The response of the immune system to any trauma starts at the moment o
f injury. Macrophages are activated and produce proinflammatory mediat
ors. All the stimuli of the cytokine system lead to a final common pat
hway where a therapeutic approach might start. However, any strategy o
f cytokine therapy cuts both ways. There are a lot of data derived fro
m in vitro and animal studies. Both the classification and the clinica
l application of these results are rather difficult. Some therapeutic
concepts seem promising, but the advantages and disadvantages have to
be carefully considered. The aim of all strategies must be to improve
or adjust the patient's immune defence system. First of all,the patien
t, the disease or the specific injury has to be treated, not only the
mediators and cytokines. The philosopher's stone has not been found ye
t. There are several approaches, but it is still a long and difficult
process to find new insights and effective treatments.
