Sesh Coworking, described as Houston’s first female-focused and LGBTQIA+ affirming coworking, has been operating its 2808 Caroline Street location's second-floor space since January, but the first floor, as of this week, is now open to membership and visitors. The new build-out brings the location to over 20,000 square feet of space.

Called The Parlor, the new space includes additional desks, common areas, a wellness room, and a retail pop-up space. Since its inception in early 2020, Sesh has overcome the pandemic-related obstacles in its path and even seen a 60 percent increase in membership with an overall 240 percent increase in sales over the past year.

“Our growth is a testament to the ever-changing landscape of Houston’s office and retail industry after the workplace dramatically changed in 2020,” says Maggie Segrich, co-founder of Sesh Coworking, in a news release. “We are ecstatic to welcome current and prospective members to our new, inclusive space.” Click here to read more.

A Houston researcher is developing a cancer treatment — called oncolytic virotherapy — that can kill cancer cells while being ineffective to surrounding cells and tissue. Basically, the virus targets the bad guys by "activating an antitumor immune response made of immune cells such as natural killer (NK) cells," according to a news release from the University of Houston.

However exciting this rising OV treatment seems, the early stage development is far from perfect. Shaun Zhang, director of the Center for Nuclear Receptors and Cell Signaling at the University of Houston, is hoping his work will help improve OV treatment and make it more effective.

“We have developed a novel strategy that not only can prevent NK cells from clearing the administered oncolytic virus, but also goes one step further by guiding them to attack tumor cells. We took an entirely different approach to create this oncolytic virotherapy by deleting a region of the gene which has been shown to activate the signaling pathway that enables the virus to replicate in normal cells,” Zhang says in the release.

University of Houston researchers snag $1.8M to develop cancer-fighting virus

immunotherapy innovation

Viruses attack human cells, and that's usually a bad thing — some Houston researchers have received fresh funding to develop and use the evil powers of viruses for good.

The developing cancer treatment is called oncolytic virotherapy and has risen in popularity among immunotherapy research. The viruses can kill cancer cells while being ineffective to surrounding cells and tissue. Basically, the virus targets the bad guys by "activating an antitumor immune response made of immune cells such as natural killer (NK) cells," according to a news release from the University of Houston.

However exciting this rising OV treatment seems, the early stage development is far from perfect. Shaun Zhang, director of the Center for Nuclear Receptors and Cell Signaling at the University of Houston, is hoping his work will help improve OV treatment and make it more effective.

“We have developed a novel strategy that not only can prevent NK cells from clearing the administered oncolytic virus, but also goes one step further by guiding them to attack tumor cells. We took an entirely different approach to create this oncolytic virotherapy by deleting a region of the gene which has been shown to activate the signaling pathway that enables the virus to replicate in normal cells,” Zhang says in the release.

Zhang, who is also a M.D. Anderson professor in the Department of Biology & Biochemistry, has received a $1.8 million grant from the National Institutes of Health to continue his work.

Zhang and his team are specifically creating a new OV — called FusOn-H2 and based on the Herpes simplex 2 virus.

“Our recent studies showed that arming FusOn-H2 with a chimeric NK engager (C-NK-E) that can engage the infiltrated natural killer cells with tumor cells could significantly enhance the effectiveness of this virotherapy,” he says. “Most importantly, we observed that tumor destruction by the joint effect of the direct oncolysis and the engaged NK cells led to a measurable elicitation of neoantigen-specific antitumor immunity.”

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.

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.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
