Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

Aging

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Alzheimer Disease ll: Pathophysiology

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Long-term Depression

Long-term Depression

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

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

Background:

Endocannabinoids are known as retrograde transmitters.
The cannabinoid system also offers neuroprotection and modulates glial responses.

Purpose of the Study:

To review the cellular and molecular mechanisms of the cannabinoid system's protective effects in brain ageing.
To explore the role of cannabinoids in mitigating age-related neuronal decline.

Main Methods:

Literature review focusing on molecular and cellular mechanisms.
Analysis of experimental evidence on cannabinoid system activity in ageing models.

Main Results:

Cannabinoids regulate mitochondrial activity, act as antioxidants, and modulate clearance processes.
The cannabinoid system influences neurogenesis and brain-derived neurotrophic factor expression.
Cannabinoids suppress neuroinflammation, a key factor in brain ageing and neurodegeneration.

Conclusions:

The cannabinoid system acts as a homeostatic defense mechanism against brain ageing.
CB1 receptor deficiency accelerates age-related learning deficits.
Cannabinoids show promise in preclinical models of neurodegeneration, but clinical evidence is pending.
