- 6. The enzyme defect __________ leads to the accumulation of toxic purine nucleosides and nucleotides, resulting in the death of most developing lymphocytes within the thymus. It is a cause of severe combined immunodeficiency.
- 7. in adaptive immunity there are cells that aid in the response but do not directly mediate specific antigen recognition. They include phagocytes, mast cells, and NK cells.
- 8. The removal of antibodies specific for one antigen from an antiserum to render it specific for another antigen or antigens is called
- 9. any substance that enhances the immune response to an antigen with which it is mixed.
- 11. These are mucosal-associated lymphoid tissues located in the nasal cavity.
Down
- 1. this is is a rare genetic disorder characterized by the absence or severely reduced levels of mature B cells and immunoglobulins (antibodies) in the blood.
- 2. The acquired immune deficiency syndrome AIDS is a disease caused by infection with the human immunodeficiency virus (HIV-1). AIDS occurs when an infected patient has lost most of his or her ______ so that infections with opportunistic pathogens occur.
- 3. Immunization with antigen is called active immunization to distinguish it from the transfer of antibody to an unimmunized individual, which is called
- 4. _____is the response of antigen-specific lymphocytes to antigen, including the development of immunological memory
- 5. _____is a highly aggressive, undifferentiated form of lymphoid malignancy derived from a progenitor cell that is thought to be able to give rise to both T and B lineages of lymphoid cells. Most of these leukemias show partial differentiation toward the B-cell lineage (so called B-ALL) whereas a minority show features of T cells (T-ALL).
- 8. _____proteins are key linkers between receptors and downstream members of signaling pathways. These proteins are functionally heterogeneous, but all use a similar domain, known as an SH2 domain
- 10. _____immunity is immunity conferred on a naive or irradiated recipient by transfer of lymphoid cells from an actively immunized donor. This is called adoptive transfer
