Document Summary
Readings(testable on final: review the cell-cycle, cell function and immunity. Cell proliferation: cells multiply, grow, regulation of how many cells we have in the body. Cell differentiation: when a cell completes cell cycle and is ready to do what is designed for. Normal immune response: normally, an intact immune system has the ability to combat cancer cells in several ways. Usually, the immune sys-tem recognizes as foreign certain antigens on the cell membranes of many cancer cells. These antigens are known as tumour- associated antigens (also called tumour cell antigens) and are capable of stimulating both cellular and humoural immune responses. Along with the macrophages, t lymphocytes, the soldiers of the cellular immune response, are responsible for recognizing tumour-associated antigens. When t lymphocytes recognize tumour antigens, other t lymphocytes that are toxic to the tumour cells are stimulated. These lymphocytes proliferate and are released into the circulation. Other lymphokines can mobilize other cells, such as macrophages, that disrupt cancer cells.
