Brain-Infiltrating T Cells Linked to Social Deficits in Autism Mouse Model
The prevalence of autism spectrum disorder (ASD) is roughly one in 36 people, with a male-to-female ratio of 4:1. The disorder is known to be influenced by multiple factors, both genetic (gene mutations and copy number variations) and environmental, such as infections during pregnancy. However, the role of immunity in genetic ASD remains unclear.
One area of interest lies in lymphocytes—cells that are known to shape neurodevelopment and behavior. But their roles in neurodevelopmental disorders are not well defined.
Now, new research shows that a subset of T cells—γδ T cells—can infiltrate the brain and contribute to changes in social behavior in a genetic mouse model that mimics behavioral features of ASD. Depleting these cells from the brain increased sociability, suggesting that targeting abnormal immune function during neurodevelopment may offer interventions for ASD.
This work is published in Science Immunology in the paper, “CXCL16-mediated recruitment of γδ T cells to the brain reduces sociability in mice.”
Infections during pregnancy can induce the release of interleukin-17A (IL-17A) from T helper 17 cells and γδ T cells. Prior research has linked this type of maternal immune activation to neurodevelopmental disorders, but there is a lack of evidence connecting IL-17A and social behaviors in genetic mouse models.
To investigate this further, a team of researchers from the Division of Allergy and Immunology in the Medical Institute of Bioregulation at Kyushu University, in Fukuoka, Japan, studied 15q11-13 duplication (15q dup) mice—a mouse model that mimics a chromosome duplication found in some humans with ASD. These mice also demonstrate reduced social interactions, behavioral inflexibility, and increased anxiety-like behaviors.
The team analyzed immune cell populations in the brains of the 15q dup mice. Their findings suggest an increase in γδ T cells in the developing brains when compared with wild-type mice.
Using single-cell RNA sequencing (scRNA-seq), the team uncovered that this was most likely due to microglia in the brain expressing the chemokine CXCL16, which promotes immune cell migration. CXCL16 was highly expressed in the brains of 15q dup mice and contributed to increased infiltration of γδ T cells.
In addition, experiments revealed that deleting IL-17A–producing γδ T cells or blocking them with antibodies after birth increased sociability and reduced anxiety-like behaviors in the 15q dup mice.
Taken together, the authors note that these findings suggest that “immune dysregulation contributes to social behavior deficits in 15q dup mice, consistent with observations in maternal immune activation models, and may represent a potential target for interventions for ASD-associated differences in social behavior.”

Turning Rejection Into a Roadmap: Advice for the Next Generation of Mental Health Leaders
A Conversation with Tom Osborn, Founder of Africa’s Largest Mental Health Provider Shamiri Institute
Aaliyah Nadirah Madyun, program director at the Stavros Niarchos Foundation (SNF) Global Center for Child and Adolescent Mental Health at the Child Mind Institute, recently sat down with Tom Osborn, founder of the Shamiri Institute and an International Advisory Board member at the SNF Global Center. They discussed Osborn’s remarkable journey as a young entrepreneur.
At just 18, while studying at Harvard University, Osborn founded the Shamiri Institute, which has since grown into Africa’s largest youth mental health provider — now reaching over 100,000 young people annually and having trained and employed more than 3,000 providers. In this candid conversation, Osborn shares hard-won lessons on resilience, mentorship, and well-being. He offers advice to the SNF Global Center’s Youth Council members — many of whom are launching their own mental health initiatives in communities across Greece, Brazil, South Africa, and beyond.

AM: You founded Shamiri when you were just 18. Many members of our SNF Global Center Youth Councils are now launching their own mental health organizations. What advice would you give them?
TO: I think these past three to five years post-COVID have been quite good for mental health. There’s just more dialogue, more conversation. It’s maybe one of the best times to start working in mental health. There is a big space for young people to be leaders. On the other hand, it’s also very difficult.
AM: What kind of difficulties can young people expect to encounter?
TO: It’s very difficult for a few reasons. We normally start this work because we have a lot of passion, enthusiasm, and commitment to the cause. But that is not the day-to-day of being a social entrepreneur. It’s convincing people to partner with you, to fund you, etc., which is a completely different skill set to learn. And the second part is getting a level of comfort with failure. Because the reality is, on average, nine out of ten doors that you try to open will not open; especially when you are starting. For example, if you’re in Brazil and there are 100 other young people trying to start something, there is a finite pool of opportunities and resources. So, when you are starting, part of the initial process requires you to develop resilience and a growth mindset.
AM: Could you speak about the role mentorship has played in your journey, and how young entrepreneurs can leverage mentorship to navigate the challenges of building something from the ground up?
TO: Mentorship is really crucial. Finding folks — researchers, practitioners, or just folks in the community — who can help provide guidance as you build the skills you need to be an effective entrepreneur.
AM: How would you recommend young people go about finding a mentor? It seems like that ability, identifying and cultivating a mentoring relationship, might be a skill set in itself.
