<prompt> A laboratory analysis report of a specific fraction of a patients lymphocytes the following:HLA, Band C,PHA, CD3-, CD16, CD11a CD18, CD56, and in vitro blastogenesis with IL12 What are the lymphocytes this set describes?B lymphocytesCytotoxic T lymphocytesNatural killer cellsT helper 1 subset  <response>: NK cells do not express a cell surface TCRlCD3 complex and are CD4-. About half of human NK cells are CD8. Also, most NK cells express an Fe IgG receptor, known as CDI6, and CD56, a neural cell adhesion molecule variant. NK cells are generally CD16, CD56, and CD3-, which contrasts them with I cells which are CD3, CDl6-, and CD56
