01/2021 - Human stem cell models to study host–virus interactions in the central nervous system
Advancements in human pluripotent stem cell technology offer a unique opportunity for the neuroimmunology field to study host–virus interactions directly in disease-relevant cells of the human central nervous system (CNS). Viral encephalitis is most commonly caused by herpesviruses, arboviruses and enteroviruses targeting distinct CNS cell types and often leading to severe neurological damage with poor […]
12/2020 - Structure of human RNA polymerase III
In eukaryotes, RNA Polymerase (Pol) III is specialized for the transcription of tRNAs and other short, untranslated RNAs. Pol III is a determinant of cellular growth and lifespan across eukaryotes. Upregulation of Pol III transcription is observed in cancer and causative Pol III mutations have been described in neurodevelopmental disorders and hypersensitivity to viral infection. […]
12/2020 - 3D FIB-SEM reconstruction of microtubule–organelle interaction in whole primary mouse β cells
This collaborative work is a good example for how members of our team can collaborate with biologists and technologists to improve the quantitative analysis work required to gain insights into essential processes related to human health and pathology, in this particular case into the subcellular organization of insulin producing β cells. Microtubules play a major […]
12/2020 - COVID-19 lessons from the dish: Dissecting CNS manifestations through brain organoids
COVID-19 is increasingly understood as a systemic disease with pathogenic manifestations beyond the respiratory tract. Recent work by Ramani et al (2020) dissects the cellular and molecular mechanisms of SARS-CoV-2’s neurotrophic properties, using viral exposure of human brain organoids. Their findings highlight neurons as primary target of cerebral SARS-CoV-2 infection and uncover its Tau-related neurotoxicity.
