University of Houston College of Optometry Professor John O’Brien has received a $2.6 million grant from the National Eye Institute to continue his research on the retina and neurological functions.

O’Brien is considered a leading expert in retinal neuroscience with more than 20 years of research in the field. The new funding will allow O’Brien and his team to continue to study the dense assembly of proteins associated with electrical synapses, or gap junctions, in the retina.

Gap junctions transfer electrical signals between neurons. And the plasticity of gap junctions changes the strength of a synapse, in turn changing how visual information is processed. Previous research has shown that reduced functions of electrical synapses could be linked to autism, while their hyperfunction may lead to seizures.

“The research we propose will significantly advance our understanding of the molecular complexes that control the function of electrical synapses,” O’Brien said in a news release.

The team at UH will work to identify the proteins and examine how they impact electrical synapses. It is particularly interested in the Connexin 36, or Cx36, protein. According to O’Brien, phosphorylation of Cx36, a short-term chemical modification of the protein, serves as a key driver of plasticity. And the protein has been linked to refractive error development, which is one of the largest vision problems in the world today.

Additionally, OBrien’s research has shown that plasticity is essential for all-day vision, allowing the retina to adjust sensitivity and sharpen images. He has also built a catalog of the core set of proteins surrounding electrical synapses that are conserved across species. His research has been funded by the NEI since 2000.

Houston organization is providing access to special education resources 'anywhere there is Wi-Fi'

Autism Awareness Month

A Houston-based online platform is hoping to provide easy access to special education resources to support individuals with special needs, as well as their employers, teachers, and caregivers — or anyone with internet access.

The online program, Incuentro, launched April 1, coinciding with the start of Autism Awareness Month. The first 15 classes are slated to go live in June. These virtual classes are intended to be a resource for people from first grade all the way through adulthood who are coping with Autism, ADD, Asperger's, social anxiety, or learning differences.

"Over 30 students participated in the pilot program over the past 9 months," says Wendy Dawson, founder of Incuentro. "I've seen students relate to the lessons, make connections with the topics, engage in peer conversation, and find support and learning in a safe environment."

Students learn and practice skills applicable to school, employment, and social situations in the virtual company of a qualified teacher and peers from the comfort of their own home. The teaching style is as interactive as possible and requires participants to engage in discussion.

Life education
Dawson says that students will get the most out of this experience if they are verbal, able to sustain attention, and participate in a video conference forum. Hour-long classes focus on friendship, behavior, social interactions in the primary and elementary years, while tweens focus on making peer connections.

"We want to provide help upfront to reduce the anxiety and depression that we commonly see later in life," Dawson says.

Teen classes set up students with skills for future employment and transitions post-high school. Adult learners benefit from job skills and workplace behavior norms.

Students who are employed or looking for employment learn about topics like conversing with coworkers and supervisors, appropriate social interactions, and understanding the rules of the workplace. Equally important, teachers discuss with participants ways that they can be their own advocate as they maneuver through society.

A focus on inclusion
Incuentro offers employer training as well, to help foster a climate of inclusion in the workplace, to discourage a lowering of expectations when accommodating employees with Autistic traits. Classes give supervisors understanding and practicalities that will foster a positive environment for employees who are also enrolled in the course.

"Employers are coached on topics such as: understanding a literal mind, being factual, making simple accommodations like visual schedules, delivering information in a low-stress manner, and understanding learning styles," Dawson says.

Incuentro helps to bridge the gap between the service and people in need through technology.

"There is a huge disconnect between the people who need services, and the actual resources. Many times they don't know where to go, or are too far away to access them."

All you need is internet access
Accessing the classes remotely removes the barrier of accessibility for people in rural areas, as well as people who would rather not drive to a class after a long day at work or school. Oftentimes, students will feel more comfortable participating in a one-hour, online discussion with 5-7 peers, rather than enduring the social pressures of a classroom setting.

"Our desire is to bring access to special education expertise to anywhere there is Wi-Fi," says Dawson.

