The role of phosphodiesterase 4 (PDE4) and cAMP in controlling inflammation2-4

learn about the role of PDE4 and cAMP in controlling inflammation

Inflammatory cell

Visual representation based on preclinical evidence

  • Cyclic adenosine monophosphate (cAMP) is a second messenger for a variety of inflammatory mediators2
  • PDE4 is a cAMP-specific PDE that has been shown to degrade cAMP to AMP in inflammatory cells1,2,5
  • The balance between cAMP and AMP within a cell may modulate the expression of pro-inflammatory and anti-inflammatory mediators4

Inflammatory cell

Visual representation based on preclinical evidence

  • By elevating cAMP levels, Otezla® (apremilast) is thought to indirectly modulate production of inflammatory mediators3,4
  • The specific mechanism(s) by which apremilast exerts its therapeutic action in patients with psoriatic arthritis is not well defined1
