Innovative Therapeutic Strategies for Asthma: The Role of Gut Microbiome in Airway Immunity

There is a growing acknowledgment of the gut microbiome's impact on widespread immune responses, which holds considerable importance for comprehending and addressing asthma. Recent research has clarified the complex interactions between gut microbiota and airway immune systems, demonstrating that microbial diversity and composition can affect both the initiation and advancement of asthma. Gut microbial species and metabolites primarily short-chain fatty acids (SCFAs) may either worsen or reduce airway inflammation by regulating the balance of helper T cell 1 (Th1) / helper T cell 2 (Th2) and other immune mediators. This interaction presents innovative therapeutic possibilities, including modulation of gut microbiome during early life through breastfeeding and control of antibiotic use, particularly with prebiotics, which could selectively stimulate the growth of beneficial bacteria, promote immune maturation, reducing susceptibility to asthma and allergic airway inflammation. Besides, investigating the gut-lung axis reveals new opportunities for personalized medicine in asthma treatment, emphasizing the necessity for integrated strategies that take individual microbiome profiles into account. This paper examines the latest developments in comprehending the mechanisms by which gut microbiota affect airway inflammation and hypersensitivity, especially focusing on treatment strategies.
