Feeder-free generation of functional dendritic cells from human pluripotent stem cells

ABSTRACT: The scarcity of primary conventional dendritic cells (cDCs) and the limited effectiveness of monocyte-derived dendritic cells (moDCs) have long hindered progress in human dendritic cell research and immunotherapy. We developed a feeder-free differentiation platform that generates CD1c⁺CD141⁺ hPSC-cDCs phenotypically aligned with CD141⁺ tissue-resident cDC2 subsets found in human tissues. We further optimized the differentiation process using a Design-of-Experiments framework to refine cytokine and serum conditions, enhancing differentiation efficiency while reducing cytokine demand. These hPSC-cDCs exhibit efficient antigen uptake, defined cytokine responses, and robust priming of antigen-specific CD8⁺ T cell proliferation and effector differentiation, outperforming moDCs in direct comparison. Together, this work establishes a robust, and generalizable platform for mechanistic studies and translational development of dendritic cell-based vaccines and standardized ex vivo T cell expansion.

Alpha hemolysin enhances the immune response by modulating dendritic cell differentiation via ADAM10-Notch signaling

Project description:In this study, we used PA0833 a novel protective antigen from Pseudomonas aeruginosa (P. aeruginosa) as the target antigen to evaluate the immune protective effect of the carrier antigen HlaH35A. The transcriptional profiling of bone marrow derived dendritic cells (BMDCs) from mice indicated that HlaH35A predominantly modulates DC maturation, cytokine production, and subsequent T-cell activation. Structural prediction (AlphaFold-Multimer) and fluorescence confocal microscopy confirmed that the specific binding of HlaH35A to ADAM10 enhanced its antigen uptake capacity in dendritic cells. Meanwhile, this interaction between HlaH35A and ADAM10 further activated the downstream Notch signaling transduction in dendritic cells. The HlaH35A-ADM10–Notch axis in cDCs drives their differentiation into type2 cDCs (cDC2s)—particularly the Notch2-dependent cDC2—rather than involving monocyte-derived dendritic cells. This process promotes Th17 and T follicular helper (Tfh) cell responses in draining lymph nodes, leading to elevated antigen-specific IgG1 titers and robust protection against acute Pseudomonas aeruginosa lung infection. Thus, HlaH35A enhances immune response against acute lung infection by modulating cDC differentiation to amplify Th17 and T follicular helper responses, providing a promising Th17/Tfh-oriented vaccine design strategy.

Human Skin CD141+ Dendritic Cells Regulate Cutaneous Immunity via the Neuropeptide Urocortin-2

Project description:Skin immune homeostasis is a multi-faceted process where dermal dendritic cells (DDCs) are key in orchestrating responses to environmental stressors. We have previously identified CD141+CD14+DDCs as a skin-resident immunoregulatory population that is vitamin-D3(VitD3) inducible from monocyte-derived DCs(moDCs), termed CD141hiVitD3 moDCs. We demonstrate CD141+DDCs and CD141hiVitD3 moDCs share key immunological features including cell surface markers, reduced T-cell stimulation, IL-10 production, and a common transcriptomic signature. Bioinformatic analysis identified the neuroactive ligand receptor pathway and the neuropeptide, urocortin-2(UCN2), as a potential immunoregulatory candidate molecule. Incubation with VitD3 up-regulated UCN2 in CD141+DCs and ultraviolet-B(UVB) irradiation induced UCN2 in CD141+DCs in healthy skin in vivo. Notably, CD141+DDC generation of suppressive Tregs was dependent upon the UCN2 pathway as in vivo administration of UCN2 reversed skin inflammation in humanized mice. We propose the neuropeptide UCN2 as a novel skin DC- derived immunoregulatory mediator with a potential role in UVB and VitD3 dependent skin immune homeostasis.

TCR profiling of whole MC38 tumors, treated with PBS + IgG , Cis + PBS + aPD-1, Cis + DCP-IL-12/FLT3L + IgG or Cis + DCP-IL-12/FLT3L + ɑPD-1.

Project description:Dendritic cells (DCs) are specialized myeloid cells with the ability to uptake, process, and present antigens to T lymphocytes. They also generate cytokine and chemokine gradients that regulate immune cell trafficking, activation, and function. Monocyte-derived DCs (moDCs) pulsed with tumor antigens have been used as a platform for therapeutic vaccination in cancer. However, in spite of significant development and testing, antigen-loaded moDCs have delivered mixed clinical results. Here we present a DC therapy that uses a population of mouse or human DC progenitors (DCPs) engineered to produce two immunostimulatory cytokines, IL-12 and FLT3L. In the absence of antigen loading, cytokine-armored DCPs efficiently differentiated into conventional type I DCs (cDC1) and inhibited tumor growth in melanoma and autochthonous liver cancer models. Tumor response to DCP therapy involved synergy between IL-12 and FLT3L and was associated with early NK cell activation and massive effector T cell infiltration, robust M1-like macrophage programming, and ischemic tumor necrosis. Mechanistically, anti-tumor immunity was dependent on endogenous cDC1 expansion and interferon-γ (IFNγ) production and signaling, but did not require CD8+ T cell cytotoxicity. In one application, cytokine-armored DCPs synergized with antigen-specific CAR-T cells to eradicate intracranial gliomas in mice.

