Antigen- Intro Flashcards
What are substances that are capable of stimulating immune responses, specifically activating lymphocytes?
Antigens
What is a portion of an antigen that binds to immune cells?
Epitopes
What are normally present on the surface of a molecule?
Probable antigenic determinants
What is a large complex molecule that contains many different epitopes and stimulates multiple immune responses?
B cell epitopes
What binds directly to their epitopes?
B cell receptor
What mostly recognizes the conformation of an epitope?
B cell receptor
What also recognizes lineal epitope?
B cell receptor
What are peptides of 8-10 amino acids presented by MHC 1 molecules and peptides of 13-25 amino acids presented by MHC 2 molecules?
T cell epitopes
What comes from larges molecules such as bacteria?
T cell epitopes
Where are T cell epitopes located?
Anywhere in a large molecule
What recognizes processed peptides in the context of MHC molecules on the cell surface of antigen-presenting cells (APC’s), an innate immune cell subset?
T cell receptor
