🩸 Neurofilament Light Chain Neurodegeneration Marker Simulator

Neurofilament Light Chain as Axonal Cytoskeleton Component

Placeholder: NfL is a core structural protein of the axonal cytoskeleton.

• Type IV IF: Protein class (intermediate filament placeholder)
• Axon: Location (cytoskeletal scaffold placeholder)
• NfM / NfH: Partners (neurofilament triplet placeholder)
• Axon caliber: Function (structural support placeholder)

Structural role placeholder heading

Placeholder text describing neurofilament light chain structural function in axons.

Release of NfL Into Blood Upon Axonal Injury

Placeholder: axonal damage releases NfL into CSF and blood.

• Axon injury: Release trigger (placeholder mechanism)
• CSF → blood: Compartment (placeholder pathway)
• ~weeks: Half-life (placeholder kinetics)
• Simoa assay: Detection (placeholder method)

Release mechanism placeholder heading

Placeholder text describing NfL release kinetics after axonal damage.

NfL as a Broad Neurodegeneration Marker

Placeholder: elevated NfL reflects neuronal damage broadly, not one disease.

• Many: Conditions (broad marker placeholder)
• Low: Specificity (disease-non-specific placeholder)
• High: Sensitivity (damage detection placeholder)
• Screening: Use (general indicator placeholder)

Specificity limitation placeholder heading

Placeholder text describing why NfL elevation is non-specific across neurodegenerative diseases.

Differentiating Alzheimer's Disease From Other Neurodegeneration

Placeholder: NfL must be combined with other markers for diagnosis.

• Aβ42/40, p-tau: Companion markers (placeholder panel)
• Limited: AD specificity alone (placeholder note)
• Improved: Combined panels (placeholder accuracy)
• FTD, ALS, MS: Overlap conditions (placeholder list)

Differential diagnosis placeholder heading

Placeholder text describing combined biomarker panels for Alzheimer's differentiation.

Serial NfL Monitoring for Disease Progression

Placeholder: repeated NfL measurement tracks progression and therapy response.

• Months: Monitoring interval (serial sampling placeholder)
• High: Trend value (longitudinal utility placeholder)
• Trackable: Therapy response (placeholder application)
• Endpoint: Trial use (clinical trial placeholder)

Longitudinal tracking placeholder heading

Placeholder text describing serial NfL monitoring for progression tracking.

Placeholder key insight about trend-based clinical value of serial NfL testing.