Interferon-gamma critically determines dendritic cell function

Project description:A growing body of evidence suggests that inflammatory cytokines have a dualistic role in immunity. In this study, we sought to determine the direct effects IFN-gamma on the differentiation and maturation of human peripheral blood monocyte-derived dendritic cells (moDC). Here, we report that following differentiation of human peripheral-blood monocytes into moDCs with granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-4, interferon-gamma (IFN-gamma) induces moDC maturation and up-regulates the co-stimulatory markers CD80, CD86, CD95, and MHC Class I, enabling moDCs to effectively generate antigen-specific CD4+ and CD8+ T cell responses for multiple viral and tumor antigens. Interestingly, early exposure of monocytes to high concentrations of IFN-gamma promotes monocyte differentiation into macrophages, despite the presence of GM-CSF and IL-4. However, under low concentrations of IFN-gamma, monocytes continue to differentiate into dendritic cells possessing a unique gene-expression profile, resulting in impairments in subsequent maturation by IFN-gamma and an inability to generate effective antigen-specific CD4+ and CD8+ T cell responses compared to standard moDCs. Monocytes differentiated in the presence of low levels of IFN-gamma downregulate IFN-gamma receptor expression, impairing their response to an inflammatory rechallenge. These findings demonstrate the ability of IFN-gamma to impart differential programs on human moDCs which shape the antigen-specific T cell responses they induce. Timing and intensity of exposure to IFN-gamma can thus determine whether moDCs are tolerogenic or immunostimulating. Human monocyte-derived dendritic cells from 4 healthy donors were differentiated with either GM-CSF and IL-4 (n=4) or GM-CSF, IL-4, and IFN-gamma (n=4). These samples were subsequently hybridized to arrays as 4 biological repeats for each of the two treatment conditions.

Unique CD8+ T Cell Priming by Antigen Presenting Plasmacytoid Dendritic Cells Compared to Conventional Dendritic Cells

Project description:Plasmacytoid dendritic cells (pDCs) play a crucial role in orchestrating immune responses, especially against viral infections, and have traditionally been well recognized for their ability to produce type I and type III interferons. However, recent discoveries reveal pDCs to be heterogeneous with more complex functions that include antigen uptake, processing, and presentation. We investigated the antigen cross-presentation ability of pDCs and their role in CD8+ T cell priming, a subject of ongoing debate. Utilizing a novel culturing system of CD8+ T cells and autologous pDCs derived from human blood circulating CD34+ hematopoietic stem and progenitor cells (cHSPCs), we demonstrate that pDCs can efficiently prime CD8+ T cells through cross-presentation, thereby contributing to their expansion and cytotoxic activity. The pDCs’ antigen presentation ability is comparable to that of monocyte-derived dendritic cells (moDCs), which are traditionally known for their efficient antigen presentation capacity. Bioinformatic analysis of the primed CD8+ T cells to uncover their transcriptomic profile following priming by pDCs versus moDCs, revealed distinct genetic signatures, indicating that pDCs prime CD8+ T cells differently than cDCs. These findings challenge the traditional view of pDCs as mere IFN-producing cells, highlighting their significant role in antigen presentation and T cell activation.

Interplay of NLRC4/NLRP3 inflammasomes and Fc-ˠ-Receptors on CD1c+ DC Associates with Pathogenic IFNˠ+IL17+ T cells and RA Severity

Project description:Deregulated myeloid cells infiltrating to the joints likely contribute to rheumatoid arthritis (RA) pathogenesis through multiple mechanisms, including the secretion of proinflammatory cytokines and the induction of pathogenic adaptive Th17 cells, that mediate joint damage. However, the individual contribution of specific myeloid subsets such as CD1c+ and CD141+ conventional dendritic cells (cDC) to RA development and progression has been poorly studied and remains unclear. In particular, the potential molecular mechanisms specifically affecting CD1c+ cDCs in RA patients and their functional implications have not been characterized. Using RNA-seq, multiparametric flow cytometry and in vitro functional assays, we compared in parallel transcriptional, phenotypical and functional characteristics of monocytes, CD1c+ and CD141+ cDCs from the blood and synovial fluid of RA patients.

Single Cell RNA-Seq Analysis Reveals Fate Decision of Human Pre-cDC Determined by Transcription Factor Competition

Project description:Classic dendritic cells (cDCs) play a central role in the immune system and consist of two major subsets: CD141+ cDC (cDC1) and CD1c+ cDC (cDC2). The pre-cDCs is the immediate precursors to both cDC subsets. Previous studies showed that there were two pre-committed pre-cDC subpopulations. However, the key molecular drivers of pre-commitment in human pre-cDCs were not investigated. To address this question, we performed both single cell and bulk RNA sequencing (RNA-seq) of two cDC subsets and pre-cDCs. We inferred a list of sixteen candidate master regulator transcriptional factors (TFs) that can indeed separate pre-cDCs into two sub-populations, with one close to cDC1 and the other close to cDC2. More importantly, these two pre-cDC sub-populations are correlated with ratio of IRF8 to IRF4 expression level more than their individual expression level. Our results suggest the concept that the ratio of antagonistic TFs and their competition determine cDC subset differentiation fate.

Classical dendritic cells are required for dietary antigen-mediated peripheral regulatory T cell and tolerance induction I

Project description:Oral tolerance prevents pathological inflammatory responses towards innocuous foreign antigens via peripheral regulatory T cells (pTreg cells). However, whether a particular subset of antigen-presenting cells (APCs) is required during dietary antigen exposure to instruct naÃ¯ve CD4+ T cells to differentiate into pTreg cells has not been defined. Using myeloid lineage-specific APC depletion in mice, we found that monocyte-derived APCs are dispensable, while classical dendritic cells (cDCs) are critical for pTreg cell induction and oral tolerance. CD11bÂ¬â cDCs from the gut-draining lymph nodes efficiently induced pTreg cells, and conversely, loss of IRF8-dependent CD11bâ cDCs impaired their polarization, although oral tolerance remained intact. These data reveal the hierarchy of cDC subsets in pTreg cell induction and their redundancy during oral tolerance development. Four dendritic cell subpopulations from mouse mesenteric lymphnodes were sorted and compared in their gene expression profile
