Summary
Neuroinflammation is now recognized as key in neurodegenerative diseases. Damage-associated molecular patterns (DAMPs) are central to this inflammatory cycle, offering potential therapeutic targets.
Area of Science:
- Neuroscience
- Immunology
- Pathology
Background:
- Neuroinflammation, once controversial, is now integral to neurodegeneration.
- A symbiotic relationship exists between neuroinflammation and neurodegeneration, forming a vicious cycle.
- Damage-associated molecular patterns (DAMPs) are endogenous molecules involved in sterile inflammation.
Purpose of the Study:
- To review the role of DAMPs in central nervous system (CNS) neuroinflammation.
- To explore DAMP-mediated inflammatory responses in chronic neurodegenerative diseases.
- To identify knowledge gaps concerning DAMPs in neurodegeneration for therapeutic development.
Main Methods:
- Literature review focusing on DAMPs, neuroinflammation, and neurodegeneration.
- Analysis of DAMPs' role in CNS immune responses, receptors, and signaling pathways.
- Discussion of DAMP-mediated inflammation in specific neurodegenerative conditions.
Main Results:
- DAMPs are implicated as crucial mediators in the neuroinflammatory cycle driving neurodegeneration.
- Research highlights DAMPs' involvement in sterile inflammation within the CNS.
- Existing knowledge gaps regarding DAMPs' precise functions in neurodegeneration are identified.
Conclusions:
- DAMPs represent a significant nexus in the neuroinflammation-neurodegeneration alliance.
- Understanding DAMPs is critical for developing targeted treatments for neurodegenerative diseases.
- Further research into DAMPs could lead to novel therapeutic and screening strategies.

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...

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...

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

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...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
