The Complement System

The complement system is part of the immune system. Its main function is to guide phagocytic cells and clear microbes and damaged cells from an organism. In this video, we introduce the role of C3 protein and how the protein can kill bacteria with/without the help from the other parts of the immune system. The video ends with an illustration of how those powerful tiny bombs (proteins) contribute to the progression of Alzheimer’s disease.

This video was made by McMaster students Jiawen Deng, Jiawei Sun, Simran Saini, Gurratan Gill in collaboration with the McMaster Demystifying Medicine Program.
