Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Long-term Potentiation

Long-term Potentiation

Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Background:

Yamanaka factors (YFs) reprogram somatic cells into induced pluripotent stem cells.
Understanding YF in vivo function is crucial for regenerative medicine.

Purpose of the Study:

Investigate the in vivo effects of transient Yamanaka factor expression.
Assess YF impact on neurogenesis and neuroprotection in an Alzheimer's disease model.

Main Methods:

Transient in vivo induction of Yamanaka factors during embryogenesis.
Utilized an adult mouse model with Alzheimer's disease-associated amyloidosis.

Main Results:

Transient YF expression enhanced neurogenesis.
YF induction demonstrated resilience against neurodegeneration in the Alzheimer's model.
