Age-related Dysregulation of Cytokine CXCL10 is Linked to Cognitive Decline

Chronic inflammation is a hallmark of aging pathology [1], [2]. Chronic inflammation is a risk factor for decreased cognitive performance [3], [4] and dementia [5] in older populations. Bradborn et al analyzed 35 cytokines in humans from the MyoAge study [6] to determine which are important for cognitive decline and …

Epigenetic Dysregulation Within the Brainstem in Alzheimer’s Disease

The elusive nature of the early stages of Alzheimer’s disease (AD) impedes scientific breakthroughs in diagnostics or efficient therapeutics for this devastating disorder. To date, the long-prevailing theories of genetic contribution do not adequately explain the pathogenesis of the disease and, alternatively, epigenetic regulation has been proposed as a key …

Does Loss of DNA Methylation and Hydroxymethylation in the Brain Lead to Loss of Memory?

5-methylcytosine (5-mC) and 5-hydroxymethycytosine (5-hmC) are two major epigenetic modifications of DNA.  Dynamic changes in 5-mC and 5-hmC levels are tightly regulated and impact neural cell development, differentiation, and other biological functions. Deregulation of 5-mC and 5-hmC has also been implicated in various human diseases. However, whether 5-mC and 5-hmC …
