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

us save money so we can actually purchase stuff that we do need," Castelo says. "It allows me to focus more on my school and be able to go to work without having to worry that my brother doesn't have something to eat."Free healthcare services were also provided at the marketplace by Kaiser Permanente. 1095

SAN DIEGO (KGTV) - San Diego Congresswoman Susan Davis wants the Navy to analyze whether there is a national security threat related to sewage spills along the US-Mexico border.The military is set to build a billion Navy SEAL training facility near Imperial Beach. The area has experienced 160 days of sewage spill closures to parts of its shoreline over the past three years, Davis reports.Davis wants a Navy assessment of how construction and future training at the site could be affected by the spills. “We need a whole of government solution to the sewage spills,” said Davis. “We know the environmental and economic impact these spills have. What we don’t know, with the Navy planning to stage training operations in potentially contaminated waters, are the national security concerns. The Navy should take a look at this and coordinate with relevant agencies to assess what can be done to prevent future spills.”Davis, a senior member of the House Armed Services Committee, wants to include language in this year’s defense bill to get a report from the Navy on the matter.“The Navy’s coastal campus will be vital for national security,” Davis said. “The last thing we want is our elite Navy SEALs training in water contaminated with sewage. Nor do we want training operations delayed.”Davis is requesting the Navy work with the Department of State, the EPA, the Department of Homeland Security, the International Boundary Water Commission, and the Department of the Interior to assess how national security will be affected by future spills and how they can be prevented. 1598

SAN DIEGO (KGTV) - San Diego Mayor Kevin Faulconer met with leaders from the Marine Corps on Thursday to officially strengthen their partnership. They signed a Memorandum of Understanding between their organizations to work together on "Smart City" technologies such as unmanned aircraft systems (UAS), smart streetlights, renewable energy, and the City's "Get it Done" app. Last year the City of San Diego was selected for a pilot program by the U.S. Department of Transportation to advance the testing of UAS, more commonly referred to as drones. They're already being used by police and fire in Chula Vista. "We will share our experiences, we'll share as we discover uses for data together, and share how advanced technology can benefit the people that we both serve," said Mayor Faulconer. Military leaders say the want to embrace new technologies while also balancing the need for security and safety on bases. 924
