Virus News and Research

RSS

A virus is a microscopic infectious agent that can reproduce only inside a host cell. Viruses infect all types of organisms: from animals and plants, to bacteria and archaea. Since the initial discovery of tobacco mosaic virus by Martinus Beijerinck in 1898, more than 5,000 types of virus have been described in detail, although most types of virus remain undiscovered. Viruses are ubiquitous, as they are found in almost every ecosystem on Earth, and are the most abundant type of biological entity on the planet. The study of viruses is known as virology, and is a branch of microbiology.

Gene Recognition of CRISPR-Cas Visualized With New Method

A novel technique has been devised by researchers from the University of Leipzig and the University of Vilnius in Lithuania to monitor the smallest twists and torques of molecules in milliseconds.

Immune Deficits in Space are Temporary

An increase in proof has been found that astronauts are highly vulnerable to infections while in space. For instance, astronauts on board the International Space Station (ISS) generally suffer from skin rashes, and also respiratory and non-respiratory diseases.

Influenza A Viruses Use "Tactical Strikes" to Hijack Host Cells

Influenza A is one of two influenza viruses that fuel costly annual flu seasons and is a near constant threat to humans and many other animals. It’s also responsible for occasional pandemics that, like the one in 1918, leave millions dead and wreak havoc on health systems and wider society.

Cells with “Jumping Genes” Self-Destruct in the Early Stages of Development

A previously unknown type of cell that self-destructs within days of forming as part of a quality control procedure to protect the growing fetus has been found by researchers studying gene activity data of the early human embryo.

Microglial Cells Serve as a Stable Viral Reservoir for Latent HIV

Human immunodeficiency virus-1 (HIV) introduces a copy of its DNA into human immune cells as part of its life cycle. Some of these newly infected immune cells can subsequently enter an inactive, latent state for an extended length of time, which is known as HIV latency.

Virus Plays Important Role in Treating Glioblastoma

A potential advancement in the treatment of glioblastoma was noted by Howard Colman, MD, PhD, the Jon M. Huntsman Presidential Professor of Neuro-Oncology and co-leader of the Neurologic Cancers Disease Center and the Experimental Therapeutics CCSG program at Huntsman Cancer Institute, in a recently published manuscript.
