Study Notes
Hypersensitivity Reactions
- Components that can trigger hypersensitivity reactions include allergens, haptens, and autologins.
Types of Hypersensitivity Reactions
- Type I hypersensitivity reaction is characterized by immediate or anaphylactic response.
- Type II hypersensitivity reaction is antibody-mediated cytotoxic.
- Type III hypersensitivity reaction is immune complex-mediated.
- Type IV hypersensitivity reaction is delayed or cell-mediated.
The Complement System
- The complement system is a group of proteins that works with antibodies to help eliminate pathogens from the body.
- Complement proteins are synthesized in the liver.
Characteristics of the Complement System
- The complement system is heat-labile, meaning it is inactivated at high temperatures.
- There are over 30 proteins present in the complement system.
- The term 'complement' means "to complete" or "to fill in", referring to the system's role in completing the immune response by working in conjunction with antibodies.
