The new article “Quantitative Systems Pharmacology Model That Describes Neurofilament Light Dynamics During Alzheimer's Disease Progression” by Polina Maliukova, Tatiana Karelina was published in CPT: Pharmacometrics & Systems Pharmacology Journal on June 17, 2025.
Tatiana Karelina, Head of the Neurodegenerative Diseases Modeling Group, highlights, “Neurofilament L is considered an important biomarker of degeneration and is often investigated in clinical trials related to AD, PD, MS. Its dynamics in CSF may indicate cytoskeletal degradation process. However, in AD trials, for instance, the effect on neurofilament and on another biomarker of degeneration, tau, may differ significantly. Therefore, it is difficult to estimate how the therapy slows down cytoskeletal degradation. In our study we tried to understand the mechanisms on which neurofilament secretion depends and how different types of therapy can impact neuronal cytoskeleton.
We described neurofilament dynamics in different ATN patient populations by means of assumptions and available data on intracellular processes in AD and validated the model against different therapies. It is worth mentioning that the model surely does not cover all the diversity of pathological processes but rather it is a reduced representation of groups of pathological processes. When developing the model, we tried to strike a balance between mechanistic description and clarity of the model. At the same time in the future, it can be used both in a simplified and vice versa, in a complicated detailed version, to explore new targets and their combinations."

To predict unpredictable: a platform for modeling of the high-selective oncology drugs was created
Moscow, Russia, July 14, 2017. The scientists from BIND RUS and InSysBio (www.insysbio.ru) published a joint research of the new class of anti-oncology treatment in the Journal of Controlled Release. Unique nanoparticles enriched with medications can deliver its content targeted to the tumor site, and the parameters of their effectiveness are programmed during the forming phase.
