Summary
Klotho protein levels decrease with normal brain aging, accelerating cognitive decline. Enhancing Klotho may offer new treatments for neurodegenerative diseases like Alzheimer's.
Area of Science:
- Neuroscience
- Aging Research
- Molecular Biology
Background:
- Cognitive decline affects over 50% of the aging population.
- Klotho protein, primarily known for kidney functions, is also present in the brain.
- Reduced Klotho expression is linked to aging-like phenotypes and cognitive deficits.
Purpose of the Study:
- To elucidate the functions of Klotho in the brain.
- To investigate Klotho's role in neuroprotection and cognitive aging.
- To explore Klotho as a therapeutic target for neurodegenerative diseases.
Main Methods:
- Analysis of Klotho expression in aging rhesus monkeys.
- Review of existing literature on Klotho's functions in the brain.
- Investigation of Klotho's neuroprotective mechanisms against amyloid and glutamate toxicity.
- Assessment of Klotho's role in oligodendrocyte maturation and myelin integrity.
Main Results:
- Klotho expression is downregulated during normal brain aging in animal models.
- Loss of Klotho accelerates aging phenotypes and cognitive deficits.
- Klotho overexpression extends lifespan and enhances cognition.
- Klotho protects hippocampal neurons and is essential for myelin integrity.
- Klotho is shed into blood and cerebrospinal fluid.
Conclusions:
- Klotho is a neuroprotective protein with critical roles in brain aging.
- Klotho is essential for oligodendrocyte maturation and maintaining myelin integrity.
- Klotho represents a promising therapeutic target for Alzheimer's disease and multiple sclerosis.

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

01:15Neurogenesis and Regeneration of Nervous Tissue
2.0K
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...

1.2K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

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.
