Neurogenesis News and Research

RSS

Neurogenesis (birth of neurons) is the process by which neurons are generated. Most active during pre-natal development, neurogenesis is responsible for populating the growing brain.

New technique may help replace brain cells, restore memory

Although brains—even adult brains—are far more malleable than we used to think, they are eventually subject to age-related illnesses, like dementia, and loss of cognitive function.

Maternal immune dysfunction linked to risk of autism with intellectual disability in children

Pregnant women with higher levels of inflammatory cytokines and chemokines, proteins that control communication between cells of the immune system, may be at significantly greater risk of having a child with autism combined with intellectual disability, researchers with the UC Davis MIND Institute have found.

New study sheds light on link between gut microbiome and the brain

Intestinal bacteria that can boost bravery or trigger multiple sclerosis: An increasing body of research results confirms the importance of the "gut-brain axis" for neurology and indicates that the triggers for a number of neurological diseases may be located in the digestive tract.

Specific monocyte immune cells serve as link between gut bacteria and the brain

A special kind of immune cell serves as an intermediary between gut bacteria and the brain. Dr. Susanne Wolf of the Max Delbruck Center for Molecular Medicine in the Helmholtz Association discovered this in tests on mice and published her findings in the journal Cell Reports.

Study reveals new function for CACNA1C gene in psychiatric diseases

A new study shows the death of newborn brain cells may be linked to a genetic risk factor for five major psychiatric diseases, and at the same time shows a compound currently being developed for use in humans may have therapeutic value for these diseases by preventing the cells from dying.

Researchers test potential positive effects of micro-injury in mice modeled with AD

Researchers testing the potential positive effects of "micro-injury" by brief insertion of a small needle into the hippocampal region of mice modeled with Alzheimer's disease (AD) have found that the procedure not only stimulated the hippocampus into regenerative activity, but also reduced β-amyloid plaques, a hallmark of AD.

Salk scientists identify specific cellular switches that clear dying, dead neurons

By adolescence, your brain already contains most of the neurons that you'll have for the rest of your life. But a few regions continue to grow new nerve cells--and require the services of cellular sentinels, specialized immune cells that keep the brain safe by getting rid of dead or dysfunctional cells.

UW-Madison neuroscientist discover genetic machinery that causes maturation in young nerve cells

In one of the first studies to 'read' the genetic activity inside individual brain cells, University of Wisconsin-Madison neuroscientist Xinyu Zhao has identified the genetic machinery that causes maturation in a young nerve cell. The cells under study came from the hippocampus, a memory-related structure that is the only place in a mammal's brain where new neurons can form throughout life.

Researchers investigate effect of naturally-derived pigment ASX on hippocampal function

With the recent rise in popularity of naturally-derived supplements to maintain a healthy body, there has been a great deal of attention toward development of the so-called "brain foods", which can enhance brain function. Of particular importance is the natural red pigment astaxanthin (ASX) abundant in both salmon and in crustaceans such as shrimp and crab.

Aggression influences new nerve cell production in the brain

A group of neurobiologists from Russia and the USA, including Dmitry Smagin, Tatyana Michurina, and Grigori Enikolopov from Moscow Institute of Physics and Technology, have proven experimentally that aggression has an influence on the production of new nerve cells in the brain.

BDNF gene expression signals cognitive reserve against AD progression

Brain-derived neurotrophic factor gene expression contributes to slowing of cognitive decline in older adults and may protect against the effects of Alzheimer’s disease pathology, researchers report in Neurology.

Researchers discover previously unknown mechanism that regulates neurogenesis

Bassem Hassan's team at VIB/KU Leuven has discovered a previously unknown mechanism that is highly conserved between species and which regulates neurogenesis through precise temporal control of the activity of a family of proteins essential for brain development: the proneural proteins.

People suffering from chronic stress, anxiety may be at increased risk for depression and dementia

A scientific review paper warns that people need to find ways to reduce chronic stress and anxiety in their lives or they may be at increased risk for developing depression and even dementia.

UT Southwestern researchers find potential mechanism to prevent epileptic seizures following TBI

UT Southwestern Medical Center researchers have found that halting production of new neurons in the brain following traumatic brain injury can help reduce resulting epileptic seizures, cognitive decline, and impaired memory.

UCA researchers identify compounds that favour generation of new neuronal cells

Many neurology pathologies cause irreversible loss of neurons. They are mostly the so-called neurodegenerative diseases although there exist other causes for a focal loss of neurons, as it is the case in strokes or traumatic brain injuries. All these pathologies lack nowadays of an efficient treatment not being possible to regenerate dead neurons. In fact, although the brain has the ability to regenerate as many studies has proved, this regeneration is very low, ranging from 0.2% to a maximum of 10% depending on the type of injury and the damaged area.

Study sheds new light on the causes of autism

Evidence of autism may be found in the composition and malfunction of the brain's blood vessels, a team of scientists has found. Their research sheds new light on the causes of autism, which previously had pointed to neurological make-up rather than to the vascular system, and identifies a new target for potential therapeutic intervention.

Novel antidepressant appears to be safe, effective against depression in clinical trial

A small clinical trial of a novel antidepressant that stimulates neurogenesis - the production of new brain cells - shows that the compound appears to be safe and may be effective against depression.

Physical exercise can enhance development of new brain cells

Exercise can enhance the development of new brain cells in the adult brain, a process called adult neurogenesis. These newborn brain cells play an important role in learning and memory. A new study has determined that mice that spent time running on wheels not only developed twice the normal number of new neurons, but also showed an increased ability to distinguish new objects from familiar objects.

IMB scientists unravel complex regulatory mechanism involved in brain development

Scientists at the Institute of Molecular Biology in Mainz have unraveled a complex regulatory mechanism that explains how a single gene can drive the formation of brain cells. The research, published in The EMBO Journal, is an important step towards a better understanding of how the brain develops. It also harbors potential for regenerative medicine.

New book highlights sophisticated neurogenic processes in adult mammalian brain

In discrete locations of the adult brain, new neurons are born from stem cells that differentiate, migrate, and integrate into the existing neural network. This process is implicated in normal brain functions such as memory formation and is disrupted in many disease states, including Alzheimer's, schizophrenia, and depression.
