All though career technologist Kelly Pracht began her entrepreneurial journey with her favorite sport, baseball, she's recently expanded the data-backed, fan-engaging sports betting platform to new sports.

Pract, who spent nearly 20 years designing technologies at Hewlett Packard Enterprise, founded nVenue in 2019 after realizing that, while there's endless data and stats available in baseball, there's nothing that exists for fans to engage in that data in real time. So, she set out to build it herself.

At first, the platform launched as a direct-to-fans platform, but Pracht says on the Houston Innovators Podcast that the company pivoted to B-to-B amid its participation in the Comcast SportsTech accelerator.

"The industry was super hungry for fan engagement and sports betting, and we were one of the only companies that could do it," she says on the show. "We found this huge product-market fit of the whole industry wanting ways to engage and bet in real time." Read more.

Two Houston organizations announced a new collaboration in a major move for Houston’s biotech scene.

Fannin Partners and the University of Texas MD Anderson Cancer Center have teamed up to develop drugs based on Raptamer, the creation of Fannin company Radiomer Therapeutics.

“Raptamers combine antibody level affinities with desirable physical and pharmacokinetic properties, and a rapid path to clinic,” Dr. Atul Varadhachary, CEO of Radiomer Therapeutics and Fannin managing partner, Varadhachary, explained to InnovationMap in May. “We are deploying this unique platform to develop novel therapies against attractive first-in-class oncology targets.” Read more.

Earlier this year, Varadhachary joined the Houston Innovators Podcast to discuss Fannin's innovation approach and contribution to medical development in Houston. Listen to the episode below.

Since the force of COVID-19 hit globally in 2020, scientists have made efficient progress in the fight against it. As Dr. Navin Varadarajan puts it, vaccines have “allowed us to become a society again.”

And he should know, the M.D. Anderson Professor of William A. Brookshire Chemical and Biomolecular Engineering at University of Houston just published back-to-back studies for nasal sprays that combat viruses. One, the NanoSTING therapeutic, has proven effective in treating strains of SARS-CoV-2 and the flu virus. The other, NanoSTING-NS Pan-coronavirus Vaccine is targeted at preventing the transmission of multiple COVID variants altogether.

Why a nasal vaccine? Varadarajan explains that while COVID vaccines prevent advanced disease, they don’t prevent transmission.

“Intramuscular vaccines do not facilitate a component of peer immunity called mucosal immunity, which takes care of these points of entries, these wet surfaces, which can be of the nose and the wet surfaces of the nose, and so they don't prevent transmission,” he tells InnovationMap. “So I can be vaccinated, I pick up a small infection that's confined largely to my nostrils, and I can still pass it on to vulnerable people, the aged, the immunocompromised people who have all the drugs they're taking to fight other things, like cancer patients. And so for them, the vaccines tend to be less efficacious, and if I transfer it to them, unfortunately they can end up in a hospital, right? And so preventing transmission is the way to end this cycle.” Read more.

making moves

T-cell immunotherapy is all the rage in the world of fighting cancer. A Houston company’s researchers have discovered a new subset of T cells that could be a game changer for patients.

CellChorus is a spinoff of Navin Varadarajan’s Single Cell Lab, part of the University of Houston’s Technology Bridge. The lab is the creator of TIMING, or Time-lapse Imaging Microscopy In Nanowell Grids. It’s a visual AI program that allows scientists to understand the functions of cells by evaluating cell activation, killing, and movement.

Last month, Nature Cancer published a paper co-authored by Varadarajan entitled, “Identification of a clinically efficacious CAR T cell subset in diffuse large B cell lymphoma by dynamic multidimensional single-cell profiling.”

“Our results showed that a subset of T cells, labeled as CD8-fit T cells, are capable of high motility and serial killing, found uniquely in patients with clinical response,” says first author and recent UH graduate Ali Rezvan in Nature Cancer.

Besides him and Varadarajan, contributors hail from Baylor College of Medicine/Texas Children’s Hospital, MD Anderson Cancer Center, Kite Pharma, and CellChorus itself.

