The goal of this project is to conduct metabolic analyses in a trauma model and perform clinical biomarker studies.
The goal of this project is to diagnose and reverse astroglial metabolic dysfunction after traumatic injury: a translational study in traumatic brain injury patients and human astroglia. During the first phase we will test the hypothesis that detecting astrocyte injury using novel biomarkers, microdialysis and MRI will improve the assessment of patients with traumatic brain injury. The team will also establish rescuing traumatized human astrocytes using a human trauma culture model for future neuroprotective therapies after brain injuries. This is a ‘fist in man’ clinical study.
ImmunArray Inc., EnCor Biotech Inc. ImmunArray and the UCLA-based Wanner lab will work jointly to provide sensitive and specific immunoassays for human TBI blood tests astrocyte injury-defined, AID biomarkers and authenticate already existing prototype assays.
USAARL, Rachel Kinsler, The Mind Research Network, Andy Mayer, and the UCLA-based Wanner lab used novel astroglial biomarkers, MRI and histopathology to detect exacerbation from rough road field transportation and to predict recovery of walking after mild/moderate spinal cord contusion in the Yucatan swine.
This project validated new TBI biomarker candidates and their breakdown products using injured human astrocytes and cerebrospinal fluid and blood samples from severe and mild TBI patients.
In this project we determined reactivity and protein release profiles of human astrocytes after mechanical trauma and defined an astrocyte proteomic signature in cerebrospinal fluid of TBI patients.
In this work differences between wildtype and STAT3-deficient astrocytes were determined using mechanical trauma models in vivo and in vitro. A targeted proteomic screen was conducted that revealed trauma-release proteome and identified STAT3 as an important survival factor for injured astrocytes as well as several novel downstream targets of STAT3 activation during astrogliosis.
This project entailed pilot studies on determining mechanical trauma-induced reactive gliosis and proteomic studies on traumatized human astrocytes and protein confirmation in CSF, plasma and serum samples of TBI patients.
