Researchers across the country are focusing on all things COVID-19 — from biotherapies and treatment to vaccines and prevention. A handful of researchers based out of the University of Houston are doing their best to move the needle on a cure or reliable vaccine.

Here are three research projects currently ongoing at UH.

UH pharmacy professors take it back to basics

When thinking about how to prevent the spread of COVID-19, two UH pharmacy professors are looking at how the virus enters the body. Then, this information can help develop protection of that entry point.

"The human entry of coronaviruses depends on first binding of the viral spike proteins to human cellular receptors that basically offer a cellular doorknob," says Gomika Udugamasooriya, associate professor of pharmacological and pharmaceutical sciences, in a press release. "The virus latches onto the specific human cellular receptor, ACE2, and sneaks inside to replicate itself within the cell to spread throughout the body."

Now, the goal of new drugs and vaccines is to protect that ACE2. Udugamasooriya is working with Bin Guo, associate professor of pharmaceutics, on this research, which is in the initial screening levels and identified drug-lead validations. They are working to apply their unique cell-screening technology to identify specific synthetic chemical drug leads called peptoids that can bind to ACE2 receptor, according to the release.

"Peptoids are easier to make, compatible with biological systems and economical to produce," says Udugamasooriya.

Duo aims to create inhalation vaccine for COVID-19

If the disease itself is airborne, can't the vaccine be too? That's what M.D. Anderson Associate Professor of Chemical and Biomolecular Engineering Navin Varadarajan looking into.

"For airborne pathogens, the nasal mucosa is the first point of defense that needs to be breached," says Varadarajan in a news release. "Mucosal immunity and vaccines are fundamentally important for a wide range of pathogens including influenza, severe acute respiratory syndrome coronavirus (SARS-CoV) and the current SARS-CoV-2."

Varadarajan is focusing on the spike protein to protect at virus entry. These proteins are known for building strong immune responses, flexibility and scalability, and absence of infectious particles. He is working with Xinli Liu, associate professor of pharmaceutics.

"As with any vaccine, a variety of factors determine their efficacy including the antigen used for electing a response, the adjuvants and immunomodulators, the efficient delivery of the antigen to appropriate target cells, and the route of vaccination," Varadarajan says.

The man with three different vaccine options

Shaun Zhang, director for the Center for Nuclear Receptors and Cell Signaling, usually works on developing treatment or vaccines for cancer and viral infection. Now, he's switched gears to work on three different vaccine candidates for COVID-19.

"The data collected from our studies show that our vaccine candidates can generate neutralizing antibodies, which can protect cells from infection by SARS-CoV-2 when tested in vitro," says Zhang in a press release. "We are now working on further improvement for the vaccine design."

Zhang's approach is neutralizing antibody production, and he's tapped into using "subunit vaccine containing either the entire spike protein or the receptor binding portion, which helps the virus enter the target cell, and delivered either by DNA formulation or by a herpes simplex virus-based vector," according to the release. Low cost and simplicity are two priorities for Zhang's work.

Rice scientist tapped by NASA for Mars mission

robo-naut

A Rice University Martian geologist has been chosen by NASA as one of the 13 scientists who will be working on a new Mars rover.

Perseverance, the rover that launched in July and is expected to land on Mars in February. It will be scouting for samples to bring back to study for ancient microbial life, and Kirsten Siebach — an assistant professor of Earth, Environmental and Planetary Sciences — will be among the researchers to work on the project. Her proposal was one of 119 submitted to NASA for funding, according to a Rice press release.

"Everybody selected to be on the team is expected to put some time into general operations as well as accomplishing their own research," she says in the release. "My co-investigators here at Rice and I will do research to understand the origin of the rocks Perseverance observes, and I will also participate in operating the rover."

Perseverance is headed for Jezero Crater, a 28-mile-wide area that once hosted a lake and river delta where, according to scientists, microbial life may have existed over 3 billion years ago. Siebach is particularly excited hopefully find fossils existing in atmospheric carbon dioxide dissolved in water — which usually exists as limestone on Earth.

"There are huge packages of limestone all over Earth, but for some reason it's extremely rare on Mars," she says. "This particular landing site includes one of the few orbital detections of carbonate and it appears to have a couple of different units including carbonates within this lake deposit. The carbonates will be a highlight of we're looking for, but we're interested in basically all types of minerals."

Siebach is familiar with rovers — she was a member of the team for NASA's Curiosity rover, which has been exploring Mars since 2012. For this new rover, Siebach knows what to expect.

"Because there is only one rover, the whole team at NASA has to agree about what to look at, or analyze, or where to drive on any given day," Siebach says in the release. "None of the rovers' actions are unilateral decisions. But it is a privilege to be part of the discussion and to get to argue for observations of rocks that will be important to our understanding of Mars for decades."

Siebach and her team — which includes Rice data scientist Yueyang Jiang and mineralogist Gelu Costin — are planning to tap into computational and machine-learning methods to map out minerals and discover evidence for former life on Mars. They will also be using a Planetary Instrument for X-ray Lithochemistry, or PIXL, to analyze the materials.

