How does CD55 protect human cells from complement-mediated lysis?
Understand the Problem
The question is asking about the function of CD55 in protecting human cells from being destroyed by the complement system, specifically identifying how it performs this protective role among the given options.
Answer
CD55 protects human cells from complement-mediated lysis by accelerating the degradation of C3 convertase.
The final answer is that CD55 protects human cells from complement-mediated lysis by accelerating the degradation of C3 convertase.
Answer for screen readers
The final answer is that CD55 protects human cells from complement-mediated lysis by accelerating the degradation of C3 convertase.
More Information
CD55 is crucial for protecting cells from being overly damaged by the body's own immune system during inflammation.
Tips
A common mistake is not understanding that CD55 does not prevent the initial stages of complement activation but rather accelerates the breakdown of a critical enzyme in the cascade.
