Oncolytic Viroimmunotherapy Improved by Enhanced Cytokine Transgene Expression 1024 575 Lauren Dembeck

Researchers were able to suppress in vivo tumor growth with an oncolytic virus by enhancing the production of the cytokine interleukin-12 in the tumors. Malignant peripheral nerve sheath tumors (MPNSTs) are rare, aggressive sarcomas that exhibit resistance to non-surgical treatment and have high rates of metastasis and relapse. The prognosis for MPNSTs is poor, with…

Investigators from Nationwide Children’s Hospital and The Ohio State University modified the measles and mumps viruses from the measles-mumps-rubella (MMR) vaccine to deliver three SARS-CoV-2 spike protein variants to the respiratory tract as an effective vaccine candidate. “We’re calling this a trivalent vaccine because it protects against three different variants of SARS-CoV-2,” says Mark Peeples,…

SARS-CoV-2 RNA in the Blood is Associated With Worse Outcomes in Kids
SARS-CoV-2 RNA in the Blood is Associated With Worse Outcomes in Kids 1024 575 Katie Brind'Amour, PhD, MS, CHES

Researchers have identified a risk factor for more severe illness in children with COVID-19: detectable levels of SARS-CoV-2 RNA circulating in the blood. Children with detectable SARS-CoV-2 RNA in the blood, called RNAemia, were more likely to require oxygen and be admitted to the intensive care unit than children with COVID-19 who did not have…

The interaction between the bacteria and respiratory syncytial virus (RSV) appears to be synergistic. Researchers are now working to understand the underlying biological mechanisms. Researchers at Nationwide Children’s Hospital have discovered that codetection of Haemophilus influenzae and Streptococcus pneumoniae in the upper respiratory tract of previously healthy infants with RSV infection was independently associated with…

Understanding Immune Responses to Build a Better Vaccine
Understanding Immune Responses to Build a Better Vaccine 1024 606 Abbie Miller

Researchers have used studies of respiratory syncytial virus and infant immune responses to develop a promising vaccine candidate. Respiratory syncytial virus (RSV) is an incredibly common yet potentially deadly pathogen. Almost everyone becomes infected with RSV during their first three years of life, but for certain populations — infants and elderly or immunocompromised people —…

The new vaccine candidate takes advantage of the long and successful history of the measles vaccine. A team of researchers from The Ohio State University and Nationwide Children’s have built a novel vaccine candidate against SARS-CoV-2. The candidate, published in Proceedings of the National Academy of Sciences (PNAS), used the measles vaccine as a vector…

Systems Analyses Unravel Clinical Phenotypes in Infants with Respiratory Syncytial Virus Infection
Systems Analyses Unravel Clinical Phenotypes in Infants with Respiratory Syncytial Virus Infection 1024 575 Mary Bates, PhD

RSV disease severity is influenced by innate immune responses, viral loads and patient age. Respiratory syncytial virus (RSV) is a leading cause of hospitalization in children, although most cases result in mild disease. To develop effective antivirals and vaccines, a better understanding of the different clinical, immunologic and virologic factors present in infants with mild…

What Could COVID-19 Mean for Pediatrics?
What Could COVID-19 Mean for Pediatrics? 1024 683 Abbie Miller

As COVID-19 spreads across the globe, experts are digging into the data and establishing protocols to better understand the illness in the context of pediatrics. As COVID-19, the illness caused by a novel coronavirus, has reached pandemic status, life has changed dramatically. At Nationwide Children’s Hospital, the halls are uncharacteristically quiet as a “stay at…

Could Restoring CD4+ T Cell Immunity Help Control Hepatitis C Infection?
Could Restoring CD4+ T Cell Immunity Help Control Hepatitis C Infection? 1024 683 Kevin Mayhood

Following childbirth, some women with chronic infection experienced a recovery of HCV-specific CD4+ T cells and a reduction in viral replication. In chronic hepatitis C (HCV) infections, CD4+ T cells that recognize the virus have been so hard to detect, some researchers thought they may be completely depleted. But research led by investigators at Nationwide Children’s…

Link Found Between Respiratory Syncytial Virus Infection and Asthma 800 533 Mary Bates, PhD

RSV infection early in life increases risk of subsequent wheezing or asthma. Respiratory syncytial virus (RSV) is the leading cause of hospitalization in infants all over the world. It can lead to serious acute infections, and new research from Nationwide Children’s shows RSV infection can also have long-term health consequences. In a new study, researchers…

Understanding viral load dynamics can help inform treatment decisions Respiratory syncytial virus (RSV) lower respiratory tract infection is a leading cause of hospitalization and mortality in infants worldwide, but a licensed RSV vaccine has not yet been developed, in part due to the incomplete understanding of RSV pathogenesis. While investigating the relationship between RSV viral…

Novel Metric Predicts Severity of Community-Acquired Pneumonia
Novel Metric Predicts Severity of Community-Acquired Pneumonia 150 150 Rachael Hardison

Researchers utilize a biomarker to predict disease severity during early stages of pneumonia. Community-acquired pneumonia (CAP) is a leading cause of hospitalization and mortality in children. Each year, 4 percent of children under 5 years of age will develop CAP in industrialized countries. Although pneumonia is common, diagnosing and treating it remains a challenge for…

Vaccine Enables Model to Clear Hepatitis C Virus and Prevent Persistence 150 150 Kevin Mayhood

Scientists are conceptualizing an effective HCV vaccine using a new animal model. Hepatitis C virus (HCV) subverts responses of immune cells, resulting in chronic infection in more than 71 million people worldwide. The virus causes 1.79 million new infections and 399,000 deaths worldwide annually. Antivrials can cure the disease but are unaffordable or not available…

Researchers find a related protein cloaking the virus has differences that could become treatment targets. A protein that doctors use as a marker of hepatitis E virus (HEV) infection is not directly involved in the virus lifecycle but acts as a decoy drawing away antibodies, helping HEV evade the immune system and thrive, researchers in…

For decades, complete blood cell counts have been the go-to way to identify babies at high risk for serious bacterial infections. But recent research shows the popular lab test isn’t as useful as everyone thought. The Pediatric Emergency Care Applied Research Network (PECARN) has worked for the past decade to both evaluate new technologies and…

A team of researchers finds that Hepatitis E behaves uniquely compared other hepatitis viruses and hopes to pave the way for future investigation. Hepatitis E virus (HEV) is one of five known human hepatitis viruses and infects approximately 20 million people annually. HEV causes significant morbidity and mortality around the world, causing acute hepatitis in…
