C5a Receptor "Knock out" Mice

Description:

C5a Receptor "Knock out" Mice

The Technology: A researcher at the University of Texas Health Science Center at Houston (UTHealth) has developed complement anaphylatoxin C5a receptor-deficient mice on C57Black6 genetic background via the disruption of the C5aR gene. It is becoming increasingly clear that C5aR plays an important role in the regulation of many physiological and cellular responses characteristic of acute shock and that the C3aR functions to temper the immune response in acute shock. This well-characterized model lacks the complement C5a, making it an excellent model for studying the relationship between C5a and septic shock.
