Recombinant TIMP-1 induces IL-10 expression by a mechanism independent of inhibition of matrix metalloproteinases.
TIMP-1− JD38 cells were incubated in serum-free media with native recombinant TIMP-1 (A) and reduced and alkylated TIMP-1 (B) (destroys enzyme inhibitory but not growth factor activity) and secreted IL-10 measured by ELISA.
