Complement System Activation Pathways Quiz

Complement component C5 is associated with recurrent bacterial infections.

The Classical Pathway of the Complement system can be triggered by Mannose-binding lectin (MBL).

Deficiency in complement component C3 can lead to an increased susceptibility to a wide range of bacterial infections.

Complement component C1 is associated with autoimmune diseases like Systemic Lupus Erythematosus (SLE).

Opsonization is a clinical manifestation of the complement system in immunity.

The Lectin Pathway of the Complement system is triggered by spontaneous hydrolysis of C3 in the blood stream.

The complement system consists of 30 soluble and membrane-bound proteins.

In the complement system, proteins are designated with a letter followed by numbers like A1 to A9.

The complement system is only involved in innate immunity, not adaptive immunity.

Opsonization is the process of removing complement proteins from the body.

Activated complement components are designated by adding the letter 'a' to the symbols.

In the complement system, a cascade of proteins refers to a series of biochemical reactions where each protein inhibits the next one.

During T cell development, thymocytes originate from the spleen.

Thymocytes migrate to the liver for T cell development.

DP thymocytes express only CD4 receptor during early thymocyte development.

Thymocytes that fail to undergo positive selection undergo proliferation.

Positive selection in T cell developmental stages occurs when DP thymocytes recognize self-MHC molecules.

Negative selection in T cell development leads to autoimmunity.
