Molecular imaging of microglia/macrophages in the brain.

abstract：:Dentate neurogenesis, important for learning and memory, declines dramatically by middle age. Although studies have shown that this age-related decrease can be reversed to some extent by exogenous applications of mitogenic factors, it is unclear whether one or more of these factors exhibits decline by middle age. We h...

abstract：:The creatine kinase isoenzymes play an important role in maintaining ATP levels in some cell types during times of high energy demand. We have previously shown in primary cell cultures from rat brain that glial cells express much higher levels of brain creatine kinase (CKB) mRNA than neurons. In a separate earlier stu...
