Charles University in Prague Faculty of Science Department of Biochemistry Studies of NK cell receptors and other proteins using recombinant expressions and mass spectrometry Summary of Ph. D. Thesis Daniel Kavan Supervisor: Prof. RNDr. Karel Bezouška, DSc. Prague 2010 Daniel Kavan Introduction Introduction NK cells and CD69 as one of their surface receptors Natural killer cells (NK cells) are the subpopulation of large granular lymfocytes, which lacks the surface receptors typical for B cells or T cells. They are characterized by the presence of NKp46 and NKp30 [Moretta L. et. al. 2002], however. They were named natural killers according to their function in the organism, as they do not need any activation and nevertheless they are able to eliminate abnormal (i. e. infected or transformed) cells from the tissue [Kiessling R. et. al. 1975]. This function is dependent on scanning the major histocompatibility complex (MHC) class I molecules of ambient cells. The resulting action (killing or not killing the target cell) is dependent on the balance of activating and inhibiting signals mediated by the NK cell surface receptors and forwarded to the specific signaling pathway [Raulet D. H. et. al. 2001]. Specificity of NK cells is not based only on one type of antigen receptor as it is in case of T and B cells,...
