ABSTRACT: TLR signaling in PBMCs acquired from BALB/c mice (10 days post-BMT) after being transplanted with T-cell depleted bone marrow alone (BMTCD), or in combination with TLR2,4,7-tolerant splenocytes, over their PBS-pretreated counterparts.
Project description:Murine splenocytes were isolated from the spleens of C57BL/6J mice and were pretreated in vitro for three days in the presence of PBS, Pam3CSK4 (1 μg/ml), high pure LPS from E.coli O111:B4 (100 ng/ml) and R848 (5 μg/ml). BALB/c irradiated recipients, were transplanted with T-cell depleted bone marrow alone, or with the aforementioned pretreated splenocytes, and 10 days after, PBMCs from all experimental groups were collected for TLR signaling pathway analysis.We used Qiagen Toll-like Receptor RT2 Profiler PCR Array kit to quantitate gene expression profiling of the TLR signaling pathway.

PBS-treated splenocytes served as negative control. We used Qiagen Toll-like Receptor RT2 Profiler PCR Array kit to quantitate gene expression profiling of the TLR signaling pathway.
Project description:BMCs from BMT recipient mice transplanted with BMCs-expressing EZH2-mutant were analyzed using Affymetrix GeneChip Mouse430_2 BMCs were extracted from BMT recipient mice transplanted with ABCG2-expressing BMCs and analyzed using Affymetrix GeneChip Mouse430_2
Project description:Deletion of the NMD component UPF2 in adult liver and response to partial hepatechtomy. Lethally irradiated Upf2flox/flox and Upf2flox/flox; Mx1Cre animals were transplanted with WT BM at 10-12 weeks of age. 5-6 following transplantion the bone marrow transplanted (BMT) animals were injected 3 times with poly-IC (Days 0, 2, 4), which facilitates Cre-mediated deletion in BMT Upf2flox/flox; Mx1Cre (hitherto UPF2 null) but not in BMT Upf2flox/flox control (hitherto WT) mice. A day 14 mice were subjected to partial hepatechtomy (0 hours) and sacrificed after 36 hours (36 hours)..
Project description:We report the gene expression differences between OT-1 T cells activated alone or in the presence of TLR1/2 (Pam3CSK4) or TLR7 (Gardiquimod). By activating OT-1 splenocytes in the presence or absence of the TLR agonists, isolating RNA from purified CD8+ T cells we show that cells activated in the presence of either TLR1/2 or TLR7 agonists had similar transcriptional profiles demonstrating an increase in Th1 cytokine expression over cells that were activated alone. This study provides a key piece of information for those designing T cell mediated therapies.
Project description:The goals of the study are to compare differenely expressed genes in allogeneic and syngeneic CD3+ T cells isolated from splenocytes of allogeneic (donor: C57BL/6, host: Balb/c) and syngeneic (donor: Balb/c, host: Balb/c) HSCT mice.

Project description:The goals of the study are to compare differently expressed genes in allogeneic and syngeneic CD4+ T cells isolated from splenocytes of allogeneic (donor: C57BL/6, host: Balb/c) and syngeneic (donor: Balb/c, host: Balb/c) HSCT mice.
Project description:Xenotransplantation holds the promise of providing an unlimited supply of donor organs for terminal patients with organ failure. The gal carbohydrate results in rejection of wild type pig grafts, however, chimerism established by expression of the GalT gene prior to transplantation in GalT knockout mice results in tolerance to Gal+ heart grafts. We used microarrays in order to further understand the early events that occur within grafts that demonstrate tolerance. Experiment Overall Design: The GalT BMT recipient is a GalT knockout mouse which recieved GalT gene transduced allo-bone marrow cells transplantation after sublethal irradiation. A heart of wild type C57BL/6 was heterotopically transplanted into the recipient after GalT BMT. Syngeneic Control recipient is a wild type C57BL/6 transplanted a heart of wild C57BL/6.
