SAN DIEGO (KGTV) — The National Institutes of Health highlighted research Tuesday out of UC San Diego that could unlock a new way to treat COVID-19.The research reveals new insight into how the coronavirus hijacks cells, and how doctors might be able to set traps or decoys to combat the virus. The findings were published in the journal Cell last month.“It does open up another avenue for a potential treatment,” said UC San Diego distinguished professor Dr. Jeffrey Esko. “It’s not a cure. It would be something that would tamp down infection potentially.”Since January, scientists around the world have understood that SARS-Co-V2, the official name of the new coronavirus, enters cells by latching onto a specific receptor on the cell’s surface, called ACE2.The UCSD team, led by Dr. Esko and visiting scholar Dr. Thomas Clausen, discovered that this entry mechanism is actually a two-step process, and the virus must also attach to a long chain of sugars called heparan sulfate.“We’ve shown this is fundamental to the infectious mechanism, so it needs to be part of every study from now on,” said Clausen.All cells are coated with a complex layer of sugars, or carbohydrates, called glycans. Heparan sulfate is one type of glycan that is known to play a key role in the infection process in several viruses, including herpes and other coronaviruses.It’s a complicated process to picture so the researchers offer an analogy: imagine a bird, soaring over trees, hunting a worm on the forest floor. The bird is the coronavirus and the trees are the thick layer of glycans that coat the surface of the cell.To reach the worm, which in this case is the receptor ACE2, the bird must navigate its way through the trees, specifically through heparan sulfate.The UCSD found that by removing the heparan sulfate trees with an enzyme, they were able to prevent the virus from infecting cells. In laboratory testing, they also found a second technique worked to foil the virus: introducing more trees as bait.The team found that heparin, an FDA-approved drug that is similar in structure to heparan sulfate, successfully acted as decoy. Heparin is a widely used drug designed to treat blood clots. Since blood clots and strokes are common complications with COVID-19, many doctors already administer heparin to patients.The UCSD team demonstrated that the two approaches can block infection in lab-grown cells about 80 to 90 percent of the time.“Certainly in the laboratory you can demonstrate that it works, but to deploy it and use it as a therapeutic has not been demonstrated,” Esko said.The NIH noted that more studies are planned to explore whether heparin, heparan sulfate, or drugs that target heparan sulfate might yield a viable COVID-19 treatment.Dr. Esko said he’s already been in talks with companies that plan to use their study as a rationale for a clinical trial.“It is very humbling when you realize we’re working on a pandemic right now, and maybe what we’ve done can contribute to a treatment for the disease,” he said. 3038

SAN DIEGO (KGTV) - The eight-legged population is overrunning parts of Balboa Park a bit earlier than usual this year.Spider season is in full bloom in San Diego. From Rancho Penasquitos to downtown, people say they are finding webs just about everywhere including hiking trailsOne person wrote on a local Reddit thread they stopped hiking because there were so many webs.Chris Conlan works with San Diego County Vector Control and says there's nothing on usual with what folks are seeing.“They hatch out in the spring and they’re small and make very small webs,” said Conlan. "But as they begin to grow over the course of the summer and beginning of fall where we are right now, they’re much larger they tend to spin bigger webs and those are they kind of webs people walk into freak out and do the spider dance."Conlan says the webs people are bumping into on trails are likely orb weavers’. They are poisonous, but their venom is not toxic to humans like other spiders.“It’s really just the black and the brown widow that people need to worry about and they tend to spin more out of the way webs in corners and dark places," said Conlan. "They’re not the type of web you’re just going to go walking through."Conlan’s advice for folks’ encountering spider’s homes is as good anyone’s.“Carry a stick in front of you,” said Conlan with a laugh. "And be prepared to wipe web off your face from time to time.” 1420

SAN DIEGO (KGTV) -- The man accused of killing his stepmother and burying her body in the backyard of a Tijuana home pleaded guilty to unrelated drug charges Tuesday. Aaron Seth Juarez, 20, pleaded guilty to possession of heroin for sale and agreed to a two-year state prison sentence. Juarez was taken into custody in San Diego earlier this month for probation violations. He’s also wanted by the Deputy Attorney General of Justice in Tijuana on suspicion of killing Fernanda González Serrano in February.RELATED: Man suspected of killing stepmother found in Tijuana backyard arrestedGonzález was last heard from on Feb. 2. Shortly after her disappearance, her husband was treated for a gunshot wound in San Diego, but was reportedly unable to answer any questions.After posting on social media in search of González, her sister, Erika, received a call not to keep searching, and that González, "was already dead and in the back of her yard."Erika and her father went to González’ Tijuana home and started digging in the backyard, where they discovered González’ body.RELATED: Man accused of killing, burying stepmom in Tijuana appears in courtMexican police believed Juarez may have returned to the U.S. on Feb. 23. 1225

SAN DIEGO (KGTV) - The largest employer in the country is waving away a long standing tradition. Walmart is planning to phase out its greeters at more than 1,000 stores across the country. The retail giant says it is moving forward with a new role called “customer host” that is more physically demanding. The hosts will still greet people but must also be able to pass physical exams including lifting a 25-pound box and climbing ladders. Critics say the move targets their elderly and disabled employees, which make up a significant portion of the company’s greeters. “I can’t do that,” said Adam Catlin, who has cerebral palsy and has worked as a Walmart greeter for a decade. Walmart says it is striving to place greeters in other jobs at the company and the title of greeter will be officially eliminated April 26. “I want to keep my job past April 26 because I have made a lot of good friends and a lot of good memories over the years,” added Catlin. Walmart has not said how many greeters will lose their jobs but adds it is, “extending the current 60-day greeter transition period for associates with disabilities while we explore the circumstances and potential accommodations, for each individual, that can be made within each store.” 1252

SAN DIEGO (KGTV) - The manager of a Cricket Wireless store in Pacific Beach is hoping the public can help identify two men involved in tagging the back of the store. Blake Beadle, the store manager, said newly installed cameras captured two men approach the store on Garnett Avenue on Monday night at around 9:30 p.m.One of the men approached the back of the store and appeared to spray paint something on the back wall. Meanwhile, the other man stood watch.Beadle said he had just painted over the spot a week and a half ago, when vandals had hit the same spot. “It seems like as soon as we paint over it, within a few weeks it gets tagged again in a similar fashion,” said Beadle. He reported the latest incident to police. He said he hopes the video can help identify the suspects. 792
