SAN DIEGO (KGTV) — Researchers at the University of California, San Francisco are working on a spray designed to block the novel coronavirus from hijacking cells in the body, like a biological mask or internal personal protective equipment.They’re doing it by borrowing a defense mechanism from an unlikely source: llamas.The team, led by UCSF graduate student Michael Schoof, engineered a synthetic molecule based on one found in a llama’s immune system that acts like an antibody but is one-tenth the size.Human antibody treatments, known as convalescent plasma, require a transfusion in a hospital setting. But this smaller molecule, called a nanobody, can be easily self-administered via an inhaler or nasal spray and rapidly manufactured using yeast, Schoof said.The scientists named their product AeroNabs. They say it could be an inexpensive intervention for treating and preventing COVID-19 while the world waits for a vaccine.“We don't know how effective vaccines will be. We don't know how long it will take to rapidly deploy them, so we envision this product as hopefully a bridge until there is widespread, effective vaccination,” Schoof said.Once a vaccine is available, AeroNabs could offer protection for individuals who are unable to be inoculated for health reasons, he said, or an early treatment option.The team is in talks with commercial partners and hopes to begin clinical trials soon.In the 1980s, Belgian scientists discovered that about half of the antibodies in camels, llamas and alpacas are shaped differently than the antibodies found in other mammals, including humans. Researchers later learned they could use a fragment of these oddly shaped camelid antibodies to bind to antigens.Those fragments are called nanobodies.Currently, there is only one FDA-approved drug that uses nanobodies. Caplacizumab was approved last year to treat a rare blood disorder.The team at UCSF sifted through billions of nanobodies to find one that binded best to the spike proteins on the coronavirus, then engineered it to stick even better.The coronavirus uses its spikes to enter cells and replicate; the spikes are essentially the pathogen’s key into the body. By coating the spikes with nanobodies or antibodies, the viral key no longer fits into the body’s receptors and the virus can’t get in.“This works in the lab. It needs to be translated into the clinic,” said Schoof.The team at UCSF still needs to figure out the best delivery method, whether it is a nebulizer, an inhaler or a nasal spray. 2524

SAN DIEGO (KGTV) — San Diego Lifeguards and firefighters responded to Blacks Beach on Sunday to rescue an injured paraglider from a ravine.The 27-year-old woman, who is a pilot, was teaching an advanced training course for paragliding when she lost lift and her parachute collapse, according to lifeguards.Witnesses told lifeguards that the woman tried to brace her impact with her legs as she landed into a ravine next to a popular trail called "Citizens Trail."Lifeguards say the woman was far from the trail when she landed and San Diego Fire-Rescue was called to perform a technical rescue to lift her up the trail.The pilot was taken to a nearby hospital, though the extent of her injuries was not clear, lifeguards said. 734

SAN DIEGO (KGTV) - San Diego Police are opening new locations for San Diegans to conduct business safely. Each San Diego Police division will have a Designated Online Transaction Space (D.O.T.S.) where carrying out online or private sales and exchanges of goods. The space will be in view of the station’s front door and in a well-lit area. “Online platforms have become an epicenter for scam artists and predators looking to take advantage of innocent people. In a world filled with online transaction uncertainty, D.O.T.S. offers certainty. I am pleased to see my pilot program expand citywide. You truly cannot put a price tag on peace of mind,” stated Councilmember Chris Cate. The first D.O.T.S. was created more than two years ago at SDPD Northeastern Division in Rancho Pe?asquitos.Find locations here. 817

SAN DIEGO (KGTV) -- San Diego is expecting cooler temperatures this week, but another heatwave isn't far behind. Local air conditioning companies have been swamped with service calls. Philo Mitman is a service technician with ASI The White Glove Guys."When this heat does come, our call volume is tripled, quadrupled cause everyone needs it now," said Mitman. Mitman said it's important to replace filters, possibly every month, depending on use. "A dirty filter is the biggest thing as a homeowner that can cause bigger issues because if that is neglected the big motors can get seized up, they can overheat , you can block coils off which causes big, big problems," said Mitman.Another common mistake, according to Mitman, is closing vents. "Common misconception is that people close vents off to save money, when in fact, it actually costs you more money when you do that because your system is designed for a certain amount of air flow to be delivered to the home and if you start cutting that off , the system tries to make up for that so it works extra harder," said Mitman. Mitman also suggests testing the system before it's needed."Run some stuff, it's like an old car, you can't just let it sit forever you gotta test it out." 1244

SAN DIEGO (KGTV) - San Diego Police are investigating what led to the death of a man while in police custody last week in Paradise Hills.Police said 39-year-old Guillermo Corrales was arrested on April 16 in the 6300 block of Clyde Ave. after reports of a relative becoming violent.
