Study of the µ opioid receptor in cutaneous ulcers of leishmaniasis and sporotrichosis according to the complaints of local pain

Patients with cutaneous leishmaniasis or sporotrichosis with ulcerated lesions may present similar epidemiological and clinical characteristics. Local pain is often referred to in the sporotrichosis lesions, but not in cutaneous leishmaniasis. The µ Opioid Receptor (MOR) is indirectly associated to the production of cytokines, and is related to the epidermal proliferation.
