How Do You Spell MEMBRANE ATTACK COMPLEX?

1. The Membrane Attack Complex (MAC) is a complex formed as part of the immune response in the body, specifically in the complement system. Complement proteins are a group of proteins that work together to form a defense mechanism against foreign substances such as bacteria and viruses. When an infection or foreign invader is detected, a cascade of events in the complement system is initiated to eliminate the threat.

   The Membrane Attack Complex is the final step in this cascade, where several complement proteins assemble together to form a pore-like structure on the surface of the target cell. This structure, known as the MAC, leads to the lysis or destruction of the targeted cell. The MAC is composed of several complement proteins, including C5b, C6, C7, C8, and multiple units of C9.

   Upon formation, the MAC inserts itself into the membrane of the target cell, creating a pore that disrupts the integrity of the cell membrane. This disruption leads to the loss of the membrane's permeability barrier, causing uncontrolled passage of ions and molecules, leading to cell death.

   The Membrane Attack Complex plays a crucial role in eliminating foreign or infected cells, preventing the spread of pathogens and supporting the immune system's defense mechanisms. This complex mechanism is an important component of the body's innate immune response and plays a vital role in defending against infections and maintaining overall health.
