Extended Data Fig. 4. IL-17 levels in adult and aged mouse and human skin.

Extended Data Fig. 4

a, Dot plot showing percentage of cells expressing and average expression of IL-17 receptors Il17ra and Il17rc, and ligands Il17a and Il17f in all dermal cell types. Black boxes enclose lymphoid subtypes that show differential expression of Il17a and Il17f upon aging. b, Fluorescent in situ hybridization (FISH) for IL17A (n = 4 individual donors for adult and n = 3 individual donors for aged) and IL17F (n = 4 individual donors for each age) in adult and aged human skin (top panel). Bar = 50μm. White arrows point to positive cells. Insets with higher magnification focusing on the dermis in the bottom panel, bar = 10μm. Plot shows quantification in percentage of positive cells. Brightness and contrast were adjusted only for visualization purposes. Quantifications were done in raw images.
