The slow neutrophil rolling allows neutrophils to sense signals such as interleukin (IL)-8, tumor necrosis factor (TNF)α, granulocyte macrophage colony-stimulating factor (GM-CSF), or N-formyl-methionine-leucine-phenylalanine (fMLP) from damaged cells or infection[5,9-13], and activate integrin adhesion molecules such as CD11b and CD18[6,7,9,14-16]. Here, TNF is linked to infection.
