Dr. Justin Abbatemarco and Dr. Bob Fox discuss serum neurofilament light chain as a marker for MS disease activity. They explore the challenges of interpreting these levels against normal protein turnover.
Serum neurofilament light can indicate neuronal health and disease activity in neurological conditions.
Baseline turnover of neurofilament complicates its interpretation as an indicator of neuronal damage in diseased states.

Measurement of Serum Neurofilament Light and Its Role in Neurological Diseases
Serum neurofilament light, a protein family integral to neuron structure, offers insights into neurological conditions due to its stability in body fluids like blood. Its release from injured neurons is detectable in blood, providing a measurable indicator of neuronal health. Despite background levels in healthy individuals, deviations from baseline levels can signify disease activity, making it a valuable marker for assessing neurological conditions.
Natural Turnover of Neurofilament in Patients Without Neurological Disease
Neurofilament light undergoes a natural turnover process in individuals without neurological diseases, where its presence in cerebrospinal fluid and blood reflects normal cell maintenance. This physiological release complicates the interpretation of neurofilament levels in disease states, as distinguishing between baseline turnover and disease-related elevation becomes challenging. Understanding this baseline turnover is crucial for accurately evaluating neurofilament as an indicator of neuronal damage.

Serum Neurofilament Light Chain and Disease Activity in MS Patients
In the first episode of this two-part series, Dr. Justin Abbatemarco and Dr. Bob Fox walk through what serum neurofilament light chain is measuring and how it applies more broadly to neurological disease.
