Researchers discover how Rift Valley fever virus enters cells

Researchers discover how Rift Valley fever virus enters cells

Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hundreds of human cases and dozens of deaths. Rift Valley fever, for which there is no specific treatment, has been …

Comparison of recombinant SARS-CoV-2 receptor binding domain produced in mammalian, insect, and bacterial cells

Comparison of recombinant SARS-CoV-2 receptor binding domain produced in mammalian, insect, and bacterial cells

The spike (S) protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) plays a critical role in receptor recognition and host-cell entry. Thus, major efforts to characterize and reproduce this protein in its truest form have been underway since the inception of the coronavirus disease 2019 (COVID-19) pandemic to support the development of adequate …

Researchers develop new method to track the development of cancer cells

Researchers develop new method to track the development of cancer cells

Changes in individual cancer cells over time may explain why brain tumours develop so differently, and why some cancer cells are resistant to certain treatments. To track the development of cancer cells, researchers at Uppsala University have devised a new method that, in the long term, may make it easier to develop new, effective drug …

New automated computer program can accurately count micronuclei in cells

New automated computer program can accurately count micronuclei in cells

Micronuclei, which are small nucleus-like structures within cells, are commonly associated with tumors. Now, researchers from Tsukuba, Japan have developed an automated computer program that can accurately and reproducibly count these structures from microscope images, which will increase the speed and accuracy of micronuclei research. In a recently published study, researchers from the University of …

SARS-CoV-2 may have consequences to host cells beyond evoking an immune response

Recent data indicates that individuals are experiencing coronavirus disease 2019 (COVID-19) symptoms long after clearing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which suggests the virus has profound consequences to host cells. Study: SARS-CoV-2 triggers DNA damage response in Vero E6 cells. Image Credit: Festa/ Shutterstock RNA viruses, such as SAR-CoV-2, are renowned for …

Functional impairment of HIV-specific T cells precedes aborted virus control

Functional impairment of HIV-specific T cells precedes aborted virus control

HIV is a master of evading the immune system, using a variety of methods to prevent the body from being able to find and kill it. The vast majority of people living with HIV require daily medication to suppress the virus and therefore prevent the development of AIDS. But for a small subset of people, …
