Project description:Studies of chimeric antigen receptor (CAR)-T and -Natural killer (NK) cells have shown promising results in treating hematological malignancies. However, there are still obstacles to effectively treating solid tumors. These include the challenges of CAR-T cell homing and infiltration, the presence of immunosuppressive microenvironments, and the potential for antigen escape in solid tumors. To overcome the known limitations of immune cell therapy, we engineered human induced pluripotent stem cell (hiPSC)-derived NK (eNK) cells armed with CCL19, CCR2B, high-affinity CD16, IL-15, and NKG2D-DAP10 complex. We introduced the six genes into hiPSCs using the piggyBac system and stimulated them to differentiate into NK cells. Overexpression of NKG2D complex and high-affinity CD16 enhanced the antitumor function of the eNK cells. Overexpression of IL-15 prolonged the persistence of the eNK cells in vitro and in vivo. Forced expression of CCR2B enhanced eNK cell tumor infiltration. Forced expression of CCL19 endowed the eNK cells with the ability to recruit dendritic cells. We found that the eNK cells were able to lyse HLA-E-expressing tumor cells, but not normal human cells. These proof-of-concept studies demonstrate the promise of our eNK cells as a novel adoptive cell therapy product for the treatment of solid tumors.

Project description:Human peripheral blood monocytes (Mo) consist of subsets distinguished by expression of CD16 (FCGRIII) and chemokine receptors. Classical CD16- Mo express CCR2 and migrate in response to CCL2, while a minor CD16+ Mo subset expresses CX3CR1 and migrates into tissues expressing CX3CL1. CD16+ Mo produce pro-inflammatory cytokines and are expanded in certain inflammatory conditions including HIV infection. To gain insight into the developmental relationship and functions of CD16+ and CD16- Mo, we examined transcriptional profiles of these Mo subsets in peripheral blood from healthy individuals. Of 16,328 expressed genes, 2,759 genes were differentially expressed and 228 and 250 were >2-fold upregulated and downregulated, respectively, in CD16+ compared to CD16- Mo. CD16+ Mo were distinguished by upregulation of dendritic cell (DC) (SIGLEC10, CD43, RARA) and macrophage (MF) (CSF1R/CD115, MafB, CD97, C3aR) markers together with transcripts relevant for DC-T cell interaction (CXCL16, ICAM-2, LFA-1), cell activation (LTB, TNFRSF8, LST1, IFITM1-3, HMOX1, SOD-1, WARS, MGLL), and negative regulation of the cell cycle (CDKN1C, MTSS1), whereas CD16- Mo were distinguished by upregulation of myeloid (CD14, MNDA, TREM1, CD1d, C1qR/CD93) and granulocyte markers (FPR1, GCSFR/CD114, S100A8-9/12). Differential gene expression in CD16+ and CD16- Mo was confirmed by quantitative real time RT-PCR (i.e., CD16, C3AR1, C1QR1, ICAM-2, CSF1R, CSF3R, CDKN1C, TNFRSF1, and LTB) and flow cytometry (i.e., CSF1R, CSF3R, C1QR1, C3AR1, CD1d, CD43, CXCL16, and CX3CR1). Furthermore, increased expression of RARA and KLF2 transcripts in CD16+ Mo coincided with absence of cutaneous lymphocyte associated antigen (CLA) expression, indicating potential imprinting for non-skin homing. These results suggest that CD16+ and CD16- Mo originate from a common myeloid precursor, with CD16+ Mo having a more MF- and DC-like transcription program suggesting a more advanced stage of differentiation. Distinct transcriptional programs, together with their recruitment into tissues via different mechanisms, also suggest that CD16+ and CD16- Mo give rise to functionally distinct DC and MF in vivo.

Project description:Classical CD16- versus intermediate/non-classical CD16+ monocytes differ in their homing potential and immunological functions; but whether they differentiate into dendritic cells (DC) with distinct contributions to immunity against bacterial/viral pathogens remains poorly investigated. Here, we employed a systems biology approach to identify differences between CD16+ and CD16- monocyte-derived DC (MDDC) with potential clinical relevance Although both CD16+ and CD16- MDDC acquire classical DC markers in vitro, genome-wide transcriptional profiling revealed unique molecular signatures for CD16+ MDDC, including adhesion molecules (CD103), transcription factors (TCF4), enzymes (ALDH1L2), and chemokines (CCL22).

