How chikungunya virus may cause chronic joint pain

A new method for permanently marking cells infected with chikungunya virus could reveal how the virus continues to cause joint pain for months to years after the initial infection, according to a study published August 29 in the open-access journal PLOS Pathogens by Deborah Lenschow of Washington University School of Medicine in St. Louis, and colleagues. According to the authors, […]

How viruses outsmart their host cells: Scientists decipher protein structure after more than fifty years of research

Viruses depend on host cells for replication, but how does a virus induce its host to transcribe its own genetic information alongside that of the virus, thus producing daughter viruses? For decades, researchers have been studying a type of bacteriophage known as ‘lambda’ to try and find an answer to this question. Using high-resolution cryo-electron microscopy, a research group from […]

Charcoal-based drug delivery system improves efficacy of common herpes drug

A study led by researchers from the University of Illinois at Chicago has found that combining acyclovir — a commonly prescribed topical herpes medication — with particles of activated carbon improves efficacy of the drug. This new approach allows for less frequent dosing and overall course of treatment while providing some protection from infection by the virus as well, opening […]

Newly developed approach shows promise in silencing HIV infection

Researchers from The University of Texas Medical Branch at Galveston have discovered a new potential medication that works with an HIV-infected person’s own body to further suppress the ever present but silent virus that available HIV treatments are unable to combat. Although the potential new drug could complement the current HIV anti-retroviral therapy (ART) medications, it may also be possible […]

Light pollution may be increasing West Nile virus spillover from wild birds

We’re in the midst of summertime mosquito bite season and cities across the country are reporting a heightened number of West Nile Virus (WNV) cases. The house sparrow is one of the most common carriers of WNV in urban areas. Mosquitos feed off the infected birds and spread the virus to humans. New research finds house sparrows exposed to artificial […]

High-risk pregnancy: The interferon effect: Discovery of a cellular mechanism involved in abnormal placental development during some high-risk pregnancies

High-risk pregnancies occur frequently and may be caused by various factors. It is estimated that 10 to 20% of pregnant women miscarry during their first trimester of pregnancy. Slow fetal growth may also arise as a result of maternal infection with certain microbes, parasites or viruses (such as toxoplasmosis or infection with rubella virus, cytomegalovirus, herpes or Zika) or because […]

Deadly tick-borne virus cured with experimental flu drug, in mice: Bourbon virus has sickened people in Kansas, Missouri, Oklahoma

Only a few cases of the newly discovered Bourbon virus have been reported, and two of them ended in death, partly because no specific treatments are available for the tick-borne illness. Now, researchers at Washington University School of Medicine in St. Louis have identified an experimental antiviral drug that cures mice infected with the potentially lethal virus. The drug, favipiravir, […]

Probiotic-derived molecule may suppress fatal brain inflammation, preclinical study finds: Scientists explore how swallowing a ‘bacterial envelope molecule’ may prime your body to fend off viral infections

The existence of certain microorganisms in your gut may bolster the immune system’s ability to fend off a herpes viral attack that can cause fatal brain inflammation, reports a new City of Hope-led study. Researchers say the findings are the first to suggest that an envelope molecule from a bacterium called Bacteroides fragilis (B. fragilis) might be useful against viral […]

‘Test and Treat’ reduces new HIV infections by a third in southern Africa communities

New HIV infections in southern Africa could be reduced substantially by offering entire communities voluntary HIV testing, and immediately referring those who test positive for HIV treatment in line with local guidelines, according to new research presented at the Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, USA today. The HPTN071 (PopART) trial found that new HIV infections were […]

Pan-filovirus T-cell vaccine protects mice from Ebola and Marburg

Vaccines that induce protective T-cell responses could protect against members across the filovirus family, according to a study published February 28 in the open-access journal PLOS Pathogens by Tomáš Hanke of the University of Oxford, Bette Korber of the Los Alamos National Laboratory, and colleagues. Developing an effective vaccine against filovirus outbreaks is an important public health aim. Vaccine candidates […]
