T-lymphocyte. Coloured Transmission Electron Micrograph (TEM) of a section through a T-lympho- cyte white blood cell. At centre,the large nucleus is seen (yellow & purple). Cytoplasm is green and cell organelles are yellow. T- lymphocytes are cells of the human immune system,produced in bone marrow and which mature in the thymus gland. This cell type is susceptible to infection by the Human Immunodeficiency Virus (HIV),the causative agent of AIDS. There are three major types of white blood cells: granulocytes,lymphocytes and monocytes,which protect the body against invasion by foreign substances. Magnification: x9,600 at 6x7cm size | |
