Our LIVES would be very DIFFERENT, if we could have CAMEL NOSES ! π€π
"Resistance to SARS-CoV-2 infection in camelid nasal organoids is associated with lack of ACE2 expression" nature.com/articles/s4429β¦
2) The study investigated whether camels and other camelids can be infected by SARS-CoV-2, the virus that causes COVID-19. The researchers used special 3D models of camelid nasal cells to test this.
3) They found that the camelid nasal cells were resistant to infection by different variants of SARS-CoV-2, including the Omicron variant. However, these cells could be easily infected by another coronavirus, MERS-CoV, which is known to infect camels.
4) The reason for this difference is that camelids lack the ACE2 protein, which SARS-CoV-2 uses to enter human cells. Instead, camelid cells express a different protein called DPP4, which allows MERS-CoV to infect them.
5) These results suggest that camels and other camelids are unlikely to act as reservoirs for SARS-CoV-2, unlike some other animal species. The study provides important insights into the factors that determine which animals can be infected by different coronaviruses.

2) Viruses are not living things. They are tiny particles that can only make copies of themselves inside the cells of living things, like humans. When a virus makes copies of itself, it doesn't always make perfect copies.
3) Sometimes, little mistakes happen, and the new virus has a small change, or mutation, in its genes.
Most of the time, these mutations don't do anything useful for the virus. But every now and then, a mutation might happen that makes the virus better at infecting people.
2) This study looks at the risks of COVID-19 for people traveling to space.
Space travel is becoming more common, with over 600 people having gone to space. But COVID-19 could be a big problem for astronauts in the unique environment of space.
3) The study aims to understand how COVID-19 might behave differently in space compared to on Earth.
The researchers reviewed studies on other airborne diseases in space. They found that some diseases, like Epstein-Barr virus and Serratia bacteria ...
From Lung Damage to Gut Dysbiosis:
The Lasting Implications of SARS-CoV-2 Variant-Specific Microbiome Changes (From Wuhan strain to Omicron) labanimres.biomedcentral.com/articles/10.11β¦
2) The Wuhan strain of SARS-CoV-2 caused serious damage to the lungs of infected mice. The mice had a very high chance of dying from this strain. The researchers also looked at the bacteria in the lungs and guts of the infected mice.
3) The Wuhan strain increased harmful bacteria like E. coli in the lungs. This can make the lungs more prone to other infections.
The Omicron variant caused different changes in the gut bacteria of the mice. It increased certain bacteria linked to inflammation in the gut.
What are GAMMA CORONAVIRUSES ?
And why did we decide to talk about it?
2) A brief reminder :
βΆοΈ SARS-CoV-2 belongs to the family Coronaviridae, is classified as a coronavirus and is responsible for COVID-19
βΆοΈ Bird Flu refers to various strains of the influenza virus, particularly those in the Orthomyxoviridae family including H5N1 and H7N9.
3) βΆοΈ Gammacoronavirus belongs to the family Coronaviridae like SARS-COV-2.
Some notable gammacoronaviruses include:
- Infectious Bronchitis Virus (IBV): A major pathogen in poultry responsible for respiratory disease and reduced egg production.
A TREATMENT that Could Finally END Long COVID Suffering ?
This isn't the first time a treatment has been announced, and as millions continue to struggle with long Covid, we need to remain both cautious and hopeful π€
2) Researchers at WEHI announced that they discovered a new drug that can stop long COVID symptoms in mice. This drug is more effective than the current top treatment, Paxlovid, for both long COVID and acute COVID cases.
3) They focused on a specific protein called PLpro that other treatments haven't targeted well. This breakthrough could lead to new medicines for long COVID, a condition where people continue to feel sick long after their COVID-19 infection.
2) Long COVID is a complex condition that affects many people after they have had COVID-19. It can cause a wide range of symptoms that last for a long time. There are not many clear guidelines on how to diagnose and treat Long COVID.
3) An international group of 179 experts from 28 countries worked together to provide recommendations on Long COVID. They used a survey method called the Delphi process to reach consensus on important issues.
