A COVID-19 research breakthrough out of a Texas university comes from unlikely source

In the race to find a treatment for the novel coronavirus, researchers at the University of Texas at Austin have announced a potential breakthrough — thanks to a llama.

Scientists from Texas' flagship university who have been collaborating with the National Institutes of Health and Ghent University in Belgium identified an antibody treatment that could potentially neutralize the virus that causes COVID-19.

The researchers detail their work in the May 5 edition of Cell, a scientific journal.

"This is one of the first antibodies known to neutralize SARS-CoV-2," said Jason McLellan, associate professor of molecular biosciences at UT Austin and co-senior author of the paper, in a release. (FYI, SARS-CoV-2 is referring to the virus that causes COVID-19.)

Using a Belgian llama named Winter, scientists were able to identify two antibodies the animal produces when it comes into contact with a foreign body (such as the coronavirus). The first is similar to a human antibody and the second is much smaller, about one-quarter of the size of the other.

Researchers were able to link two copies of this special llama antibody to create a new antibody. This new antibody binds tightly to a key protein on the coronavirus germ that causes COVID-19 and could possible be nebulized and put into an inhaler.

"That makes them potentially really interesting as a drug for a respiratory pathogen because you're delivering it right to the site of infection," said Daniel Wrapp, a UT graduate student in McLellan's lab and co-first author of the paper.

Unlike vaccines, which can take up to two months to take effect, antibody treatment can be used in more vulnerable populations as a way to fight off the virus.

"Vaccines have to be given a month or two before infection to provide protection," McLellan said. "With antibody therapies, you're directly giving somebody the protective antibodies and so, immediately after treatment, they should be protected. The antibodies could also be used to treat somebody who is already sick to lessen the severity of the disease."

From here, research turns to preclinical studies, using hamsters and primates for testing. If successful, they will move onto humans.

If you're wondering just how a group of researchers living in different parts of the globe were able to make this discovery seemingly overnight, that's because they've actually been working on it since 2016, when Winter was just 9 months old.

The experiment began as a way to develop vaccinations for two earlier versions of the coronavirus: SARS-CoV-1 and MERS-CoV. Their years of research allowed the scientists to pivot in recent months to isolating the protein in COVID-19.

As for Winter, she's now 4 years old and still lives with about 130 llamas on a farm in Belgium, likely unaware of her contribution to potentially altering the course of COVID-19 forever.

Originally expected to raise $150 million, Mercury's latest fund is the largest raised to date. Photo via mercuryfund.com

A Houston venture capital firm has announce big news of its latest fund.

Mercury, founded in 2005 to invest in startups not based in major tech hubs on either coast, closed its latest fund, Mercury Fund V, at an oversubscribed amount of $160 million. Originally expected to raise $150 million, Fund V is the largest fund Mercury has raised to date.

“We are pleased by the substantial support we received for Fund V from both new and existing investors and thank them for placing their confidence in Mercury,” Blair Garrou, co-founder and managing director of Mercury Fund, says in a news release. “Their support is testament to the strength of our team, proven investment strategy, and the compelling opportunities for innovation that exist in cities across America.”

The fund's limited partners include new and existing investors, including endowments at universities, foundations, and family offices. Mercury reports that several of these LPs are based in the central region of the United States where Mercury invests. California law firm Gunderson Dettmer was the fund formation counsel for Mercury.

Fresh closed, Fund V has already made investments in several companies, including:

  • Houston-based RepeatMD, a patient engagement and fintech platform for medical professionals with non-insurance reimbursed services and products
  • Houston and Cheyenne Wyoming-based financial infrastructure tech platform Brassica, which raised its $8 million seed round in April
  • Polco, a Madison, Wisconsin-based polling platform for local governments, school districts, law enforcement, and state agencies
  • Chicago-based MSPbots, a AI-powered process automation platform for small and mid-sized managed service providers

Mercury's investment model is described as "operationally-focused," and the firm works to provide its portfolio companies with the resources needed to grow rapidly and sustainably. Since 2013, the fund has contributed to creating more than $9 billion of enterprise value across its portfolio of over 50 companies.

“Over the past few years there has been a tremendous migration of talent, wealth and know-how to non-coastal venture markets and this surge of economic activity has further accelerated the creation of extraordinary new companies and technology," says Garrou. "As the first venture capital firm to have recognized the attractiveness of these incredible regions a dozen years ago, we are excited to continue sourcing new opportunities to back founders and help these cities continue to grow and thrive.”