Incuentro curriculum is created by Education Visionary Specialist Brandi Timmons, a Board Certified Behavior Analyst (BCBA) and a Licensed Behavior Analyst (LBA). Classes are taught by expert teachers who specialize in special needs education.

Family business
Dawson's passion behind Incuentro was inspired by her step-son, Cameron Dawson, who was diagnosed with Autism at the age of two.

"There were no services to fit his needs available in the market," Dawson says, "so we've spent 10 years advocating and learning, and figuring out how to best bring services to people who need them."

Cameron participated in the Incuentro pilot program while attending Texas Tech, and in May he will be graduating with his degree in Communication Studies. Upon returning home to Houston, he will be seeking a job in one of many local churches, where Dawson says he has experienced love and support throughout his life.

As a mother of a child with Autism and advocate for people with special needs, Dawson has seen the challenges faced by parents. Parents not only must navigate the ups and downs of school life and home life with their child each step of the way, but also plan next steps past high school graduation, and long-term care, if necessary. Incuentro helps to facilitate the discussion and provide resources for caregivers wanting to learn what options are available.

With April designated as Autism Awareness Month, Incuentro seeks to partner with organizations serving special needs populations, such as school districts, health clinics, or Autism support networks, and reach the people who need it most. Incuentro has pledged to donate a portion of its profits to a Houston non-profit that offers in-person classes for people with special needs, Social Motion. At its heart, Incuentro intends to be an answer to the question: how do we set individuals with special needs up for success, and help give them the tools to live an independent and fulfilling life?

UH lands $4M NIH grant to study early signs of autoimmune disease

NIH funding

The University of Houston recently received a $4 million National Institutes of Health grant to support a 10-year longitudinal study to identify the earliest biological markers of autoimmune disease.

Led by Chandra Mohan, the Hugh Roy and Lillie Cranz Cullen Endowed Professor of Biomedical Engineering, the study aims to examine what causes Systemic Autoimmune Rheumatic Diseases (SARDs) and to identify targets for future treatments. The study will be carried out in collaboration with Dr. Karen Costenbader at Harvard Medical School, Boston.

SARDs include conditions like rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome and systemic sclerosis—all are considered chronic diseases currently without a cure. Autoimmune diseases affect over 30 million people globally, according to UH.

SARDs occur when the body’s immune system attacks healthy, non-threatening tissues and organs. According to UH, in these diseases, the body often attacks nuclear antigens, creating anti-nuclear autoantibodies, which can be early detection signs for SARDs in more than 50 percent of patients, Mohan says.

Researchers will study blood samples and environmental exposure over the 10 years to better understand anti-nuclear autoantibodies.

“Collectively, these studies will help identify the genetic, environmental and cellular factors that are operative at the two steps of SARD development, namely the emergence of anti-nuclear autoantibodies and disease onset,” Mohan said in a news release. “ More importantly, these studies will highlight functional molecular pathways and mechanisms that may be operative at each step."

Mohan predicts that looking at SARDs’ shared characteristics, rather than each disease individually, could help identify more treatment methods.

“Individual SARDs have been examined in silos without an attempt to discern shared underlying features at the molecular level,” he added in the release. “Current understanding of the initial (and likely shared) origins of SARDs is only rudimentary but urgently needed to develop means for prevention and treatment.”

Earlier this year, UH also received an $11 million NIH grant to conduct a first-of-its-kind study of early language development in children ages 18 to 24 months. Read more here.

New Texas Stock Exchange officially begins trading in Dallas

Welcome to Y'all Street

Two-step aside, New York Stock Exchange and Nasdaq. The Dallas-based Texas Stock Exchange, nicknamed Y’all Street, just kicked off live trading with five stocks — and lots of Lone Star ambition.

“The Texas Stock Exchange aims to revitalize competition for [stock] issuers, establish the premier venue for listings, and create a world-class trading platform for all market participants,” the exchange says in a fact sheet.

