In a society increasingly shaped by scientific progress, it is crucial that everyone, regardless of their background or ability, feels empowered to participate in these conversations. However, this is not usually the case for blind or low-vision communities who are often excluded, in part due to scientific outreach events being historically limited to visual imagery. To break down such barriers, we organized a multisensory exhibition as part of the Cambridge Festival 2024. The initiative was inspired by Monash Sensory Science, a targeted outreach program designed to engage individuals who are blind, have low vision or diverse needs. Our aim was to use novel, tactile and informative models to explore the role of the immune system in the central nervous system health and disease, focusing on two inflammation models: traumatic brain injury and multiple sclerosis. In Sensory Science, we fostered the involvement of the blind and low-vision community through tactile scientific posters, resin and plaster brain models, and interactive experiences involving heat, sound, tactile poetry and photography. The Sensory Science exhibition held during March 2024 not only promoted equality but also reminded us that true innovation lies in the collective efforts of a diverse and inclusive community.</p>","PeriodicalId":179,"journal":{"name":"Immunology & Cell Biology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to delineate the causal relationships among immune cells, PCOS and potential blood metabolites through Mendelian randomization (MR). A two-sample MR analysis was conducted using inverse variance weighting as the primary method to determine the causation between immune cells and PCOS risk. This was supplemented by a two-step MR analysis to assess the mediating role of blood metabolites between immune cells and PCOS. In addition, a series of sensitivity analysis methods were employed to test the robustness of the results. We also performed a reverse MR to evaluate the possibility of reverse causal relationships. Our findings identified 22 immune cell phenotypes causally linked to PCOS, with 12 acting as risk factors and 10 as protective factors for PCOS. Furthermore, 45 blood metabolites or ratios were causally related to PCOS. Mediation analysis revealed that X-25519 levels mediated 9.2% of the causal relationship between the absolute count of CD28^-CD25⁺⁺ CD8^br and PCOS. In addition, N-acetylglucosamine/n-acetylgalactosamine levels and adenosine 5'-monophosphate levels mediated 6.7% and -11.1%, respectively, in the causation between naive DN(CD4^- CD8^-) %T cell and PCOS. The aspartate-to-citrate ratio mediated 8.6% of the causal relationship between CD20^- CD38^- %B cells and PCOS. Finally, reverse MR studies did not identify any reverse causation between the 22 immune cell phenotypes and PCOS. This study elucidates the causal links between immune cells and PCOS, highlighting the potential roles of four blood metabolites in mediating the interaction between immune cells and PCOS, thus providing new targets for research and therapeutic interventions.</p>","PeriodicalId":179,"journal":{"name":"Immunology & Cell Biology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But science isn't just about discovery-it's also about impact. And somewhere along the way, I realized that my passion extended beyond experiments and data-I wanted to help shape the research landscape itself. That realisation led me to my current role as a Research Advisor for the Ovarian Cancer Research Foundation (OCRF), where I now work to bridge the gap between research and funding, ensuring that the needs of those with a lived experience of ovarian cancer align with the research. The transition from academic research to the not-for-profit sector wasn't without its challenges. I had to navigate uncertainty, redefine my professional identity and learn to recognise the value of my transferable skills-critical thinking, science communication and strategic planning. This journey has reinforced what I haven't always realized: science isn't confined to the laboratory. It's in the conversations we have, the policies we influence and the way we shape the future of research.

To determine the role of mouse MGL1 in colitis-associated colon cancer (CAC), azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced tumor development was compared between Mgl1 knockout (Mgl1^-/-) mice and their wild-type (WT) littermates. At 75 days post-CAC induction, colon tumor tissue contained more highly glycosylated proteins, representing potential ligands for the mMGL1 receptor, than did healthy colon tissue. The Mgl1^-/- CAC mice scored lower in disease activity indices and had fewer colonic tumors. In addition, the colonic crypt architecture was less damaged, and mucin production was more significant than in the WT CAC mice. Furthermore, Mgl1^-/- CAC mice displayed higher percentages of CD4⁺ and CD8⁺ T cells in the peripheral blood, and colonic lamina propria; and lower percentages of myeloid-derived suppressor cells (MDSCs). Additionally, less macrophage (Mφ) and natural killer (NK) cell infiltration and lower levels of iNOS and arginase were found in the tumor microenvironment of Mgl1^-/- CAC mice compared with WT mice.

Making STEM education more accessible is crucial for blind, low-vision and diverse-needs (BLVDN) communities, where grasping complex biomedical concepts can be challenging. Such accessibility promotes equal opportunities and encourages innovation through diverse perspectives. This paper examines the Sensory Science Cambridge exhibition, held at the Cambridge Festival in March 2024, aiming to enhance the accessibility of biomedical concepts for BLVDN communities, inspired by Monash Sensory Science in Australia. The exhibition included several tactile exhibits, including one designed to educate on the nature of human papillomavirus (HPV) infections and their link to cervical cancer through a diorama art piece. We were guided by the question: How can tactile and sensory materials convey HPV infection and its progression to cervical cancer? To achieve this, we developed a tactile diorama for independent navigation, featuring braille keys, explanatory panels and verbal descriptions. The diorama was created through collaboration between scientists and artists, and its effectiveness was evaluated through participant feedback and observational studies during the exhibition. The diorama significantly improved the participants’ understanding of HPV and cervical cancer, providing new or building on existing knowledge. The success of this exhibition project provides a model for using tactile and sensory materials in biomedical education. It highlights the potential of sensory science approaches in making STEM education more accessible and underscores the importance of interdisciplinary collaboration in creating accessible, scientifically rigorous communication tools, offering insights for future inclusive science outreach.</p>","PeriodicalId":179,"journal":{"name":"Immunology & Cell Biology","volume":"103 4","pages":"341-349"},"PeriodicalIF":3.2,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/imcb.70010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
