Natural killer cells (NK cells) are a component of the innate immune system that does not directly attack invading microbes. Rather, NK cells destroy compromised host cells, such as tumor cells or virus-infected cells, recognizing such cells by a condition known as missing self..
These cells 1) usually express CD8, and, 2) destroy infected cells in an antigen-specific manner that is dependent upon the expression of MHC class I molecules on antigen presenting cells. T Suppressor/ T Regulatory Cells: T suppressor cells suppress the T and B cell responses and express CD8 molecules. T Cell Receptor: Structure and Genetic Basis 1. Mature T cells express antigen-specific TCR in a complex with CD3 molecules. The TCR is a disulfide-linked heterodimer composed of either Î±Î² or Î³Î´ chains.
