Question
Which of the following is involved in the hemolysis in autoimmune hemolytic anemia?
Question 5
Select one:
- Mannose-Binding Lectin
- C1q
- Natural Killer Cells
- IgD
Solution
In autoimmune hemolytic anemia, the body's immune system mistakenly produces antibodies against its own red blood cells leading to their destruction, a process known as hemolysis. This process is typically mediated by two types of antibodies: IgG and IgM.
However, from the options provided, the closest answer would be C1q. C1q is a protein involved in the classical pathway of the complement system, which is part of the immune system. When antibodies bind to antigens on the red blood cells, they can activate the complement system, leading to the formation of a membrane attack complex that causes cell lysis.
So, the answer is C1q.
