Necrosis01:16

Necrosis

3.7K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Neural Regulation

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.

Alzheimer's Disease: Overview

323
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...

Electron Transport Chain: Complex I and II

9.6K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Long-term Depression01:03

Long-term Depression

2.4K
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.

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

319
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Summary

Neurodegeneration with brain iron accumulation (NBIA) is linked to copper metabolism disorders. Reduced ceruloplasmin levels in serum are a key indicator in NBIA, Wilson

Area of Science:

  • Neurobiology
  • Genetics
  • Metabolic Disorders

Background:

  • Neurodegeneration with brain iron accumulation (NBIA) is a group of inherited disorders.
  • NBIA is characterized by movement disorders and abnormal iron buildup in the basal ganglia.
  • Ten NBIA-associated genes have been identified, with aceruloplasminemia linked to copper metabolism.

Purpose of the Study:

  • To explore the role of ceruloplasmin in NBIA and its connection to copper metabolism.
  • To understand the molecular pathogenesis of NBIA and its implications for brain iron and copper pathways.

Main Methods:

  • Review of existing literature on NBIA, aceruloplasminemia, Wilson's disease, and Menkes' disease.
  • Analysis of the role of ceruloplasmin in iron efflux and copper transport.

  • Examination of serum ceruloplasmin levels in patients with related neurodegenerative conditions.

    • Main Results:

    • Aceruloplasminemia is a form of NBIA directly associated with copper metabolism.
    • Ceruloplasmin plays a critical role in iron efflux from mammalian cells.
    • Decreased serum ceruloplasmin levels are observed in aceruloplasminemia, Wilson's disease, and Menkes' disease.

    Conclusions:

    • The molecular pathogenesis of NBIA involves disruptions in brain iron and copper metabolism.
    • Ceruloplasmin deficiency is a significant factor in certain NBIA forms, highlighting the interplay between copper and iron.
    • Further research into these metabolic pathways can offer new insights into NBIA and related neurodegenerative diseases.
