Getting to know Immunology!
Across
- 2. Cell that is able to present antigens via MHC molecules to T cell receptors on T cells (Antigen presenting cells).
- 5. Receptors on B cells that bind antigens and transmits signal 1 to activate B cells (B cell receptor).
- 8. End stage of disease in HIV infection (Acquired immune deficiency syndrome).
- 9. Cell adhesion molecule.
- 10. Immune response.
- 11. Cytokines produced by macrophages and T cells that is highly pro-inflammatory.
- 15. Large granular lymphocyte that serves as a innate effector cell and induces apoptosis of target cells.
- 19. CD4 T cells involved in stimulating B cells to produce antibody against extracellular pathogens.
- 21. Part of antibody that consists of carboxy terminal halves of the two heavy chains disulfide-bonded to each other. Responsible for antibody effector function.
- 22. Immunoglobulin that is expressed on B cell surface (slg).
- 25. Cytokine produced by cD4 TH1 cells, CD8 T cells and NK cells. Primary actions are to act with IL-12 and induce TH1 differentiation and fully activate macrophages.
- 26. Family name for cytokines that help cells to resist viral infections.
- 27. The Ag receptor on T cells.
- 29. Protein family to which antibodies and B cell receptors belong (Ig).
- 31. Lymphocyte that upon activation can differentiate into plasma cells that secrete antibodies or into B memory cells.
Down
- 1. Cell wall component of gram negative bacteria which can be bound by TLR-4 on macrophages and dendritic cells (LPS).
- 3. End product of the Complement cascade that can kill pathogens directly by forming a pore in pathogen membrane leading to lysis (MAC).
- 4. CD4 T cells involved in activating macrophages and promoting CTL responses against intracellular pathogens.
- 6. Adaptive immune responses in which there is a major role for effector T cells (CMI)
- 7. T cells that express the co-receptor protein CD4 that once activated, it differentiates into distinct Thelper phenotypes with roles in adaptive immunity.
- 12. Molecule that is recognized as it original structure by antibodies, B cell receptor or T cell receptor (Ag).
- 13. T cell responsible for suppressing immune response.
- 14. Human immunodeficiency virus
- 16. Thymus-derived lymphocyte that can be either CD4 or CD8.
- 17. T cells that express co-receptor protein CD8 that once activated, it differentiates into cytotoxic T cells.
- 18. Designation for a family of cell surface molecules involved in the presentation of peptide antigens to T cells (Major histocompatibility complex).
- 20. Member of TNF receptor family expressed on certain cells that makes them susceptible to being killed by cells expressing Fas ligand.
- 21. Part of antibody responsible for antigen binding.
- 23. Transcription factor that causes several tissue-specific genes to be transcribed by a subpopulation of epithelial cells in the thymus (Autoimmune regulator).
- 24. Soluble acute phase response protein than can bind mannose on pathogens; can activate the lectin pathway of Complement (MBL).
- 25. Chemical messengers secreted by immune cells that help in their communication with other cells (IL).
- 28. Immunoglobulin that is secreted by plasma cells (Ab).
- 30. Transcription factor that helps activate the expression of many pro-inflammatory genes.
