Types of Antigen

What are the 4 Types of Antigens?

The four types of antigens are exogenous, endogenous, autoantigens, and special antigens like alloantigens and xenoantigens.

What are the Different Types of Antigen Cells?

The different types of antigen-presenting cells include dendritic cells, macrophages, and B-cells.

What is Called Antigen?

Antigens also known as immunogens are substances or toxins in your blood which stimulate your immune system to fight them.

How Many Antigens Are There?

The number of antigens is vast and varies depending on the diversity of pathogens and foreign substances encountered by the immune system.

What is Immunization?

Immunization is the process of stimulating the immune system to develop protection against specific diseases, through vaccination.

What are the Different Types of Immunity?

Different types of immunity include innate immunity, which provides immediate defense against pathogens, and adaptive immunity, which involves a specific response tailored to each pathogen.

What is the Structure and Properties of Antigens?

Antigens possess diverse structures and properties, ranging from proteins, polysaccharides, lipids, to nucleic acids, and can produce specific immune responses.

Antigens are substances that the immune system recognizes as foreign and can trigger an immune response. They can be proteins, peptides, polysaccharides, or other macromolecules. Types of antigens include self-antigens, which are recognized by the immune system as belonging to the body, and non-self antigens, such as those from pathogens or foreign substances.

Antigens are important for the immune system’s ability to distinguish between self and non-self, initiating immune responses to protect the body from harmful invaders. In this article, we will study the antigen, its types, and its functions in detail.
