  5. 4. Directed Migration of Natural Killer Cells by Microcontact Printing

    University essay from KTH/Tillämpad fysik

    Author : Karl Olofsson; Gustav Stenbom; [2014]
    Keywords : ;

    Abstract : NK cells are large granular lymphocytes that patrol the body for defect or virally infected cells. The migration of natural killer (NK) cells is critical for the detection and elimination of aberrant cells such as tumor- and virally infected cells. If a NK cell stumbles upon a target, i.e. READ MORE
