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) -- Rep. Susan Davis of the 53rd Congressional District won’t seek re-election in 2020, the Congresswoman announced Wednesday. Davis was first elected to Congress in 2000. “I have struggled to make this very difficult decision. I will not seek another term in Congress. My decision today represents a desire to live and work ‘at home’ in San Diego,” she said. Davis is currently the second highest-ranking Democrat on both the House Education and Labor Committee and the House Armed Service Committee. Among measures recently supported by Davis is the Green New Deal, introduced by Rep. Alexandria Ocasio-Cortez. She also helped spearhead the repeal of the “don’t ask, don’t tell,” a Clinton-era policy which allowed LGTBQ people to serve in the military only if they remained in the closet.“It makes us a better military, a better country, and I was very happy to be a part of that,” said Davis.So far, only two other candidates have officially entered the race. Jose Caballero, a Navy veteran, filed earlier this year and has raised ,900 as of June.Joaquín Vázquez, the son of undocumented immigrants, has also filed to run, but has not submitted any fundraising documents yet to the FEC.Both are Democrats with no previous experience as elected officials.In 2018, Davis faced off against Republican challenger, Morgan Murtaugh, beating her by a nearly 40% margin. Murtaugh has not announced whether or not she plans to run again.Rep. Scott Peters of the 52nd Congressional District released the following statement after the announcement: 1568

SAN DIEGO (KGTV) - San Diego County health officials are focusing their efforts to reduce COVID-19 cases in hard-hit disadvantaged communities.Since the state released its tiered reopening system, County officials have closely monitored case rates and positivity rates, the two metrics that move counties between restrictive and less restrictive tiers.Now, the state has added a new metric relating to equity. It focuses on disadvantaged communities. The state looked at several factors that influence health in communities, including economics, education, transportation, social, neighborhood/environment, and housing conditions. The metric is meant to focus on those communities and their risk to COVID-19.At a news conference Wednesday, County officials say they are working to create a plan to address equity and submit to the state next Thursday. They also say the state will release additional guidelines on Monday.The county's health equity rate is at 6.2, which falls under the red tier. That number needs to drop below 5.2 to meet the orange tier criteria.San Diego County is currently already operating in the red tier based on the other two metrics. The county's positivity rate is at 3.5, Which meets the criteria for the orange tier. But the county's state calculated adjusted case rate is 6.5 new daily infections per 100-thousand people, which falls in the red tier. The red tier allows many businesses to reopen their indoor operations, though at a limited capacity.County officials said the new health equity metric does not play a factor in moving San Diego back into a restrictive tier. But it does play a role in moving to a less restrictive tier.County health officials have been working to reduce COVID-19 cases in disadvantaged communities through outreach and education, testing, and contact tracing, but feel more could be done."Undoubtedly, there's more we can do," Supervisor Nathan Fletcher said. "So even though we've done all of those things and continue to do those things, we will continue to search out more opportunities to address the inequity issues in trying to help those communities who are most impacted." 2153
