Happy Holidays!
As the year comes to a close, we are wrapping things up with a Lab Cleaning Day and our first-ever Ochsenreiter Secret Santa! 🎅🎄
Wishing everyone a joyous holiday season—stay healthy, happy, and ready for new adventures in the coming year!
Dr. Gaëlle Lentini strikes again!
Explore groundbreaking research on Toxoplasma gondii invasion, brought to you by the Lentini and Favre groups! The latest study uncovers the critical role of RDF3 in rhoptry discharge, shedding new light on parasite-host interactions. Don't miss this collaborative breakthrough—read the full paper now!
Summer school on cryo-FIB milling and in situ cryo-electron tomography (17.-20.06.2024)
Robin was honored to be selected for the prestigious Summer School on Cryo-FIB Milling and In Situ Cryo-Electron Tomography held in Heidelberg from June 17th to 20th, 2024. This exceptional opportunity allowed Robin to spend valuable time with the renowned group of Simone Mattei, focusing on groundbreaking research on Trypanosome mitochondria. The experience provided a deep dive into advanced cryo-electron microscopy techniques and fostered collaborative learning and innovation.
Amazing work featuring Dr. Gaëlle Lentini
Jean-Baptiste Marq et al. investigate cytokinetic abscission, the final stage of cell division. In Toxoplasma gondii, daughter cells form within the mother cell through endodyogeny, but the process of acquiring their plasma membrane is unclear. They demonstrate that five proteins are essential for plasma membrane accumulation during division, and their downregulation prevents abscission, though progeny can still egress but fail to glide and invade, except as conjoined twin parasites.

Now also with a prelights by Jenniver Ann Black…thanks so cool…
for details click here
Simona, Ana and colleagues have done a great job analysing the newest member of the mitochondrial genome segregation machinery in trypanosomes (TAP110). Using a range of techniques including , mass spectrometry regular epifluorescence microscopy, STED super-resolution microscopy as well es ultrastructure expansion microscopy we characterize the positioning in the TAC region and its potential function….big shout to all who participated in this study…
march 2020 new review….
the latest news on rna editing in trypanosomes…thanks to inna and all my colleagues for this comprehensive review…some of the highlights….this review discusses recent developments and introduces a consensus nomenclature for mitochondrial RNA-processing complexes and factors in trypanosoma trucei - mitochondrial rna processing events in kinetoplastid protists include 5′ modification, 3′–5′ degradation, internal sequence changes by u-insertion/deletion mrna editing, and nontemplated 3′ extensions - the specificity of mRNA editing is dictated by grnas while 5′ modifications and 3′ extensions are controlled by diverse pentatricopeptide repeat (ppr) rna-binding factors - antisense transcription plays a central role in delimiting 3′ termini of mature rnas - macromolecular protein and ribonucleoprotein complexes and auxiliary factors involved in these processes have been identified and characterized to varying degrees…

january 2020 swiss trypanosomatid meeting in leysin
three days in the swiss alps with all the labs from switzerland working on these wonderful parasites together with several distinguished researchers in the trypanosomatid field - we had to chance to hear from vsg and surface receptor structure biology in trypanosomes (nina papavasiliou - mark carrington) to lipid biology in t.cruzi (barbara burleigh) and t. brucei (terry smith) - leishmania and its viral partner (nicolas fasel) - many excellent student talks (among them the one from simona on the tac) - on thursday night irina and ana presented their posters in the famous poster night…which was followed by the even more famous night in the stinky bar…altogether a meeting to be remembered
