a. Could the immune system utilize this fact to destroy foreign cells that have invaded the body?
b. How might cells of the immune system disrupt membranes of foreign cells?
Here's how it can work. Almost all cells, including the many cells of the body's immune system can secrete proteins with very specialized functions. An immune cell secretes a special protein that recognizes foreign cells. Then they bind to the surface of these foreign cells. How? By interacting with membrane proteins ...
The solution to these questions lies in understanding the nature of protein-protein and protein-lipid interactions. Specifically, I explain the role of integral membrane "pore" proteins.
