Scripps Research finds ‘possible Achilles heel’ in the coronavirus
The discovery could help target a weak spot in the virus with strong drugs

Scripps Research in La Jolla reported on Friday that there appears to be a specific area of the coronavirus that could be targeted with drugs and other therapies, a finding that also could help with the development of a vaccine.

Scripps scientists say the spot is crucial to spreading the highly contagious virus, and that its composition suggests that it would be vulnerable to drugs.

The spot “is a possible Achilles heel” in the coronavirus, said biologist Ian Wilson, who led the team that made the finding. The discovery was published Friday in the journal Science.

The advance arose from a huge and growing effort by scientists globally to find human antibodies that can neutralize or destroy the coronavirus.

Wilson examined an antibody that had been taken from a SARS patient years ago and noticed that it latched onto a specific place in that virus.

The team then discovered that the same SARS antibody latched onto virtually the same spot on the coronavirus. The antibody did not grip it quite as hard, but it helped identify the spot as a possible weak point in the makeup of the virus.

“That high degree of similarity implies that the site has an important function that would be lost if it mutated significantly,” Scripps Research said in a statement Friday.

The researchers need to explore the matter further, which won’t be easy.

“We found that this (spot) is usually hidden inside the virus, and only exposed when that part of the virus changes its structure, as it would in natural infection,” Wilson’s colleague, Meng Yuan, said in a statement.

Scripps Research also will search for antibodies that do a better job of latching onto the vulnerable region of the virus.

The institute is seeking the public’s help. Researchers are looking for COVID-19 survivors who would be willing to donate some of their blood, which would then be screened for potentially useful antibodies.

All humans have five basic types on antibodies. But there’s lots of variability among those groups. Scientists are looking for the ones that are best suited to identify and neutralize the virus.

People who wish to participate should contact Scripps Research directly at covid-19survivorstudy@scripps.edu

The institute says that it is particularly interested in talking to people who have been symptom-free for two to three weeks. The antibodies that people produce to fight the virus can become stronger over time, scientists say.

It is thrilling to see scientific research in action.   It certainly brings hope that we can save ourselves from this virus.   Much better to read scientific articles identifying potential weaknesses in the virus and the potential for a combative method rather than articles proclaiming that this virus is a result of human sin.

and yet the 2019-2020 flu season...

So far this season, there have been 45 million flu illnesses, at least 300,000 hospitalizations, and up to 46,000 deaths from flu , of which more than 100 are pediatric--a higher total at this point of the year than any season in the past decade.

New York State is reporting 156,659 positive cases to date, according to the CDC. The latest data (ending March 21) shows a 45% decrease in reported cases from the previous week.

In Monroe County, there have been 17 deaths since October 1 from 5,753 confirmed cases. Of those confirmed cases, 758 were hospitalized.

This novel virus has no vaccine or pills or liquids so far to alleviate or mitigate its symptoms and death factors. It is running 'wild' in and out of the world's people - looking for suitable hosts. Our tools are so far unworthy of the 'Challenger.' So we pull back, use social isolation, and stop the spread of the microbe and its threat. And, pneumonia-related diseases are graded worse and more damaging even before they become highly contagious. My opinion.

Hi SP. My question is this: Did the Swine Flu carry a general 'signature' of severe pneumonia or fatal breathing problems? Or was the Swine Flu more of a flu-sickness? Curious.

7.1.3  seeder  Split Personality  replied to  CB @7.1.2    4 years ago

Tough answer, it more closely resembles influenza with the usual symptoms that for many developed into pneumonia and or respiratory failure.

Like COVID19, H1N1 did not respond to previous medicines or vaccines.

We went through the same thing with swine flu without shutting down the country.

The BIG difference is that there was extensive testing and surveillance for H1N1 so we knew who was infected even if they were asymptomatic and they were quarantined, while those who tested negative but had 'flu like' symptoms were not.

7.1.5  CB  replied to  Dulay @7.1.4    4 years ago

Another matter which makes this highly contagious virus able to shut down the country is the speed of its transmission and progression to respiratory failure. It's speed of progression, our lack of immunity or a vaccine, its high contagion factor, and its capacity to overwhelm doctors and nurses and facilities all add up to shutting down the country.

