Exploring The Role Of Nkr-P1b:Clr-B Interaction In Mouse Mammary Tumour Immunosurveillance, Raghd Al Olabi

Electronic Theses and Dissertations

Natural killer (NK) cells are large, granular, and cytotoxic innate lymphocytes which do not require prior antigenic exposure to target cancerous and virally infected cells. NK cells possess activating and inhibitory receptors which may activate or inhibit NK cell activity, respectively. In mice, the inhibitory NKR-P1B receptor on NK cells recognizes the C-type lectin-related protein-b (Clr-b) ligand expressed on most autologous cells but downregulated on many tumour cell lines. In B cell lymphoma models, the disruption of NKR-P1B:Clr-b interaction results in delayed tumour development and progression, suggesting that blockage of inhibitory signals from NKR-P1B augments NK cell activity against lymphoma …
