Neurobiologist interested in myelin, inflammation, and degeneration of the diseased and aging nervous system.

Würzburg, Munich
Now published in the June issue @NatureNeuro I am especially happy that the artwork my 4-year-old son created (with a little help) was chosen for the cover. #Glial cells in diverse hues as paint splotches, CD8+ #Tcells in red, aberrant #myelin in purple. Thanks @ElisaFlo04 & co!

Thrilled to share our invited Nature Reviews Neuroscience review on the role of peripheral immunity in Alzheimer’s disease. Honored to write this piece with outstanding colleagues @KuchrooLab, @RudyTanzi, @weinerlabhms, Mehdi Jorfi and rising stars from my lab Neta Rosenzweig and Kilian Kleemann. My sincere thanks to Editor Katherine Whalley for the invitation. The time has come to deeply investigate peripheral immunity in AD.

How is the persistence of compartmentalized inflammation sustained in MS? Our new study in @ImmunityCP offers some hints. cell.com/immunity/fulltext/S… Congrats @fngruqng2, @LenaSpieth, @LuLiu_Laura, @StefanBerghoff, @vinitiwari1 et al.

When it comes to aging, the health of even the smallest vessels is critical to maintaining cognitive function. New study in @Nature finds that deterioration of the brain's drainage system contributes to reduced blood supply in deep white matter: nature.com/articles/s41593-0…

Happy to share this review article published in @RockUPress @JExpMed today. Thankyou Mika and @Lucie_JExpMed for the opportunity !! 🥳 @UCSDHealth @TU_Muenchen @DZNE_en #Microglia #Inflammation #Lipids #CNS
Glial cells & lipoproteins coordinate lipid & immune signaling to regulate CNS #inflammation. @vinitiwari1 & Mikael Simons review the relationship btwn lipid metabolism & inflammation & how disruptions in this interplay contribute to neurological disorders hubs.la/Q03BkF6r0

Are T cells in the brain friend or foe? In tauopathy mice, CD8⁺ T cells can slow pathology. In older, wild-type mice, they damage the optic nerve. (@NINDSnews @NIH @tumuenchen ow.ly/5yc650Wos1Y

New study featured on the June cover of Nature Neuroscience used Vizgen’s MERSCOPE® to uncover how microglia and CD8⁺ T cells drive white matter degeneration in aging brains. Learn more: hubs.ly/Q03sqNtp0

nature.com/articles/s41467-0… I am excited to announce our work on how myelin loss culminates in neurodegeneration has been published at Nature Communications. While I have previously covered our findings as a preprint in more detail below, our key findings are:

🎉Excited to share that my PhD work is out @ImmunityCP. We show that epigenetic reprogramming via innate immune training with BCG vaccination or KO of HDAC1/2 in microglia enhances remyelination in aging, highlighting mechanisms of age-associated decline in myelin repair(1/1)
Online now: Innate immune training restores pro-reparative myeloid functions to promote remyelination in the aged central nervous system dlvr.it/TB1L2G
