Exam 34: Adaptive Immunity

A type of antibody light chain is the ___________ chain.

Class I and II MHC molecules

Class I major histocompatibility complex molecules are found on ____________ cells.

During activation of a T cell,the cytokine it produces to stimulate its own proliferation is

The secondary immune response is typically stronger than the primary response because __________ during the secondary response.

The variable domain of antibody molecules

T cells produce and secrete factors which do not directly interact with invading microorganisms but which augment the body's defense mechanisms.These molecules are called

Which type(s)of antigen-presenting cell can activate T cells?

Cytotoxic T cells destroy target cells by

Tumor cells of the immune system that produce large quantities of antibodies and can be readily cultivated are called

T cells attack

Antigens that depend on the function of T-helper cells are called __________ antigens.

Superantigens cause

Class II major histocompatibility complex molecules are found on all of the following types of cells except

Matching 1)IgG 2)IgD 3)IgM 4)IgA A.Accounts for about 10% of the immunoglobulin pool. B.The major immunoglobulin in human serum. C.Has special features associated with secretory mucosal surfaces. D.Found in trace amounts in the serum.

Each antigen has one antigenic determinant site or epitope.

When a presented antigen fragment interacts with the T cell receptor of a helper T cell,the co-receptor that must also participate to finalize recognition is

T cells are so named because they mature in the thyroid.

If the clonal selection theory is correct,there exists at least one lymphocyte capable of synthesizing an antibody specific to each antigen prior to exposure to the antigen.

In an antibody molecule,the __________ region mediates binding to host cells.
