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 non-profit organization Border Angels hosted its 32nd-anniversary dinner on Saturday. The dinner raises money to help continue providing the services they offer to immigrants in the community, including water drops for border crossers, legal services, and shelter. The migrant caravan and the upcoming election were hot topics of conversation during the dinner. This year the organization honorees were Margarita Zavala, Kirsten Zittlau and Jacqueline Arellano. Zavala and Zittlau are attorneys. Arellano is the water drop coordinator for Border Angels. Border Angels' founder Enrique Morones tells 10News that he decided to honor women this year. He also encouraged everyone to go out and vote on November 6th saying the president is sending the wrong message about immigrants. Guests at the event also reacted to President Donald Trump deploying the military to the border. At a campaign event, the president was not backing down, saying migrants need to come to the U.S. legally.   1051

SAN DIEGO (KGTV) — The King family, who launched "Chelsea's Light" after the rape and murder of their daughter Chelsea in 2009, has decided to end the popular "Finish Chelsea's Run" event after eight years.In an interview with 10News from the family's home near Chicago, Chelsea's father, Brent, said they are proud of the impact they have been able to have through "Finish Chelsea's Run," but that it was time to move on from the event."Our family wants to thank everybody that has ever come out to run in our race. It's spectacular. It's beautiful. It brings us a lot of joy. But at the same time, it reminds us how we lost our little girl," King said.Chelsea was a 17-year-old student at Poway High in 2010 when she went for a run at Rancho Bernardo Community Park. A registered sex offender, John Gardner, later pleaded guilty to dragging King into a secluded area near Lake Hodges, raping her, and strangling her to death. He buried the body nearby.Shortly after his arrest, Gardner also admitted to the murder of an Escondido teen, Amber DuBois, who had disappeared a year earlier.The King family began the "Chelsea's Light" Foundation, through which it carried out "Finish Chelsea's Run" and a companion baseball tournament. King says "Chelsea's Light" will continue to exist and raise money. However, he has launched a new nationwide organization called "Protect the Joy."King says he will use the experience he gained helping pass "Chelsea's Law" legislation in several states to protect youth from sex offenders to help build a bigger, stronger organization dedicated to issues of defending children."I've built an organization that mirrors the Sierra Club, or the Surfrider Foundation, or Greenpeace. But instead of protecting the trees, or the coastline, or the whales, I'm going to protect our children," King said.For more information on King's new organization, visit the website: ProtecttheJoy.org. 1952

SAN DIEGO (KGTV) - The former Navy sailor accused of killing four people by driving his truck off the Coronado Bridge and onto a crowd attended a motions hearing Friday.Richard Sepolio faces four counts of gross vehicular manslaughter and DUI. His defense team argued to throw out the DUI charge, as well as crucial evidence, including initial conversations between Sepolio and his arresting officers. The judge concluded that both issues would be allowed in the upcoming trial.The nephew of two of the victims wants answers. Jacob Contreras has flown from Chicago to San Diego a dozen times to follow the case in court.RELATED: Parents of driver in Coronado Bridge crash defend son"I'm here a lot. I'm trying to move here,” Contreras said. "My family hasn't celebrated Thanksgiving in two years. Life is just not the same. It's never going to be the same."Contreras is the nephew of Annamarie and Cruz Contreras of Chandler, Arizona, two of four people killed on October 15, 2016. Like the two other victims, Francine Jimenez and Andre Banks of Hacienda Heights, the couple was attending a fundraising event at Chicano Park when Sepolio’s truck suddenly plunged into a crowd, killing them.Sepolio's high-profile attorney Paul Pfingst argued Friday that his client was not read his Miranda rights while being transported to the hospital for his injuries and therefore, the conversations between Sepolio and responding officers should be inadmissible during trial.RELATED: Facebook Live video captures aftermath of bridge crashCHP Officer Juan Carlos Jimenez read from his notes about the initial conversation."I asked if he felt the effects of the alcohol,” Jimenez said. “He said ‘Yep.’”Officer Jimenez also recalled the moments when he gave Sepolio a Breathalyzer test. He believed Sepolio was attempting to fake the test by only pretending to breathe small amounts of air into the device. The test results showed Sepolio's blood alcohol level was 0.08 to 0.09%. RELATED: Social media: Truck flies off Coronado Bridge, lands on crowdThe defense also argued that responding officers never noted Sepolio had “slurred” speech, implying that he may not have been drunk when the accident occurred. Officer Jimenez remembered that Sepolio’s speech was indeed slurred and that he was complaining of back pain. But he admitted that instead of writing he had “slurred” speech, he noted that his speech was “slow.”Jacob Contreras said he was not buying the defense’s argument. "The slurred speech and slow speech, if you're intoxicated, you tend to do both,” Contreras said. “So my point of view is the defendant was intoxicated.”RELATED: Navy man charged with DUI in crash that killed fourNearly two years since the crash, Sepolio has recovered from his injuries. But two families are still left without answers, still seeking justice. 2876
