A conversation with Philip Goulder about the recent article ‘Sustained aviremia despite anti-retroviral therapy non-adherence in male children after in utero HIV transmission’. In this episode of To Immunity and Beyond, we discuss a prospective study of 284 children from KwaZulu-Natal, South Africa, who were treated very early with antiretroviral therapy (ART) after mother-to-child transmission of HIV. Unexpectedly, female fetuses were more susceptible to in utero transmission, but of 5 children identified who maintained undetectable levels of HIV despite unscheduled ART interruption, all were males. Distinct viruses were transmitted to males and females - females but not males being susceptible to type I interferon-resistant, low fitness viruses. These findings indicate the central role that early life innate immune sex differences play in HIV cure/remission in children.

Research with Human Tissue Samples on the International Space Station, with Dr Ghada Alsaleh
Research on human cells in space may uncover the hidden mechanisms behind ageing. Exciting developments are underway at the Space Innovation Lab at the University of Oxford! The launch of human tissue samples to the International Space Station marks a bold and forward-looking step in scientific discovery—one aimed at unravelling the mysteries of ageing. This pioneering research holds tremendous potential for unlocking transformative insights into musculoskeletal health and regenerative medicine, paving the way for future breakthroughs that could benefit millions on Earth.
