Project description:Bulk RNA-sequencing was performed to characterize the gene expression profile of microglia at acute and chronic timepoints following traumatic brain injury and nasal anti-CD3 treatment. We further investigated how the chronic microglial transcriptomic profile is modulated following traumatic brain injury and nasal anti-CD3 treatment in female mice with severe TBI, and in male mice with a delayed administration of treatment post-injury.
Project description:Investigating the impact of blocking the IL-10 receptor on the gene expression profile of microglia following chronic traumatic brain injury and nasal anti-CD3 treatment.
Project description:To investigate whether the immunomodulatory effects of nasal anti-CD3 on the microglial transcriptomic profile following TBI is dependent on Tregs, we employed adoptive transfer experiments
Project description:Traumatic brain injury (TBI) can lead to significant neuropsychiatric problems and neurodegenerative pathologies, which develop and persist years after injury. Neuroinflammatory processes evolve over this same period. Therefore, we aimed to determine the contribution of microglia to neuropathology at acute (1-day post-injury; dpi), subacute (7 dpi), and chronic (30 dpi) time-points. Microglia were depleted with PLX5622, a CSF1R antagonist, prior to midline fluid percussion injury in male mice and cortical neuropathology/inflammation was assessed using a neuropathology mRNA panel. NanoString Neuropathology gene expression panel was used to quantify expression from RNA microdissected from the mouse cortex.
Project description:RNA-SEQ analysis of antigen-specific CD8 T cells sorted from murine liver tumors and from the spleens of Listeria-infected mice at different early timepoints following adoptive transfer. We sequenced naive antigen-specific CD8 T cells from spleens for comparison.
Project description:Bulk RNA-sequencing was performed to investigate the transcriptomic signature of phagocytic and non-phagocytic microglia following traumatic brain injury and nasal anti-CD3 treatment.
Project description:We isolated visceral adipose tissue (VAT) Tregs from Foxp3.YFP-Cre Bmal1WT or Foxp3.YFP-Cre bmal1flox mice fed a normal lean diet or a high-fat diet. VAT Tregs were also sorted after adoptive transfer. We found that Bmal1KO Tregs are more activated in lean mice, after 4 weeks HFD and after adoptive transfer, but loseVAT Treg signature after 16 weeks of high-fat diet feeding.
Project description:We performed bulk RNA-sequencing analysis of brain and blood CD4+Foxp3+ Treg cells from sham and injured mice to characterize the gene expression profile of Tregs following traumatic brain injury and nasal anti-CD3 treatment
Project description:Traumatic brain injury (TBI) induces a complex cascade of molecular and physiological effects. This study proposes to investigate the gene expression profile in cortex and hippocampus over early time points, following two different injury severities. These results will complement prior knowledge of both metabolic and neuroplastic changes after TBI, as well as serve as a starting point to investigate additional gene families whose expression is altered after TBI.,To characterize the profile of gene expression following a diffuse traumatic brain injury of varying severity in adult rats. ,Distinct patterns of gene expression following traumatic brain injury will occur in a time- and injury-dependent fashion. In particular, changes in expression of enzymes involved in energy metabolism and neuroplasticity will be detected.,Adult rats will be subjected to mild and severe lateral fluid percussion injury OR sham surgery without injury. At various post-injury timepoints (0.5, 4 and 24 hours), animals will be sacrificed, brain regions (parietal cortex and hippocampus, ipsilateral and contralateral to injury) will be dissected and RNA isolated. RNA will be used to synthesize cRNA probes for microarray hybridization. RNA from 2 matched animals will be pooled onto a single chip (U34A rat, Affymetrix). Comparisons will be made between sham and injured animals, with brain region, injury severity, and post-injury time point as the experimental variables.
