What does complement proteins do?
Complement is part of the innate immune system (one you are born with). It consists of small protein molecules that circulate in the blood stream. Complement has three pathways, The classic pathway; The alternative pathway; and the lectin pathway. In the classical pathway, complement is activated by triggers such as the binding of an antigen to an antibody. In the alternative pathway, Complement is part of the natural immune system and complement assist in the opsonization, or the marking of an antigen to be destroyed by a phagocyte. This like the antigen has been marked with black marker so that a killer cell (phagocyte-cell eater) can find it to eat it. Finally the lectin pathway, which is similar to the classical pathway in terms of structure but this pathway starts with lectin or ficolin binding to sugars. After activation complement can trigger any number of events such as opsonization, chemotaxis, inflammation, and lysis (breaking) of cells.
How does the innate immune system interact with the adaptive immune system?
The complement system is a series of about 20 proteins that are involved in a cascade effect during an immune response. Complement is generally divided up into 3 pathways: classical, lectin, alternate. The classical pathway involves a complement protein binding to an antigen-antibody complex (and thus its role in adaptive immunity). Whereas in the alternate pathway, complement (C3) binds directly to the foreign cell( usaully bacteria). Thus its repsonse is non specific and therefore is also part of the innate imune system.
Can cell membrane mannose be used for adherence?
Yes it can. In fact, this is specifically the target of Type 1 Fimbriae. Many pathogenic Enterobacteriaceae posses this kind of Fimbriae as a virulence factor. These Fimbriae contain receptor domains similar to the MBL (Mannose Binding Lectin) present in blood plasma. The difference is that the human MBL recognizes the pathogen's Mannose residues and can initiate the MB-Lectin pathway, activating the complement cascade. This leads to pathogen opsonization. Cheers.

How does Lectin affect the ABO blood types of elders?
You can monitor Lectin by reading up on the foods that contain it and how much you are allowed to consume. Your doctor will inform you on your medications and the Lectin.

How is ricin connected to castor oil?
The active poison in the castor bean is ricin, a deadly water-soluble protein called a lectin.
Why does undercooked kidney beans make you sick?
Toxins. Lectin phytohaemagglutinin, this will make your stomach upset and cause vomiting and diarrhea to say the least.
Weight loss foods for blood type B-.?
For Type Bs, the biggest factors in weight gain are corn, buckwheat, lentils, peanuts and sesame seeds. These foods have different lectin that affect the efficiency of the metabolic process, resulting in fatigue, fluid retention, and hypoglycemia. The gluten lectin in wheat germ and whole wheat products also adds to the problems cause by other metabolism-slowing foods.

What stabilized c4bc2a complex?
C4bC2a is a C3 convertase, which is stabilized by the surface of the acvtivator (activating substance). It only will cleave C3, and can only be activated in one of three pathways: classical, lectin and alternative.
