Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dendritic cells (DC) paly a key role in the induction and chronicity of psoriasis by capturing the antigenes and activating the T cell repsonse. This activation requires their migration from the cutaneous sensitisation site to the lymph nodes. This migration requires an important intracellular metabolic activity, with a strong involvmenet of glucdic metabolism. This activity is linked with the systemic activity. This study aims to compare the migration and the phenotypic and metabolic caracteristics of blood and skin DCs in patients with or without psoriasis and with or without type 2 diabetes,

Study Groups

Production of IL-23 of blood and skin dendriti cells (CD)

Simultaneously evaluate the migratory capacity and production of IL-23 of blood and skin cDC on peripheral venous blood and skin biopsies of psoriatic patients with and without type 2 diabetes and control patients (with or without type II diabetes) depending on their metabolic status.

Group Type OTHER

Biopsy and venous blood

Intervention Type OTHER

A skin biopsy will be performed under local anesthesia in diabetic and non-diabetic psoriatic patients (25 per group) in the injured area (joint extension) and in the non-injured area more than 2 cm from any lesion in the same area. In patients in the diabetic or non-diabetic control group (25 per group) only one biopsy will be performed.

Peripheral venous blood will be collected in heparin tubes for metabolic parameter analysis and blood CD analysis
