What type of protein are antibody molecules made

Plasma cell, short-lived antibody-producing cell derived from a type of leukocyte (white blood cell) called a B cell. B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell. Once released into the blood and lymph, these.

An epitope (also known as an antigenic determinant) is part of an antigen that is recognized by the immune system, specifically by antibodies and B and T cells. Other immune cells like APCs cannot recognize epitopes (only PAMPS and DAMPS).

IgM is the first type of antibody produced postnatally. IgG antibodies to protein antigens are formed in early infancy, but IgG antibodies to polysaccharides do not appear until 2–2.5 years of age.An antigen that induces an immune response—i.e., stimulates the lymphocytes to produce antibody or to attack the antigen directly—is called an immunogen. On the surface of antigens are regions, called antigenic determinants, that fit and bind to receptor molecules of complementary structure on the surface of the lymphocytes.As discussed in Chapter 12, newly synthesized proteins enter the biosynthetic- secretory pathway in the ER by crossing the ER membrane from the cytosol. During their subsequent transport, from the ER to the Golgi apparatus and from the Golgi apparatus to the cell surface and elsewhere, these proteins pass through a series of compartments, where they are successively modified.Discuss antibody production.
