Scientists make significant progress at Harvard Tan-Yang Center thanks to sustained support

Lisa Yang’s unwavering commitment to improving the well-being of others is the common thread that runs through her wide-ranging philanthropic interests. She is particularly invested in improving the lives of people with disabilities and learning differences, having raised two children with autism spectrum disorder (ASD).

In 2019, she and Hock Tan, MBA ’79, gave $20 million to launch the Hock E. Tan and K. Lisa Yang Center for Autism Research at Harvard University, which focuses on the biological basis of neurodevelopment as it relates to ASD. Yang (pictured at right) then made a $4 million gift to establish the Y. Eva Tan Postdoctoral Fellowship at the center in honor of her daughter. Recently, she gave an additional $10 million to bolster the center’s work.

“We are thrilled to have Lisa’s continued support,” says the center’s leader, Michael Greenberg, PhD, the Nathan Marsh Pusey Professor of Neurobiology in the Blavatnik Institute at Harvard Medical School. “We have already made several important discoveries, and we plan to build from those by sharpening our focus."

HMS Dean George Q. Daley, AB ’82, MD ’91, PhD, says he deeply values Yang’s involvement with the School, which includes her service on both the Board of Fellows and the Discovery Council. He expressed thanks for what he described as her “tremendous” gift to fund the Harvard Tan-Yang Center’s next phase of scientific investigation and discovery.

The Harvard center is home to two project teams: the Autism Genetics and Brain Development group, led by Greenberg, and the Sensory Experiences and Social Behavior group. Greenberg and his team have advanced several interconnected questions about the neurobiology of brain development in ASD. They have a longstanding interest in how sensory experiences influence neuronal activity and the development of neural circuits. For the past five years, they have investigated the role of genetic variation in shaping differences in brain development.

“We’ve made significant progress in our understanding of how mutations in ASD genes can cause changes in the expression of activity-dependent genes, and how those changes can alter neural circuit development and plasticity,” Greenberg says.

The Sensory Experiences and Social Behavior group, meanwhile, is focused on ASD patients’ hypersensitivity to sensory stimulation—notably, sensitivity to touch. Group members seek to understand the circuits and pathways in the somatosensory system in mouse models of ASD to better understand the fundamental mechanisms of social touch and, ultimately, social behavior.

“We’re also working to identify biomarkers for touch over-reactivity in patients, as well as new approaches to lessen the burden of touch over-reactivity, with the goal of enhancing the quality of life for those suffering from debilitating forms of sensory over-reactivity,” says group member David Ginty, PhD, the Edward R. and Anne G. Lefler Professor and chair of the Department of Neurobiology.

Both project teams collaborate with peer researchers at the Hock E. Tan and K. Lisa Yang Center for Autism Research at MIT.

“The (Harvard) center has greatly impacted our ability to interact with our MIT colleagues,” says Ginty. “We consider the MIT center our ‘sister center’ with complementary strengths.”

Yang’s recent gift will support the center’s research and the aforementioned fellowship program, which Greenberg says will expand. The program aims to train the next generation of scientists in hopes that the scientific community being built in the center will exist in perpetuity.

“Over the last five years, we have awarded seven outstanding postdoctoral fellows whose research focuses on mechanisms of autism spectrum disorder, and we are delighted to use this new gift to elevate and grow this community of young scientists," Greenberg says.

Yang is exceedingly proud to have supported dozens of fellows through her support of HMS and MIT.

Greenberg and Ginty agree that Tan and Yang’s vision for a unified center of excellence at Harvard dedicated to understanding the neurobiology of ASD has inspired a wave of progress in their collective work.

“We have come together to forge collaborations that would not have existed without their vision, and we have made immense progress in areas of neurobiology that will have a lasting impact in the field of autism spectrum disorder and lead to a better understanding of the ASD experience,” says Ginty.

Harvard Tan-Yang Center research highlights

The Chen Lab

Chinfei Chen, MD ’91, PhD ’91
Professor of neurobiology, HMS

The Chen Lab has found that the synaptic glomerulus in the thalamus plays a crucial role in refining sensory information through experience. The lab identified ASD-related mutations affecting the synaptic glomerulus’s function, leading to altered integration and transmission of sensory information. This research is essential for understanding how impaired information integration in the thalamus contributes to sensory processing symptoms in autism.

The Datta Lab

Sandeep Robert “Bob” Datta, MD ’04, PhD ’04
Professor of neurobiology, HMS

The Datta Lab pioneered the use of machine learning to develop tools for quantitatively evaluating mouse behavior. These tools identify subtle repeated behavioral syllables, enabling researchers to correlate neural activity with real-time free behavior. These tools significantly enhance scientists’ ability to analyze mouse behavior and have the potential to revolutionize the study of genetic and circuit regulation in social behaviors within autism models.

The Ginty Lab

David Ginty, PhD
Edward R. and Anne G. Lefler Professor
and chair of the Department of Neurobiology, HMS

The Ginty Lab highlights the spinal cord’s role in transmitting touch signals to the brain, using ASD mouse models to detail atypical tactile reactions and explore the integration of tactile processing in the spinal cord and brainstem. The lab discovered a direct pathway from skin sensory neurons to the brainstem for high-frequency vibration communication and an indirect pathway to the dorsal horn for encoding pressure intensity. This work is essential for understanding tactile reactivity in individuals with autism.

The Greenberg Lab

Michael Greenberg, PhD
Nathan Marsh Pusey Professor of Neurobiology, HMS

The Greenberg Lab has discovered transcription factor complexes that regulate the development and refinement of neural circuity and are often mutated in ASD. Activity-dependent gene transcription is integral to this process. The lab has identified a novel protein complex that assembles in activated neurons to coordinate inducible gene transcription and dynamically reorganize active neural circuitry. Investigating these factors offers vital insights into autism’s fundamental molecular mechanisms.
