abstract = {The thymus is responsible for generating a diverse yet
self-tolerant pool of T cells1. Although the thymic medulla
consists mostly of developing and mature AIRE+ epithelial
cells, recent evidence has suggested that there is far
greater heterogeneity among medullary thymic epithelial
cells than was previously thought2. Here we describe in
detail an epithelial subset that is remarkably similar to
peripheral tuft cells that are found at mucosal barriers3.
Similar to the periphery, thymic tuft cells express the
canonical taste transduction pathway and IL-25. However,
they are unique in their spatial association with cornified
aggregates, ability to present antigens and expression of a
broad diversity of taste receptors. Some thymic tuft cells
pass through an Aire-expressing stage and depend on a known
AIRE-binding partner, HIPK2, for their development. Notably,
the taste chemosensory protein TRPM5 is required for their
thymic function through which they support the development
and polarization of thymic invariant natural killer T cells
and act to establish a medullary microenvironment that is
enriched in the type 2 cytokine, IL-4. These findings
indicate that there is a compartmentalized medullary
environment in which differentiation of a minor and highly
specialized epithelial subset has a non-redundant role in
shaping thymic function.},
