Insights

Anti-B-cell therapies, such as ocrelizumab, are effective for multiple sclerosis (MS). This anti-CD20 antibody shows clinical and MRI benefits in relapsing MS and primary progressive MS (PPMS), even impacting leptomeningeal changes.

Area of Science:

  • Neuroimmunology
  • Pharmacology

Background:

  • Anti-B-cell therapies targeting CD20 are emerging treatments for multiple sclerosis (MS).
  • Ocrelizumab, an anti-CD20 monoclonal antibody, has demonstrated efficacy in clinical trials.

Purpose of the Study:

  • To review the clinical and MRI efficacy of ocrelizumab in multiple sclerosis.
  • To highlight the potential of ocrelizumab in aggressive MS and its effect on leptomeningeal changes.

Main Methods:

  • Review of three phase III clinical studies evaluating ocrelizumab in MS.
  • Case example of ocrelizumab use in aggressive MS with MRI analysis.

Main Results:

  • Ocrelizumab demonstrated clinical and MRI efficacy in both relapsing MS and primary progressive MS (PPMS).
  • The use of ocrelizumab in aggressive MS showed potential effects on leptomeningeal folliculi visualized by contrast-enhancing MRI.

Conclusions:

  • Ocrelizumab is a clinically effective anti-CD20 therapy for multiple sclerosis, including PPMS.
  • Ocrelizumab may influence pathological processes in aggressive MS, such as leptomeningeal inflammation.

Nucleophilic Addition to the Carbonyl Group: General Mechanism01:18

Nucleophilic Addition to the Carbonyl Group: General Mechanism

The carbonyl carbon in an aldehyde or ketone is the site of a nucleophilic attack due to its electron-deficient nature. Depending on the strength of the incoming nucleophile, the reaction occurs via different mechanistic pathways.
A stronger nucleophile can directly attack the electrophilic center, the carbonyl carbon. The HOMO orbital of the nucleophile interacts with the LUMO (π* antibonding) orbital present on the carbonyl carbon. This interaction breaks the π bond and shifts the π...

Depolarizing Blockers: Mechanism of Action01:28

Depolarizing Blockers: Mechanism of Action

Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because...

Local Anesthetics: Mechanism of Action01:23

Local Anesthetics: Mechanism of Action

Local anesthetics (LAs) block sensory and motor impulses by inhibiting the sodium channels on the nerve cell membranes. This induces temporary loss of sensation, relieving pain in a specific body area.
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...

Radical Anti-Markovnikov Addition to Alkenes: Mechanism01:17

Radical Anti-Markovnikov Addition to Alkenes: Mechanism

The reaction of hydrogen bromide with alkenes in the presence of hydroperoxides or peroxides proceeds via anti-Markovnikov addition. The radical chain reaction comprises initiation, propagation, and termination steps.
The mechanism starts with chain initiation, which involves two steps. In the first chain initiation step, a weak peroxide bond is homolytically cleaved upon mild heating to form two alkoxy radicals. In the second initiation step, a hydrogen atom is abstracted by the alkoxy...

Indirect-Acting Cholinergic Agonists: Mechanism of Action01:18

Indirect-Acting Cholinergic Agonists: Mechanism of Action

Indirect-acting cholinergic agonists work by interacting with an enzyme called acetylcholinesterase (AChE) in the synaptic cleft. They can be reversible or irreversible inhibitors and have different effects on the enzyme.
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex,...

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action01:17

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action

Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...
