The human gut microbiota is a complex ecosystem playing a crucial role in maintaining host health. Recent research highlights its involvement in various physiological processes, including metabolism, immunity, and brain function. Dysbiosis, an imbalance in this microbial community, is increasingly linked to numerous diseases, from inflammatory bowel disease to neurodegenerative disorders, emphasizing the potential for microbiota modulation as a therapeutic strategy [1].
The gut microbiome significantly influences the efficacy and toxicity of cancer immunotherapies. Commensal bacteria can modulate host immune responses, impacting tumor progression and the success of treatments like immune checkpoint inhibitors. Understanding these intricate interactions opens avenues for microbiome-targeted interventions to improve patient outcomes in oncology [2].
Dietary habits profoundly shape the composition and function of the gut microbiota, which in turn influences host metabolism. Recent findings reveal how specific dietary components, such as fibers and fermented foods, can modulate microbial communities, affecting nutrient absorption, energy balance, and the production of beneficial metabolites. This understanding underscores the therapeutic potential of dietary interventions for metabolic health [3].
The gut-brain axis is a bidirectional communication system, heavily influenced by the gut microbiome, with significant implications for neurodevelopment and neurodegenerative diseases. Emerging evidence suggests that microbial metabolites, immune activation, and neural pathways mediate this complex interaction, affecting brain function, behavior, and the pathogenesis of conditions like Parkinson's and Alzheimer's diseases [4].
The skin microbiome, a diverse community of microorganisms residing on the skin surface, plays a pivotal role in maintaining skin homeostasis and influencing the development of dermatological conditions. Recent studies have unveiled its involvement in barrier function, immune modulation, and disease susceptibility, highlighting its therapeutic potential in managing conditions like eczema, acne, and psoriasis [5].
The oral microbiome, a distinct microbial ecosystem, is increasingly recognized for its influence on systemic health beyond the oral cavity. Dysbiosis in the oral microbiome can contribute to inflammatory conditions, impacting the gut microbiome and potentially exacerbating or initiating systemic diseases such as cardiovascular disease, diabetes, and certain cancers through shared inflammatory pathways [6].
The human gut microbiome serves as a major reservoir for antibiotic resistance genes, posing a significant public health threat. Antibiotic exposure can disrupt the delicate balance of the gut microbiota, promoting the selection and spread of resistant bacteria, which can then transfer these resistance genes to pathogens, complicating the treatment of bacterial infections [7].
Short-chain fatty acids (SCFAs), primarily acetate, propionate, and butyrate, are key metabolites produced by the gut microbiota through the fermentation of dietary fibers. These SCFAs are crucial for host health, influencing energy metabolism, gut barrier integrity, and immune responses. Dysregulation in SCFA production is linked to various metabolic and inflammatory disorders, highlighting their therapeutic potential [8].
The maternal microbiome, encompassing microbial communities from the gut, vagina, and oral cavity, plays a critical role in maternal health during pregnancy and in shaping the developing infant's microbiome and immune system. Perturbations in the maternal microbiome are associated with adverse pregnancy outcomes and an increased risk of chronic diseases in offspring, emphasizing the importance of a healthy maternal microbial environment [9].
Precision microbiome engineering, utilizing synthetic biology tools, offers unprecedented opportunities to rationally design and manipulate microbial communities for therapeutic applications. This field aims to create targeted interventions, from engineered probiotics to personalized microbial consortia, to restore microbial balance and treat diseases with greater efficacy and specificity [10].

The human gut microbiota forms a crucial, intricate ecosystem fundamental to host health, impacting metabolic processes, immune responses, and brain function. Dysbiosis, an imbalance in this microbial community, has clear associations with a spectrum of diseases, ranging from inflammatory bowel disease to various neurodegenerative disorders, emphasizing the potential for therapeutic modulation. Beyond the gut, other specialized microbial communities, such as those found on the skin and within the oral cavity, also exert significant influence on both localized and systemic health. The skin microbiome is integral to maintaining skin homeostasis and influences dermatological conditions like eczema, acne, and psoriasis. Similarly, imbalances in the oral microbiome can contribute to inflammatory states, potentially impacting the gut and exacerbating conditions like cardiovascular disease and diabetes. Dietary patterns are powerful modulators of gut microbiota composition and function. Specific components, particularly fibers, drive the production of beneficial metabolites like short-chain fatty acids (SCFAs), which are vital for energy metabolism, gut barrier integrity, and robust immune responses. Furthermore, the maternal microbiome, encompassing multiple body sites, plays a pivotal role in maternal health during pregnancy and critically shapes the developing infant's microbiome and immune system, with implications for offspring health. The gut microbiome's influence extends to critical areas like oncology, where it significantly impacts the efficacy and toxicity of cancer immunotherapies. It also underpins the gut-brain axis, a bidirectional communication system with profound implications for neurodevelopment and the progression of conditions like Parkinson's and Alzheimer's. A pressing public health issue involves the gut microbiome acting as a significant reservoir for antibiotic resistance genes, complicating bacterial infection treatments. To address these complex interactions and dysbiosis-related diseases, precision microbiome engineering is emerging. This field leverages synthetic biology tools to rationally design and manipulate microbial communities, aiming to create highly targeted interventions like engineered probiotics or personalized microbial consortia to restore microbial balance and treat diseases with greater specificity and effectiveness.
