The functional loss of human natural killer cell activity induced by K562 is reversible via an interleukin-2-dependent mechanism

SI Abrams, Z Brahmi - Cellular immunology, 1986 - Elsevier
In a recent study, we evaluated the functional status of human natural killer (NK) cells after

A novel mechanism for cancer cells to evade immune attack by NK cells: the interaction between NKp44 and proliferating cell nuclear antigen

B Rosental, U Hadad, M Brusilovsky… - …, 2012 - Taylor & Francis