The team identified the CD80-fit T cells using TIMING to examine interactions between T cells and tumor cells across thousands of individual cells. They were able to integrate the results using single-cell RNA sequencing data.

T-cell therapy activates a patient’s own immune system to fight cancer cells, but not every patient responds favorably to it. Identifying CD8-fit cells could be the key to manufacturing clinical response even in those for whom immunotherapy hasn’t been effective.

“This work illustrates the excellence of graduate students Ali Rezvan and Melisa Montalvo; and post-doctoral researchers Melisa Martinez-Paniagua and Irfan Bandey among others,” says Varadarajan in a statement.

Earlier last month, CellChorus recently received a $2.5 million SBIR grant. The money allows the company to share TIMING more widely, facilitating even more landmark discoveries like CD8-fit cells.

They say it’s all in the timing. For CellChorus, it’s all in the TIMING. That’s Time-lapse Imaging Microscopy In Nanowell Grids. TIMING is a visual AI program that evaluates cell activation, killing and movement, which allows scientists to better understand how cells function.

The technology is important to the development of novel therapies in the realms of oncology, infectious diseases, and countless other disorders and diseases. By allowing scientists to observe those maladies at their roots, it will enable them to create, and ultimately deliver new medications and other therapies faster, at lower cost, and with a higher success rate.

CellChorus is a spinoff of the Single Cell Lab at the University of Houston. Part of UH’s Technology Bridge, CEO Daniel Meyer connected with co-founder and leader of Single Cell Lab, Navin Varadarajan, through co-founder Laurence Cooper.

“The company had been established, but there were limited operations,” recalls Meyer during a phone call with InnovationMap.

That was the fall of 2020. Now, the team has just announced a $2.3 million SBIR (Small Business Innovation Research) Fast-Track grant from the National Institute of General Medical Sciences.

“This funding will support development of a product offering that builds on the success of our early access laboratory,” Cooper said in a press release. “As the next frontier of cellular analysis, dynamic single-cell analysis will increase the impact that immunotherapies have in improving the lives of patients.”

Meyer is based in the Bay Area, but the rest of the team is in Houston. Meyer has a proven track record as an investor and early stage entrepreneur in life sciences companies, including work as COO of Genospace, which was acquired by HCA Healthcare.

Meyer says that what attracted him to CellChorus was a combination of a clear need for the technology and the fact that it was “very well validated.“

“Developers of immunotherapies need better functional data earlier so that they can develop and deliver better therapies,” he explains.

Another aspect of its appeal was the fact that more than 10 publications featured data from the TIMING platform.

“We’ve had both large and small biopharmas publish data,” says Meyer. “That’s important as well because it shows there’s applicability in both nonprofit and for-profit research.”

Though Meyer himself doesn’t currently live in Houston, he recognizes its importance to CellChorus. He says that it can be difficult for an early stage company to find appropriate lab space, so Technology Bridge was of exceptional importance for CellChorus. Since opening the lab a year and a half ago, Varadarajan and his team have been busy.

“Example projects we have completed include understanding mechanism of action for cell therapy products, selecting lead candidates for T cell engagers, identifying biomarkers of response to cell therapies, and quantifying potency and viability for cell therapy manufacturing technologies,” says Meyer.

And now, CellChorus is collaborating with leaders in the industry.

“These include top-25 biopharmaceutical companies and promising venture-backed biotechnology companies, as well as leading not-for-profit research institutions,” says Meyer in a press release. It’s clear that the TIMING is right for CellChorus to excel.

COOGS TACKLE COVID

A major Houston university has taken a big leap in the race to battle debilitating diseases such as COVID-19. The University of Houston has entered into an exclusive license option agreement with AuraVax Therapeutics Inc., a Houston-based biotech company developing novel vaccines against aggressive respiratory diseases such as coronavirus, according to a press release.

