Presentation Transcript

  1. How an APC activates T-Cells By: Cord Pryse & Kyann Plandel

  2. How T-cells recognize antigens A cell that can process antigens like a dendritic cell, ingests the antigen Enzymes in the antigen-processing cell break the antigen into fragments The antigen fragments are transported to the cells surface The t-cell receptor recognizes the antigen fragment and attaches to the part of the HLA molecule

  3. How T-Cells recognize Antigens

  4. The Immune system contains three types of APCs Macrophages 2. Dendritc Cells 3. B cells

  5. A picture of an APC

  6. A macrophage eating bacteria

  7. How Lymphocytes produce Antibodies

  8. The Omentum Macrophage

  9. An APC activating a T-cell

  10. T-Cell activation

  11. A system used by killer T-Cells

  12. Key Terms APC: APC stands for antigen presenting cell, it stimulates T-cells into activating B-cells. Macrophage: Macrophage is a “big eater” its main purpose is to devour foreign cells. T-Cell: A T-cell is a cell that helps fight bacteria and viruses. There are different kinds of T-cells such as helper,suppressor,memory, and cytotoxic T-cells. MHC: MHC stands for Major Histocompatibility Complex, it determines if a cell is normal or abnormal.
