免疫名词解释历年题
1. Recirculation of lymphocytes(淋巴细胞再循环)It means the continuous movement of lymphocytes across the sites through out blood and lymphatic vessels, and it is critical for the initiation and effector phases of immune response.
2. hapten(半抗原) antigen which can combine with the corresponding Ab or sensitized T lymphocyte but can not evoke the immune response independently.
3. TD-Ag(thymus dependent Ag) Ag stimulates B cells to produce Ab with the help of T cells and macrophage.
4. TI-Ag(thymus independent Ag)Ag stimulates B cells to produce Ab without the help of T cells and macrophage.
5. heterophile Ag(异嗜性抗原)common antigens shared by different species and play an important role in immunopathology and diagnosis.
6. HVR(hypervariable region)超变区Most of sequence differences among antibodies are confined to three short stretches in the V regions of heavy and light chains are called HVR
7. CDR(complementary determinant region)互补决定区The sequences of the antibodies form an antigen binding surface that is complementary to the three dimensional structure of the bound antigen It is also called complementary determinant regions.
8. idiotype (独特型) Igs produced by each B cells clone possessing unique structure respectively in HVR or CDR, the unique structure is called idiotype of Ig.
9. monoclonal Ab (mAb 单克隆抗体) It is prepared by hybridoma technique. Immunized spleen cells (B cells) fuse with myeloma cells and form hybridoma with property of proliferating Ab
10. conformational determinants 构象决定簇They are composed of amino acid residues are not in a sequence but become special juxtaposed in folded protein. They are usually on the surface of antigen and be recognized by B cells and Ab.
11. ADCC（antibody dependent cell mediated cytotoxicity）It is a process in which NK cells are target to Ab coated cells, resulting in lyses Ab coated cells .FcRⅢ is expressed on NK cell membrane and mediate binding of IgG.
12. MAC membrane attack complex 攻膜复合体A lytic complex of the terminal components of complement cascade, Including C5678and multicopies of C9,which forms in the membrane of target cells MAC causes lethal ionic and osmotic changes in cells.
13. CK cytokine 细胞因子A group of low molecular weight polypeptides or proteins which are secreted by activated immunocytes or some matrix cells and possess high activity and various functions. Their major functions are to mediate and regulation immune response and inflammation reaction.
14. CAM or AM cell adhesion molecules 黏附分子The cell surface molecules whose function is to promote adhesive interaction with other cells or the extra cellular matrix and play a crucial role in cell interaction, recognition, activation and migration.
15. CD cluster of differentiation 分化簇It is a group of cell surface molecules associated with the development and differentiation of immune cells.
16. MHC major histocompatibility complex主要组织相容性复合体It is a group of genes which encode for major histocompatibility antigens and relate to immune response.
17. HLA human leukocyte antigen 人类白细胞抗原The major histocompatibility antigens for human bodies which associated with histocompatibility and immune response.
18. HLA complex The MHC of human, a cluster of genes which encode for HLA and related to histocompatibility and immune response.
19. MHC restriction In interaction of T cell and APC or target cells, T cells not only recognize specific antigen but also recognize polymorphic residules of MHC molecules.
20. PAMP(pathogen associated molecular pattern) 病原相关分子模式distinct structures or components that are common for many pathogens ，such as LPS, dsRNA of viruses etc.
21. PRR (pattern recognition receptor) The receptors that can recognize PAMP, located on the surface of macrophage, including mannose receptor, scavenger receptor , toll like receptor etc.
22. APC a group of cells which can uptake and process antigen and present antigen-MHC-Ⅰ/Ⅱ complex to T cells, playing an important role in i