This means AuraVax has the option to exclusively license a new intranasal COVID-19 vaccine technology developed by Navin Varadarajan, an M.D. Anderson professor of chemical and biomolecular engineering. Varadarajan is a co-founder of AuraVax.

The vaccine is a nasal inhalant, much like FluMist. Based on pre-clinical experimentation, Varadarajan reports his technology not only elicits a mucosal immune response, but also systemic immunity, according to UH.

"We plan to stop COVID-19, a respiratory virus, at its point of entry — the nasal cavity — and we believe our intranasal platform is a differentiated approach that will lead to a vaccine with increased efficacy to create sustained immunity to COVID-19," said Varadarajan in a statement.

So how does it work? Varadarajan is utilizing the spike protein, which helps the virus enter the target cell, and is the major target for neutralizing antibodies as it binds to the ACE 2 cellular receptor, for virus entry. The professor prefers using proteins because of their ability to induce strong immune responses, flexibility and scalability, and the absence of infectious particles, per UH.

Varadarajan's company, AuraVax, has created a next-generation vaccine platform that combines the potential of in-home administration with the ability to deliver complete immunity. The technology has been validated for COVID-19 in initial animal studies and results in immunity measured by both B-cell and T-cell responses.

"We believe AuraVax has a competitive advantage given the immune responses and a supply chain that is well-suited for widespread distribution and self-administration distribution," said Varadarajan. "We are excited to be collaborating with the University of Houston and look forward to future success by advancing the development of this novel intranasal vaccine technology to address a multitude of respiratory viruses, starting with COVID-19."

University of Houston researchers studying COVID-19 prevention and treatment

research roundup

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.

UH study uncovers sustainable farming methods for hemp production

growth plan

A new University of Houston study of hemp microbes can potentially assist scientists in creating special mixtures of microbes to make hemp plants produce more CBD or have better-quality fibers.

The study, led by Abdul Latif Khan, an assistant professor of biotechnology at the Cullen College of Engineering Technology Division, was published in the journal Scientific Reports from the Nature Publishing Group. The team also included Venkatesh Balan, UH associate professor of biotechnology at the Cullen College of Engineering Technology Division; Aruna Weerasooriya, professor of medicinal plants at Prairie View A&M University; and Ram Ray, professor of agronomy at Prairie View A&M University.

The study examined microbiomes living in and around the roots (rhizosphere) and on the leaves (phyllosphere) of four types of hemp plants. The team at UH compared how these microorganisms differ between hemp grown for fiber and hemp grown for CBD production.

“In hemp, the microbiome is important in terms of optimizing the production of CBD and enhancing the quality of fiber,” Khan said in a news release. “This work explains how different genotypes of hemp harbor microbial communities to live inside and contribute to such processes. We showed how different types of hemp plants have their own special groups of tiny living microbes that help the plants grow and stay healthy.”

The study indicates that hemp cultivation can be improved by better understanding these distinct microbial communities, which impact growth, nutrient absorption, stress resilience, synthesis and more. This could help decrease the need for chemical inputs and allow growers to use more sustainable agricultural practices.

“Understanding these microorganisms can also lead to more sustainable farming methods, using nature to boost plant growth instead of relying heavily on chemicals,” Ahmad, the paper’s first author and doctoral student of Khan’s, said the news release.

Other findings in the study included higher fungal diversity in leaves and stems, higher bacterial diversity in roots and soil, and differing microbiome diversity. According to UH, CBD-rich varieties are currently in high demand for pharmaceutical products, and fiber-rich varieties are used in industrial applications like textiles.

Tom Hanks touches down at Space Center Houston for lunar film premiere

To The Moon

The Artemis Exhibit at Space Center Houston shimmered with star power as nearly 500 insiders gathered for an out-of-this-world affair celebrating the premiere of The Moonwalkers: A Journey with Tom Hanks. The immersive cinematic experience, narrated and co-written by Oscar-winning actor Tom Hanks, offers guests a front-row seat to the triumphs of past lunar missions and a look ahead to NASA’s Artemis era.