The exchange — whose Texas-influenced nickname is a nod to New York City’s Wall Street — has collected at least $275 million in investments. The roughly 90 financial backers of TXSE include Bank of America, BlackRock, Charles Schwab, Citadel Securities, Dell Family Office, Fortress, Goldman Sachs, and JPMorgan Chase.

Representatives of TXSE couldn’t be reached for comment. On its website, the exchange calls itself “the most well-capitalized equities exchange to ever be approved” by the U.S. Securities and Exchange Commission (SEC).

Not to be outdone, NYSE has launched Dallas-based NYSE Texas and Nasdaq has expanded its presence in Dallas.

Y’all Street adds to Dallas-Fort Worth’s rising status as a major hub for financial services, with The Wall Street Journal naming North Texas the country’s second biggest financial hub after New York City.

“A homegrown national exchange means more jobs, more investment, and more growth opportunities for businesses and communities across the Lone Star State,” Gabriela von zur Muehlen, senior vice president and chief policy officer at the Texas Association of Business, told The Texas Tribune.

Bulent Temel, an associate professor of practice in economics at the University of Texas at San Antonio, told Texas Standard that TXSE “is going to boost the credibility of the Texas economy.”

Texas’ estimated gross domestic product (GDP), a yardstick for the size of an economy, climbed to a record-setting $2.9 trillion in 2025, making it the state with the second highest GDP after California. DFW’s estimated GDP in 2023 stood at $744.6 billion, eclipsing the GDP of many countries.

“The center of gravity for American capitalism is now headquartered in the Boom Belt,” Abbott proclaimed in April, referring to an 11-state region (including Texas) in the South and Southeast that’s seeing tremendous economic and population growth. “The Texas Stock Exchange is the natural extension of that capitalism. It ensures that capital markets will reflect the quadrant that is driving American growth.”

Orion vehicle manager reflects on Artemis II, looks to 2028 moon mission

Q&A

Humanity is finally headed back to the moon after more than half a century. This year's launch of the Artemis II mission in the Orion spacecraft put four crew members in lunar orbit and tested the new ship developed by Lockheed Martin.

Everything went smoothly, safely returning astronauts home, but there is always room to improve. InnovationMap chatted via email with Orion vehicle manager Branelle Rodriguez, shortly after a talk at The Ion, for insight on how Orion might perform in the future as the next lunar landing approaches in early 2028.

InnovationMap: How satisfied are you with the way Orion operated on this past mission?

Branelle Rodriguez: Orion performed exceptionally well during Artemis II, successfully demonstrating critical spacecraft capabilities, including life support systems, displays and controls, and executing manual piloting operations. Artemis II brought humans back to the moon, achieving key exploration and scientific imagery, while validating systems essential for future Artemis missions.

IM: What is the most important thing you learned about improving Orion for the next mission?

BR: The Artemis II mission provided invaluable insights into crew operations and spacecraft performance in a deep-space environment. With every mission, NASA applies lessons learned to continuously improve Orion’s operations, validate design and ensure mission readiness. Artemis II offered our first opportunity to evaluate several new systems and gain a deeper understanding of what it is like for astronauts to live and work inside the spacecraft. The operational, technical and human factors data collected are being integrated across the program to refine future missions, reduce risk and enhance overall mission success.

IM: How has Orion helped the mission to explore space?

BR: Orion is one of NASA’s foundational elements for human deep space exploration—not only supporting the mission but serving as a core component of it. It is currently the only spacecraft capable of carrying crew on deep space missions and returning them safely to Earth from the high speeds required from the vicinity of the moon. No other spacecraft has the technology to endure the extremes that come with human deep-space travel, such as advanced environmental and life support, navigation, communications, radiation shielding, and the world’s largest ablative heat shield to protect the astronauts during reentry into Earth’s atmosphere. Orion has already taken astronauts to explore space farther than ever before—252,756 miles from Earth— and will carry crews to the moon on future missions to explore the lunar South Pole region. The astronauts’ observations, samples, and data collected on these future missions will expand our understanding of our solar system and home planet.
