This study used mass cytometry to create a scientific ‘map’ of the immune system. Then, scientists compared the immune system maps of people with Down syndrome to those without and found that, on average, people with Down syndrome have dysregulation in every detected branch of their immune system…..

This project took a deep dive into the T cell biology of people with Down syndrome. T cells are an important cell in the immune system. There are numerous types and subtypes of T cells, each with specific functions in the immune response. For example, “cytotoxic T cells” kill dangerous cells infected by virus or from tumors…..
