The results obtained by Afsaneh Gaillard's team and that Pierre Vanderhaeghen at the Institute of Interdisciplinary Research in Human and Molecular Biology show, for the first time, using mice, that pluripotent stem cells differentiated into cortical neurons make it possible to reestablish damaged adult cortical circuits, both neuroanatomically and functionally.

The unsuccessful search for new neurons in adult human and monkey brains is disappointing to many.

Because neurogenesis surges in newborn mice and humans and then tapers to a slow trickle by adulthood, Frankland and colleagues wondered if that explosion of new neurons could help explain the widespread phenomenon of infantile amnesia — the inability of adults to remember events that occurred before they were 2 to 4 years old.

Specifically, stem cell scientists at McMaster can now directly convert adult human blood cells to both central nervous system (brain and spinal cord) neurons as well as neurons in the peripheral nervous system (rest of the body) that are responsible for pain, temperature and itch perception.

Scientists at McMaster University have discovered how to make adult sensory neurons from human patients simply by having them roll up their sleeve and providing a blood sample.

More than 50 years later, scientists have found a way to use radioactive carbon isotopes released into the atmosphere by nuclear testing to settle a long - standing debate in neuroscience: Does the adult human brain produce new neurons?

But the scientists can't be certain these cells are perfect matches for native human motor neurons since it's difficult to obtain samples of cultured motor neurons from adult individuals.

Towards the end of the webinar, we will then look at an example of cells present in the adult human brain that can also be reprogrammed into neurons; and thus demonstrate, and further open potential therapeutic windows of opportunity.

In their study «D - Serine and Serine Racemase are Localized to Neurons in the Adult Mouse and Human Forebrain,» the lab utilized SR deficient (SR - / --RRB- mice, which have < 15 % of normal D - serine levels, to validate and optimize a D - serine immunohistochemical method.

Recently, his lab used induced pluripotent stem (iPS) cells — adult cells made to act like embryonic stem cells — made from skin cells of patients carrying apoE4, or other mutations related to Alzheimer's, to study their effects on the development, survival, and degeneration of human neurons.

GIND investigator Li Gan, PhD, and her collaborators studied the development of neurons born in the hippocampus of adult mice genetically engineered to produce high levels of human Aβ in the brain.

These mice developed hallmark signs of PD in their brains and behavior: loss of dopaminergic neurons in the SNc, impaired generation of new neurons in one of the few regions capable of producing them in adult organisms, and impaired muscle coordination similar to human victims of Parkinson's (as evidenced by difficulty in rearing up on their hind legs)(Figure 2).

The team used genetically engineered mice to study the effects of different human apoE variants on the maturation of neural stem cells or progenitor cells, from which new neurons develop in the adult brain.

The hippocampus is one of the major sites of neurogenesis in the adult human brain, and the circuit that Song's team has identified regulates this neuron - producing process.

And, since scientists have already mapped the adult roundworms» neurons anatomically and functionally, they can easily perform experiments and trace neural circuits in C. elegans tasks that are not possible in humans, yielding valuable information about both species.
