ECM molecule protein levels as detected by ELISA in VIP-treated B6, PBS-treated B6, and PBS-treated BALB/c corneas under normal conditions and at 1 and 5 days after infection. ITG-α1 (A), CD44 (B), LAMA-1 (C), ECM1 (D), and VCAN (E) protein levels were significantly elevated in VIP-treated corneas over time when compared to PBS-treated B6 mice. In addition, VIP treatment showed similar trends to protein levels normally detected in PBS-treated BALB/c corneas after infection. SPP1 (F), in contrast, was significantly decreased (similar to PBS-treated BALB/c) after VIP treatment when compared to PBS B6 controls.
