gut mesenchymal lymphoid tissue organizer cell
gut mesenchymal lymphoid tissue organizer cell
A mesenchymal stromal cell found in the gut during development, and interacts with lymphoid tissue inducer (LTi) cells to drive secondary lymphoid organ formation (Prados et al., 2021). It expresses LTβR, PDGFRα, and VCAM, and upon activation secretes chemokines(e.g. CXCL13) and cytokines to organise lymphoid tissue architecture and recruit immune cells in both mice and humans (Denton el al., 2019; Elmentaite et al., 2021). As a multipotent progenitor, an mLTo cell differentiates into adult stromal subsets, including fibroblastic reticular cells (FRCs) (Prados et al., 2021), and its descendants persist in the adult gut-associated lymphoid tissues to maintain immune homeostasis(Denton el al., 2019; Lütge et al., 2021).
