Exam 2: Overview of the Immune System

Which molecules on the cell surfaces of transplanted tissue are most important to match to the recipient to immediately prevent the recipient's T cells from recognizing the transplanted tissue as foreign?

In an inflammatory reaction, increased vascular permeability causes escape of the fluid into the tissues resulting in ________.

If a naive T cell does not encounter its corresponding antigen within a few days, what happens?

Each of the following is one of the four basic characteristics of inflamed tissue except

A mature T helper cell should possess CD2, CD3, and CD4.

When the immune system initiates an inflammatory response, this is always beneficial to resolving the injury or infection.

Microbes and/or their products (endotoxins and lipopolysaccharides)are the underlying cause of all inflammations.

When an antibody is bound to an antigen, which complement path(s)is (are)activated?

Which immunoglobulin subclass below resides exclusively on the surface of B cells and serves a regulatory function?

What is the exact structure to which an antibody or T cell receptor will bind?

Why do phagocytes dramatically increase metabolic rate and oxygen consumption when they begin phagocytosis?

Specialized antigen- presenting cells such as macrophages, dendritic cells, and B cells are the only cells to possess class II MHC antigens, while almost all of the remaining nucleated cells in the body possess class I MHC antigens.

The positive acute phase reactant responsible for binding and inactivating certain drugs is alpha- 1 acid glycoprotein.

The two cell types that are capable of attacking host cells that are infected with virus are________ and ________.

The digestive enzymes of phagocytic cells are contained in the

Which cell type(s)below are associated with lysis of tumor cells?

Which of the following is characteristic of the primary immune response (first encounter with an antigen)as compared with the secondary immune response (later encounter with the same antigen)?

The process by which certain substances function to attract leukocytes to an tissue where they're needed is called ________.

How does a T cytotoxic lymphocyte recognize that a host cell is infected with a virus?

Which cell(s)below is (are)capable of immunologic memory?
