2)"Therapeutic targets and interventional strategies in COVID-19: mechanisms and clinical studies"
Current treatment strategies for COVID-19 can be classified into "target virus" and "target host" categories. Repurposing existing drugs, emerging drugs .. nature.com/articles/s4139โฆ
3) ...and promising potential targets fall under these categories.
For the host, ACE2 receptor, TMPRSS2 protease, inflammatory cytokines and their pathways, CD147, and HMGB1 are potential therapeutic targets based on their roles in viral entry/pathogenesis/excessive inflammation.
4) Future directions include focusing on more promising targets, strengthening multi-disciplinary cooperation, addressing gaps between preclinical/clinical research, and monitoring viral mutations. A combination of antiviral and immunomodulatory therapies may be most effective.
7) Potential therapeutic targets include viral proteins like spike, protease, RNA polymerase, and host proteins involved in viral entry/ immunopathology. Various agents have shown anti-SARS-CoV-2 activity in preclinical/clinical studies, but most require further development.
8) Treatment strategies aim to administer antiviral drugs early to outpatients, while immunomodulators may benefit severely ill inpatients. Treating long COVID remains challenging due to its unclear mechanisms. Development of pan-coronavirus therapies is another priority area.
9) Overall, while progress has been made, more convenient and broadly effective antiviral therapies are still needed to effectively tackle COVID-19 and future coronavirus outbreaks, including those targeting key viral proteins and able to counter emerging variants.
10) Thanks for reading ๐ and have a wonderful sunday ๐ค

IS SARS-CoV-2 BECOMING "INVISIBLE"? The Hidden Truth Behind the Pandemic
As the world strives to move past the COVID-19 pandemic, a troubling narrative has emerged: the perception that SARS-CoV-2 is becoming "invisible."
2) Governments and communities are eager to return to normalcy, leading to a tendency to downplay the virus's severity. Reports of new infections and long COVID cases have been totally minimized, creating a false sense of security ...
3) ...that the virus is no longer a significant threat. However, this perception is not only a matter of public sentiment. The virus itself has evolved, most notably with the emergence of the Omicron variant. Recent research reveals that Omicron exhibits a remarkable ability ...
2) This research shows that SARS-CoV-2, the virus that causes COVID-19, stops infected cells from dying. Normally, when cells die, it helps stop viruses from spreading. By keeping these cells alive longer, SARS-CoV-2 allows itself to multiply and also helps other viruses ...
3) ... like influenza A, grow more easily.
When someone has both SARS-CoV-2 and influenza A, the two viruses can make a person much sicker. The immune system gets overwhelmed, leading to more inflammation and damage to the lungs.
ENTROPY UNLEASHED:
How Viral Protein Interactions Drive Coronavirus Adaptation in Bats and Humans
Entropy, in a general sense, refers to the level of disorder or randomness in a system. biorxiv.org/content/10.110โฆ
2) When we talk about protein interactions and viral behavior, entropy can be viewed as a measure of how complex and varied these interactions are.
In the context of the study about coronavirus interactions in bat and human cells, here's a simplified breakdown.
3) **Complex Interactions**: The study identifies how proteins from the coronavirus interact with host cells (both bats and humans). These interactions can be highly ordered (low entropy) or more chaotic (high entropy).
Patients care most about how COVID-19 affects their health and daily life, including for those with long COVID. Scientists focus on understanding the virus to find better treatments. Both views are important for dealing with the pandemic.
2) I'm bringing up this topic because, after talking so much about the disease, its long-term effects, treatments, and vaccines, many people have forgotten that we are dealing with the most dangerous virus humanity has ever faced.
Organelles provide the possibility for the virus to organize its RNA in PROTECTED structures, concentrate REPLICATION machinery ... nature.com/articles/s4146โฆ
