False-colour transmission electron micrograph of an experimental "HIV-antigen" vaccine for AIDS. The virus-like particles seen here are derived from yeast. They contain antigens specific to the HIV virus. AIDS is an acquired disease of the immune system caused by HIV (Human Immunodeficiency Virus). The harmless virus-like carrier seen here is being tested for its effectiveness in combatting the onset of AIDS. It has been labelled with antigens (proteins) which,it is hoped,will alert the body's immune system to fight the HIV virus. Magnification: x70,000 at 6x4.5cm size | |
