Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

362
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Mitochondrial Membranes01:45

Mitochondrial Membranes

13.1K
A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Mitochondria01:37

Mitochondria

15.7K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

15.3K
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...

Area of Science:

  • Neuroscience
  • Biochemistry
  • Pathology

Background:

  • Mitochondrial dysfunction is central to neuroinflammation and oxidative stress in epilepsy.
  • Neuronal damage in epilepsy links brain injury, neuroinflammation, and mitochondrial issues.
  • This interplay is crucial in epileptogenesis.

Purpose of the Study:

  • To review preclinical and clinical evidence on drugs targeting proteins involved in neuroinflammation and mitochondrial dysfunction in epilepsy.
  • To elucidate the correlation between mechanisms of neuroinflammation and mitochondrial dysfunction.
  • To understand seizure-induced pathological changes and their link to hyperexcitability.

Main Methods:

  • Systematic literature review of major scientific databases (PubMed, Scopus, etc.).
  • Analysis of preclinical and clinical data on drugs targeting nuclear, cytosolic, and mitochondrial proteins.
  • Evaluation of evidence for inflammatory mediators and pro-apoptotic proteins.

Main Results:

  • Elevated inflammatory mediators and pro-apoptotic proteins correlate with inflammatory responses in epilepsy.
  • Repetitive seizures exacerbate mitochondrial redox mechanisms and neuroinflammation susceptibility.
  • Neuroinflammatory cascades (NF-kB, MAPK, etc.) are activated, leading to mitochondrial damage and hyperexcitability.

Conclusions:

  • Neuroinflammation-mediated mitochondrial oxidative stress presents therapeutic opportunities in epilepsy.
  • Targeting mitochondrial dysfunction linked to neuroinflammation is a promising future drug treatment strategy.
  • Understanding these common intracellular mechanisms is key for developing novel epilepsy therapies.
