Phosphodiesterases (PDEs) are a family of enzymes that modulate the immune response, inflammation, and memory, among many other functions. There are three types of PDEs: cAMP-specific, cGMP-specific, and dual-specific.

cAMP is a messenger molecult - it carries information around.

PDEs also act as messengers as per the above.

Maybe somebody can explain it better in simple terms.
