Table III. MBP-primed T cells induce the production of NO in mouse primary microglia.

Mouse primary microglia received MBP-primed T cells at different ratios under serum-free conditions. After 24 h of incubation, concentrations of nitrite were measured in the supernatants as described under “Materials and Methods.” Data are mean ± S.D. of three different experiments.
