Across
  1. 4. protein created by B cells that bind to specific antigens
  2. 5. when T cells only recognize and react to antigens presented in context of specific MHC molecules
  3. 7. important signaling protein or cytokine that WBCs make, especially in T lymphocytes
  4. 8. protein on surface of T cells that are co-stimulatory recpetors. Enhances signaling of TCR and helps with cytokine production by binding to ligands CD80/B71 and CD86/B72 that are expressed on APCs
  5. 9. also called CD4+ T cells, important in adaptive immune system. In charge of immune responses that release cytokines and chemokines, which help trigger other immune cell functions for cells like B cells, macrophages, and cytotoxic T lymphocytes
  6. 12. process when immune cells increase in number with cell division
  7. 15. protein on surface of T cells that control T cell activation and maintain immune tolerance & suppress autoimmune reactions.
  8. 16. type of receptor on B cells that notice free antigens
  9. 18. type of molecules that present antigens to T cells
  10. 19. T cell marker in cytotoxic T cells, bind to MHC class I
  11. 21. small masses of lymphatic tissue in lining of small intestine, specifically ileium. Important for GALT and monitor contents of digestive tract, trigger immune responses
  12. 23. second signal needed for full T cell activation and facilitated by APCs
  13. 24. Marker for helper T cells, binds to MHC class II
  14. 26. kind of secondary lymphoid tissue in mucosal membranes in body. Trigger immune responses to antigens found on mucosal surfaces (gastrointestinal, respoiratory, genitrouinary tracts). encapsulated and directly samples antigens from outer surrounding with epithelial cells/M cells
  15. 28. molecules important for triggering immune responses by presenting peptide antigens to CD4+ T cells. Found mostly on surface of APCs. Important in cellular and humoral immunity. Also important in autoimmune disease and organ transplants.
  16. 29. type of immune cell that works to connect innate and adaptive immune systems. Share features with T cells and NK cells
  17. 30. creates signals from the immune system that helps communicate responses
Down
  1. 1. kind of lymphocyte that continues to react fast against future infections
  2. 2. type of WBC, also CD8+ T cell, or killer T cell that is an important role in adaptive immune system, direct recognition and destruction of infected cells in a antigen-specific way
  3. 3. specialized blood vessels within lymph nodes and other secondary lymphoid organs. Important for facilitating circulation in lymphocytes in blood to immune tissues and triggering immune responses.Are plump, cube shaped endothelial cells that express adhesion molecules that allow specific recruitment of lymphocytes
  4. 6. kind of cell that triggers T cell responses
  5. 10. specialized cells (ex. dendritic, macrophages) that present antigens
  6. 11. kind of B cell that secretes a lot of antibodies
  7. 13. how strongly an antibody bonds to an antigen
  8. 14. receptors on T cells that notice antigen-MHC complexes
  9. 17. procedure when B cells alter their kind of antibody it makes
  10. 20. small gland in lymphatic system. Creates WBCs to aid in immune system and its functions
  11. 22. specialized epithelial cells in gut-associated lymphoid tissue and othe rmucosal tissues. sample antigens and pathogens in gut lumen and move them to immune cells below epithelium, trigger immune response
  12. 25. family of cell surface proteins important for adaptive immune system. Present short peptide fragments from proteins degraded w/i cell to T cells. Allows immune system to recognize and react to intracellular pathogens.
  13. 27. triggers an immune response
