- What's the difference between antigen and pathogen?
Answer Quick, skin, destroys blocks reduces Skin, macrophages, goblet cells
Answer Antigens are part of the immune system that ID pathogens and mark them for future identification
- Who is the first to arrive on scene to deal with the pathogen?
Answer macrophages
- What is Antigen Presenting Cell? Name 2 example of APC. What do they do?
Answer These specialized populations initiate adaptive immune responses by presenting antigens captured from the environment to B and T lymphocytes.
- What is the process of activating T-cells and B-cells, and making replica- tion of the T-
cells and B-cells?
Answer During T cell-dependent activation, B cells absorb the antigen and then present pieces of the antigen on their surface via a major histocompatibility complex (MHC). Helper T cells can then recognize those antigens via the MHC and activate the B cells.
- What is the name of activated B-cell?
Answer Once B-cells are activated, they become plasma cells that produce antibodies in response to an antigen. Or they become memory cells that remember the antigen so your immune system can quickly identify and fight it in the future. 1 / 2
