[Research Progress on Biological Properties of Natural Killer Cells and Their Application in B Cell Lymphoma--Review].

B cell lymphoma is a group of very heterogeneous biologically complex malignancies, which originates from lymph nodes with different kinds of clinical and biologic characteristics. B cell lyphoma can occur in every part of body, and accouting for more than 80% of cell lyphomas. Natural killer (NK) is the impartant composition cell of immune system, which can fast response to the targeting cells, such as tumour cells or cells infected by virus without sensitization, NK cells play an important role in the early innate immunity. Compelling evidences shows that NK cells play an important role in occurrence, development and treatment of B cell lyphoma, and B cell lymphoma can be inhibitied by advanced and impoved NK cells. In this review, the biologic characteristics and role of NK cells in B cell lyphoma was summrized briefly.
