Phosphodiesterase 4B (PDE4B) is a member of the phosphodiesterase family of proteins that plays a critical role in regulating intracellular levels of cyclic adenosine monophosphate (cAMP) by controlling its rate of degradation. It has been demonstrated that this isoform is involved in the orchestra of events which includes inflammation, schizophrenia, cancers, chronic obstructive pulmonary dise...
Los niveles intracelulares de nucleótidos cíclicos (cAMP, cGMP) tienen un papel esencial en la regulación de múltiples funciones de las células inmunes. Las fosfodiesterasas (FDEs) son un grupo grande de enzimas que ejercen un papel muy importante en la regulación de los niveles intracelulares de nucleótidos cíclicos. La pentoxifilina es un inhibidor no específico de FDE que tiene diferentes ef...
In a guinea pig model of allergic asthma, we investigated the effects of the selective phosphodiesterase inhibitors rolipram (phosphodiesterase 4-selective), Org 9935 (phosphodiesterase 3-selective) and Org 20241 (dual phosphodiesterase 4/phosphodiesterase 3-selective), administered by aerosol inhalation in approximately equipotent bronchodilatory doses, on allergen-induced early and late asthm...
OBJECTIVE To compare the direct pulmonary vasodilating activity and specificity of phosphodiesterase-5 (zaprinast) and phosphodiesterase-3 (milrinone) inhibitors on the pulmonary vascular (PV) bed of the spontaneously breathing cat with an intact chest. DESIGN Prospective, randomized animal study. SETTING Laboratory of university hospital. SUBJECTS Experiments were performed in vivo in in...
