IL-1R8 is a checkpoint in NK cells regulating anti-tumor and anti-viral activity

Project description:We reported that IL-1R8 serves as a checkpoint for NK cell maturation and effector functions. Its genetic blockade unleashes NK-cell mediated resistance to hepatic carcinogenesis, hematogenous liver and lung metastasis and cytomegalovirus infection.

IL-1R8 is a checkpoint in NK cells regulating anti-tumour and anti-viral activity.

Project description:Interleukin-1 receptor 8 (IL-1R8, also known as single immunoglobulin IL-1R-related receptor, SIGIRR, or TIR8) is a member of the IL-1 receptor (ILR) family with distinct structural and functional characteristics, acting as a negative regulator of ILR and Toll-like receptor (TLR) downstream signalling pathways and inflammation. Natural killer (NK) cells are innate lymphoid cells which mediate resistance against pathogens and contribute to the activation and orientation of adaptive immune responses. NK cells mediate resistance against haematopoietic neoplasms but are generally considered to play a minor role in solid tumour carcinogenesis. Here we report that IL-1R8 serves as a checkpoint for NK cell maturation and effector function. Its genetic blockade unleashes NK-cell-mediated resistance to hepatic carcinogenesis, haematogenous liver and lung metastasis, and cytomegalovirus infection.

The RNA m6A reader YTHDF2 controls NK cell anti-tumor and anti-viral immunity

Project description:N6-methyladenosine (m6A) is the most prevalent post-transcriptional modification on RNA. NK cells are the predominant innate lymphoid cells that mediate anti-viral and anti-tumor immunity. However, whether and how m6A modifications affect NK cell immunity remains unknown. Here, we discover that YTHDF2, a well-known m6A reader, is upregulated in NK cells upon activation by cytokines, tumors, and cytomegalovirus infection. Ythdf2 deficiency in NK cells impairs NK cell anti-tumor and anti-viral activity in vivo. YTHDF2 maintains NK cell homeostasis and terminal maturation, correlating with modulating NK cell trafficking and regulating Eomes, respectively. YTHDF2 promotes NK cell effector function and is required for IL-15-mediated NK cell survival and proliferation by forming a STAT5-YTHDF2 positive feedback loop. Transcriptome-wide screening identifies Tardbp to be involved in cell proliferation or survival as a YTHDF2-binding target in NK cells. Collectively, we elucidate the biological roles of m6A modifications in NK cells and highlight a new direction to harness NK cell anti-tumor immunity.

Effect of anti-IL-15 administration on T cell and NK cell homeostasis in rhesus macaques (TCM)

Project description:Analysis of the effect of anti-IL-15 monoclonal antibody treatment on T cell and NK cell homeostasis in rhesus macaques. The hypothesis tested in the present study was that repeated administrations of a rhesusized anti-IL-15 monoclonal antibody would block IL-15 activity in vivo and result in changes to T and/or NK cell population dynamics that would reflect physiologic IL-15 function. The results provide important information on the specific role IL-15 plays in effector memory T cell and NK cell homeostasis, noting that effector memory T cells but not NK cells can be maintained in the absence of IL-15 signaling by the activity of other cytokines. Sort-purified CD8+ and CD4+ TCM from PBMC, before and after treatment with IgG1 Ab and anti-IL15 Ab

RNA squencing of human NK cells activated with IL-15 or IL-12, IL-15, and IL-18

Project description:NK cells are an emerging cancer cellular therapy and potent mediators of anti-tumor immunity. Cytokine-induced memory-like (ML) NK cellular therapy is safe and induces remissions in acute myeloid leukemia (AML) patients. However, the dynamic molecular changes that occur after memory-like differentiation in vitro are unclear. Here, control or ML NK cells purified from normal donor PBMC were generated in vitro. Briefly, RosetteSep-purified NK cells were incubated in IL-12, IL-15, and IL-18, or low-dose IL-15 as a control for 16-18 hours. Control or cytokine-activated NK cells were washed three times and cultured for 6 days in low-dose IL-15, which is required for NK cell survival. After 6 days, RNA was isolated from control and memory-like (ML) NK cells (IL12/15/18 activation) and RNA-sequencing performed. Because the transcription factor GATA-3 was increased specifically in ML NK cells, we hypothesized ML NK cells would exhibit a GATA-3 gene signature compared to control NK cells. Indeed, using GSEA, a significant gene signature was associated with ML NK cell differentiation. These data support the role for GATA-3 in regulating the ML NK cell molecular program.
