Primary glia cells from bank vole propagate multiple rodent-adapted scrapie prions

Scientific Reports, 2022
Since the beginning prion research has been largely dependent on animal models for deciphering the disease, drug development or prion detection and quantification. Thereby, ethical as well as cost and labour-saving aspects call for alternatives in vitro.

Replication of cowpox virus in macrophages is dependent on the host range factor p28/N1R

Virology Journal, 2021
Zoonotic orthopoxvirus infections continue to represent a threat to human health. The disease caused by distinct orthopoxviruses differs in terms of symptoms and severity, which may be explained by the unique repertoire of virus factors that modulate the

Dynamic threat processing [PDF]

Journal of Cognitive Neuroscience, 2017
AbstractDuring real-life situations, multiple factors interact dynamically to determine threat level. In the current functional MRI study involving healthy adult human volunteers, we investigated interactions between proximity, direction (approach vs. retreat), and speed during a dynamic threat-of-shock paradigm.

Puumala and Tula Virus Differ in Replication Kinetics and Innate Immune Stimulation in Human Endothelial Cells and Macrophages

Viruses, 2019
Old world hantaviruses cause hemorrhagic fever with renal syndrome (HFRS) upon zoonotic transmission to humans. In Europe, the Puumala virus (PUUV) is the main causative agent of HFRS.
