Q&As

How do genetic variations in CD55 influence susceptibility to complement-mediated disorders, and what are the molecular mechanisms involved?

Genetic variations in CD55 may influence susceptibility to complement-mediated disorders by affecting the protein's ability to regulate complement activation. This can lead to conditions like paroxysmal nocturnal hemoglobinuria (PNH).

How does CD55 contribute to the modulation of immune responses beyond its role in complement regulation?

CD55 has immunomodulatory functions beyond complement regulation, influencing T cell responses and contributing to the maintenance of immune tolerance.

What role does CD55 play in protecting cells from complement-mediated lysis, and how does it contribute to immune evasion?

CD55 protects cells from complement-mediated lysis by preventing the formation of membrane attack complexes. This contributes to immune evasion by pathogens and self-cells alike.

Can you elaborate on the structural domains of CD55 and how they mediate its interactions with complement components?

CD55 consists of extracellular domains responsible for interactions with complement proteins, particularly C3b and C4b. These interactions prevent the formation of membrane attack complexes on host cells.

Can you discuss the involvement of CD55 in various diseases, including autoimmune disorders and infectious diseases?

CD55 dysregulation is associated with autoimmune disorders, where it may contribute to immune system overactivity. Additionally, some pathogens exploit CD55 to evade host immune responses.
