Mechanical stretch-induced ATP release from keratinocytes triggers Koebner phenomenon in psoriasis

      The Koebner phenomenon (KP) is defined as de novo development of isomorphic cutaneous lesions by external trauma, such as scratch, pressure, and stretch, in the uninvolved skin of patients with cutaneous diseases such as psoriasis. However, the mechanisms behind KP are not yet fully understood.
