Brief summary: Psoriatic arthritis (PsA) is a chronic musculoskeletal disease that affects 0.1%-1% of the general population and about 20% of patients with psoriasis. Patients with PsA have a multifaceted pain experience, which depends on various factors, including joint inflammation, as well as peripheral and central pain sensitization. Although chronic pain is the most common symptom of PsA, few is known about the mechanisms driving it. From this point of view, the interactions between immune cells and nociceptors in the context of inflammation-related pain are emerging as a hot topic. Many studies suggested that IL-23/IL-17 pathway may play a pivotal role in this regard. This is consistent with data currently available regarding Guselkumab in PsA. Indeed, according to DISCOVER 1 and DISCOVER 2, two randomized phase III trials, patients receiving Guselkumab achieved, among others, minimal disease activity state, significant improvement in the SF-36 physical component score, and visual analog scale of pain. This study proposal aims to evaluate the potential role of Guselkumab in modulating pain perception in PsA patients from a molecular, cellular, and electrophysiological point of view.
