The authors compared the functional activation state and cytokine secretion profile of CD8+ T cells in patients with relapsing-remitting and secondary progressive (SP) MS to those in normal controls.

In addition, they examined cytokine secretion in relationship to single nucleotide polymorphism (SNP) analysis of cytokine genes.

A significant increase in lymphotoxin secretion from anti-CD3-stimulated CD8+ T cells was observed in patients with SPMS as compared to normal controls.

The authors found no significant differences in SNP frequency or in secretion of other cytokines.
