Antigen is usually a 'Foreign' protein, usually a microorganism enered in body. It iduces two types of response 1) Cell mediated. 2) Humeral or antibody response. It starts getting produced by 'B' cell in bone marrow. It starts appearing after about 2 weeks of challenge. It give a pick response between 1 to 2 months. It can be inhanced by reapeated challenge during this period. Third challenge or vaccine given at 6 to 9 months, respectively, gives enhanced antibody response. These antibodies are very specific in nature that it will neutralise that perticular protein only. It make the protein inactive. There by protecting body from that perticular protein.

How igm play impoartant role in immunity?
IgM is the first antibody produced during an immune response, providing quick and early defense against pathogens. It is primarily involved in neutralizing pathogens and activating the immune system's responses. IgM also plays a critical role in initiating the adaptive immune response by helping to recognize and clear infections.
What is a isotype?
An isotype is a variant form of an antibody that contains the same antigen-binding site but differs in the constant region, influencing its function and role in the immune response. Isotypes are designated by letters (e.g., IgG, IgM) and play a crucial role in diverse immune functions, including opsonization, complement activation, and immune response modulation.
Why do all molecules which have the property of antigenicity do not have the property of immunogenicity?
Antigenicity refers to the ability to specifically bind to an antigen receptor on the immune cells, while immunogenicity involves triggering an immune response. Not all molecules that can bind to the receptor are capable of initiating a strong enough response to be considered immunogenic. Factors such as size, complexity, and the presence of specific epitopes play a role in determining immunogenicity.
What cells suppress the immune response in order to prevent over activity?
Regulatory T cells (Tregs) are a type of immune cell that suppress the immune response to prevent overactivity. They play a crucial role in maintaining immune tolerance and preventing autoimmunity by controlling and regulating the activity of other immune cells.
What role do mast cells play in the immune response?
Mast cells are important in the immune response as they release histamine and other inflammatory mediators in response to allergens and pathogens. This triggers inflammation and helps recruit other immune cells to the site of infection. Overactive mast cell activity can lead to allergic reactions and asthma.

What is the relationship between heavy chain, light chain, and antibody in the context of immune response?
In the context of the immune response, antibodies are made up of heavy and light chains. These chains come together to form the structure of the antibody, which plays a key role in recognizing and neutralizing harmful substances in the body. The heavy chain provides stability and structure to the antibody, while the light chain helps in binding to specific antigens. Together, the heavy and light chains work in harmony to create a functional antibody that can target and eliminate foreign invaders in the immune response.
What is antibody mediated response?
Antibody-mediated response, also known as humoral immunity, is a crucial aspect of the adaptive immune system where B cells produce antibodies in response to specific antigens. These antibodies bind to pathogens such as bacteria and viruses, neutralizing them or marking them for destruction by other immune cells. This response is essential for providing long-lasting immunity and is the basis for the effectiveness of many vaccines. It plays a vital role in protecting the body against infections and diseases.
What essential role do antibodies play in the adaptive immune system and how do they contribute to immune response?
Antibodies are proteins produced by the immune system that help identify and neutralize harmful pathogens like viruses and bacteria. They play a crucial role in the adaptive immune response by recognizing specific antigens on these pathogens and marking them for destruction by other immune cells. This targeted response helps the body fight off infections more effectively.
What is the largest antibody produced by the fetus?
The largest antibody produced by the fetus is Immunoglobulin M (IgM). It is the first antibody to be produced in response to an infection and plays a crucial role in the fetal immune response. IgM is typically produced by the fetus around the 20th week of gestation and is important for detecting and neutralizing pathogens. Unlike other antibody classes, IgM is pentameric in structure, allowing it to effectively bind to multiple antigens.
Why do all molecules which have the property of antigenicity do not have the property of immunogenicity?
Antigenicity refers to the ability to specifically bind to an antigen receptor on the immune cells, while immunogenicity involves triggering an immune response. Not all molecules that can bind to the receptor are capable of initiating a strong enough response to be considered immunogenic. Factors such as size, complexity, and the presence of specific epitopes play a role in determining immunogenicity.
What is antigen short for?
Antigen is short for "antibody generator." It refers to any substance that can provoke an immune response in the body, typically by being recognized as foreign. Antigens can be proteins, polysaccharides, or other molecules found on the surface of pathogens like bacteria and viruses, as well as on non-pathogenic substances. They play a crucial role in the immune system's ability to identify and combat infections.
How are regulatory T cells activated and what role do they play in the immune response?
Regulatory T cells are activated by recognizing specific antigens presented by other immune cells. Once activated, they suppress excessive immune responses to prevent autoimmunity and maintain immune tolerance. They play a crucial role in controlling inflammation and preventing immune reactions against self-tissues.
