Immune system and Lymphoid organs
Cards (69)
- First line of defense of an intruding pathogen?
- An antigen-indpendent?
- specific?
- non-specific?
- An antigen-dependent?
- Used by the host immediately or within hours of encountering an antigen?
- Develops more slowly and is based on antigen presentation to lymphocytes?
- Acquired gradually by exposure to microorganism?
- Include physical barriers such as the skin and mucuous membranes?
- Involves leukocytes and proteins?
- Short cationic polypetides?
- Hydrolyzes bacterial cell wall components?
- Kill bacteria by distrupting cell wall?
- A system of proteins in blood plasma, mucus and macrophages?
- React with bacterial surface components to aid for removal of bacteria?
- Paracrine factors from leukocytes and virus infected cells that signals NK cells?
- Response in B and T lymphocytes?
- Recognized by lymphocytes to elicit specific immune response against them?
- Immunoglobulins produced by plasma cells after a progenitor B cell is activated by specific antigen?
- Cell surface glycoproteins whose primary function is to present peptide fragments for recognition T cells lymphocyte?
- Founds on surfaces of all nucleated cells bear fragments of their constituents protein?
- Only antigen-presenting cells?
- Antibodies are primarily responsible for the response?
- B cell lymphocyte is a principally responsible for this method?
- Mature T lymphocyte, macrophages and cytokines are the main drivers here?
- The stem cell for all lymphocyte are located in?
- Where is the Maturation of lymphoid organ occurs?
- Where is the activation of lymphoid organs and became functional?
- Bilobed organ in the mediastinum?
- Most active and prominent before puberty and undergoes involution with less activity on adult?
- Primary organ where T cell is produced?
- Originates from endoderm?
- Darkyl basophilic?
- Contains extensive population of T lymphoblast?
- Blood-thymus barrier that is responsible in preventing unregulated exposure of thymocyte to the antigens?
