Effector Functions of Antibodies Essay - 919 Words.

Antibody Effector Functions. Antibodies act by a number of mechanisms, most of which engage other arms of the immune system. Antibodies can simply block interactions of molecules or they can activate the classical complement pathway (known as complement dependent cytotoxicity or CDC) by interaction of C1q on the C1 complex with clustered antibodies.

Antibodies, also known as immunoglobulins, are Y-shaped proteins that are produced by the immune system to help stop intruders from harming the body. When an intruder enters the body, the immune.

The primary function of antibodies is to bind antigen. B cells initially produce only membrane-bound Ig serving as receptors on B cells that mediate the antigen-triggered activation of B lymphocytes.

The stem of the Y-shaped antibody monomer is called the F c region, so named because when antibody structure was first being identified, it was a fragment (F) that crystallized (c) in cold storage. Characteristics and Functions of Immunoglobulin’s (Igs) or Antibodies: Antibodies show the following characteristics and perform different functions.

Immunoglobulins, also known as antibodies, are glycoprotein molecules produced by plasma cells (white blood cells). They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction.

The increasing knowledge on the Fc-mediated effector functions of antibodies drives the development of better therapeutic antibodies for cancer immunotherapy or treatment of autoimmune diseases.

Antibodies can also induce the innate immune response to destroy a pathogen, by activating phagocytes such as macrophages or neutrophils, which are attracted to antibody-bound cells. Affinity describes how strongly a single antibody binds a given antigen, while avidity describes the binding of a multimeric antibody to multiple antigens.

This is achieved through a wide range of effector functions that may be activated by immune complexes. Antibodies can bind soluble antigen present in the blood or extra-cellular fluids, this property is particularly helpful if the antibody blocks the molecular docking mechanism that allows toxins, viruses and some bacteria to gain access to cells.

Since effector function relies on the amino acid sequences in the Fc region, hence some of the functions they provide are class specific. In total, there are 4 main effector functions of antibodies: neutralization of microorganisms and toxins, antibody-mediated opsonisation and phagocytosis of microorganisms, antibody-dependent cell cytotoxicity and activation of complement pathway.
