“…Experimentally, in acute forms of GN, neutrophils and monocytes are critical to the response, while in more prolonged forms of GN, T cells and macrophages are prominent. 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 The mechanisms whereby leukocytes are recruited to the glomerulus differ from those in postcapillary venules, where the classical rolling/adhesion/transmigration sequence of leukocyte–endothelial cell interactions underpins leukocyte recruitment. In glomerular capillaries, leukocytes can undergo intravascular arrest, retention and migration in the absence of inflammation, and without an initial rolling interaction.…”
