Immunology and Antibody Structure Quiz

B cells are responsible for producing antibodies in the immune system.

Cross-linking is the term for the process where antibodies bind to multiple identical epitopes on a single antigen.

IgA is associated with mucosal immunity and found in secretions like tears and saliva.

In the context of antibodies, the Fab region is the unique region that determines antigen specificity within the variable region.

IgM is typically the first antibody to be produced during an immune response and is important for mucosal immunity.

Antibodies primarily function by neutralizing pathogens in the immune system.

IgG is the most abundant immunoglobulin class in human serum.

Memory B cells provide long-term immunity in the immune system.

IgG antibodies can cross the placenta and provide passive immunity to the fetus.

Type I hypersensitivity reaction involves IgE antibodies and mast cells.

The main function of cytotoxic T cells in the immune response is to destroy infected cells.

Opsonization is the process by which antibodies bind to antigens, marking them for destruction.

The variable region of the antibody molecule determines its specificity for antigens.

T-cell maturation refers to the process by which lymphocytes mature and differentiate in the thymus gland.

Interleukin-2 (IL-2) is crucial for the activation and proliferation of T cells during an immune response.

The classical pathway of the complement system is activated by antibodies binding to antigens.

Autoimmunity is the term for the phenomenon where an individual's immune system attacks its own cells and tissues.
