4 foreign antigens presented on class i mhc molecules

This preview shows page 2 - 3 out of 3 pages.

4. Foreign antigens presented on class I MHC molecules stimulate cell destruction. Self-antigens are not recognized by the T cells and do not stimulate cell destruction. 5. A different process occurs. Phagocytes such as macrophages ingest foreign particles such as viruses and bacteria by endocytosis. 6. They are broken down into fragments within a vesicle. Pg 592: 1 When a pathogen enters the body 4 Macrophages with antigen fragments displayed on their surfaces. 12 B cells also come in millions of different types and each able to recognize a particular antigen. 13 By T-helper cells, differentiate into plasma cells. 15 Antibodies bind to the antigens on the surface of the pathogens, marking them for destruction by macrophages. 18 It is what is gives you immunity to some diseases after you have had them once or after you have been vaccinated.