TO: In my experience, there are three pathways. In many countries we have what we call accelerators, which look for young people who literally have an idea and enthusiasm, and then take them through 10–16 weeks of bootcamp where they can learn the skills to develop their idea. So, that’s one pathway. The second pathway, which really worked for me but may sound intimidating, is direct outreach to folks who have done something similar. So, you can do some research. It doesn’t have to even be related to mental health. It can be education or some broader thing. But find someone who has built something that you admire. You will be surprised how many people are willing to support and pay it forward, because we all have benefited from the help of someone else. I created an Excel spreadsheet with a list of people who I looked up to, and I reached out to them on LinkedIn. Sometimes you can even find their email. Some people said “no”, but if you reach out to 10 or 20 people, some people will talk to you. And the third pathway is . . . increasingly we have a lot of resources like the SNF Global Center Youth Councils and international organizations that deal with mental health. You can join these organizations to expand your network.
AM: Could you share your story with us and tell us how you got started?
TO: I started when I was in University as part of a research project I was doing when I was studying psychology. I needed to do something for my thesis and in the process of doing that I applied to an accelerator. I also went to my professor and asked him, ‘Do you know anyone who could connect me with?’ In fact, he helped me write my first grant and gave me the opportunity to learn those entrepreneurial skills.
AM: Starting at such a young age, one can imagine that you must have encountered many challenges and setbacks. What were the key lessons you took away from that growth period?
TO: The reality of this work, and not to discourage people but to give a factual picture, is that there are more setbacks than there are wins. Part of the process is that you learn from the setbacks. I can give you an example of some of my own setbacks. In my first year of doing this, we tried to raise money. We applied for grants, sent out proposals, etc.; but we couldn’t raise any money. So, what I did after getting the rejection is I would email and ask, “Do you have any feedback for us about why we didn’t get the funding?” or “Can we jump on a call so you can explain what we can do better?” What I learned from that was the way I was communicating what we were doing made sense in my mind, but I wasn’t putting myself in the shoes of the person who was reviewing the proposal. I only have five to ten minutes of someone’s time. So, how can I really simplify my message? For example, my first proposal was, “Shamiri does task-shifting mental health interventions for adolescent depression, anxiety, etc.” If you are in the field, you maybe get it. But if you are somebody who is just reading grants on mental health education, you don’t really get it. Now we say, “Shamiri means thrive and we enable young people to thrive.” So that invites people to ask how we’re helping people to thrive.
AM: What is another setback that surprised you?
A second example of a failure is getting buy-in from the beneficiaries that we were trying to work with. I thought, “We have this great idea, we’ve done this research, and it works. We’re going to go to schools and they’re going to be like, ‘This is great! Come work with us.’ Teachers are going to want to work with us.” But actually, in our first three years we were trying to work with 25,000 students and we ended up working with only 1,000 students. We really struggled with getting people to sign up. The lesson from that was we were thinking more from the idea this was our product, rather than thinking, “What is the problem that I am trying to solve for this person?” To give a concrete example, there are three people we need to get buy-in from: young people in schools, teachers, and parents. Just having a great product does not mean that people are going to use it. You need to figure out what the problem is. How can I solve it? How do I communicate this to users?
AM: I can imagine that dealing with failures and setbacks is extremely hard, especially for a young person. What would you say to a young person who is currently experiencing this?
TO: Finding ways to stay grounded and healthy from a well-being perspective is really crucial. Identify what matters to you and connect with those things. And ideally if you can find a way to build a routine around that, it could help. Doing this work takes a big toll. If you don’t find ways to ground yourself and get the energy to continue with this, you may burn out.
AM: Do you have some final words for our Youth Council members and other young people reading this?
TO: Those closest to the problem are those closest to the solution. I am from Kenya, which is a really young country. The median age is 19 and 70 percent of the population is under 30. If we are to solve some of these pressing problems, including mental health, those solutions are going to have to come from young people.

