Discussions emphasize the scientific consensus that chloroquine does not inhibit SARS-CoV-2 in human lung cells, citing peer-reviewed research from sources like Nature, with posts highlighting that this evidence may end the long-standing debate about its efficacy. The tone is analytical and conclusive, reflecting the importance of these findings for public health and treatment strategies.
AgreementStrong agreement
Most discussions reinforce the findings that chloroquine is ineffective against human lung cells with SARS-CoV-2, indicating strong consensus.
InterestHigh interest
Posts demonstrate high engagement with the topic, citing peer-reviewed studies, implications for treatment debates, and scientific explanations.
EngagementModerate engagement
There is active referencing of scientific literature, calls to settle controversies, and discussions about the drug’s pathways, showing thoughtful engagement.
ImpactHigh impact
The collective tone suggests the findings could significantly influence ongoing debates, clinical practices, and future research directions.
Abstract in brief
Chloroquine was initially thought to inhibit SARS-CoV-2 infection based on studies in African green monkey kidney cells, but it does not effectively block infection in human lung cells.
The presence of the cellular protease TMPRSS2 in human lung cells activates the virus in a way that makes chloroquine ineffective, suggesting it targets a pathway not active in lung tissue.
Overall, these findings imply that chloroquine is unlikely to protect against COVID-19 spread in humans, especially in lung tissue where the virus primarily infects.
Furthermore, the presence of the TMPRSS2 protease favors a plasma membrane entry route whereas its absence favors cathepsin-mediated endosomal entry in vitro, as shown by @c_drosten & @snpoehlm
This may also impact apparent neutralization.

Scientist Dr Susan Oliver and Julie discuss science mistakes made by ivermectin supporters, including misinterpretation of data and faulty comparisons to antivirals. The video emphasizes the importance of understanding…
This was the first video I ever made for my channel Unfortunately YouTube removed it after 6 hours After over a year and thanks to the efforts of my supporters they relooked at it and realised they had made a mistake…
Dude. Take a walk before you post. Your initial point was reactionary "slippery slope" nonsense mixed with the emptiest and snarkiest "c'mon bro!" I've seen in a while. This is not worth being that defensive about. Nobody thinks you're "bad" because you speed. They're just fed up with speeding.
That was the argument you were allowed to make BEFORE you lost lmao. After we found out it lost way more votes and that Israel collided with trump while harris sent Ritchie Torres and rapey bill to scold Muslims as their families were killed.

I think it'd result in more deaths than expected.
But i think you have a point, speeding would almost certainly account for more deaths and injuries.
That said, apparently the limiter idea needs work so it doesn't kill people.
Maybe instead of a hard limit, it forces you into lower and lower gears.

we had to pee in a cup for the privilege of working at the company that sent the email marketing campaigns for Bank of America, meanwhile these guys are high as a kite and in charge of the global economy and all our personal information. it’s a cool system, really, no notes.
But have they backfilled the university and research cuts? Are there Canadian researchers who haven been able to access opportunities? What about equity accommodations and services for grad students, currently weak. At the time of the budget announcement I read several comments to that effect.
Researchers found that chloroquine protects NORMAL cells from viruses but ALLOWS viruses to attack CANCER cells.

@SCH451 @pwafork Blocked, but she then tweeted some ad hominems about the VIC CHO and Fauci, and some quotes about HCQ being good for treating SARS-COV.
That was in a *kidney cell line*.

Nature : Chloroquine does not inhibit infection of human lung cells with SARS-CoV-2
Expression of TMPRSS2—a protease that activates SARS-CoV-2 for entry into cells—renders SARS-CoV-2 insensitive to chloroquine.