The VIP reception brought a celestial twist to the traditional cocktail hour. Guests were served shrimp and oysters, along with potato croquettes paired with peach gastrique, a playful nod to the first vegetable grown in space and the first fruit consumed on the Moon. Espresso martinis featuring Hanks’ coffee brand, Hanx, were shaken and served.

Inside the newly renovated Space Center Theater, a 270-degree projection mapping spectacle brought The Moonwalkers to life. The film weaves rare astronaut interviews with behind-the-scenes glimpses into the upcoming Artemis missions.

Following the screening, a panel discussion brought the experience back to Earth. William T. Harris, Space Center Houston president and CEO, moderated a conversation with Tom Hanks, Apollo 16 moonwalker Charlie Duke, and Artemis II astronauts Victor Glover, Christina Koch, and Reid Wiseman. Together, they explored the film’s themes and what lies ahead as humanity returns to the Moon.

The Moonwalkers: A Journey with Tom Hanks is now on view at Space Center Houston. The immersive show is included in the general admission price. It runs 50 minutes and showings begin on the half hour, starting at 10:30 am.

Houston space org to launch experiments aboard first mission into polar orbit

all aboard

Houston's Translational Research Institute for Space Health, or TRISH, will send its latest experiments into space aboard the Fram2 mission, the first all-civilian human spaceflight mission to launch over the Earth’s polar regions.

Fram2, operated by SpaceX, is targeting to launch Monday, March 31, at NASA’s Kennedy Space Center in Florida. The crew of four is expected to spend several days in polar orbit aboard the SpaceX Dragon spacecraft in low Earth orbit. TRISH’s research projects are among 22 experiments that the crew will conduct onboard.

The crew's findings will add to TRISH's Enhancing eXploration Platforms and ANalog Definition, or EXPAND, program and will be used to help enhance human health and performance during spaceflight missions, including missions to the moon and Mars, according to a release from TRISH.

“The valuable space health data that will be captured during Fram2 will advance our understanding of how humans respond and adapt to the stressors of space,” Jimmy Wu, TRISH deputy director and chief engineer and assistant professor in Baylor’s Center for Space Medicine, said in the release. “Thanks to the continued interest in furthering space health by commercial space crews, each human health research project sent into orbit brings us closer to improving crew member well-being aboard future spaceflight missions.”

The six TRISH projects on Fram2 include:

  • Cognitive and Physiologic Responses in Commercial Space Crew on Short-Duration Missions, led by Dr. Mathias Basner at the University of Pennsylvania Perelman School of Medicine. The crew will wear a Garmin smartwatch and a BioIntelliSense BioButton® medical grade device to track cognitive performance, including memory, spatial orientation, and attention before, during, and after the mission.
  • Otolith and Posture Evaluation II, led by Mark Shelhamer at Johns Hopkins University. The experiment will look at how astronauts’ eyes sense and respond to motion before and after spaceflight to better understand motion sickness in space.
  • REM and CAD Radiation Monitoring for Private Astronaut Spaceflight, led by Stuart George at NASA Johnson Space Center. This experiment will test space radiation exposure over the Earth’s north and south poles and how this impacts crew members.
  • Space Omics + BioBank, led by Richard Gibbs and Harsha Doddapaneni at Baylor College of Medicine. The experiment will use Baylor’s Human Genome Sequencing Center's Genomic Evaluation of Space Travel and Research program to gain insights from pre-flight and post-flight samples from astronauts.
  • Standardized research questionnaires, led by TRISH. The test asks a set of standardized research questionnaires for the crew to collect data on their sleep, personality, health history, team dynamics and immune-related symptoms.
  • Sensorimotor adaptation, led by TRISH. The project collects data before and after flight to understand sensorimotor abilities, change and recovery time to inform future missions to the moon.

TRISH, which is part of BCM’s Center for Space Medicine with partners Caltech and MIT, has launched experiments on numerous space missions to date, including Blue Origin's New Shepard rocket last November and Axiom Space's Ax-3 mission to the International Space Station last January.
