Psoriasis is a chronically relapsing inflammatory skin disorder affecting about 2% of the worldwide population. The disease is associated with important systemic manifestations, including cardiovascular comorbidities and metabolic syndrome. In addition, about 30% of patients develop joint inflammation known as psoriatic arthritis (PsA). Our knowledge on the pathogenesis of psoriasis has dramatically expanded in the last decade, suggesting the existence (or co-existence) of both auto-immune and auto-inflammatory components. Skin lesions develop from a complex interplay between keratinocytes, vascular endothelium, dendritic cells, and T cells, generating a self-sustaining inflammatory cycle. Within this cycle, epidermal CD8+ T lymphocytes specific for self-antigens may represent the major autoimmune mechanism. Despite the recent progress in the comprehension of the pathogenesis of psoriasis many questions remain open, ranging from the plaque-initiating events to the characterization of the autoimmune /autoinflammatory components of the disease. The mechanisms that link cutaneous psoriasis to its extra-cutaneous and systemic manifestations also remain vague. In this Research Topic we invited top scientists to summarize the front-line research in the field of immunology of cutaneous psoriasis and its systemic and joint manifestations. Our intention was to integrate the pillar concepts of psoriasis immunopathology with the most novel insights, aiming at providing an advanced view of this rapidly evolving and fascinating field.
