The binding of antibodies to invading pathogens also recruits various types of white blood cells and a system of blood proteins, collectively called complement(discussed in Chapter 25). The simplest type of antibody consists of A. a single folded polypeptide chain. A. T cell B. Cytokine C. B cell D. Erythrocyte 10. The antibody immune response is highly complex and . T lymphocytes are involved in the humoral immunity and the differentiated plasma cells from B lymphocytes secrete specific antibodies for a particular pathogen. Structure: The heavy chains of the IgA antibody are of the Alpha subclass, and it has four antigen binding sites. NK cells are best known for killing virally infected cells, and detecting and controlling (PLAZ-muh sel) A type of immune cell that makes large amounts of a specific antibody. Their . Neutrophils are phagocytes, meaning they surround and engulf invading germs, which are then killed and digested. C. 2 polypeptide chains, one large and one small. et al. However, as cells of the innate immune system, NK cells are classified as group I Innate Lymphocytes (ILCs) and respond quickly to a wide variety of pathological challenges. The part of an antigen binding site on an antibody that binds antigen is the A. idioblast. The various types of white blood cells. Approximately 0.1 percent of all cells in the blood are leukocytes, which encompass monocytes (the precursor of macrophages) and lymphocytes. It is derived from the Greek roots leuk-meaning "white" and cyt . The white blood cell count rises in cases of infection, steroid use and other conditions. In their most mature form, called plasma cells,they are filled with an extensive rough endoplasmic reticulum(Figure 24-7B). Before birth and throughout childhood, the thymus is instrumental in the production and maturation of T-lymphocytes or T cells, a specific type of white blood cell that protects the body from certain threats, including viruses and infections.

Macrophages This is a colored scanning electron micrograph (SEM) of Mycobacterium tuberculosis bacteria (purple) infecting a macrophage. Lymphocytes protect the body against cancerous cells and cells that have become infected by pathogens, such as bacteria and viruses. Once B lymphocytes spot the antigen, they begin to secrete antibodies (antigen is short for "antibody generators"). The two types of lymphocytes of the adaptive immune response are B and T cells (Figure 12.12). Immuno describes immunity and globulin describes protein. In addition to their cell killing function, NK cells secrete a broad range of cytokines and chemokines to modulate the activity of other immune cells. Cytoplasmic granules in eosinophils take up eosin, a histological dye; cytoplasmic granules of basophils stain with a basic, blue dye. 1.
