Research Interest

The long-term goal of our laboratory is to illuminate the function of immune surface molecules and to open up a new research field at the interface of cancer, immunology, and stem cell research. We are also actively developing novel therapies for cancer treatment.

1) The function of ITIM receptors in cancer and hematopoietic stem cells. The leukocyte Ig-like receptor subfamily B (LILRB) is a group of type I transmembrane glycoproteins with extracellular Ig-like domains and intracellular ITIMs (immunoreceptor tyrosine-based inhibitory motifs). This group of receptors contains five members, LILRB1 to LILRB5. LILRB 1-5 transduce signals via ITIMs that recruit phosphatase SHP-1, SHP-2, or SHIP, leading to negative regulation of immune cell activation. The activation of LILRBs on immune cells by their ligands may contribute to immune evasion by tumors. We cloned LILRB2 as a receptor for the “orphan ligand” Angptl2, revealing unexpected function of classical immune inhibitory receptors in maintenance of stemness of hematopoeitic stem cells (HSCs). Subsequently we demonstrated that several members of LILRB family are expressed by tumor cells, including certain hematopoietic and solid cancer cells, and may directly regulate cancer development and relapse as well as the activity of cancer stem cells. We further elucidated unique signaling downstream of a representative ITIM-containing receptor in leukemia cells. LILRBs thus have dual concordant roles in tumor biology – as immune checkpoint molecules and as tumor-sustaining factors. Importantly, the study of knockout mice indicated that LILRBs do not affect hematopoiesis and normal development. Therefore LILRBs may represent ideal targets for tumor treatment. Targeting LILRBs may perfectly combine immunotherapy and targeted therapy, and lead to the development of novel therapies for cancer treatment.

2) Angiopoietin-like proteins and receptors. In addition to LILRB2, we are identifying additional receptors for various angiopoietin-like proteins. We are studying the function of these ligands and receptors in cancer, stem cells, and immunity.

3) The role of PD-L1 in hematopoietic stem cells (HSCs). We demonstrated that the immune privilege of HSCs can be regulated by controlling surface expression of the immune inhibitor PD-L1, and ex vivo expanded HSCs efficiently overcome MHC barrier and engraft allogeneic recipient mice.

4) The opposite effects of fasting on different types of cancer. How dietary restrictions affect hematopoietic malignancies are unknown. We showed that fasting alone robustly inhibits initiation and reverses later development of acute lymphoblastic leukemia (both B-ALL and T-ALL) but not acute myeloid leukemia (AML). Fasting blocks ALL development by upregulation of leptin receptor (LepR) and its downstream signaling through Prdm1. Our results indicate that the effects of fasting on tumor growth are cancer-type dependent, and suggest new avenues for development of novel strategies for leukemia treatment.
