Survival of transfused CD18-positive granulocytes and their chemiluminescent response in a heifer with leukocyte adhesion deficiency.

Granulocyte transfusion (GT) was performed in an 8-month-old heifer with leukocyte adhesion deficiency (BLAD) to monitor the changes in transfused CD18-positive neutrophils and associated neutrophil chemiluminescent (CL) response in beta 2-integrin-deficient host. The CD18-positive neutrophils were detected in blood from the BLAD heifer during the first 3 hr after 2.6 x 10(9) cells were infused by GT, and disappeared by 5 hr after GT. The CL response of neutrophils was increased 1.7 to 2.8-fold in the BLAD heifer during the first 3 hr after GT, thereafter CL response decreased gradually from 2 to 5 hr after GT.
