Scientists have shown that the protein GDF11 can reverse depression-like symptoms in naturally aged mice and in a mouse model of depression. Depressed humans have lower GDF11 as well [1]. Depression and aging Severe mental disorders, including depression, have been linked to significantly shorter lifespans [2]. According to one study, depressed people “have a higher...

Scientists have found that infusing old mice with cerebrospinal fluid obtained from young mice improves their memory by increasing proliferation and differentiation of oligodendrocyte progenitor cells (OPCs) [1]. The fountain of brain youth It has been known for years that blood from young animals can alleviate or even reverse some age-related changes, including cognitive changes,...

Publishing in Aging, a team of Taiwanese researchers has found that a chemical derived from Polygonum multiflorum, a herb native to southeastern China, aids in recovery from traumatic brain injury and encourages brain regeneration. The problem of glutamate BrainThe brain is perhaps the most important organ in the body. While many organs are critical to...

A study published in Aging and Disease has shown how exposure to old serum causes hippocampal progenitor cells (HPCs), which form new neurons, to die. Drawing and testing serum from living people To begin their study, the researchers examined a middle-aged to old (MATO) cohort ranging in age from 52 to 89. This cohort consists...

In a new study, a group of researchers report on their success in priming stem cells to differentiate into dopaminergic neurons in rat brains. Loss of these neurons is a major cause of Parkinson’s disease [1]. Less neurons, more Parkinson's Neuronal degeneration is the culprit behind several age-related disorders, including Parkinson's disease (PD), which affects...

A new study published in Cell Stem Cell has shown how astrocytes, glial cells that perform multiple critical functions in the brain, can become neural stem cells (NSCs) in response to injury. Astrocytes' normal functions The term 'astrocyte', meaning star-shaped cell, refers to a very heterogenous population of cells that perform maintenance, management and constructive...
