Abstract The interplay between the commensal microbiota and mammalian immune system development function includes multifold interactions in homeostasis disease. microbiome plays critical roles training of major components host’s innate adaptive system, while orchestrates maintenance key features host-microbe symbiosis. In a genetically susceptible host, imbalances microbiota-immunity under defined environmental contexts are believed to contribute pathogenesis multitude immune-mediated disorders. Here, we review microbiome-immunity crosstalk their health disease, providing examples molecular mechanisms orchestrating these intestine extra-intestinal organs. We highlight aspects current knowledge, challenges limitations achieving causal understanding host immune-microbiome interactions, as well impact on diseases, discuss how insights may translate towards future microbiome-targeted therapeutic interventions.

High-Fat, Western-Style Diet, Systemic Inflammation, and Gut Microbiota: A Narrative Review

Cells, Год журнала: 2021, Номер 10(11), С. 3164 - 3164

Опубликована: Ноя. 14, 2021

The gut microbiota is responsible for recovering energy from food, providing hosts with vitamins, and a barrier function against exogenous pathogens. In addition, it involved in maintaining the integrity of intestinal epithelial barrier, crucial functional maturation immune system. Western diet (WD)—an unhealthy high consumption fats—can be broadly characterized by overeating, frequent snacking, prolonged postprandial state. term WD commonly known intuitively understood. However, strict digital expression nutrient ratios not precisely defined. Based on US data 1908–1989, calory intake available fats increased 32% to 45%. Besides metabolic aspects (hyperinsulinemia, insulin resistance, dyslipidemia, sympathetic nervous system renin-angiotensin overstimulation, oxidative stress), consequences excessive fat (high-fat diet—HFD) comprise dysbiosis, dysfunction, permeability, leakage toxic bacterial metabolites into circulation. These can strongly contribute development low-grade systemic inflammation. This narrative review highlights most important recent advances linking HFD-driven dysbiosis HFD-related inflammation, presents pathomechanisms these phenomena, examines possible causative relationship between pro-inflammatory status changes.

Nutritional Components in Western Diet Versus Mediterranean Diet at the Gut Microbiota–Immune System Interplay. Implications for Health and Disease

Nutrients, Год журнала: 2021, Номер 13(2), С. 699 - 699

Опубликована: Фев. 22, 2021

The most prevalent diseases of our time, non-communicable (NCDs) (including obesity, type 2 diabetes, cardiovascular and some types cancer) are rising worldwide. All them share the condition an “inflammatory disorder”, with impaired immune functions frequently caused or accompanied by alterations in gut microbiota. These multifactorial maladies also have common malnutrition related to physiopathology. In this context, diet is greatest modulator system–microbiota crosstalk, much interest, new challenges, arising area precision nutrition as a way towards treatment prevention. It fact that westernized (WD) partly responsible for increased prevalence NCDs, negatively affecting both microbiota system. Conversely, other nutritional approaches, such Mediterranean (MD), positively influence system microbiota, proposed not only potential tool clinical management different disease conditions, but prevention health promotion globally. Thus, purpose review determine regulatory role components WD MD interplay, order understand, create awareness of, over key components.

Metastasis-Initiating Cells and Ecosystems

Cancer Discovery, Год журнала: 2021, Номер 11(4), С. 971 - 994

Опубликована: Апрель 1, 2021

Abstract Metastasis is initiated and sustained through therapy by cancer cells with stem-like immune-evasive properties, termed metastasis-initiating (MIC). Recent progress suggests that MICs result from the adoption of a normal regenerative progenitor phenotype malignant cells, intrinsic programs to survive stresses metastatic process, undergo epithelial–mesenchymal transitions, enter slow-cycling states for dormancy, evade immune surveillance, establish supportive interactions organ-specific niches, co-opt systemic factors growth recurrence after therapy. Mechanistic understanding molecular mediators MIC phenotypes host tissue ecosystems could yield therapeutics improve patient outcomes. Significance: Understanding origins, traits, vulnerabilities capacity initiate metastasis in distant organs, microenvironments support ability these surveillance regenerate tumor, critical developing strategies prevention treatment advanced cancer. Leveraging recent our here we review nature their offer perspective on how this knowledge informing innovative treatments cancers.
