have revealed the pivotal effects of gut microbiota on bone health via gut-alveolar-bone axis. Gut pathogens or metabolites may translocate to distant alveolar bone via circulation and regulate bone homeostasis. In addition, gut pathogens can induce aberrant gut immune responses and subsequent homing o

Mycobiota и Antifungal Antibodies как новые целевые показатели для диагностики и прогнозирования болезней человека.

Человеческое тело колонизируется различными микроорганизмами, при этом наиболее активно изучаются бактерии. Однако грибы, которые в совокупности известны как «микобиота», все чаще признаются в качестве составных компонентов микробиоты, населяющей почти все мукосальные поверхности. Комменсальные грибы оказывают влияние на иммунитет хост-приемника, как и бактерии, и способствуют выполнению других важных функций, включая метаболизм. В этом новом понимании грибы рассматриваются как потенциальные биомаркеры для диагностики и прогнозирования различных заболеваний. В этом обзоре мы изучаем двойную ро

Can medicinal mushrooms have prophylactic or therapeutic effect against COVID-19 and its pneumonic superinfection and complicating inflammation?

Medicinal mushrooms have documented effects against different diseases, including infections and inflammatory disorders. The related Basidiomycota Agaricus blazei Murill (AbM), Hericium erinaceus (HE), and Grifola frondosa (GF) have been shown to exert antimicrobial activity against viral agents, Gram-positive and Gram-negative bacteria, and parasites in vitro and in vivo. Since the mechanism is immunomodulatory and not antibiotical, the mushrooms should be active against multi-drug resistant microbes as well. Moreover, since these Basidiomycota also have anti-inflammatory properties, they may

Pathophysiology, evaluation, and management of malnutrition in hematologic malignancies: a comprehensive review.

Hematologic malignancies are frequently complicated by malnutrition, a condition that remains underrecognized yet strongly associated with impaired treatment tolerance, immune recovery, and survival. Unlike solid tumors, hematologic malignancies are characterized by diffuse marrow and immune system involvement, rendering host metabolism highly vulnerable to tumor-driven inflammation and therapy-induced immune stress. Accumulating evidence indicates that nutritional deterioration in hematologic malignancies reflects a state of integrated immunometabolic vulnerability-driven by hyperinflammation

Терапевтическая ориентация на нейроинфламацию, вызванную ожирением, и нейродегенерацию.

Ожирение является одним из основных из изменяемых факторов риска, ведущих к нейроинфламмации и нейродегенерации. Чрезмерное содержание жира в ожирении способствует постепенному проникновению иммунных клеток в жировые ткани, что приводит к высвобождению провоспалительных факторов, таких, как цитокины и адипокины. Эти подстрекательские посредники циркулируют по кровотоку, пропагандируя воспаление как на периферии, так и в центральной нервной системе. Гут дисбиоз, который приводит к утечке кишечного барьера, усугубляет воспаление и играет важную роль в увязке ожирения с патогенезом нейроинфламмац
