Expression of MMP-1 and MMP-3 in B. burgdorferi (Bb)-infected human primary chondrocytes. Primary HC cultures were either uninfected or infected with B. burgdorferi (107 organisms) for various lengths of time. Expression of MMP-1 (A) and MMP-3 (B) was measured by ELISA. The experiment was repeated twice in duplicate and a representative experiment is shown. Error bars represent standard deviations.
