Summary
Amyloid precursor protein (APP) and its fragments are crucial for brain function, impacting synaptic plasticity beyond their role in Alzheimer's disease (AD) pathology. Understanding these physiological roles is key to neurobiology and AD research.
Area of Science:
- Neuroscience
- Molecular Biology
- Cell Biology
Background:
- Amyloid precursor protein (APP) is a transmembrane protein vital for brain function.
- APP processing can lead to amyloid plaque formation, a hallmark of Alzheimer's disease (AD).
- Emerging research indicates APP and its fragments have significant physiological roles.
Purpose of the Study:
- To explore the dual role of APP and its fragments in both physiological and pathological states.
- To focus on the contributions of APP and its fragments to synaptic structure, function, and plasticity.
- To summarize mechanisms influencing synaptic dynamics in the hippocampal CA1 region.
Main Methods:
- Literature review of studies on APP processing and function.
- Analysis of research on APP fragments and their impact on synaptic plasticity.
- Focus on mechanisms within the hippocampal CA1 region.
Main Results:
- APP and its fragments play critical roles in synaptic structure, function, and plasticity.
- Mechanisms of APP influence on synaptic dynamics in the hippocampal CA1 region are detailed.
- APP's importance extends beyond amyloidogenesis to fundamental neurobiological processes.
Conclusions:
- APP is essential for normal neurobiological processes, particularly synaptic function.
- Understanding APP's physiological roles offers new perspectives on early AD-related synaptic dysfunction.
- APP's multifaceted roles necessitate a broader research focus beyond its pathological implications.

03:03Amyloid Fibrils
9.9K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

02:47The Synapse
127.4K
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

01:26Alzheimer's Disease: Overview
669
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

01:32Postsynaptic Potential (PSP)
3.4K
Postsynaptic potential (PSP) refers to a change in the electrical potential of a neuron when neurotransmitters released by presynaptic neurons bind to postsynaptic receptors. This potential can either be excitatory, leading to depolarization and ultimately action potential generation, or inhibitory, leading to hyperpolarization and suppression of the postsynaptic neuron.

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.

01:26Chemical Synapses
3.3K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
