Polymorphonuclear (PMN) leukocytes were obtained from healthy individuals. "time" indicates time at which transcript levels were analyzed (hours). "treatment" indicates whether the polymorphonuclear leukocytes were untreated (ctrl) or treated with Anaplasma phagocytophilum (AP), Staphylococcus aureus (SA), HL60 cell lysate (uninf), heat-killed Anaplasma phagocytophilum (hkAP), or heat-killed HL60 cell lysate (hklys).
