cell - mediated immunity in a sentence
- The development of cell-mediated immunity correlated with delayed hypersensitivity and an inflammatory response is associated with clinical cure, whereas the lack of or a defective cell-mediated immunity predisposes the host to chronic or recurrent dermatophyte infection.
- In either scenario, there is hypothesized reconstitution of antigen-specific T cell-mediated immunity with activation of the immune system following HIV therapy against persisting antigen, whether present as intact organisms, dead organisms, or debris.
- Through their role in the development of T cell immunologic memory, which depends upon the expansion of the number and function of antigen-selected T cell clones, they also have a key role in enduring cell-mediated immunity.
- A common evolutionary adaptation to this is seen in both intracellular microbes and tumors : the chronic down-regulation of MHC I molecules, which makes affected cells invisible to T cells, allowing them to evade T cell-mediated immunity.
- Th1 cells and their associated cytokines are involved in cell-mediated immunity to intracellular pathogens and delayed-type hypersensitivity reactions, whereas Th2 cells are involved in the control of extracellular helminthic infections and the promotion of atopic and allergic diseases.
- It's difficult to find cell - mediated immunity in a sentence.
- The Th1 response is characterized by the production of Interferon-gamma, which activates the bactericidal activities of macrophages, and induces B cells to make opsonizing ( coating ) and complement-fixing antibodies, and leads to " cell-mediated immunity ".
- By the mid-1960s, immunologists were convinced that there were indeed two separate arms of the immune system : one dealing exclusively with the production of circulating antibodies ( humoral immunity ), and another that is involved in the delayed hypersensitivity-type reactions and graft rejections ( cell-mediated immunity ).
- Cells which are known nowadays to express the protein L1 are : immature oligodendrocytes and Schwann cells, which are non-neuronal cells that provide support and protection for neurons and form myelin; T cells which are lymphocytes involved in cell-mediated immunity; other types of lymphocytes such as B cells and Monocytes.
- A second defense of vertebrates against viruses, cell-mediated immunity, involves immune cells known as T cells : the body's cells constantly display short fragments of their proteins on the cell's surface, and if a T cell recognizes a suspicious viral fragment there, the host cell is destroyed and the virus-specific T-cells proliferate.
