Therapeutic Potential of Microbiota Modulation in Psoriasis: Current Evidence and Future Directions

The human microbiota plays a significant role in health and the development of autoimmune diseases by maintaining gut-skin homeostasis through diverse microbial communities. Dysbiosis, or imbalance in these communities, is increasingly recognized as a contributing factor in the pathogenesis of autoimmune and inflammatory diseases, including psoriasis. Psoriasis is characterized by immune dysregulation, leading to red and scaly plaques that significantly reduce patients' quality of life. Current evidence highlights the gut microbiota's critical role in driving immune responses and chronic inflammation associated with psoriasis. Therapeutic strategies aimed at restoring microbial balance, such as probiotics, have demonstrated promise in reducing disease severity. Additionally, fecal microbiota transplantation (FMT) has emerged as a novel intervention, with early studies suggesting its potential to alleviate symptoms by correcting gut dysbiosis. These approaches underscore the importance of microbiota-targeted therapies in addressing the systemic nature of psoriasis and pave the way for advancements in personalized treatment strategies.
