Unit 1 Review

Front

What is the membrane attack complex (MAC)?

Back

A structure formed by complement proteins C5b, C6, C7, C8, and C9 that creates pores in the membranes of target cells, leading to cell lysis.

Front

Which complement proteins are involved in the formation of the MAC?

Back

C5b, C6, C7, C8, C9.

Front

What is the primary role of IL-4 in the immune response?

Back

Stimulates B-cell proliferation and promotes Th2 differentiation.

Front

Which cytokine is primarily responsible for neutrophil recruitment?

Back

IL-17.

Front

What is required for B cells to produce plasma cells?

Back

Activation by T helper cells.

Front

What does immunology study?

Back

The immune system's reactions to antigens.

Front

Define cytokines.

Back

Signaling proteins that mediate and regulate immunity, inflammation, and hematopoiesis.

Front

What is the function of T helper cells in the immune response?

Back

They assist in the activation of B cells and cytotoxic T cells.

Front

What is the role of IL-6 in the immune system?

Back

It is involved in inflammation and the acute phase response.

Front

What is the significance of antigen-presenting cells (APCs)?

Back

APCs process and present antigens to T cells, initiating the adaptive immune response.
