Project description:Bioavailability of electron acceptors is probably the most limiting factor in the restoration of anoxic, contaminated environments. The oxidation of contaminants such as aromatic hydrocarbons, particularly in aquifers, often depends on the reduction of ferric iron or sulphate. We have previously detected a highly active fringe zone beneath a toluene plume at a tar-oil contaminated aquifer in Germany, where a specialized community of contaminant degraders co-dominated by Desulfobulbaceae and Geobacteraceae had established. Although on-site geochemistry links degradation to sulphidogenic processes, dominating catabolic (benzylsuccinate synthase alpha-subunit, bssA) genes detected in situ appeared more related to those of Geobacter spp. Therefore, a stable isotope probing (SIP) incubation of sediment samples with 13C7-toluene and comparative electron acceptor amendment was performed. We introduce pyrosequencing of templates from SIP microcosms as a powerful new strategy in SIP gradient interpretation (Pyro-SIP). Our results reveal the central role of Desulfobulbaceae for sulphidogenic toluene degradation in situ, and affiliate the detected bssA genes to this lineage. This, and the absence of 13C-labelled DNA of Geobacter spp. in SIP gradients preclude their relevance as toluene degraders in situ. In contrast, Betaproteobacteria related to Georgfuchsia spp. became labelled under iron-reducing conditions. Furthermore, secondary toluene degraders belonging to the Peptococcaceae detected in both treatments suggest the possibility of functional redundancy amongst anaerobic toluene degraders on site.

Project description:Sipuleucel-T (sip-T) is the only FDA-approved autologous cellular immunotherapy for metastatic castration-resistant prostate cancer (mCRPC). Here, we report the first high-dimensional analyses of sip-T using mass cytometry (CyTOF) and show a lymphoid predominance, with CD3+ T cells constituting the highest proportion (median ~60%) of sip-T, followed by B-cells, and natural killer (NK) and NKT cells. We hypothesized that treatment of sip-T with homeostatic cytokines known to activate/expand effector lymphocytes could augment efficacy against prostate cancer. Of cytokines tested, IL-15 treated sip-T showed the most significant activation/proliferation of effector lymphocytes in an antigen-specific manner, as well as augmentation of tumor cytotoxicity in-vitro. Adoptive transfer of IL-15 treated sip-T into NSG mice resulted in potent prostate tumor growth inhibition compared with control sip-T. Evaluation of tumor-infiltrating lymphocytes revealed a two-to-fourteen-fold higher influx of sip-T and a significant increase in interferon (IFN)-γ producing CD8+ T and NKT cells within the tumor microenvironment (TME) in the IL-15 group.

Project description:Previous research has linked perceived social isolation (loneliness) to reduced antiviral immunity, but the immunologic effects of the objective social isolation imposed by pandemic “shelter in place” (SIP) policies is unknown. We assessed the immunologic impact of SIP by relocating 21 adult male rhesus macaques from 2000 sq-m field cage communities of 70-132 other macaques to 2 wks of individual housing in indoor shelters. SIP was associated with down-regulation of Type I interferon (IFN) antiviral gene expression. This effect emerged within the first 48 hrs of SIP, persisted for at least 2 wks, and abated within 4 wks of return to social housing. A subsequent round of SIP in the presence of a novel juvenile macaque abrogated this effect. These results identify a significant adverse effect of SIP social isolation on antiviral immune regulation in circulating immune cells and they suggest a potential behavioral strategy for ameliorating such effects by promoting pro-social engagement during SIP.

Project description:We developed an adaptation to Split-Pool Recognition of Interactions by Tag Extension (SPRITE) called SPRITE-immunoprecipitation (SIP), which enables us to map genome-wide higher-order interactions that are coupled with the protein of interest. In this study we generated SIP data fo H3K4me3 and pan-promoter mark. We generated SIP maps in two mammalian cell types – mouse embryonic stem cells (mES) and mouse bone marrow derived dendritic cells.
