Excerpt

The interaction of endotoxins (lipopolysaccharides (LPS)) from Gram-negative bacteria with peripheral blood mononuclear cells leads to the assembly of a receptor cluster composed from mCD14, CD11b/CD18, TLR4, CD16A and CD36 [1, 2]. It is well known that the main signal transducing receptor complex is TLR4/MD-2 while mCD14 is involved in the recognition of S or R endotoxin's glycoforms [3, 4]. A growing body of evidence indicates that the CD11b/CD18 receptor plays the significant role in the endotoxin signaling machinery because it can influence TLR4-mediated cell activation [5]. So, using mAbs, we carried out experiments to elucidate the influence of CD11b inhibition on neutrophil priming by endotoxins for N-formyl-methionyl-leucyl-phenylalanine (fMLP)-induced respiratory burst. …
