We didn't know the mechanism for why relapse occurs in multiple sclerosis. @NatureMedicine today: Reactivation of the Epstein-Barr virus and priming of the immune response nature.com/articles/s41591-0…

The future of multiple sclerosis won’t be defined only by new therapies. It will be defined by smarter use of the therapies we already have. Happy to share our paper just published on Neurology Neuroimmunology & Neuroinflammation: neurology.org/doi/10.1212/NX…

After S1PRM withdrawal, OFA vs OCR? 🤔🧠 In our multicenter real-world study, switching to OFA was linked to lower relapse activity, less EDSS/disability worsening, and lower MRI activity vs OCR 📉 Paper: link.springer.com/article/10…

Congrats to @SetPointMed for this landmark study in @NatureMedicine that led to FDA approval for targeting the vagus nerve inflammatory reflex to treat rheumatoid arthritis. rdcu.be/eVUwr.

I had the opportunity to present at the 55th SIN Neurology Congress a study on multi-omic data integration in MS: linking patient transcriptomics, human genetics (coloc + MR), and treatment response to map how current therapies work — and to highlight next-step targets.#neurology

🔬 New study out! We identified a 6-miRNA serum signature in #Neurofibromatosis Type 1 (NF1) using sncRNA-seq + qRT-PCR validation. 🧬 These miRNAs are linked to key cancer pathways and dysregulated across multiple cancers. 📖 Read here: sciencedirect.com/science/ar…

Excited to share our new paper in @ScienceTM 🔬 We show that Treg-derived miR-142-3p is transferred via extracellular vesicles to T cells, suppressing their activation—a novel mechanism of immune tolerance.🧫 Honoured to be part of this team!🌟 science.org/doi/10.1126/scit…

Harvard notified me today that this K99 grant is terminated.
I’m overjoyed to announce that my K99/R00 proposal has been funded by @NIHAging as of today!! I am very excited about the project which is a collaboration with @LehtinenLab to study the blood-CSF barrier with new analytical tools I’ve developed in the @GygiLab. Feeling grateful!!

Switching from fingolimod to siponimod in SPMS patients is safe and well-tolerated. 💊 Our latest study just published—check it out! 🌟 #MS #Neurology #SPMS #Siponimod #Fingolimod jns-journal.com/article/S002…

In this prospective observational study of SPMS patients, we found that switching from fingolimod to siponimod is safe and well-tolerated over a 6-month period, with no increase in disease reactivation.

Key findings: •The main reason for switching was disease progression. •Switchers were younger and had undergone more prior treatments. •Safety signals were minimal and manageable in both groups.
