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.

Innovative Houston nonprofit partners with county organization to provide maternal health services

TEAM WORK

PUSH Birth Partners, a Houston-based maternal health nonprofit, is teaming up with the Harris County Public Health Department to provide doula services for over 200 pregnant people free of cost.

Jacqueline McLeeland, CEO and founder of PUSH, says the program will begin in August and aims to improve maternal health and birth outcomes for vulnerable populations. McLeeland says the organization has built up a strong doula training program through their collective in partnership with March of Dimes and several local doula organizations.

McLeeland says PUSH aims to address poor maternal health outcomes for women of color in part by training more doulas of color who can help reduce racial disparities in care. A 2021 study by Harris County Public Health found Precinct 1, which is predominantly composed of people of color, had the highest maternal mortality rate of the county.

Through their collective, PUSH has trained two cohorts of doulas through an integrated care model, focused on providing collaborative care with medical providers in the healthcare system.

“Our programs are designed to advance health equity, we see the numbers, we see that women of color, specifically Black women in that group are disproportionately impacted,” McLeeland tells InnovationMap.

After receiving a $100,000 grant from the Episcopal Health Foundation in 2023, PUSH began their doula expansion program in Houston and they have since received an additional grant from EHF for the next fiscal year. McLeeland shares PUSH has also launched a pilot program called Blossoming Beyond Birth, sponsored by the Rockwell Fund, targeted towards improving maternal mental health through weekly support groups in Houston.

“It’s very exciting to know that we have come this far from where we started and to see how everything is coming together,” McLeeland shares.

For McLeeland, improving maternal health outcomes and providing support to people experiencing high-risk pregnancies are deeply personal goals. McLeeland has sickle cell anemia, a condition that can cause serious complications during pregnancy. During her first pregnancy in 2015, McLeeland was placed on bed rest two months before her due date at which point she had been working in clinical research within the pharmaceutical industry for over 12 years.

“People don’t realize the magnitude of what women go through, during pregnancy and after,” McLeeland says. “There’s a lot of emotional, psychological, and physical tolls depending on how the pregnancy and delivery went.”

After giving birth to her first child, McLeeland took maternity leave, during which she began to research maternal morbidity and mortality trends, information which she says was not widely discussed at the time.

McLeeland says entering the maternal healthcare field felt like a necessity following her second pregnancy. Several months after giving birth to her second child, McLeeland says she received a bill for a surgical procedure that was performed during her cesarean section without her or her husband’s consent. McLeeland says that was the first time she was made aware of the surgery.

“The procedure that was claimed to have been performed could have put my life in jeopardy by hemorrhaging based off of additional research I did once, I came across that information,” McLeeland explains. “These are some of the things that happen in the healthcare system that make people skeptical of trusting in the healthcare system, trusting in doctors.”

McLeeland says the key to improving maternal and birth outcomes for vulnerable populations is to encourage the partnership between doulas, community healthcare workers, and physicians and hopes to further this collaboration through future programming.

Houston-based clean energy site developer raises $300M to decarbonize big tech projects

fresh funding

Houston energy executives have started a new company dedicated to developing clean-powered infrastructure for the large electric loads.

Cloverleaf Infrastructure, dually headquartered in Houston and Seattle, Washington, announced its launch and $300 million raised from NGP and Sandbrook Capital, two private equity firms. The company's management team also invested in the company.

As emerging technology continues to grow electricity load demand, Cloverleaf has identified an opportunity to develop large-scale digital infrastructure sites powered by low-carbon electricity.

"The rapid growth in demand for electricity to power cloud computing and artificial intelligence poses a major climate risk if fueled by high-emission fossil fuels," David Berry, Cloverleaf's CEO, says in a news release. "However, it's also a major opportunity to catalyze the modernization of the US grid and the transition to a smarter and more sustainable electricity system through a novel approach to development.

"Cloverleaf is committed to making this vision a reality with the support of leading climate investors like Sandbrook and NGP."

Berry, who's based in Houston, previously co-founded and served as CFO at ConnectGen and Clean Line Energy Partners, clean energy and transmission developers. Last year, he co-founded Cloverleaf with Seattle-based Brian Janous and CTO Jonathan Abebe, who most recently held a senior role at the United States Department of Energy. Nur Bernhardt, director of Energy Strategy at Microsoft who's also based in Seattle, rounds out the executive team as vice president.

"The large tech companies have become dominant players in the electricity sector, and they are genuinely determined to power their growth with the lowest possible emissions," Janous, who serves as chief commercial officer, says in the release. "Achieving this objective doesn't depend on disruptive new technologies as much as it does on dedicated teams working hand in hand with utility partners to maximize the use of the clean generation, storage, and other technologies we already have."

Cloverleaf will work with regional U.S. utilities and data center operators to provide clean electricity at scale through strategic investments in transmission, grid interconnection, land, onsite power generation, and electricity storage, per the release.

"The sustainable development of digital infrastructure at scale is fundamentally a technical power problem," Alfredo Marti, partner at Sandbrook, adds. "We have witnessed members of the Cloverleaf team effectively address this challenge for many years through a blend of creativity, specialized engineering, a partnership mindset, and astute capital deployment."

Houston resilience tech innovator proves out platform amid Hurricane Beryl

HOUSTON INNOVATORS PODCAST EPISODE 245

Earlier this month, Ali Mostafavi got an unexpected chance to pilot his company's data-backed and artificial intelligence-powered platform — all while weathering one of Houston's most impactful storms.

Mostafavi, a civil and environmental engineering professor at Texas A&M University, founded Resilitix.AI two years ago, and with the help of his lab at A&M, has created a platform that brings publicly available data into AI algorithms to provide its partners near-real time information in storm settings.

As Hurricane Beryl came ashore with Houston on its path, Mostafavi says he had the opportunity to both test his technology and provide valuable information to his community during the storm.

"We were in the process of fine tuning some of our methods and algorithms behind our technology," Mostafavi says on the Houston Innovators Podcast. "When disasters happen, you go to activation mode. We put our technology development and R&D efforts on hold and try to test our technology in an operational setting."

The platform provides its partners — right now, those include local and state organizations and emergency response teams — information on evacuation reports, street flooding, and even damage sustained based on satellite imagery. Mostafavi says that during Beryl, users were wondering how citizens were faring amid rising temperatures and power outages. The Resilitix team quickly pivoted to apply algorithms to hospital data to see which neighborhoods were experiencing high volumes of patients.

"We had the ability to innovate on the spot," Mostafavi says, adding that his own lack of power and internet was an additional challenge for the company. "When an event happens, we start receiving requests and questions. ... We had to be agile and adapt our methods to be responsive. Then at the same time, because we haven't tested it, we have to verify that we are confident (in the information we provide)."

On the episode, Mostafavi shares how Hurricane Harvey — which occurred shortly after Mostafavi moved to Houston — inspired the foundation of Resilitix and how Houston is the ideal spot to grow the company.

"We are very excited that our company is Houston based," he says. "We should not be just ground zero of disasters. We have to also be ground zero for solutions as well. I believe Houston should be the hub for resilience tech innovation as it is for energy transition.

"I think energy transition, climatetech, energy tech, and disaster tech go hand in hand," Mostafavi continues. "I feel that we are in the right place."
