#### Title: Understanding Long COVID: How the SARS-CoV-2 Spike Protein Could Affect Our Brain Health

Recent research from Helmholtz Munich and Ludwig-Maximilians-Universität (LMU) has shed light on a critical aspect of Long COVID, particularly its neurological symptoms. As more people recover from COVID-19, it becomes increasingly apparent that some patients continue to suffer long-term effects despite having seemingly mild infections. These lingering issues can include cognitive difficulties, fatigue, anxiety, and depression—collectively referred to as “Long COVID.”

The central focus of this new study is the behavior of the SARS-CoV-2 spike protein after infection. The spike protein is a crucial part of the virus responsible for entering human cells. Researchers have discovered that even after a person recovers from the acute phase of COVID-19 and clears the virus from their body, remnants of this spike protein may persist in various tissues for much longer than previously thought.

**What did researchers find?**

In their investigation, scientists examined brain tissue samples taken from individuals who had suffered from Long COVID symptoms. They observed an accumulation of spike proteins in these samples. This discovery leads researchers to hypothesize that these proteins may disrupt normal brain function over time.

The implications are significant because they provide insight into how lingering neurological effects occur post-infection. By understanding this mechanism better, medical professionals can develop targeted treatment strategies aimed at alleviating symptoms experienced by those with Long COVID.

**Why do these findings matter?**

Long-term complications following viral infections are not new; however, they have rarely been studied as comprehensively as those stemming from SARS-CoV-2 – especially with respect to potential residual viral components like proteins causing persistent inflammation or other adverse reactions in specific organs such as the brain.

As our understanding grows concerning how viruses interact with our body—and why certain symptoms manifest long after initial recovery—the possibility emerges for advanced therapeutic approaches tailored specifically towards managing Long COVID’s diverse impacts on mental health and cognition.

**Comparing Similar Cases**

Interestingly enough, similar mechanisms have been observed in other viral infections like HIV or Epstein-Barr Virus (EBV), which also demonstrate prolonged persistence within tissues leading to enduring health concerns long after acute illness has resolved.

However; until now there was insufficient correlation established between structurally remaining spikes linked directly attributable neurological disturbances attributed solely through contraction

ERC Consolidator Grant für Georg Winter gibt rasant wachsendem Forschungsfeld weiteren Auftrieb

Maßgeschneiderte kleine Moleküle, die sich an Krebs verursachende Proteine heften und Tumorzellen dadurch unschädlich machen – das ist Georg Winters Spezialgebiet, in dem sich der Forschungsgruppenleiter am CeMM der ÖAW als weltweit führender Experten etabliert hat. Sein neuestes ERC CoG Projekt GENEomorph hebt seine Forschung auf eine neue Ebene: Anstatt Krebsproteine wie bisher für die zelluläre Müllabfuhr zu markieren, nimmt Winter mit seinen Design-Molekülen nun sogenannte Transkriptionsfaktoren ins Visier, ein vielversprechender Weg für neue Medikamente. Das sieht auch der Europäische Forschungsrat ERC so: Er fördert dieses Projekt in den nächsten fünf Jahren mit 1,9 Millionen Euro.
