Animal-to-Human Transplants : the ethics of xenotransplantati<strong>on</strong><br />

Virus<br />

A minute infectious organism made of genetic material and protein. It is not<br />

normally c<strong>on</strong>sidered to be a living organism, since it cannot live independently.<br />

Instead, viruses must infect living cells and reproduce inside them. New virus<br />

particles can then leave the cell. In some viruses, such as the herpes viruses, the<br />

genetic material is DNA. In others, such as the HIV virus that causes AIDS, the<br />

genetic material is a different type, called RNA (paragraph 6.9).<br />

White blood cells<br />

White blood cells (leucocytes) are the blood cells that enable the body to mount an<br />

immune resp<strong>on</strong>se. They are divided into two main groups: B-cells and T-cells<br />

(paragraphs 3.9 - 3.14).<br />

of organs, tissue or cells (paragraph 3.8).<br />
