Here the authors develop a consensus, cross-reactive allergen, use mRNA-lipid nanoparticle immunization to induce specific, neutralizing IgG responses, but find no therapeutic effects in mouse allergy models, hinting the need for further optimization prior to translation.

Exhaustion is a functional state that hampers anti-cancer and antiviral CD8 T cell activity, and is preceded by a stem-like state, maintained by the transcription factor TCF1. Here authors develop mouse models that allow a precise understanding of the developmental trajectory between the stem-cell-like and exhausted states of CD8 T cells and find that while constitutive overexpression of TCF1 expands the stem-like T cell pool, TCF1 expression specifically in already exhausted cells is unable to promote dedifferentiation.
