Insights

Diroximel fumarate (DRF) and dimethyl fumarate (DMF) may treat multiple sclerosis by reducing ferroptosis, a type of cell death. These fumarates upregulate anti-ferroptotic enzymes, offering a novel anti-inflammatory mechanism specific to the central nervous system.

Area of Science:

  • Cellular Biology
  • Neuroscience
  • Pharmacology

Background:

  • Ferroptosis is a form of iron-dependent cell death involving lipid peroxidation.
  • Neuroinflammation, particularly in multiple sclerosis, involves demyelination and neurodegeneration.
  • Fumarates like dimethyl fumarate (DMF) and diroximel fumarate (DRF) are used to treat multiple sclerosis by activating the Nrf2 pathway.

Purpose of the Study:

  • To investigate if the therapeutic effects of fumarates in multiple sclerosis are linked to modulating ferroptosis sensitivity.
  • To explore the role of anti-ferroptotic enzymes in the mechanism of action of DMF and DRF.

Main Methods:

  • Investigated the effect of DRF on ferroptosis-induced myelin damage in vitro.
  • Analyzed the expression of anti-ferroptotic enzymes in oligodendrocytes, mouse cerebellum, and patient blood cells.
  • Compared the effects in fibroblasts from patients with osteoarthritis or rheumatoid arthritis.

Main Results:

  • DRF treatment diminished ferroptosis-induced myelin damage.
  • Anti-ferroptotic enzymes were upregulated in oligodendrocytes, mouse cerebellum, and patient peripheral blood mononuclear cells upon DRF/DMF treatment.
  • This effect was not observed in primary fibroblasts from arthritis patients, indicating organ and disease specificity.

Conclusions:

  • Fumarate therapy for multiple sclerosis may involve a novel, organ- and disease-specific anti-inflammatory mechanism by modulating ferroptosis.
  • Upregulation of anti-ferroptotic enzymes contributes to the therapeutic benefits of DRF and DMF in neuroinflammatory conditions like multiple sclerosis.

Drugs Affecting Neurotransmitter Synthesis01:29

Drugs Affecting Neurotransmitter Synthesis

Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

Necrosis01:16

Necrosis

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...

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Neurochemical Transmission: Sites of Drug Action

Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...

Antiepileptic Drugs: Glutamate Antagonists

Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...
