Color-enhanced Scanning Electron Micrograph (SEM) of two T-lymphocytes, a type of white blood cell involved in the stimulation (Helper T-cells) and regulation (Suppresser T-cells) of immune response. Cytotoxic T-cells (Killer T-cells) target virus invaded cells and cancer cells, destroying them by lysis. Characteristic of 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 AIDS. Magnification 1300x at 35mm.
