Question
Place the steps of extravasation of neutrophils to infected tissue sites in the correct chronological order. (1 = earliest event, 7 = latest event) Binding of neutrophil sialyl-Lewis^x (s-LE^x) carbohydrates to selectins Rolling of neutrophils is arrested Expression of selectins on surface of helium by cytokines IL-1beta and TNF-alpha Binding of CXCL8 to CXCLR1 on neutrophils Diapedesis of neutrophils between endothelial cells Neutrophil integrins LFA-1 increase their affinity for endothelial adhesion molecules ICAM-1 Migration of neutrophils to sites of infection following CXCL8 chemokine gradientExplanation / Answer
The steps of extravasation of neutrophils ro infected tissue sites in the correct chronological order (from first step to last step) are as follows
