In this study, we investigated the association between phosphodiesterase (PDE), specifically PDE1, and asthma using 3-isobutyl-1-methylxanthine (IBMX; a non-specific PDE inhibitor) and vinpocetine (Vinp; a PDE1 inhibitor). Balb\/c mice were randomized to five treatment groups: control, ovalbumin (OVA), OVA + IBMX, OVA + Vinp, and OVA + dexamethasone (Dex). All mice were sensitized and challenged with OVA, except for the control group. IBMX, Vinp, or Dex was intraperitoneally administered 1 h before the challenge. Vinp treatment significantly inhibited the increase in airway hyper-responsiveness (<jats:italic>P<\/jats:italic>&lt;0.001) and reduced the number of inflammatory cells, particularly eosinophils, in the lungs (<jats:italic>P<\/jats:italic>&lt;0.01). It also ameliorated the damage to the bronchi and alveoli and decreased the OVA-specific IgE levels in serum, an indicator of allergic inflammation increased by OVA (<jats:italic>P<\/jats:italic>&lt;0.05). Furthermore, the increase in interleukin-13, a known Th2 cytokine, was significantly decreased by Vinp (<jats:italic>P<\/jats:italic>&lt;0.05), and Vinp regulated the release and mRNA expression of macrophage inflammatory protein-1\u03b2 (MIP-1\u03b2) increased by OVA (<jats:italic>P<\/jats:italic>&lt;0.05). Taken together, these results suggest that PDE1 is associated with allergic lung inflammation induced by OVA. Thus, PDE1 inhibitors can be a promising therapeutic target for the treatment of asthma.<\/jats:p>","DOI":"10.1371\/journal.pone.0251012","type":"journal-article","created":{"date-parts":[[2021,4,29]],"date-time":"2021-04-29T17:49:53Z","timestamp":1619718593000},"page":"e0251012","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":9,"title":["Vinpocetine
