Increased adenosine triphosphatase in leukocytes of asthmatic children.
Adenosine triphosphatase (ATPase) activities were compared in leukocytes of asthmatic and nonasthmatic children. Both Mg(2+)- and Ca(2+)-dependent ATPase activities were significantly elevated in two membrane fractions (59 to 66%) and in a superntant fraction (68 to 72%) prepared from sonicated leukocytes of asthmatic subjects. Intact cell surface or ecto ATPase was also elevated (67 to 76%) in...