The return mission isn't expected to return until the early 2030s, so it's a long game for the scientists. However, the samples have the potential to revolutionize what we know about life on Mars with more context than before.

"Occasionally, something hits Mars hard enough to knock a meteorite out, and it lands on Earth," she says in the release. "We have a few of those. But we've never been able to select where a sample came from and to understand its geologic context. So these samples will be revolutionary."

Tech giant Hewlett Packard Enterprise taps Houston area for global headquarters relocation

here comes HPE

Thousands of potential jobs are coming to the Bayou City region with a major move by a Fortune 500 company. Hewlett Packard Enterprise (HPE) and Texas Gov. Greg Abbott have announced that HPE will relocate its global headquarters to Spring, Texas from San Jose, California.

The headquarters will be located in a new state-of-the-art campus that will open in early 2022, and will build on the company's established presence in the state of Texas, according to a press release. The new campus, being built in the 60-acre Springwoods Village development, will consist of two five-story buildings with some 440,000 square feet of combined space. HPE already boasts a significant footprint in the Houston region, with more than 2,600 area employees, the Greater Houston Partnership notes.

HPE cited Houston's diverse talent base and low cost of doing business as key factors driving the move to the digital tech hub and global headquarters city.

A global enterprise information technology company that helps customers drive digital transformation by "unlocking value from all of their data," HPE delivers unique, open, and intelligent technology solutions, per the GHP. It works to create a consistent experience across all clouds and edges, to help customers develop new business models, engage in new ways, and increase operational performance. HPE has a long Houston pedigree, as Hewlett Packard merged with Compaq Computers in 2002. The company was founded in 2015 following the separation from HP, Inc., and is currently ranked 109 on the list of Fortune 500 companies.

Texas is already the site of HPE locations in Austin, Plano, and Houston. It currently operates major product development, services, manufacturing, and lab facilities in Houston and Austin.

The Houston move would no doubt be a boon to the local economy and create myriad jobs in the sector.

"As we look to the future, our business needs, opportunities for cost savings, and team members' preferences about the future of work, we are excited to relocate HPE's headquarters to the Houston region," said Antonio Neri, CEO of HPE, in a release. "Houston is an attractive market to recruit and retain future diverse talent and where we are currently constructing a state-of-the-art new campus. We look forward to continuing to expand our strong presence in the market."

Abbott applauded the move in a statement, noting, "We are excited that Hewlett Packard Enterprise has chosen to call Texas home, and I thank them for expanding their investment in the Lone Star State by relocating their headquarters to the Houston region. Hewlett Packard Enterprise joins more than 50 Fortune 500 companies headquartered in the Lone Star State, including 22 in the Houston area alone. That is because Texas offers the best business climate in the nation. Our low taxes, high quality of life, top-notch workforce, and tier one universities create an environment where innovative companies like HPE can flourish. We look forward to a successful partnership with HPE, as together we build a more prosperous future for Texas."

With fresh funds, Houston startup plans to represent the future of fireproofing

HOUSTON INNOVATORS PODCAST EPISODE 60

A few years ago, Mike Francis caught a video of a man's hand coated in some sort of material and placed over a fire. Nothing was happening to the man's hand — the coating completely protected it — but something was happening in Francis's brain, and a year ago he founded Nanotech Inc.

Based in Houston, NanoTech' is focused on reducing energy waste by proper insulation within the construction industry — a half inch of NanoTech's material is the equivalent of 30 inches of fiberglass. However, perhaps more important to Francis is the life-saving capability the product provides in terms of fireproofing.

"We're working with all of the major players in the state of California to not only fireproof the utility infrastructure, but eventually homes and businesses," Francis says on this week's episode of the Houston Innovators Podcast. "Our goal, if we're looking into the future, is to fireproof that state — and we're working with the right people and companies to make it happen."

To the best of his knowledge, Francis says NanoTech is the only company this far along working on this goal. Millions of utility poles go up in flames as the forest fires sweep through the state, and coating them with NanoTech could help prevent this damage.

Of course, as the company grows, Francis is lucky to have the support and the funds behind him and his team. Earlier this year, Halliburton selected NanoTech as the inaugural member of Halliburton Labs. For the past few months, NanoTech has been based in the labs, receiving hands-on support, and NanoTech will join the year-long inaugural cohort of 15 or so companies in 2021.

NanoTech also has a new member to its support system — and $5 million — following the close of its seed round led by Austin-based Ecliptic Capital. Francis says he was looking for an investor to bring new expertise the company doesn't have yet, and Ecliptic will be crucial to growing globally.

"Those first investors, especially in your seed round, are critical to your growth," says Francis. "We're so excited to be partnering with Ecliptic — we just trusted them."

Francis shares more about fundraising during a pandemic and what being based at Halliburton has meant for his company's growth. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.
