CD3CD56NKT-like cells are a rare population of lymphocytes that serve important roles in various types of immune-related diseases, and particularly in cancer. The complement system regulates inflammatory and immune responses by interacting with complement receptors expressed on a range of immune cells. However, whether CD3CD56NKT-like cells are regulated by the complement system has still not been definitively determined.

Here, we show that CR3 is an important negative regulator of NK cell function, which has negative impact on tumor surveillance. Mice deficient in CR3 (CD11b mice) exhibited a more activated NK phenotype and had enhanced NK-dependent tumor killing.

However, the prognostic value of CXCR4 in ovarian cancer remains controversial and has not been emphasized. The aim of this study is to evaluate the prognostic significance of CXCR4 in ovarian cancer by performing a meta-analysis.
