SLE sera stimulate an increase in the number of IL10 SFC. Twenty serum samples from patients with SLE and 18 sera from healthy controls (10% of final volume) were added to 100 µl PBMC suspensions from a healthy donor (5x10⁵ cells/ml) in duplicate. After 20 hours of incubation, the number of IL10 producing cells was enumerated by the ELISPOT technique. The results are representative of two experiment using the same sera and cell donor, with comparable results. Horizontal bars show the median values for each group.
