IG SWITCH SEQUENCE Meaning and
Definition
-
Ig Switch Sequence refers to an important series of events that occur within the immune system in response to an antigenic stimulus. This sequence specifically pertains to the class switching process of immunoglobulins (Igs), which are essential proteins involved in humoral immune responses.
When a B cell encounters an antigen, it undergoes a complex set of genetic rearrangements known as V(D)J recombination to produce an Ig molecule with a specific antigen-binding site. Initially, this process produces IgM. However, under certain conditions, B cells can undergo the Ig Switch Sequence to change the type of Ig they produce, leading to the generation of other Ig classes such as IgG, IgE, or IgA.
The Ig Switch Sequence involves a molecular mechanism known as class switch recombination (CSR), which occurs at the DNA level. It involves the deletion of intervening DNA between specific gene segments for each Ig class and the subsequent joining of the expressed antigen-binding regions to a new constant region gene segment. This recombination process is catalyzed by specific enzymes and regulatory factors that mediate the switch from IgM production to other Ig classes.
The Ig Switch Sequence plays a crucial role in the adaptability and diversity of the immune response. By changing the isotype of the Ig molecule, B cells can alter the functional properties of the antibody produced, such as its ability to cross cell barriers, activate complement, or bind to specific cell surface receptors. This process allows for the effective targeting of different types of pathogens or foreign substances while enhancing immune defense and resolution of infections or diseases.
