Chapter 13- Microbiology

8. CD8 lymphocytes that recognize antigens presented on MHCI and destroy infected or abnormal cells
10. T Lymphocytes that suppress or limit immune responses to prevent excessive inflammation
13. One of the two polypeptide chains forming the T-Cell receptor
14. one of the two larger polypeptide chains that form a B-Cell receptor or antibody
15. The second polypeptide chain forming the T-Cell receptor
18. specific portion of an antigen recognized by an immune receptor
19. adaptive immune lymphocytes that mature in the thymus and participate in cell mediated immunity
20. One of the two smaller polypeptide chains that form a B-Cell receptor or antibody
22. bridge chemical bond that holds antibody polypeptide chains together
23. another name for an antibody
24. receptor composed of alpha and beta chains that recognizes antigen fragments presented by MHC molecules

1. long lived B cell that enables a faster response to an antigen encountered previously
2. Y shaped membrane bound antibody that directly recognizes specific antignes
3. CD4 lymphocytes that recognize antigens presented on MHCII and coordinate immune response
4. protionn of an antigen receptor that determines which antigen it recognizes
5. portion of a membrane bound receptor that anchors it to the cell membrane
6. protein on a lymphocyte that recognizes a specific antigen or antigen fragment
7. adaptive immune lymphocytes that mature in bone marrow and can differentiate into antibody producing plasma cells
9. surface protein for helper T cells that recognize MHCII
11. Activated B cell specialized in producing a secreting antibodies
12. conserved portion of an antigen receptor that varies less than its antigen binding region
16. ability of an immune receptor to recognize a particular antigenic structure
17. specialized epithelial cells that transport antigens from mucosal surfaces to underlying immune tissues, they are not lymphocytes
21. Surface protein for cytotoxic T cells. that recognize MCHI
