P108: Microglia in Traumatic Brain Injury
Microglia is one of the first innate immune components. These cells account about 5 to 10% of the entire adult brain cells and are activated by trauma. Complex-mediated inflammatory responses occur through cellular and molecular events during and after the traumatic brain injury (TBI). In-lesion area astrocytes, microglia, and damaged neurons begin to secrete cytokines and chemokines. Microglia...
متن کاملMethionine sulfoxide reductase regulates brain catechol-O-methyl transferase activity.
Catechol-O-methyl transferase (COMT) plays a key role in the degradation of brain dopamine (DA). Specifically, low COMT activity results in higher DA levels in the prefrontal cortex (PFC), thereby reducing the vulnerability for attentional and cognitive deficits in both psychotic and healthy individuals. COMT activity is markedly reduced by a non-synonymous single-nucleotide polymorphism (SNP) ...
متن کاملCatechol-O-methyl transferase and schizophrenia.
Catechol-O-methyl transferase (COMT) is an enzyme involved in the degradation of dopamine. The most commonly examined polymorphism within the COMT gene is Val108/158Met polymorphism, which results in three to fourfold difference in COMT enzyme activity. It is particularely important in prefrontal cortex, since COMT activity is the most important regulator of the prefrontal dopamine function. Gi...
متن کاملO 27: Traumatic Brain Injury and Inflammation
Traumatic brain injury (TBI) is a significant public health concern in our country, because of placing in top three most common causes of death and substantial direct and indirect costs to society. The incidence of TBI in our country is 1.7 times of international incidence. Traumatic brain injury induced by primary and secondary mechanisms that give rise to death and neurologic morbidity in pat...
متن کاملTraumatic Brain Injury, Microglia, and Beta Amyloid
Recently, there has been growing interest in the association between traumatic brain injury (TBI) and Alzheimer's Disease (AD). TBI and AD share many pathologic features including chronic inflammation and the accumulation of beta amyloid (Aβ). Data from both AD and TBI studies suggest that microglia play a central role in Aβ accumulation after TBI. This paper focuses on the current research on ...