I saw that Ford will deliver 50,000 ventilators at approximately $16,750 a piece  starting with 6,000 in June.

GM was "forced " to sign a contract for 30,000 at the same price with initial deliveries estimated for mid June.

Wanna start a pool on how many ventilators are in the national stockpile by September?

Under 100K or over?

I am old enough to remember the Rambler's original public relations failure when a very large batch of steering knuckles failed regularly enough, causing partial disconnect of one of the cars front wheels.

Later when there the cars were more reliable with Ford or GM engines paired to Chrysler tranmissions, it was the bizarre things that haunted AMC reliability were generally tied to AMC's shaky financial status.

Used car lots everywhere had Pacers with the front door handle broken off and the part supplier refused to sell them to AMC on credit.  What good is a car you can't get into.

Ahhhh memories.

Erica Ollmann Saphire will direct the team from her lab at the La Jolla Institute

March 30, 2020
11:52 AM
A San Diego biologist who earned high acclaim for fighting the Ebola virus will lead an international team of scientists in the search for antibodies that can treat COVID-19, a strategy that public health officials say could end up saving countless lives as the pandemic unfolds.

Erica Ollmann Saphire will direct the team from her lab at the La Jolla Institute (LJI), which received $1.73 million Monday from the Bill and Melinda Gates Foundation to create a coalition that will initially have contributors from about a dozen institutions. The figure could quadruple.

“There are universities, companies and laboratories that are discovering therapeutic candidates that might work against the coronavirus,” said Saphire, who helped run a similar team to battle Ebola.

“The Gates Foundation is asking us to take everyone’s molecules, compare them side by side, and figure out which ones would be right for human treatment.”

The team is focusing on antibodies because they represent the first line of defense for humans. Antibodies identify bacteria and viruses, some which can be harmful or deadly. The antibodies latch on to the bad ones and remove them from the body, much as a bouncer would remove an unruly customer from a night club

Erica and Co. you are 'greenlighted' to come along! Welcome aboard!

Also attending the press conference were Director Mark Ghilarducci, Cal OES, left, Los Angeles Mayor Eric Garcetti, second from right, and Dr. Mark Ghaly, Secretary of Health and Human Services, far right, along with others not shown.

“We decided enough’s enough. Let’s use the power, the purchasing power of the state of California, as a nation-state,” Newsom told MSNBC host Rachel Maddow. “We did just that. And in the next few weeks, we’re going to see supplies, at that level, into the state of California and potentially the opportunity to export some of those supplies to states in need.”

Your computer can help scientists seek potential COVID-19 treatments

IBM's World Community Grid hosts Scripps Research project to virtually screen chemical compounds that might help fight COVID-19.

April 01, 2020


LA JOLLA, CA — Under a collaboration between IBM and Scripps Research, anyone in the world with a PC, laptop or Mac and an internet connection will be able to help scientists seek chemical compounds that might be effective against COVID-19.

To do so, volunteers' devices will perform small, virtual experiments to identify chemical compounds, including those in existing medicines, that might be used as treatments candidates for COVID-19. Compounds that show promise for treating COVID-19 will undergo further testing and analysis. 

The project, designed and led by Scripps Research, will be hosted on IBM's  World Community Grid , a trusted, crowdsourced computing resource provided at no charge for scientists.

Volunteers download a small, safe app that works when their devices are otherwise idle or in light use. Operating unobtrusively in the background without slowing users' systems, the app distributes computational assignments and returns completed calculations to researchers, all via the IBM cloud. Volunteers need not have any special technical expertise to participate; the process is automatic and secure. Personal information is never shared, and the software cannot access personal or business files. (You can sign up to participate  at www.ibm.org/OpenPandemics .) 

By crowdsourcing power from thousands of computing devices, the project, called "OpenPandemics - COVID-19," will easily be able perform hundreds of millions of calculations needed for simulations. This can potentially accelerate the drug discovery or drug re-purposing process, traditionally performed more slowly in a traditional laboratory. As with all of IBM’s World Community Grid projects, all data generated by this effort will be made publicly available.
