Figure 2: Up-regulation of CD11b and CD66b: By cytofluorometry up-regulation of CD11b (A) and CD66bb (B) on neutrophils stimulated by EPS was determined (thick line: CD11b or CD66b, respectively, after exposure to EPS; thin line: constitutive expression). C shows the summary of data for 9 individuals (each symbol represents one individual). D EPS induced oxygen radical production, and increased production following stimulation with E. coli (measured in a whole blood assay); E Induction of oxygen radical production in isolated cells (in D and E data of different individuals are summarised).
