Final answer:
Defects in the complement pathway are associated with immune complex (IC) diseases because the complement system plays a crucial role in removing immune complexes (ICs) generated during B-cell immune responses. The correct option is 1. True
Step-by-step explanation:
True. Defects in the complement pathway are indeed associated with immune complex (IC) diseases because the complement system plays a crucial role in removing immune complexes (ICs) generated during B-cell immune responses.
The complement pathway is part of the immune system and consists of a series of proteins that work together to enhance the immune response against pathogens.
One of the main functions of the complement system is to recognize and eliminate immune complexes, which are formed when antibodies bind to antigens on the surface of pathogens or other foreign substances.
The complement system can activate different pathways, such as the classical pathway, which is initiated by the binding of complement component C1 to an antigen-antibody complex.
Once activated, the complement system can lead to the destruction of immune complexes through various mechanisms, including the recruitment of immune cells and the lysis of pathogens. The correct option is 1. True
