FIGURE 1 Pathogenesis of transfusion-related acute lung injury. The presence of antileukocyte antibodies and/or biologically active lipids from cell membrane fragments in donor blood triggers an inflammatory response, granulocyte activation, and degranulation and injury to the alveolar-capillary membrane. Activated macrophages secrete inflammatory cytokines that further perpetuate the inflammatory reaction. C = complement; HLA = human leukocyte antigen; IL = interleukin; LPS = lysophosphatidil choline; PAF = platelet activating factor; TNF = tumor necrosis factor; 5b, NA, NB = neutrophil antigens.
