Single session of exercise rapidly alleviates depressive mood: Hong Kong Polytechnic University study reveals neural mechanism and preventative potential

  Prof. Sonata YAU, Member of the Mental Health Research Centre (MHRC) and Associate Professor in the Department of Rehabilitation Sciences at The Hong Kong Polytechnic University, has uncovered the neural mechanism behind the rapid antidepressant effect of a single bout of physical exercise. Her team found that just one 30-minute treadmill running at intermediate intensity could rapidly elevate mood in university student participants. Mechanistic evidence from animal models revealed that this effect is mediated by the activation of specific glutamatergic neurons in the anterior cingulate cortex (ACC)—a key brain region for emotion regulation—via the hormone adiponectin, which triggers nuclear translocation of the adaptor protein APPL1. This cascade enhances synaptic protein expression and spine formation through epigenetic regulation, leading to immediate relief of depressive symptoms. These findings highlight the powerful potential of physical exercise as a practical and accessible intervention for managing mood disturbances in young adults. Crucially, the research suggests that prompt physical exercise can help prevent the worsening of depressive mood, serving as an effective preventative measure against depression and supporting mental well-being in this population. The study provides robust scientific evidence for the rapid antidepressant effects of physical exercise, paving the way for immediate rehabilitation strategies for depressive mood. This work has been recently published in Molecular Psychiatry, a leading journal in Psychiatry and Neuroscience Research.

MHRC receives donation from the Lux Academy Hong Kong Investment Limited to develop occupational therapy service for mental hospitals in mainland China

Prof. Hector TSANG, Chair Professor of Rehabilitation Sciences and Co-Founder of the Mental Health Research Centre (MHRC) at PolyU, has received a generous donation from Lux Academy Hong Kong Investment Limited for a four-year project titled “A Translational Research on the Development of Evidence-based Occupational Therapy Service in a Mental Hospital of the Mainland”. Long-term rehabilitation and community-based support play an important role in helping patients with mental illnesses to regain functional skills, autonomy and confidence, and facilitating their recovery and social integration. The current mental health system in mainland China predominantly focuses on medication and hospitalisation as treatment method. However, this strategy has not been able to effectively reduce the relapse in patients in the long run, and heavily relies on caregiver support, thus putting burden on families and communities. In view of Mainland’s need for a new mental health treatment model, the PolyU research team will design evidence-based occupational therapy services for persons with mental illnesses, and collaborate with mental hospitals in mainland China in implementing the novel programme. The project would help drive a shift of focus in Mainland’s mental health care from hospitalisation to community-based support, and from cure to recovery.  

Prof. Nathanael JIN Ling’s study reveals public health risks of drug-resistant Candida in cities

Prof. Nathanael JIN Ling, Member of the Research Institute for Future Food (RiFood), the Research Institute for Sustainable Urban Development (RISUD) and the Mental Health Research Centre (MHRC), and Assistant Professor in the Department of Civil and Environmental Engineering and the Department of Health Technology and Informatics, has recently published a pioneering research in Environmental Science & Technology Letters, shedding light on the public health risks posed by airborne Candida species in densely populated urban areas. The key findings of the study are as follows: • Drug-Resistant Candida in Urban Air: The study detected viable, drug-resistant strains of Candida parapsilosis, Candida albicans, and Candida tropicalis in city air samples—strains that were notably absent in coastal environments. • Genetic Similarity to Clinical Strains: Airborne isolates exhibited a high degree of genetic similarity to those found in clinical settings, suggesting that community-acquired infections could occur through inhalation or skin contact. • Multidrug Resistance: Of particular concern was the discovery of multidrug resistance in C. parapsilosis, raising questions about the role of urban pollution and climate change in driving antifungal resistance. Candida species are classified as WHO fungal priority pathogens due to their severe health impacts.  Prof. Jin’s research highlights the urgent need to recognise urban air as a significant medium for the spread of antifungal-resistant strains.  Looking ahead, his research team plans to expand their work to larger, multi-site studies to better understand fungal transmission pathways, investigate urban reservoirs of drug-resistant fungi and strengthen One Health approach to combat the global threat of fungal resistance.

PolyU research reveals neurocognitive correlates of testosterone in young men that shape generosity and self-worth

A research team led by Prof. WU Yin, Associate Professor of the PolyU Department of Applied Social Sciences and Member of the Mental Health Research Centre (MHRC), has conducted interdisciplinary research to uncover the neurocognitive correlates of testosterone in the brain function of young men, and their impact on social behaviour.  The findings provide valuable insights into potential applications of testosterone therapy in clinical and mental healthcare. Their first study focused on the impact of testosterone on socio-economic behaviour.  The researchers combined pharmacological manipulation and functional magnetic resonance imaging (fMRI) to discover how testosterone influences generosity and the underlying neural mechanisms.  Findings revealed that exogenous testosterone administration reduced generosity, particularly when interacting with more distant others.  Additionally, the fMRI results showed that higher testosterone levels are linked to reduced neural activity in the temporoparietal junction (TPJ), an upper brain region associated with social cognition.  The team suggested that testosterone may reduce concern for others’ welfare at the neural level by dampening activity in the TPJ, highlighting a correlation between increased testosterone levels, and selfishness and reduced empathy in economic decision-making. In another related study, the team explored the link between state self-esteem (SSE), a momentary sense of self-worth and perceived social status, and testosterone levels.  The team found that testosterone administration can boost SSE updating and alleviate aberrant behaviours linked to psychiatric conditions such as anxiety, depression, eating disorders and schizophrenia.  The research indicated that a single dose of testosterone can positively influence SSE, particularly in positive social environments.  It is suggested that future clinical practice consider combining exogenous testosterone with behavioural interventions that foster supportive environments and social feedback to enhance SSE as a potential pre-clinical treatment for relevant aberrant behaviours and clinical symptoms. The two studies have been published in the Proceedings of the National Academy of Sciencesand the Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, respectively.  In recognition of his excellent research, Prof. Wu has been honoured with the Second-class Award under the 9th Higher Education Outstanding Scientific Research Output Awards (Humanities and Social Sciences) by the Ministry of Education of China.
