Sleep pressure modulates single-neuron synapse number in zebrafish

Sleep pressure modulates single-neuron synapse number in zebrafish

New Nature paper from the Rihel Lab based on the PhD work of Anya Suppermpool

Synaptic Nightlife by Anya Suppermpool

During sleep, the brain weakens the new connections between neurons that had been forged while awake – but only during the first half of a night’s sleep, according to a new study in fish by UCL scientists.

Manganese neurotoxicity in wild-type zebrafish

Manganese neurotoxicity in wild-type zebrafish

New study from the Tuschl Lab: Our manuscript on manganese neurotoxicity in wild-type zebrafish is out – affecting morphology, neurogranin expression and locomotor behaviour! Collaboration between UCL and Dr Monica Folgueira’s group at University of A Coruña, Spain. From Anabel’s work during her lab visit in spring 2022.  https://www.mdpi.com/1422-0067/25/9/4933

Lab Christmas 2023

Lab Christmas 2023

This year the lab celebrated 2023 with Christmas lunch at an Italian restaurant before heading off to axe throwing. Everyone had a great time and managed to leave with all of their fingers. 

Ryan celebrates his birthday!

Ryan celebrates his birthday!

Ryan turned 40 this year. So the lab bought him very useful tools for his old age. Manuela also made him his favourite type of cake - a Muller glia cake. 

Welcome new PhD student Ola Krzywanska

Welcome new PhD student Ola Krzywanska

Ola earned her Master's degree in Neurosciences from Vrije Universiteit Amsterdam and conducted research for her master's thesis at Brigham and Women's Hospital at Harvard Medical School. There, she focused on developing patient-specific stem cell models to assess the safety and efficacy of antisense oligonucleotide therapy for dentatorubral-pallidoluysian atrophy (DRPLA).

Driven by a keen interest in retinal biology and in vivo disease modeling, she joined the MacDonald Lab as a PhD student in October 2023. Her project aims to introduce the African turquoise killifish as a model for understanding molecular and cellular dysfunctions underpinning vision loss with ageing.

Outside the lab, Ola enjoys hiking trips, exploring London and watching cinema classics.

Welcome Lewis!

Welcome Lewis!

Lewis has joined the Bianco lab as a Research Technician. Welcome!

The Wilson & Tuschl Labs are hiring a new Research Technician!

The Wilson & Tuschl Labs are hiring a new Research Technician!

The Tuschl Lab uses manganese transporter mutant zebrafish as models for manganese overload/deficiency in order to dissect how metal dyshomeostasis disrupts neurons, synapses and circuit function with the view to identifying new therapeutic targets. In addition, we are working to develop a novel, orally bioavailable Mn chelator to improve treatment for disorders associated with Mn neurotoxicity. 

This role will provide technical support and research related activities by assisting with experimental procedures and analysis of results within Zebrafish UCL (http://zebrafishucl.org/wilson-lab; http://zebrafishucl.org/tuschl). The successful applicant will assist the lab with maintenance of various zebrafish lines, working on a daily basis with adult fish. The post is available from 1 January 2024 until 31 December 2024 as a fixed term contract. For more information about the role, please contact Prof Steve Wilson (s.wilson@ucl.ac.uk) or Dr Karin Tuschl (k.tuschl@ucl.ac.uk).

Lab BBQ

Summer in London now seems to be well and truely over, but the lab did manage to get together for a lovely BBQ on the last sunny (and very hot) Saturday of the season.

MacDonald lab at the 12th European Zebrafish Meeting

Manuela Lahne, Ryan MacDonald and Gregory Patient went to the annual European Zebrafish Meeting. Gregory presented his work with Iterative Bleaching Extends Multiplexity (IBEX) which is a highly multiplexed immunohistochemistry technique which allows multiple rounds of immunohistochemistry to be performed on a single tissue sample. More information can be found here.

Welcome Artur

We would like to welcome Dr Artur R Fernandes to the MacDonald lab. He is here as a visiting Postdoc.

Asaph wins UCL Early Career Neuroscience Prize

Asaph wins UCL Early Career Neuroscience Prize

We’re really proud of Asaph Zylbertal who won the UCL Early Career Neuroscience Prize (Advanced category) for his beautiful study about how recurrent interactions in the optic tectum help explain the interactions between sensory input and the brain’s internal state.

Here’s Asaph giving his talk at the UCL Neuroscience Symposium and receiving the award from Prof Trevor Smart.
