Across
  1. 1. cell adhesion molecule
  2. 4. “Cytotoxic T lymphocytes”: CD8+ T cells with the effector function of targeting and killing virally infected cells and tumor cells by apoptosis
  3. 6. “Cell mediated immunity”: adaptive immune responses in which there is a major role for effector T cells
  4. 9. T cell, T cells that express the co-receptor protein CD8 which upon activation differentiate into cytotoxic T lymphocytes (CTLs)
  5. 10. “Human leukocyte antigen”: name of MHC gene complex and proteins in humans
  6. 12. “Complementarity determining regions”: the regions of the antigen binding loops of Ig molecules, antibodies and T cell receptors that come into contact with antigen
  7. 14. “Acquired immune deficiency syndrome”: the end stage of disease in HIV infection
  8. 16. Transcription factor expressed in Treg cells that is needed for Treg cell function
  9. 18. “Cluster of differentiation”: designation for specific cell-surface molecules on immune cells that help to differentiate one immune cell from another
  10. 19. “Human Immunodeficiency Virus”
  11. 21. “Mannose-binding lectin”: soluble acute phase response protein that can bind mannose on pathogens; can activate the lectin pathway of Complement and acts as an opsonin
Down
  1. 2. “Major histocompatibility complex”: designation for a family of cell surface molecules involved in the presentation of peptide antigens to T cells
  2. 3. “Interleukin”: general designation of many of the different cytokines, chemical messengers secreted by immune cells that help in their communication with other cells
  3. 5. “lipopolysaccharide”: a cell wall component of gram negative bacteria which can be bound by TLR-4 on macrophages and dendritic cells
  4. 6. T cell, T cells that express the co-receptor protein CD4 which upon activation differentiate into distinct Thelper phenotypes with different roles in adaptive immunity
  5. 7. “Immunoglobulin”, protein family to which antibodies and B-cell receptors belong
  6. 8. “Dendritic cell”: a type of APC that presents antigen in the context of MHC to T cells
  7. 10. “Highly active anti-retroviral therapy”: multiple drug treatment for HIV infection
  8. 11. “Antigen”: a molecule that is recognized in native (original) structure by antibodies or B cell receptor, or a peptide that is presented by MHC molecules to T cell receptor
  9. 13. “C-reactive protein”: acute phase protein that binds to phosphocholine, a constituent of certain bacteria, that can trigger Complement activation and acts as an opsonin
  10. 14. “Antibody”: immunoglobulin secreted by plasma cells
  11. 15. “Nuclear factor of activated T cells”: a key transcription factor that is required to bind to the IL-2 promoter to cause IL-2 transcription
  12. 17. “Antibody dependent cellular cytotoxicity”: a mechanism NK cells use to induce apoptosis in virally infected cells or tumor cells
  13. 20. “Immune Response”
