Despite the effective reduction in PASI score and improvement in disease severity, the concentrations of CD41a (7305/μL versus 7198/μL, p > 0.05) and CD31 (10036/μL versus 12075/μL, p > 0.05) positive MPs were not different significantly in patients with psoriasis before and 4 months after UST (Figure 1). The gene discussed is PECAM1; the disease is psoriasis.
