Over 30 proteins and protein fragments make up the complement system, including globulin fraction of blood serum and can serve as opsonins.
42.
Ratnoff had a long association with immunologist Irwin Lepow, and they conducted some of the early research on inhibition of the complement system.
43.
This allows the bacteria to live intracellularly, where they are protected from extracellular immune system factors such as the complement system and antibodies.
44.
The complement system of the immune response also involves a complex sequential proteolytic activation and interaction that result in an attack on invading pathogens.
45.
Plasmin, in addition to lysing fibrin clots, also cleaves the complement system component C3, and fibrin degradation products have some vascular permeability inducing effects.
46.
Antibodies can be highly active and can attack RBCs and bind components of the complement system to cause massive hemolysis of the transfused blood.
47.
Depression of C3 occurs in autoimmune disorders as the complement system is activated and the C3 becomes bound to immune complexes and removed from serum.
48.
To survive, the body uses natural inhibitors that keep the killer molecules of the complement system in check by blocking certain points of the cascade.
49.
It is possible to update x _ 1 alongside x _ 2 during the iteration for the Schur complement system and thus obtain an efficient algorithm.
50.
These include the complement system activated by bacteria and the coagulation and fibrinolysis systems activated by necrosis, e . g . a burn or a trauma.
