Leukocyte infiltration in response to I/R injury is a well-known but p
oorly understood phenomenon. The contribution of neutrophils in this p
rocess is still controversial. Despite numerous data, little is known
about exact numbers of infiltrating neutrophils, The role of monocytes
/macrophages in this process is even more unclear. The role neutrophil
s in the kidney and other organs was reviewed. The variability in mode
ls and methods for neutrophil quantification were examined, along with
carrying out a critical overview of depletion and anti-adhesion appro
aches. Nevertheless, the exact role attributed to neutrophils in the I
/R process remains unclear.
