The Bedari Foundation, established by philanthropists Jennifer and Matthew C. Harris, has given $20 million to the UCLA College to establish the UCLA Bedari Kindness Institute.

The institute, which is housed in the division of social sciences, will support world-class research on kindness, create opportunities to translate that research into real-world practices, and serve as a global platform to educate and communicate its findings. Among its principal goals are to empower citizens and inspire leaders to build more humane societies.

“Universities should always be places where we teach students to reach across lines of difference and treat one another with empathy and respect — even when we deeply disagree,” UCLA Chancellor Gene Block said. “The UCLA Bedari Kindness Institute will bring the best thinking to this vital issue and, I think, will allow us to have a real social impact on future generations.”

The institute, which will begin operating immediately, will take an interdisciplinary approach to understanding kindness — through evolutionary, biological, psychological, economic, cultural and sociological perspectives. It will focus on research about the actions, thoughts, feelings and social institutions associated with kindness and will bring together researchers from across numerous disciplines at UCLA and at external organizations.

The inaugural director of the institute is Daniel Fessler, a UCLA anthropology professor whose research interests include exploring how witnessing acts of remarkable kindness can cause an uplifting emotional experience that in turn motivates the observer to be kind. Studies by Fessler and his colleagues have shed light on why some people are open to that type of “contagious kindness” experience.

The Bedari Foundation is a private family foundation whose aim is to enable significant cultural shifts in the fields of health and wellness, community displacement and environmental conservation.

“Our vision is that we will all live in a world where humanity discovers and practices the kindness that exists in all of us,” said Matthew Harris, the foundation’s co-founder and a 1984 UCLA graduate. “Much research is needed to understand why kindness can be so scarce in the modern world. As we seek at Bedari to bridge the divide between science and spirituality, through the establishment of the UCLA Bedari Kindness Institute we hope to educate and empower more and more people in the practice of kindness.”

Already, a range of researchers at UCLA are studying the types of questions that will be the basis of the institute’s work. For example, UCLA anthropologists are examining how kindness spreads from person to person and group to group. UCLA sociologists are analyzing how people who regularly act unkind might be encouraged to engage in kind acts instead, and UCLA psychologists are researching how kindness can improve people’s moods and reduce symptoms of depression. Others are pursuing research on changes in neurobiology and behaviors resulting from mindfulness, and how those changes can influence kindness and people’s mental, physical and social well-being.

“In the midst of current world politics, violence and strife, the UCLA Bedari Kindness Institute seeks to be an antidote,” said Darnell Hunt, dean of the UCLA division of social sciences. “Rooted in serious academic work, the institute will partner and share its research on kindness broadly in accessible formats. The Bedari Foundation’s extraordinary gift is truly visionary and we are grateful for its support and leadership.”

The Kindness Institute will provide seed funding for research projects that examine the social and physical mechanics of kindness and how kindness might be harnessed to create more humane societies. It also will provide mindfulness awareness training to students, faculty and staff and in underserved Los Angeles communities, and host an annual conference at which presenters will examine new discoveries in kindness research, among other activities.

“The mission of the Kindness Institute perfectly aligns with that of the division of social sciences, where engaging the amazing diversity and social challenges shaping Los Angeles routinely inspires research that has the potential to change the world,” Hunt said.

The gift is part of the Centennial Campaign for UCLA, which is scheduled to conclude in December.

Study shows how serotonin and a popular anti-depressant affect the gut’s microbiota

A new study in mice led by UCLA biologists strongly suggests that serotonin and drugs that target serotonin, such as anti-depressants, can have a major effect on the gut’s microbiota — the 100 trillion or so bacteria and other microbes that live in the human body’s intestines.

Serotonin — a neurotransmitter, or chemical messenger that sends messages among cells — serves many functions in the human body, including playing a role in emotions and happiness. An estimated 90% of the body’s serotonin is produced in the gut, where it influences gut immunity.

The team — led by senior author Elaine Hsiao and lead author Thomas Fung, a postdoctoral fellow — identified a specific gut bacterium that can detect and transport serotonin into bacterial cells. When mice were given the antidepressant fluoxetine, or Prozac, the biologists found this reduced the transport of serotonin into their cells. This bacterium, about which little is known, is called Turicibacter sanguinis. The study is published this week in the journal Nature Microbiology.

“Our previous work showed that particular gut bacteria help the gut produce serotonin. In this study, we were interested in finding out why they might do so,” said Hsiao, UCLA assistant professor of integrative biology and physiology, and of microbiology, immunology and molecular genetics in the UCLA College; and of digestive diseases in the David Geffen School of Medicine at UCLA.

Hsiao and her research group reported in the journal Cell in 2015 that in mice, a specific mixture of bacteria, consisting mainly of Turicibacter sanguinis and Clostridia, produces molecules that signal to gut cells to increase production of serotonin. When Hsiao’s team raised mice without the bacteria, more than 50% of their gut serotonin was missing. The researchers then added the bacteria mixture of mainly Turicibacter and Clostridia, and their serotonin increased to a normal level.

That study got the team wondering why bacteria signal to our gut cells to make serotonin. Do microbes use serotonin, and if so, for what?

In this new study, the researchers added serotonin to the drinking water of some mice and raised others with a mutation (created by altering a specific serotonin transporter gene) that increased the levels of serotonin in their guts. After studying the microbiota of the mice, the researchers discovered that the bacteria Turicibacter and Clostridia increased significantly when there was more serotonin in the gut.

If these bacteria increase in the presence of serotonin, perhaps they have some cellular machinery to detect serotonin, the researchers speculated. Together with study co-author Lucy Forrest and her team at the National Institutes of Health’s National Institute of Neurological Disorders and Stroke, the researchers found a protein in multiple species of Turicibacter that has some structural similarity to a protein that transports serotonin in mammals. When they grew Turicibacter sanguinis in the lab, they found that the bacterium imports serotonin into the cell.

In another experiment, the researchers added the antidepressant fluoxetine, which normally blocks the mammalian serotonin transporter, to a tube containing Turicibacter sanguinis. They found the bacterium transported significantly less serotonin.

The team found that exposing Turicibacter sanguinis to serotonin or fluoxetine influenced how well the bacterium could thrive in the gastrointestinal tract. In the presence of serotonin, the bacterium grew to high levels in mice, but when exposed to fluoxetine, the bacterium grew to only low levels in mice.

“Previous studies from our lab and others showed that specific bacteria promote serotonin levels in the gut,” Fung said. “Our new study tells us that certain gut bacteria can respond to serotonin and drugs that influence serotonin, like anti-depressants. This is a unique form of communication between bacteria and our own cells through molecules traditionally recognized as neurotransmitters.”

The team’s research on Turicibacter aligns with a growing number of studies reporting that anti-depressants can alter the gut microbiota. “For the future,” Hsiao said, “we want to learn whether microbial interactions with antidepressants have consequences for health and disease.” Hsiao wrote a blog post for the journal about the new research.

Other study co-authors are Helen Vuong, Geoffrey Pronovost, Cristopher Luna, Anastasia Vavilina, Julianne McGinn and Tomiko Rendon, all of UCLA; and Antoniya Aleksandrova and Noah Riley, members of Forrest’s team.

The research was supported by funding from the National Institutes of Health’s Director’s Early Independence Award, Klingenstein-Simons Fellowship Award, and David & Lucile Packard Foundation’s Packard Fellowship for Science and Engineering.
