Virus News and Research RSS Feed - Virus News and Research

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.
Combination of different drugs could improve effect of immunotherapy on skin cancer

Combination of different drugs could improve effect of immunotherapy on skin cancer

The results of studies involving researchers from the MedUni Vienna and Vienna General Hospital Comprehensive Cancer Center show that the effect of immunotherapy on malignant melanoma (black skin cancer) can be improved by combining it with other cancer treatments. [More]
New project clarifies molecular processes involved in hidden HIV reservoir

New project clarifies molecular processes involved in hidden HIV reservoir

In spite of ever more effective therapies, HIV keeps managing to survive in the body. A comprehensive project conducted by the Austrian Science Fund FWF has clarified the molecular processes which contribute to this effect. [More]
Super-resolution imaging of biological specimens: an interview with Dr. Manasa Gudheti

Super-resolution imaging of biological specimens: an interview with Dr. Manasa Gudheti

Traditional light microscopy techniques such as confocal and wide-field are diffraction-limited in resolution, which is about 200 nm laterally (in xy) and 500 to 600 nm axially (in z). Features that are closer than the diffraction limit will appear blurred in the image. [More]

UNC secures $18 million NIH funding to form iTech for facilitating HIV research studies

People under the age of 30 account for the majority, or 40 percent, of new HIV infections in the United States. [More]
Broadly neutralizing HIV antibodies open new avenues for development of effective vaccine

Broadly neutralizing HIV antibodies open new avenues for development of effective vaccine

A small number of people infected with HIV produce antibodies with an amazing effect: Not only are the antibodies directed against the own virus strain, but also against different sub-types of HIV that circulate worldwide. [More]
Research shows degenerative diseases affecting the retina may be treatable with gene therapy

Research shows degenerative diseases affecting the retina may be treatable with gene therapy

Researchers have demonstrated the ability to deliver a fully functional copy of the CLN3 gene to stem cells of patients with juvenile NCL, an inherited neurodegenerative disease in which a mutation in the CLN3 gene causes early-onset severe central vision loss. [More]

Solid-state NMR in structural biology: an interview with Professor Tatyana Polenova

Solid-state NMR in structural biology: an interview with Professor Tatyana Polenova

My research lab studies several classes of systems. We are mostly interested in looking at large protein assemblies to understand their structure, dynamics and how their properties relate to their malfunction in disease. [More]
Lund University stem cell researcher awarded Fernström prize for study on repairing damaged brain

Lund University stem cell researcher awarded Fernström prize for study on repairing damaged brain

Is it possible to convert a patient’s own skin cells into functioning nerve cells? Or insert healthy genes to reprogram the cells of a damaged brain? Stem cell researcher Malin Parmar at Lund University in Sweden is studying these types of issues, in close collaboration with clinical researchers. [More]
First case-control study examines link between microcephaly and in utero Zika virus infection

First case-control study examines link between microcephaly and in utero Zika virus infection

The relation between Zika virus and microcephaly is widely assumed to be causal because of strong evidence of an association. However, evidence so far comes from case reports, case series, modelling studies, and preliminary reports from cohort studies – none of which have included appropriate control groups. [More]
New global health strategy aims to eliminate HCV as global public health threat by 2030

New global health strategy aims to eliminate HCV as global public health threat by 2030

Chronic infection by the hepatitis C virus (HCV) proved fatal for over 700,000 people worldwide in 2013, mainly as a result of liver damage. Although information on the epidemiology of transmission and infection is sparse, recent estimates put the global prevalence of HCV infection at 130-150 million people. [More]
