Antibody class switching is a biological process in which B cells change the type of antibody they produce without altering the specificity for the antigen. This occurs after initial exposure to an antigen and involves the rearrangement of the constant region of the antibody gene, allowing the B cell to produce different classes of antibodies, such as IgM to IgG or IgA. Class switching enhances the immune response by enabling antibodies to perform various functions more effectively, tailored to different types of pathogens. This process is crucial for adaptive immunity, providing long-lasting protection against infections.
What else can I help you with?
Antibody molecules consists of how many polypeptide chains depending on which class of antibody is considered?
two
What class of antibody forms a large complex that can agglutinate cells?
IgM
Which class of antibody accounts for the bulk of circulating antibody?
IgG antibodies account for the bulk of circulating antibodies in the blood. They are the most abundant class of antibodies and play a crucial role in providing long-term immunity.
What is the class of antibody first secreted in response to a new antigen?
IgM is the class of antibody first secreted in response to a new antigen. It is produced during the initial immune response and helps to activate other components of the immune system.
What antibody class is most abundant in plasma is important in fixing complement and crosses the placenta to provide protection to a newborn?
The antibody class that is most abundant in plasma and is crucial for fixing complement is Immunoglobulin G (IgG). It is also the only antibody class that can cross the placenta, providing passive immunity to the newborn. This transfer of IgG helps protect the infant from infections during the early months of life.
Which class of switching office serves local end-users in a US telephone network?
class 5
Which type of switching office is a primary toll center?
A class 3 office
Which antibody class neutralizes viruses in the intestinal tract?
I would assume IgA class antibodies. The intestinal tract is lined with mucous membranes and the IgA class is primarily secreted through mucous.
What class of antibody is produced in the primary immune response?
The class of immunoglobulin that is produced in the primary immune response is Immmunoglobulin M (IgM). On secondary exposure, the class that predominates would be Immunoglobulin G (IgG).
Which class of antibody produced by a pregnant woman may attack RBCs in her fetus resulting in erythroblastosis fetalis?
IgG molecules.
Is glycoprotein an antigen or antibody?
Antibody
In the primary response to an antigen the first class of antibody to be secreted is?
The class of immunoglobulin to respond to the fist exposure of an antigen is immunoglobulin class M (IgM). While Immunoglobulin G (IgG) would predominate on the second exposure.
