BubR1 and brain aging

BubR1 and brain aging

p21 both attenuates and drives senescence and aging in BubR1 progeroid mice.

BubR1 insufficiency occurs with natural aging and induces progeroid phenotypes in both mice and children with mosaic variegated aneuploidy syndrome. In response to BubR1 insufficiency, skeletal muscle, fat, and lens tissue engage p19(Arf) to attenuate senescence and age-related deterioration. Here, we address how p19(Arf) exerts this caretaker role using BubR1 progeroid mice lacking p53 or its ...

Nutrients, Microglia Aging, and Brain Aging.

As the life expectancy continues to increase, the cognitive decline associated with Alzheimer's disease (AD) becomes a big major issue in the world. After cellular activation upon systemic inflammation, microglia, the resident immune cells in the brain, start to release proinflammatory mediators to trigger neuroinflammation. We have found that chronic systemic inflammatory challenges induce dif...

Insulin and brain aging

The world's population is living much longer than in the past. It is crucial to find as many pathological factors that deteriorate the health condition and well-being of elderly people as possible. Loss of activity and functions over time is typical for elderly people. Aging affects brain function, metabolism and structure in different ways, and these effects have multiple etiologies. Cognitive...

Brain Connectivity and Aging

here is growing evidence that in the aging process both the neural and the vascular aspects of brain function are affected. On the neural side, aging is associated with damage to the myelin sheaths and reduction in the total number of nerve fibers, resulting in a reduction in structural connectivity [1]. But connections in the brain are not only structural (i.e. synapses, axons, etc.); equally ...
