T cells have a central role in adaptive immune responses. However, no accurate assays currently exist that link measurements of ex vivo or in vitro function to effective in vivo T cell responses. Diagnostic detection of T cell function in infectious and immune-mediated diseases also lags in vitro assessments of antibody function. An improved understanding of T cell responses will help researchers and clinicians better predict immune outcomes in response to vaccines, pathogenic infections or immune-mediated diseases. To address these issues, the National Institute of Allergy and Infectious Diseases (NIAID) convened the ‘T Cell Technologies: Assays, Innovations, Challenges, and Opportunities Workshop’ on 15–16 June 2022. The goals of the workshop were to explore assays and technologic advances that could improve understanding of T cell activation and function in different immune conditions, tissues and infections, and to identify methodologies that best provide an accurate measure of T cell biological relevance.
