- Abstract
- Here, we identify cells within human adult secondary lymphoid tissues that are comparable in phenotype and location to the lymphoid tissue inducer (LTi) cells that persist in the adult mouse. Identified as CD117(+)CD3(-)CD56(-) cells, like murine LTi cells, they lack expression of many common lineage markers and express CD127, OX40L and TRANCE. These cells were detected at the interface between the B- and T- zones, as well as at the subcapsular sinus in LNs, the location where LTi cells reside in murine spleen and LNs. Furthermore, like murine LTi cells, these cells expressed high levels of IL-22 and upregulated IL-22 expression upon IL-23 stimulation. Importantly, these cells were not an NK cell subset since they showed no expression of IFN-gamma and perforin. Interestingly, a subset of the CD117(+)CD3(-)CD56(-)OX40L(+) population expressed NKp46, again similar to recent findings in mice. Finally, these cells supported memory CD4(+) T-cell survival in an OX40L-dependent manner. Combined, these data indicate that the CD117(+)CD3(-)CD56(-)OX40L(+) cells in human secondary lymphoid tissues are comparable in phenotype, location and function to the LTi cells that persist within adult murine secondary lymphoid tissues.
