High levels of dATP and dADP, accompanied by ATP depletion, were found in the platelets of two ADA-deficient children with severe combined immunodeficiency (SCID). In vitro studies demonstrated that even normal platelets had the ability to make dATP from deoxyadenosine (dAR) under physiological conditions. This capability was greatly enhanced by conditions simulating ADA deficiency. These results question whether the platelet has a specific role in the normal immune response.