Project description:NKG2D ligands are broadly expressed in cancer. To exploit this, we engineered an adaptor chimeric antigen receptor (CAR) termed NKG2D / Dap10-12 in which NKG2D is co-expressed with a fusion of Dap10 and the Dap12 endodomain. Dap10 was deployed to provide co-stimulation while Dap12 delivers an activation signal via a single immunoreceptor tyrosine-based activation motif (ITAM). NKG2D / Dap10-12 T-cells elicited compelling anti-tumor activity in several solid tumor xenograft models. Disease eradication was accompanied by sustained functional persistence, indicated by reproducible protection from secondary tumor re-challenge. Anti-cancer activity was consistently superior to an analog of a clinical stage linear CAR comprising an NKG2D-CD3 fusion. Mechanistically, functionality of NKG2D / Dap10-12 CAR T-cells was underpinned by transcriptomic re-programming to increase oxidative phosphorylation and ribosome biosynthesis..

Experiment Overall Design: Total Mo were isolated by negative selection using magnetic immunobeads (Monocyte Isolation Kit II, Miltenyi). CD16+ and CD16- Mo fractions were further isolated using CD16 magnetic immunobeads (Miltenyi). Total RNA from Mo pellets was isolated by Trizol extraction and purified using RNeasy columns (Qiagen). The quality of RNA was assessed by visualization of intact bands corresponding to 18S and 28S rRNA on formaldehyde agarose gels. Total RNA (10 µg) from matched CD16+ and CD16- Mo samples isolated from 4 different healthy donors was quality tested using an Agilent 2100 Bioanalyzer chip, reverse transcribed, and hybridized on the GeneChip Human Genome U133 Plus 2.0 Array (Affymetrix), which includes 54,000 probe sets on a single array (i.e., 47,000 transcripts and variants, including 38,500 well-characterized human genes). Primary data analysis performed using GeneSpring software (Biopolymer core facility, Harvard Medical School) generated Excel spreadsheets with relative gene expression values for the 4 matched CD16+ and CD16- Mo subsets.

Project description:Identification of genes differentially expressed between human CD14+CD16- and CD16+ monocyte-derived macrophages generated in the presence of either GM-CSF (termed GM14 and GM16, respectively) or M-CSF (termed M14 and M16, respectively) Human peripheral CD14+CD16- and CD16+ blood monocytes from three independent healthy donors (D1, D2 and D3) were isolated by positive selection from peripheral blood mononuclear cells (PBMC) using magnetic separation systems (MACS, Miltenyi Biotec). Briefly, PBMC were first incubated with MACS anti-CD56 antibody conjugated to paramagnetic microbeads in order to eliminate the NK (CD16+) cell fraction. NK-depleted PBMC were further incubated with MACS anti-CD16 antibody to isolate CD16+ monocytes. CD56-CD16- PBMC were finally incubated with MACS anti-CD14 antibody to obtain the CD14+CD16- monocyte fraction. Monocytes were cultured for 7 days in medium containing either GM-CSF or M-CSF. Total RNA from each condition was extracted using the RNeasy kit (Qiagen) and hybridized to an Agilent Human Whole Genome (4x44) Oligo Microarray. All experimental procedures were performed following manufacturer instructions.

Project description:The new official nomenclature subdivides human monocytes into three subsets, classical (CD14++CD16-), intermediate (CD14++CD16+) and nonclassical (CD14+CD16+). Here, we comprehensively define relationships and unique characteristics of the three human monocyte subsets using microarray and flow cytometry analysis. Our analysis revealed that the intermediate and nonclassical monocyte subsets were most closely related. For the intermediate subset, majority of genes and surface markers were expressed at an intermediary level between the classical and nonclassical subset. There features therefore indicate a close and direct lineage relationship between the intermediate and nonclassical subset. From gene expression profiles, we define unique characteristics for each monocyte subset. Classical monocytes were functionally versatile, due to the expression of a wide range of sensing receptors and several members of the AP-1 transcription factor family. The intermediate subset was distinguished by high expression of MHC class II associated genes. The nonclassical subset were most highly differentiated and defined by genes involved in cytoskeleton rearrangement that explains their highly motile patrolling behavior in vivo. Additionally, we identify unique surface markers, CLEC4D, IL-13RA1 for classical, GFRA2, CLEC10A for intermediate and GPR44 for nonclassical. Our study hence defines the fundamental features of monocyte subsets necessary for future research on monocyte heterogeneity. Three human monocyte subsets, the CD14++CD16- classical, the CD14++CD16+ intermediate and CD14+CD16+ nonclassical subsets were purified using fluorescence activated cell sorting from peripheral blood mononuclear cells. RNA was processed from the three monocyte subsets from 4 individual donors in duplicates, giving a total of 24 samples.
