Tertiary lymphoid tissues in aged injured mouse kidney. Tertiary lymphoid tissues are mainly composed of T cells and B cells, some of which are proliferating. p75NTR-positive fibroblasts extend their projections and form a structural backbone within TLTs. a green: CD3ε, red: B220. b green: p75NTR, red: Ki67.
