Treatment Main mechanisms of action Vascular impact References
Anti-TNF-α (infliximab, etanercept and adalimumab) Bind soluble TNF-α (immunosuppressant) Inhibit TNF-α induced angiogenesis and the expression of adhesion molecules [36,49,50,53]
Anti-CD11a (efalizumab) Block LFA-1 (inhibition of T cell activation by dendritic cells) Block leukocyte adherence to endothelium via ICAM-1 [1,56]
Retinoids (acitretin) Retinoic acid receptors agonist (antiproliferative and promotion of epidermal differentiation) Downregulate VEGF secretion by keratinocytes [22,47,58]
Vitamin D3 analogues (calcitriol, calcipotriol and tacalcitol) Vitamin D receptor agonist (antiproliferative and promotion of epidermal differentiation) Inhibit VEGF-induced angiogenesis and has antiproliferative activity on endothelial cells [59-61]
Methotrexate Dihydrofolate reductase inhibitor (antiproliferative and immunosuppressant) Inhibit the expression of adhesion molecules and has antiproliferative activity on endothelial cells [50,62-66]
Cyclosporine Inhibit calcineurin causing a downregulation of IL-2 (immunosuppressant) Inhibit VEGF-induced angiogenesis [67,68]
Phototherapy (PUVA, nUVB) Damage DNA (antiproliferative and lymphotoxic) Downregulate VEGF secretion and has antiproliferative activity on endothelial cells [47,69,70]
