Question

Quizplus · Accepted Answer

The lectin pathway for complement action is initiated by binding of mannose-binding lectin (MBL) to mannose on the surface of microbes. This initiates a cascade of complement activation that ultimately leads to the deposition of membrane attack complexes (MACs) that lyse the microbe. The lectin pathway is an important component of the innate immune response and helps to clear microbes from the body.
