Preprint alert: Striatal neurons in the eIF4-tg ASD mouse show dramatically increased activity-dependent plasticity. Unexpectedly, this is NMDA-dependent, not dopamine-driven. Excess protein synthesis alone can generate aberrant plasticity. www.biorxiv.org/content/10.6...

Dopamine’s secret agent: serotonin Dopamine suppresses GABA release from striatal terminals in the substantia nigra pars reticulata. Molinari et al. recently demonstrated that this suppression is frequency-dependent—instituting a high-...

Happy to share this Spotlight article, drawing attention to recent work by @borgkvistlab.bsky.social on the mechanisms of dopamine action in the SNr.

Read our summary and then read their paper! Many cool implications!

Thank you @talialerner.bsky.social. We are incredibly grateful for highlighting our work, and we really appreciate you sharing your perspective on the paper.

Dopamine and serotonin cotransmission filters striatonigral synaptic activity via 5-HT1B receptor activation A monoaminergic high-pass filter regulates basal ganglia output activity.

A study by @borgkvistlab.bsky.social published in Science Advances shows that dopamine modulates basal ganglia output not via DA receptors, but through serotonin and 5-HT1B activation. Findings in mice suggest a new mechanism relevant to #Parkinsons therapy. #Neuroscience 🧪 doi.org/10.1126/scia...

💊✨ Exciting new collaboration with Laurence Lafanechère’s team (Grenoble)!
Our new study introduces Carba1, a bifunctional carbazole compound that protects against chemotherapy-induced peripheral neuropathy (CIPN) — a major unmet need in cancer therapy.

Maternal aggression driven by the transient mobilisation of a dormant hormone-sensitive circuit - Nature Communications Mothers can fiercely defend their young, but how the brain triggers this response remains to a large extent a mystery. Here, authors show that a dormant, hormone-sensitive brain circuit switches on to spark maternal aggression during the lactation period.

1/n. New paper from us: here we explore the mechanisms underlying maternal aggression in mice as a means of addressing how an individual transiently can gain access to a behaviour normally outside of its repertoire. Lead investigator Stefanos Stagkourakis (not on 🦋)🧵:

Postnatal reduction of eIF4E overexpression in D1-SPNs ameliorates KCNQ dysfunction, hyperexcitability and ASD-like behaviours. An imbalance between the direct and indirect pathways of the striatum has been implicated in the pathophysiology of ASD, which corresponds with an increase in repetitive behaviours and hyperactivity. ...

Excited to share our study on striatal dysfunctions in the eIF4E autism model! Understanding brain networks in ASD is key for targeted therapies. Huge thanks to PhD candidate Alina Aaltonen and our funders @Vetenskapsradet, @Wstiftelserna, @StratNeuro!

What a fantastic Lucia performance by Biomedicum's own choir! The Lucia tradition marks the beginning of the darkest week of the year with only 5 hours of daylight in Stockholm. Heart-warming traditions like these are particularly important to maintain spirits high. @karolinskainst.bsky.social

Dysregulated acetylcholine-mediated dopamine neurotransmission in the eIF4E Tg mouse model of autism spectrum disorders Basal ganglia dysfunction potentially causes behavioral alterations in ASD. Carbonell-Roig et al. show that the eIF4E Tg mouse model of ASD exhibits behavioral inflexibility and impaired striatal dopa...

5-HT1B receptors mediate dopaminergic inhibition of vesicular fusion and GABA release from striatonigral synapses The substantia nigra pars reticulata (SNr), a crucial basal ganglia output nucleus, contains a dense expression of dopamine D1 receptors (D1Rs), along with dendrites belonging to dopaminergic neurons ...
