Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Persistent TB infection of macrophages puts the brakes on immune engines, study shows

Scientists from Trinity College Dublin have discovered both how TB puts the brakes on our immune engines and how we can kick-start those engines back into gear - providing hope that improved treatment options could soon be on the horizon.

Researchers discover hundreds of novel viruses in insects

New viruses which cause diseases often come from animals. Well-known examples of this are the Zika virus transmitted by mosquitoes, bird flu viruses, as well as the MERS virus which is associated with camels. In order to identify new viral diseases quickly and prevent possible epidemics, DZIF scientists at Charité - Universitätsmedizin Berlin are targeting their search at viruses in animals.

Bile acids help norovirus to infect cells of the small intestine

A new study led by researchers at Baylor College of Medicine and published in the Proceedings of the National Academy of Sciences reveals that human noroviruses, the leading viral cause of foodborne illness and acute diarrhea around the world, infect cells of the small intestine by piggybacking on a normal cellular process called endocytosis that cells use to acquire materials from their environment.

Immunosupressant combination therapy for glioblastoma shows promise

Researchers from the University of Texas have found an immunosuppressing target for the treatment of glioblastoma. In mice studies the team has identified CD73 macrophages which could be used to treat the cancers. The team also performed studies on human tumours to arrive at their conclusions. The study was published in the latest issue of the journal Nature Medicine this week.

Scientists develop 3D atlas of bone marrow to help study blood diseases

The bone marrow, which is the spongy and viscous tissue that fills the bone, is the site of blood cell formation or hematopoiesis. If the bone marrow doesn’t work properly, it can lead to many blood diseases, including leukemia, sickle cell anemia, and lymphoma, among others.

Research shows how the hepatitis D virus copies itself

A team of researchers has discovered how one crucial step occurs in the lifecycle of the hepatitis D virus (HDV), which causes the widespread and hard to treat liver inflammation called hepatitis D. The study, which was published recently in the Journal of Virology, could help develop antiviral therapy to control this disease.
