Expression data from mus musculus subjected to traumatic brain injury (TBI) for treatment with cyclophosphamide

ABSTRACT: We inflicted TBI to wildetype (wt) mice in order to establish whether the anti-inflammatory agent cyclophosphamide can be used therapeutically. Cyclophosphamide was found to regulate distinct inflammatory cells such as activated microglia separate from invading phagocytes and dendritic cells. Cyclophosphamide postinjury selectively reduces antigen-presenting dendritic cells. Findings show feasibility of drug development to interfere with brain inflammation.

Expression data from mus musculus subjected to traumatic brain injury (TBI) for treatment with cyclophosphamide

Project description:We inflicted TBI to wildetype (wt) mice in order to establish whether the anti-inflammatory agent cyclophosphamide can be used therapeutically. Cyclophosphamide was found to regulate distinct inflammatory cells such as activated microglia separate from invading phagocytes and dendritic cells. Cyclophosphamide postinjury selectively reduces antigen-presenting dendritic cells. Findings show feasibility of drug development to interfere with brain inflammation. TBI was carried out in injured wt B6 mice for postinjury treatment with cyclophospamide i.p. using saline as a control substance for comparison with injured but untreated mice. Total RNA was prepared from injured cerebral neocortex after three days. RNA samples were also from uninjured wt mice as reference for hybridization on Affymetrix microarrays.

Expression data from chemokine-deficient mus musculus subjected to traumatic brain injury (TBI)

Project description:We inflicted TBI to chemokine-deficient mouse lines in order to establish involvement of various signalling pathways that may be addressed therapeutically. Interacting chemokine pathways in brain regulate distinct inflammatory cells. Activated microglia are separate from invading phagocytes and dendritic cells. Findings show potential targets to interfere with specific inflammatory responses after brain injury. TBI was carried out in Ccl3-/- and Ccr2-/- mice, total RNA prepared from injured cerebral neocortex after three days. RNA samples were from uninjured Ccl3-/- and Ccr2-/- mice as reference for hybridization on Affymetrix microarrays.

Endogenous Tau deletion affects sex-dependent outcome to traumatic brain injury in Drosophila

Project description:Adult male and female Tau-KO flies were inflicted with traumatic brain injury using high-impact trauma device. Brains were dissected at control, 1, 2 and 4 hours post-TBI. Total RNA was extracted from fly brains and 3'mRNA-seq was performed to assess gene expression changes in response to TBI in both sexes. 3 replicates were sequenced for each condition.

Hippocampus-Cerebellum Axis Specific Transcriptomic Stratification to Discriminate Mild from Moderate TBI

Project description:The variations of psycho- and physiological deficits caused by TBI correlate with the degree of brain injury. However, the objective stratification of TBI is yet elusive. A modified closed-head injury Marmarou model was used based on the release of a 500 gram steel slug on top of the rat skull from a height of 100 cm or 120 cm to induce differential injury models for mild TBI and moderate TBI, respectively. The skull was covered by a helmet to mimic the warfighter’s condition in theater. The hippocampus was at the focal point of injury, and the cerebellum, was susceptible to diffused shock (secondary injury). The HC-CB axis coordinates visuomotor performance, which is known to be vulnerable to TBI. The rats that received moderate TBI showed deficient visuomotor performance by the Barnes maze test for longer time periods than those inflicted with mild TBI. The time resolved and HC-CB specific transcriptomic analysis focused on genes that enabled discrimination of mild from moderate TBI at 14d post injury which is equivalent to nearly 1.5 years of human lifetime. The functional analysis elucidated an active healing mechanism in the HC exposed to mild TBI. In contrast, moderate TBI caused delayed healing and active cell death in the HC. In conclusion, the graded brain injuries differentially implicated the HC-CB axis, despite the use of a helmet to reduce the impact. Time resolved functional dynamics informed the distinct consequences of mild vs. moderate TBI.

TBI induced intestinal tissue damage

Project description:Tissue damage precedes GvHD and the events leading up to this inflammatory disease are not well understood. To identify cell populations that may invade the intestinal tract after total body irradiation (TBI), we performed a microarray based gene expression analysis of the intestinal tract isolated from untreated mice or mice that had received 9 Gray TBI 24 h or 48 h previously. The aim of the microarray based gene expression analysis was to identify genes specific for certain cell populations that may contribute to GvHD.

Inhibiting mitochondrial Cytochrome c oxidase downregulates gene transcription after traumatic brain injury in Drosophila

Project description:Adult male and female w1118 flies were inflicted with traumatic brain injury using high-impact trauma device. Brains were dissected at control, 1, 2 and 4 hours post-TBI and exposed to near-infrared (NIR) light at 750 nm for 2 hours. Total RNA was extracted from fly brains and 3'mRNA-seq was performed to assess gene expression changes in response to TBI and NIR eposure in both sexes. 3 replicates were sequenced for each condition.
