Hydroxychloroquine blocks SARS-CoV-2 entry into the endocytic pathway in mammalian cell culture
Nature ^

Posted on 09/28/2022 2:15:17 PM PDT by NoLibZone

Hydroxychloroquine (HCQ), a drug used to treat lupus and malaria, was proposed as a treatment for SARS-coronavirus-2 (SARS-CoV-2) infection, albeit with controversy.

In vitro, HCQ effectively inhibits viral entry, but its use in the clinic has been hampered by conflicting results.

A better understanding of HCQ’s mechanism of actions in vitro is needed. Recently, anesthetics were shown to disrupt ordered clusters of monosialotetrahexosylganglioside1 (GM1) lipid. These same lipid clusters recruit the SARS-CoV-2 surface receptor angiotensin converting enzyme 2 (ACE2) to endocytic lipids, away from phosphatidylinositol 4,5 bisphosphate (PIP2) clusters. Here we employed super-resolution imaging of cultured mammalian cells (VeroE6, A549, H1793, and HEK293T) to show HCQ directly perturbs clustering of ACE2 receptor with both endocytic lipids and PIP2 clusters.

In elevated (high) cholesterol, HCQ moves ACE2 nanoscopic distances away from endocytic lipids. In cells with resting (low) cholesterol, ACE2 primarily associates with PIP2 clusters, and HCQ moves ACE2 away from PIP2 clusters—erythromycin has a similar effect. We conclude HCQ inhibits viral entry through two distinct mechanisms in high and low tissue cholesterol and does so prior to inhibiting cathepsin-L. HCQ clinical trials and animal studies will need to account for tissue cholesterol levels when evaluating dosing and efficacy.

“Nature” is super respected.

I’m surprised they allowed this to be published, but, perhaps, Sars is water under the bridge and legitimate work can now be spoken to.

Well duh... quite a few doctors have been saying that for 2 years +... and getting threatened with losing their medical license for doing so (or for prescribing it).

Here's Yale's Prof. Harvey Risch, MD, PhD, Yale School of Public Health:

https://academic.oup.com/aje/article/190/7/1435/6038970?login=false

The largest nonrandomized but controlled outpatient trial, of HCQ + zinc versus zinc alone, conducted as a national study in the modernized health-care system across the entire country of Saudi Arabia and including nearly 8,000 patients, showed a dramatic and very significant 4–5-fold mortality reduction in the HCQ + zinc arm (7). Worldwide, countries using HCQ or ivermectin as the basis component for early outpatient treatment have per capita COVID-19 mortality proportions 4-fold or more lower than that of the United States (8, 9).

Doesn’t make any difference now. All the shots and boosters have been taken, people are brainwashed to take more, and now they just don’t care. All ready to start the next plandemic ... what, is that ebola on the rise, will Ivermectin or HCQ not work against it.

Agree!!

They KNEW HCQ was an excellent preventative and treatment.

Blood is definitely on their evil hands.

And ... the prolonged pandemic emergency allowed many changes to election protocols in 2020 resulting in a Biden “win”. The USA and much of the world is paying for that now.

Even the beagles knew Fauci was lying when he said he was doing this for the greater good.

Here's the "controversies" over it:

* Trump spoke about its possible utility
* it's out of patent, so no money to be made from it by Pharma
* it didn't help Fauci cover up his involvement with the Wuhan Lab
* it's not mRNA, so doesn't involve GreatReset genetic engineering.

Other than that, pretty good treatment for the Woo.
