DUAL BINDING of H5N1 to BOTH AVIAN and HUMAN-TYPE RECEPTORS !!! 🥵🥵🥵

2) The researchers studied this cow flu virus in mice and ferrets, which are common animal models used to understand flu viruses. They found that the cow flu virus can make these animals very sick, and it is able to spread throughout their bodies, including to the eyes ... Image
3) ... mammary glands, and muscles.

Importantly, the researchers also found that this cow flu virus is able to bind to both the bird-like and human-like receptors that flu viruses use to infect cells. Previous bird flu viruses could only bind to the bird-like receptors. Image
4) This ability to bind to human-like receptors means the cow flu virus may be able to more easily infect and spread between people, compared to past bird flu viruses. The virus also showed some ability to spread between ferrets through the air, though not as efficiently ... Image
5) ...as a normal human flu virus.

Overall, these findings suggest this new cow flu virus has acquired concerning features that could make it more likely to cause a human flu pandemic, compared to previous bird flu viruses. Image
6) The researchers emphasize the need for further close study, especially of any human cases that may arise from the current cow outbreak.

Thanks for reading 🙏 Image

NEW KEY STUDY on JN.1, KP.2 and KP.3

biorxiv.org/content/10.110…
Image
2) The study looks at the latest Omicron variants of the SARS-CoV-2 virus, like BA.2.86, JN.1, KP.2, and KP.3. These newer variants have become better at spreading and evading the immune system compared to earlier Omicron versions. Image
3) The researchers used advanced computer simulations and modeling to understand how these Omicron variants interact with the human ACE2 receptor that the virus uses to infect cells, as well as how they interact with different antibodies. Image

ANTIBODIES against OMICRON.
What changed ?

biorxiv.org/content/10.110…
Image
2) The study looked at the antibodies that people's bodies make against the Omicron variant of COVID-19. They found that while Omicron infection causes the body to produce lots of antibodies that target a specific part of the virus called the N-terminal domain (NTD) ... Image
3) ...most of these antibodies are not very effective at neutralizing or blocking the virus.
However, the researchers did identify 5 special antibodies that are extremely good at neutralizing Omicron. These antibodies target a specific region on the NTD called the N1/N2 loop. Image

MITOCHONDRIA in COVID-19: from cellular and molecular perspective

SARS-CoV-2, has a major impact on the mitochondria the powerhouses of our cells. This leads to problems with energy production, the immune system, and cell death. frontiersin.org/journals/physi…
Image
2) SARS-CoV-2 proteins directly interact with and disrupt many mitochondrial proteins. This affects important mitochondrial functions like energy metabolism, calcium regulation, and clearing out damaged mitochondria. Image
3) Parts of the SARS-CoV-2 genetic material are found inside mitochondria, suggesting the virus may use them to replicate. Mutations in mitochondrial DNA are also linked to more severe COVID-19 cases.
Mitochondrial dysfunction contributes to ... Image

SARS-CoV-2 has made a FAUSTIAN BARGAIN with the forces of darkness.
Unlike its viral cousins SARS-CoV and influenza, this novel coronavirus has struck a DEVIL'S DEAL to OBTAIN UNPARALLELED TRANSMISSIBILITY and INFECTIVITY.

2) We had already taken this image of the "pact with the devil" for the virus and the asymptomatics.
In this article, and in the reference study, they hypothesize that a “Faustian bargain”—the trading of increased SARS—CoV2 viral infection ...

People INFECTED with SARS-CoV-2 are SHEDDING not only complete VIRAL PARTICLES, but also VIRAL FRAGMENTS and VIRAL REPLICONS (active virus undergoing replication) !!! 🤦‍♂️

One of the most astonishing studies I have read recently 🎯
biorxiv.org/content/10.110…
Image
2) The study aimed to understand the patterns of SARS-CoV-2 shedding in the respiratory tract of COVID-19 patients. Using sequencing data and single-cell analysis as a reference, the researchers developed a novel algorithm to dissect viral shedding into three main types. Image
3) ▶️ Viral replicons, the intracellular form of SARS-CoV-2 undergoing active replication and transcription. ▶️ Viral particles, the intact extracellular viral particles released after the viral life cycle is complete.
▶️ Viral fragments, the incomplete and deactivated viral RNA Image

The SUPERSPREADERS (18% of the population) ACCOUNTED for :

40%, 60% or 80% of INFECTION DISTRIBUTION ? pnas.org/doi/10.1073/pn…
Image
In this study they showed that exhaled aerosol particles vary greatly between individuals, with 18% of people accounting for 80% of total particles. Particle size distribution shifts towards smaller particles during peak infection, which highlights the airborne transmission risk. Image
3) The findings suggested that the capacity of airway lining mucus to resist breakup on breathing varies significantly between individuals, with a trend to increasing with the advance of COVID-19 infection and higher BMI-years. Image
