Ivano Legnini

Ivano Legnini è un biologo molecolare e dei sistemi interessato alla regolazione genica.

Si è laureato in Genetica e Biologia Molecolare all’Università La Sapienza di Roma nel 2012. Ha lavorato sull’RNA non codificante e la regolazione post-trascrizionale dell’espressione genica nel laboratorio di Irene Bozzoni, dove ha completato il dottorato di ricerca nel 2016. Ha poi vinto una EMBO fellowship e si è unito al laboratorio di Nikolaus Rajewsky presso il Max Delbrü Center – Berlin Institute for Medical Systems Biology, dove ha stabilito diverse linee di ricerca, ad esempio sviluppando FLAM-seq per lo studio della regolazione della coda di poli(A) e combinando optogenetica e trascrittomica spaziale per studiare la regolazione spaziale dell’espressione genica nel neurosviluppo usando organoidi. Si è trasferito a Milano e ha avviato il suo laboratorio ad HT a marzo 2023, lavorando nei campi della regolazione genica e del metabolismo dell’RNA, nonché sullo sviluppo di nuove tecnologie genomiche per la perturbazione e la profilazione dell’espressione genica.

    Regulation of mRNA metabolism in immune cells

    Rapid activation of immune cells is critical for host defence. While transcriptional regulation is essential for initiating the immune response, emerging evidence highlights the role of post-transcriptional mechanisms in controlling the speed and intensity of the immune reaction. Splicing, polyadenylation, translation and decay are all regulated to fine-tune the expression of genes crucial for immune […]

    Spatiotemporal, optogenetic control of gene expression in organoids

    Organoids derived from stem cells have become an increasingly important tool for studying human development and modeling disease. However, methods are still needed to control and study spatiotemporal patterns of gene expression in organoids. Here we combined optogenetics and gene perturbation technologies to activate or knock-down RNA of target genes in programmable spatiotemporal patterns. To […]

    Modelling viral encephalitis caused by herpes simplex virus 1 infection in cerebral organoids

    Herpes simplex encephalitis is a life-threatening disease of the central nervous system caused by herpes simplex viruses (HSVs). Following standard of care with antiviral acyclovir treatment, most patients still experience various neurological sequelae. Here we characterize HSV-1 infection of human brain organoids by combining single-cell RNA sequencing, electrophysiology and immunostaining. We observed strong perturbations of […]

    Sites of transcription initiation drive mRNA isoform selection

    The generation of distinct messenger RNA isoforms through alternative RNA processing modulates the expression and function of genes, often in a cell-type-specific manner. Here, we assess the regulatory relationships between transcription initiation, alternative splicing, and 3′ end site selection. Applying long-read sequencing to accurately represent even the longest transcripts from end to end, we quantify […]

    High-resolution molecular atlas of a lung tumor in 3D

    Cells live and interact in three-dimensional (3D) cellular neighborhoods. However, histology and spatial omics methods mostly focus on 2D tissue sections. Here we present a 3D spatial atlas of a routine clinical sample, an aggressive human lung carcinoma, by combining in situ quantification of 960 cancer-related genes across ∼340,000 cells with measurements of tissue-mechanical components. 3D cellular […]
