Activation of complement is known to accompany burn injury. To study deposition of complement proteins within tissue traumatized by burn we employed the technique of intravital microscopy using a murine dorsal skinfold chamber model. C3, factor H, factor B, HSA, and transferrin were labeled fluorescently and injected into the tail vein of mice which had been subjected to a small third degree burn within the skin fold. Only C3 and factor H deposited within blood vessels of the traumatized tissue. Binding was specific because it occurred only in and proximal to burn sites, and neither C3 nor factor H was observed to accumulate in blood vessels of healthy tissue. Furthermore, fluorescently labelled HSA, factor B, and transferrin all failed to deposit at or around burn loci. The deposition of C3 and factor H occurred within 10 min of injury and was intravascular occurring in major blood vessels, capillaries, and post-capillary venules, with little evidence of accumulation in the interstitium. Since both C3 fragments and factor H are recognized as adhesion molecules by granulocyte receptors, these deposited proteins could promote leukocyte accumulation, thereby contributing to an initiation of an inflammatory cascade at a site of burn injury.
