Coloured scanning electron micrograph of a normal T-lymphocyte,a type of white blood cell. Characteristic of normal T-lymphocytes are the long microvilli projecting from the cell surface. T-lymphocytes are susceptible to infection by the Human Immunodeficiency Virus (HIV),the causative agent of Acquired Immune Deficiency Syndrome (AIDS). There are three major types of white blood cells: granulocytes,lymphocytes and monocytes. Together they protect the body against the invasion of foreign substances and participate in antibody production. Magnification: x2750 at 6x6cm,x1,530 at 35mm size | |
