MIF and acute respiratory distress syndrome: It is noteworthy that in mice CXCL was the pathway expressed in the pulmonary ALI, whereas MIF was expressed in all of control, pulmonary and extra-pulmonary ALI, except in the extra-pulmonary ALI where it was at a higher state of expression, whereas in human samples both CXCL and MIF were sepsis-related ARDS group-specific.
