A study led by the Hospital del Mar Research Institute has established the importance of immunoglobulin A, an antibody that is part of the immune system, in generating a response to pneumonia vaccines.

Researchers have found that the absence of this antibody leads to an overgrowth of gut microbiota, triggering an excessive and sustained immune system response, which ultimately becomes exhausted and fails to respond effectively to vaccines.

The study, published in Science Advances, opens the door to exploring the possibility of early immunoglobulin therapy administration to prevent this process and reduce the risk of potentially dangerous infections, even in at-risk individuals without a diagnosed immunodeficiency

Professor JianQiao Zhou’s team at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, has developed a latent diffusion model named CoLDiT. This model generates high-quality breast ultrasound images across different BI-RADS categories to overcome medical data sharing barriers. The study, titled “Synthetic Breast Ultrasound Images: A Study to Overcome Medical Data Sharing Barriers,” was published in the journal Research (DOI: 10.34133/research.0532).

Do you have lots of close friends – and work hard to keep it that way? If you’ve answered “yes”, you are probably nostalgic.
