Fig. 1. VEGF concentrations in serum from HIV-1-infected individuals with or without KS. VEGF was measured in duplicate 100 µl samples of serum by ELISA. Values are the means of duplicate samples. VEGF concentrations were significantly higher in persons with KS than in persons without KS (P = 0.02, Mann-Whitney test). Serum levels of IL-12 (15 pg/ml) were not different in individuals with or without KS.
