MAP-2:CD55 chimeric construct effectively modulates complement activation.

The complement system is a complex, tightly regulated protein cascade involved in pathogen defense and the pathogenesis of several diseases. Thus, the development of complement modulators has risen as a potential treatment for complement-driven inflammatory pathologies. The enzymatically inactive MAP-2 has been reported to inhibit the lectin pathway by competing with its homologous serine protease MASP-2.
