Challenges in Immunomodulation for Psoriasis: Recent Advancements and Need of Therapies

Psoriasis is a chronic immune-mediated skin disorder affecting millions worldwide. The pathogenesis of psoriasis involves dysregulated immune responses characterized by aberrant activation of T cells and proinflammatory cytokines. Immunomodulation has emerged as a promising therapeutic approach for managing psoriasis, aiming to restore immune homeostasis. However, despite significant advancements, challenges persist in developing effective immunomodulatory therapies. This abstract reviews recent developments in psoriasis immunomodulation, encompassing novel targets and therapeutic modalities. Advances in biologics targeting interleukins (IL) and their receptors, such as IL-17, IL-23, and IL-12/23, have demonstrated substantial clinical efficacy. Additionally, small molecules that inhibit Janus kinases (JAK) and phosphodiesterase 4 (PDE4) have shown promise in regulating immune responses. Despite these advancements, certain limitations hinder the success of immunomodulatory therapies. Treatment resistance, safety concerns, and high costs remain critical challenges. Furthermore, a deeper understanding of the complex immunopathogenesis of psoriasis is essential for developing targeted and personalized therapies. In conclusion, immunomodulation has revolutionized the management of psoriasis, offering remarkable improvements in patient outcomes. Continued research and innovative therapeutic strategies are needed to overcome current challenges and pave the way for more efficient, safe, and accessible treatments for psoriasis.
