Lps-induced pde4 expression
WebPDE4 inhibitor rolipram was found to enhance the expression of MKP-1, and MKP-1 mediated, at least partly, the anti-inflammatory effects of PDE4 inhibition. The results suggest that compounds that enhance MKP-1 expression and/or MKP-1 activity hold potential as novel anti-inflammatory drugs. Abbreviations 8-Br-cAMP Web24 apr. 2015 · The PDE4-inhibitors were given at indicated time points and 24h after LPS inhalation, migration of PMNs into the alveolar space (BAL) was evaluated. Data are presented as mean ± SD; n = 6; *P < 0.05 vs. control without LPS; # P < 0.05 vs. control with LPS; °P < 0.05 vs. 3 and 6h after LPS.
