The FUNNEL of ESCAPE : Unlocking the Secrets of SARS-CoV-2 Survival !
An explanation for Kids 👩❤️👨based on this recent study :
"Constrained Evolutionary Funnels Shape Viral Immune Escape" biorxiv.org/content/10.110…
2) In this study, scientists are trying to understand how tricky viruses, like the one that causes COVID-19, try to escape from our body's defenses.
**The Virus and Our Immune System:**
- Viruses are sneaky and always want to find new ways to avoid being caught ...
3) ... by our immune system (the body's defense system). Think of it like a character in a game that needs to avoid traps and heroes trying to catch them.
4) **The Funnel Escape:**
- When the virus tries to escape, it doesn’t have unlimited options. Instead, it has to follow certain paths that are more like a funnel. Imagine a funnel used in cooking: it starts wide at the top but narrows down.
5) The virus has many possible ways to change (or mutate), but only a few safe paths that won't break it (like how the cooking funnel helps pour without spilling).
6) **Why Only a Few Paths?**
- The scientists discovered that as the virus changes, it has to keep its structure intact, like a character that can’t lose its health points while trying to dodge obstacles. If the virus changes too much, it can’t survive.
7) **Learning from Experience:**
- By studying how the virus has changed, the scientists created a model that predicts how the virus might escape in the future. They looked at many examples to see which changes helped the virus survive and dodge our immune defenses.
8) **The Power of Antibodies:**
- Antibodies are like special power-ups in the game that help our immune system fight the virus. The study found that using different combinations of these power-ups can make it harder for the virus to escape.
9) It's like having a team of heroes that covers all the escape routes, making it tougher for the virus to find a safe path.
6. **Why This Matters:**
- Knowing these escape funnels helps scientists predict how the virus might change over time and why some treatments work ...
10).. better than others. It’s like figuring out the best strategies to win the game against the virus!
So, in short, this study helps us understand how viruses try to escape our immune system and how we can use that knowledge to create better defenses against them!
Thanks 😊

NIPAH VIRUS
Jumping to conclusions during outbreaks only fuels panic and misunderstanding; NOT EVERY VIRUS OUTBREAK is a PANDEMIC.
We raised the alarm about Nipah in 2023, but it’s essential not to confuse an epidemic related to this virus, ...
2) ...like the one in India, with a pandemic risk or a situation like COVID-19.
Nipah virus is transmitted primarily from animals, especially bats, to humans. It spreads through direct contact with infected animals, their secretions, or contaminated foods.
3) Human-to-human transmission occurs only through close contact, such as touching or caring for an infected person, as well as sharing fluids like saliva or blood.
We cannot equate a virus transmitted through fluids with a respiratory virus like SARS-CoV-2.
"70% to 90% of our CELLS are completely RENEWED in less than 5 YEARS!
So If we’re mostly "New", why are so many still struggling with SARS-CoV-2?
We will tackle this question, which is more complex than it seems, in several posts.
2) First, let's say a few words about cell renewal.
70% to 90% of our cells are renewed over time. This turnover occurs in various cell types, including skin, blood, and immune cells, allowing the body to replace damaged or aged cells. sciencefocus.com/the-human-body…
3) For instance, red blood cells have a lifespan of about 120 days, while skin cells regenerate every few weeks.
Even with significant cell renewal, aging persists due to changes in our DNA. sciencefocus.com/the-human-body…
2) Co-infection occurs when a person is infected by more than one virus at the same time. This can lead to interesting and sometimes complex interactions between the viruses
3) In one study about SARS-CoV-2, researchers found that when different versions of this virus infect the same person, they can mix their genetic material through a process called recombination. This means that the new version of the virus can have traits from both parent viruses
For more than three years, we have been emphasizing that the envelope protein is an essential component and that we cannot limit our focus to just the spike protein. We are now uncovering its role in long COVID.
3) The Envelope (E) protein of SARS-CoV-2 plays a crucial role for several reasons:
▶️ Virus Assembly and Release: The E protein is essential for the virus's assembly and budding from infected cells, contributing to its stability and infectivity.
In 2022, COVID-19 was the second leading cause of death globally, with the repercussions of the virus far from over. The lasting impact of the pandemic continues to affect lives around the world.
Recent research may have identified a key factor contributing to long COVID: microscopic clots intertwined with immune system debris in the blood. These unusual structures were found to be nearly 20 times more prevalent ...
2) ...in long COVID patients compared to healthy individuals. The clots, associated with neutrophil extracellular traps (NETs), suggest a potential biological marker for persistent symptoms.
3) These microclots could impede blood flow in small vessels, leading to issues like brain fog, fatigue, and shortness of breath.
