Structural HIV-1 Env Trimers Dynamics on Living T Cells

In this article, we focus on the molecular mechanism of the Env protein as it interacts with T cell, the primary target of HIV-1 [Carlon-Andres I et al 2021]. Multiphoton and fluorescence lifetime…

The lung tissue was immunofluorescently stained with Keratin-5 (green) and PDL-1 (red). Image courtesy of Andrew Beppu, Stripp Lab, Cedars Sinai Medical Center, Los Angeles, USA.

Monitoring Immunosuppressive Mechanisms from Infection

This application note discusses the importance of fast, sensitive, and haze-free imaging for the monitoring of immunosuppression in mouse lung epithelial tissue infected with the Puerto Rico 8…

Studying Actin Cytoskeleton and Microfilament Assembly

This article demonstrates how actin microfilament assemblies can be clearly visualized with superior resolution at the plasma membrane of a cell using a DMi8 S Infinity TIRF High Power imaging…

Exploring the Structure and Life Cycle of Viruses

The SARS-CoV-2 outbreak started in late December 2019 and has since reached a global pandemic, leading to a worldwide battle against COVID-19. The ever-evolving electron microscopy methods offer a…
The THUNDER Imager 3D Cell Culture visualizes an influenza (red) infected primary porcine lung epithelial grown in a multilayer of about 60 µm. The top layer shows cilia (green), which are responsible for mucus transport. Nuclei are stained in blue. Raw image vs. Large Volume Computational Clearing.

Influenza-host Interactions in 3D Specimens

Stefan Finke studies virus-host interactions. It turns out that the ways the virus and host interact are different when comparing results from classical laboratory monolayer cell lines and “close to…

Advanced Quantitative Fluorescence Microscopy to Probe the Molecular Dynamics of Viral Entry

Viral entry into the host cell requires the coordination of many cellular and viral proteins in a precise order. Modern microscopy techniques are now allowing researchers to investigate these…

Coronavirus Replication in Host Cells

In this study, a molecular pore complex, which spans both membranes of SARS-CoV-2/COVID-19 virus-induced cytosolic vesicles and likely plays a role in replication, was visualized.

How Can Immunofluorescence Aid Virology Research?

Modern virology research has become as crucial now as ever before due to the global COVID-19 pandemic. There are many powerful technologies and assays that virologists can apply to their research into…

Upright Fluorescence Microscopy for Virus Replication Studies

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019 and spread over the world quickly. Due to its dramatic impact, researchers are interested in the nature of the…
