Insights

Microglia, immune cells in the brain, were thought to protect neurons. New research reveals microglia can harm mature neurons during neurodegenerative diseases.

Area of Science:

  • Neuroscience
  • Immunology
  • Cell Biology

Background:

  • Microglia are the primary immune cells of the central nervous system.
  • Traditionally, microglia are known for their roles in neuronal development, synaptic pruning, and defense against pathogens.
  • Their function in mature brains, particularly in disease states, is complex and not fully understood.

Purpose of the Study:

  • To investigate the role of microglia in neurodegeneration.
  • To re-evaluate the dual nature of microglia in the context of mature neuronal health and disease.

Main Methods:

  • Review of recent findings on microglial function in neurodegeneration.
  • Analysis of studies investigating microglial interactions with mature neurons.

Main Results:

  • Recent studies indicate microglia can exhibit detrimental effects on mature neurons.
  • These myeloid cells may contribute to neuronal loss in neurodegenerative conditions.

Conclusions:

  • The role of microglia in the brain is more complex than previously thought.
  • Microglia possess a dual function, capable of both protection and harm to mature neurons, especially during neurodegeneration.

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...

Alzheimer Disease l: Introduction

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...
Dementia l: Introduction01:22

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...
