Research Excerpts

Overview

Apyrase (APY) is a nucleoside triphosphate (NTP) diphosphohydrolase. Ecto-apyrase is an enzyme proposed to control the concentration of extracellular nucleotides. Apyrases are a recurrent feature of secretomes from numerous species of parasitic nematodes.

Effects

Apyrases have been suggested to play important roles in plant nutrition, photomorphogenesis, and nodulation. Apyrase activity has been found in tissue of all investigated plant species.

Treatment

Apyrase was associated with attenuated neutrophil graft sequestration and less evidence of tissue inflammation. Apyrase treatment for 20 h in the absence of stimulation did result in moderate diminution of neural activity.
