Transcription factors define tissue T cells: The immune system fights microbial invaders by maintaining multiple lines of defense. For instance, specialized memory T cells [resident memory T cells (T rms )] colonize portals of pathogen entry, such as the skin, lung, and gut, to quickly halt reinfections. Mackay et al. now report that in mice, T rms as well as other tissue-dwelling lymphocyte populations such as natural killer cells share a common transcriptional program driven by the related transcription factors Hobit and Blimp1. Tissue residency and retention of lymphocytes require expression of Hobit and Blimp1, which, among other functions, suppress genes that promote tissue exit. Science , this issue p. 459

Tissue-resident memory T cells provide local immune protection in barrier tissues, such as skin and mucosa. However, the molecular mechanisms controlling effector T cell retention and subsequent memory formation in those locations are not fully understood. In this study, we analyzed the role of CD69, an early leukocyte activation marker, in regulating effector T cell egress from peripheral tissues. We provide evidence that CD69 surface expression by skin-infiltrating CD8 T cells can be regulated at multiple levels, including local Ag stimulation and signaling through type I IFNRs, and it coincides with the transcriptional downregulation of the sphingosine-1-phosphate receptor S1P1. Importantly, we demonstrate that expression of CD69, by interfering with sphingosine-1-phosphate receptor function, is a critical determinant of prolonged T cell retention and local memory formation. Our results define an important step in the generation of long-lived adaptive immune memory at body surfaces.

Significance: Tissue-resident memory T cells (T RM ) form in the skin where they are retained and can protect against subsequent infection. Using a combination of intravital imaging and mathematical modeling of skin T RM that form after cutaneous herpes simplex virus 1 infection, we reveal that these memory T cells persist at the site of infection for the life of a mouse owing to slow random migration. We also report that T RM compete with dendritic epidermal γδ T cells in skin for local survival signals, suggesting that T cells compete for space within an epidermal niche.
