Nanoscale organization of the endogenous ASC speck

The NLRP3 inflammasome is a central component of the innate immune system. Its activation leads to for-mation of the ASC speck, a supramolecular assembly of the inflammasome adaptor protein ASC. Different models, based on ASC overexpression, have been prop ...

Nanoscale Pattern Extraction from Relative Positions of Sparse 3D Localizations

Suliana Manley, Christian Sieben

Inferring the organization of fluorescently labeled nanosized structures from single molecule localization microscopy (SMLM) data, typically obscured by stochastic noise and background, remains challenging. To overcome this, we developed a method to extrac ...

3D Structure From 2D Microscopy Images Using Deep Learning

Suliana Manley, Christian Sieben

Understanding the structure of a protein complex is crucial in determining its function. However, retrieving accurate 3D structures from microscopy images is highly challenging, particularly as many imaging modalities are two-dimensional. Recent advances i ...

Initial Step of Virus Entry: Virion Binding to Cell-Surface Glycans

Laurent Gillet, Christian Sieben

Virus infection is an intricate process that requires the concerted action of both viral and host cell components. Entry of viruses into cells is initiated by interactions between viral proteins and cell-surface receptors. Various cell-surface glycans func ...

Single-molecule dynamics and genome-wide transcriptomics reveal that NF-kB (p65)-DNA binding times can be decoupled from transcriptional activation

Suliana Manley, Beat Fierz, David Michael Suter, Christian Sieben, Aleksandr Benke, Andrea Callegari

Transcription factors (TFs) regulate gene expression in both prokaryotes and eukaryotes by recognizing and binding to specific DNA promoter sequences. In higher eukaryotes, it remains unclear how the duration of TF binding to DNA relates to downstream tran ...

Multicolor single-particle reconstruction of protein complexes

Pierre Gönczy, Suliana Manley, Kyle Michael Douglass, Christian Sieben, Niccolo Banterle

Single-particle reconstruction (SPR) from electron microscopy (EM) images is widely used in structural biology, but it lacks direct information on protein identity. To address this limitation, we developed a computational and analytical framework that reco ...

Super-resolution imaging of multiple cells by optimized flat-field epi-illumination

Suliana Manley, Kyle Michael Douglass, Christian Sieben, Anna Archetti, Ambroise Justin Lambert

Biological processes are inherently multi-scale, and supramolecular complexes at the nanoscale determine changes at the cellular scale and beyond. Single-molecule localizationmicroscopy (SMLM)(1-3) techniques have been established as important tools for st ...

Genetic characterization of an adapted pandemic 2009 H1N1 influenza virus that reveals improved replication rates in human lung epithelial cells

Christian Sieben

The 2009 influenza pandemic originated from a swine-origin H1N1 virus, which, although less pathogenic than anticipated, may acquire additional virulence-associated mutations in the future. To estimate the potential risk, we sequentially passaged the isola ...
