Figure 3 represents the surface expression of CD40 in classical monocytes in a single HC and MS patient. Maximal surface expression of CD40 was higher in MS patients (2 × 104) than in the HC subjects (8 × 103) (Figure 3). No significant difference was found for intermediate CD14++CD16+ monocytes between the groups examined. The gene discussed is CD14; the disease is myeloid sarcoma.
