HerpeslabNL

The aim of the Herpesvirus Lab is to elucidate the virus-host interactions involved in the immune control and pathogenesis of herpesvirus infections in humans

About our research group/lab

Research

The HerpeslabNL aims to elucidate the virus and host factors involved in the immune control and pathogenesis of the human neurotropic herpes simplex viruses (HSV) and varicella zoster virus (VZV) in their natural host.

A hallmark of these herpesviruses is their ability to establish a lifelong latent infection after primary infection of neurons in sensory ganglia (HSV) or along the entire neuraxis (VZV). Reactivation of latent virus, which occasionally leads to recrudescent disease, is controlled by innate and adaptive immunity. Virus-specific immune responses are commonly beneficial (control of latent infection in sensory neurons), but can also cause detrimental disease affecting the eye (uveitis and keratitis) or the brain (encephalitis and potentially Alzheimer’s disease). The HerpeslabNL has developed a unique infrastructure to acquire human clinical specimens in combination with state-of-the-art methodologies to characterize the virus status (genome, proteome and transcriptome), the virus’ cell tropism, and the innate and adaptive cell types present at the site of infection including their antigen-specificity and effector functions. This enables the identification of the key host and virus factors that determine the clinical outcome of alpha-herpesvirus infections and disease.

The ultimate goal of our research is to develop novel intervention strategies aimed to prevent virus reactivation and herpesvirus-induced pathogenesis.

A finger on the sore cold sore
It was an exciting invention, but it turned out to be poorly executed. A study into the herpes virus shows where things can go wrong with data research.

The cold sore virus is good at playing hide and seek. It has been clear for decades where this virus, herpes simplex (HSV), hides in the body, but how exactly this hiding works remains mysterious. When scientists in the United States reported last year, based on a new technique with large amounts of data, that the virus is hiding in more places than had been known all along, herpes researchers worldwide were immediately interested.
Could this be the reason it is so difficult to make vaccines? Should the common approach to making antivirals change?
"It was a very exciting discovery," says Georges Verjans, lead researcher at Herpeslab NL at the Erasmus MC in Rotterdam. "It just turned out not to be true. The research was poorly conducted." But before Verjans and his colleagues figured this out, there was a tug-of-war over the data and then extensive reanalysis. Afterwards, correcting the incorrect conclusions also turned out to be a major hurdle.

Tim and Anja had shingles: 'The pain was nauseating'

“I have had a few ailments. But this was really miserable. I never want shingles again,” says Rotterdam resident Tim van der Meer (40). The disease left a deep impression on him. Shingles is common: one in three Dutch people will experience it at some point.

When Tim continues to talk, it becomes clear why he never wants to experience the disease again. Even though it didn't even last a week for him. “I couldn't do anything anymore, it hurt so much. Don't lie down, don't sit down. Nothing." Tim couldn't lie down and therefore couldn't sleep. “I was awake for nights.”

Anja van Loo (66) also lay awake a lot when she had shingles. “It hurts so much, it's terrible,” she says. “You just don't know how to lie.” Anja ended up suffering from it for a month.

'Whatever'
Although one in three people will develop shingles at some point in their lives, it is a disease that experts say we don't pay enough attention to. That is why an awareness week is now being organized for the second time to draw attention to the symptoms.
“It is a disease that many people think 'It's okay', but it is really serious. One in ten suffers from a lot of pain and the pain can last for months," says shingles expert and scientific researcher from Erasmus MC Georges Verjans.
Tim had shingles on the right side of his torso, he said. “It looked like a straight piece of cloth from below the chest to the back.” Anja had it on her left side with a few spots on the back.
The worst spot is on the face, Verjans sees. Then you run the risk of infecting the eyes.

Michiel van Gent receives prestigious personal grant (VIDI) from the Dutch Research Council (NWO) to study intrinsic immunity against viral infections of the human nervous system

Seven scientists from Erasmus MC receive a grant from NWO for their research. This will enable the laureates to develop an innovative line of research over the next five years and to further expand their own research group. Six Vidis have been awarded and a subsidy through the Open Technology Programme. Michiel van Gent is one of them.

Viral infections of the nervous system can have very serious consequences, such as permanent neurological damage in newborns, eye infections that can lead to permanent blindness, and inflammation in the brain with fatal outcome.

This research will determine how nerve cells arm themselves against these infections to ensure that harmful viruses cannot enter. A better understanding of these protective processes will provide starting points for the development of new drugs and therapies to combat these viral infections and thus prevent serious disorders of the nervous system.

Awakening a sleeping virus
Dr. W.J.D. (Werner) Ouwendijk (Erasmus medisch centrum)

Herpesviruses are an important cause of severe diseases in humans and animals. Following infection herpesviruses persist in the host as latent virus (i.e., the virus enters a sleep mode). Later in life, the virus can awaken (reactivation) to cause recurrent disease. I will investigate how herpesviruses establish latency and how they can reactivate. Hereto, I will be using varicella-zoster virus (VZV), the cause of chickenpox and shingles, as a model. More insight into these poorly understood processes will be essential for the development of new therapies that prevent reactivation of VZV and possibly other herpesviruses.

Werner Ouwendijk received an ENW XS grant to explore the link between virus infections and Alzheimer’s disease Link (In Dutch)

Impact of virus infections on the development of Alzheimer’s disease.

Dr. W.J.D. (Werner) Ouwendijk (Erasmus medisch centrum)

Infectious diseases increase the risk of getting Alzheimer's disease. How pathogens contribute to Alzheimer's is unclear. In this study, I will use a powerful and innovative technique to analyze the history of virus infections during the lifetime of an individual. By comparing Alzheimer's patients with non-demented controls, I can identify specific viruses or combinations of virus infections that are associated with the development of Alzheimer's disease. This knowledge encourages further research into how these viruses contribute to the disease and can prioritize the development of new antiviral therapies or vaccines.