Prevalence and Predictors of Self-Reported Adverse Experiences in Digital Meditation Training: 2 Randomized Controlled Trials
Background: Digital meditation-based interventions (MBIs) reach vast global audiences with millions of active users, yet concerns persist about the frequency and nature of adverse experiences (ie, AExs) occurring during meditation training. Some researchers have argued that AExs are substantially underdetected and reflect iatrogenic harm caused by meditation (ie, adverse effects [AEfs]). Others contend that these experiences largely reflect common stressors that would be experienced without meditation. These competing perspectives underscore the need for further research, particularly in the context of digital MBIs, the most widely used form of meditation training. Objective: This study examined the prevalence, predictors, and subjective evaluations of AExs during a digital MBI and tested whether reported experiences may be caused by meditation practice via comparisons between meditation-exposed and nonexposed participants. Methods: Data were drawn from 2 trials of the Healthy Minds Program. Exploratory study 1 (n=315) consisted of a sample of distressed US undergraduate students to estimate the prevalence of AExs and identify baseline predictors. Preregistered confirmatory study 2 (n=594) sampled distressed US adults from all 50 states to replicate findings from study 1 and to examine participants’ subjective evaluations of AExs. Study 2 additionally compared AEx rates between participants who did and did not complete guided meditations to assess whether AExs could be caused by meditation exposure. Study 3 (n=87) used qualitative methods to analyze study 1 participants’ responses to an open-ended question regarding their strategies for coping with AExs. Results: In studies 1 and 2, 27.9% (88/315) and 10.1% (40/396) of participants, respectively, reported at least one AEx during the study period, with 6.7% (21/315) and 3% (12/396) reporting functional impairment, largely aligning with previous research. Critically, in study 2, rates of AExs did not significantly differ between participants who did and did not complete guided meditations, suggesting that these experiences were not caused by meditation practice. Higher baseline depression, anxiety, loneliness, experiential avoidance, and perceived barriers to meditation predicted more frequent AExs. In studies 1 and 2, 89.8% (79/88) and 90% (36/40) of participants who reported AExs, respectively, indicated that they were glad to have learned to meditate. Qualitative analyses showed that participants used diverse coping strategies, often using skills learned through the Healthy Minds Program. Conclusions: AExs were relatively common but occurred at comparable rates among participants who did and did not meditate, challenging claims that such experiences were caused by meditation practice in distressed individuals. Although a small subset of participants reported some degree of functional impairment, most evaluated their AExs as tolerable and described their overall MBI experience as positive. Together, these findings highlight the importance of distinguishing AExs that likely reflect epiphenomena of preexisting distress or symptoms from iatrogenic harm attributable to MBIs. Trial Registration: Study 1: ClinicalTrials.gov NCT04741529; https://clinicaltrials.gov/study/NCT04741529; Study 2: ClinicalTrials.gov NCT06282523; https://clinicaltrials.gov/study/NCT06282523

Examining the Social and Mental Health Benefits of Virtual and In-Person Physical Activity Intervention Among Postsecondary Students: Quasi-Experimental Study
Tracking the longitudinal course of physiologic and mental health functioning among individuals in substance use disorder treatment
The Intersectionality of OCD and the Shame Surrounding Sexuality
By Mike Vatter
Obsessive-Compulsive Disorder (OCD) is often misunderstood as a condition involving excessive cleanliness, organization, or ritualistic behavior. In reality, OCD is a complex mental health disorder characterized by intrusive thoughts, unwanted images, fears, and compulsive behaviors intended to reduce anxiety. One of the least understood and most painful aspects of OCD occurs when intrusive thoughts intersect with sexuality, creating a profound sense of shame, confusion, and isolation.
Sexuality is already a deeply personal aspect of human identity. Many people grow up receiving messages, whether from family, religion, culture, or society, that certain thoughts, desires, or identities are inappropriate or unacceptable. When OCD enters this landscape, it can weaponize these fears and vulnerabilities. Intrusive thoughts often target what a person values most or fears most. As a result, individuals with OCD may experience unwanted sexual thoughts that feel completely inconsistent with their values, identity, or desires.
Someone with OCD may become trapped in relentless questioning: “What if I am attracted to someone I shouldn’t be attracted to?” “What if these thoughts mean something about who I really am?” “What if I am secretly a bad person?” These questions are not driven by genuine desire but by overwhelming anxiety and uncertainty. Nevertheless, the individual often feels compelled to seek reassurance, analyze their reactions, or avoid situations that trigger distress.
The shame surrounding sexuality intensifies this struggle. Society frequently treats sexual thoughts as reflections of character rather than recognizing that thoughts can occur without intent, desire, or meaning. For people with OCD, this misunderstanding can be devastating. Many become terrified that simply having an intrusive thought makes them immoral, dangerous, or fundamentally flawed. As a result, they often suffer in silence, afraid that disclosing their thoughts will lead to judgment or rejection.
The intersection of OCD and sexuality can affect people of all sexual orientations and gender identities. Some individuals experience obsessions centered on questioning their sexual orientation, regardless of whether they identify as heterosexual, gay, bisexual, or otherwise. Others experience intrusive thoughts involving taboo or unwanted sexual scenarios. In each case, the distress comes not from the thoughts themselves but from the meaning the individual fears those thoughts represent.
This experience is particularly challenging because shame thrives in secrecy. The more a person attempts to suppress, analyze, or eliminate intrusive thoughts, the stronger and more persistent those thoughts often become. OCD feeds on certainty-seeking, convincing individuals that if they can just think hard enough or find enough reassurance, they will finally feel safe. Unfortunately, the cycle rarely ends that way.
Recovery begins when individuals learn to separate intrusive thoughts from identity and intention. Evidence-based treatments such as Exposure and Response Prevention (ERP) help people tolerate uncertainty and reduce compulsive responses. Through treatment, many discover that thoughts are not actions, urges are not intentions, and anxiety is not evidence. They learn that having an intrusive thought says far less about their character than the courage it takes to face that thought without engaging in compulsions.
Understanding the intersectionality of OCD and sexual shame requires compassion, education, and nuance. It demands that we challenge cultural assumptions about thoughts and morality while recognizing the unique suffering OCD can create. When people understand that intrusive thoughts are a symptom of a disorder rather than a reflection of character, shame begins to lose its power.
Ultimately, healing occurs not when every intrusive thought disappears, but when individuals no longer measure their worth by the thoughts that enter their minds. By replacing shame with understanding and fear with self-compassion, people living with OCD can reclaim both their mental health and their sense of identity.
