    Bio X Cell monoclonal antibodies against mouse lag 3
    a , UMAP plots displaying distribution of Ltb, Areg and Lag3 transcripts across different cell types in mouse skin. Each dot is one cell, color-coded based on transcript expression levels. b, Schematic of the Ltb-CreER x R26-tdT mouse line. c, Left: Representative whole mount immunofluorescence showing that double positive (tdT + and TCRγδ + ) LTB-expressing DETCs reside primarily within the uHF compartment as do other LTB-expressing lymphocytes (tdT + and TCRγδ neg ). Epithelial SCs are marked by K14. Scale bar 30μm. Right: quantifications of (left) the probability of finding LTB + DETCs (tdT + and TCRγδ + ) in uHF vs IFE and (right) probability of finding any LTB + cell (tdT + ) in the uHF region vs IFE. Each circle represents data from one mouse (3-8 fields of view). d-e , Representative FACS plots and quantifications showing that most DETCs expressing AREG (d) <t>and</t> <t>LAG-3</t> (e) are uLIPSTIC neg (IFE-DETC) and not uLIPSTIC + (uHF-DETC). MFI, mean fluorescence intensity. f, Percentage of LTB-tdT + , AREG + or LAG-3 + DETC out of total DETC as quantified by FACS of the skins of mice at the indicated postnatal time points. Each point represents the mean with SEM of 2-7 mice. g, Percentage of AREG + DETC in the embryonic thymus of E17-18 pups and from the back skin of adult second telogen mice as quantified by FACS. h, Quantifications of total skin intraepithelial Ltb transcripts determined by qPCR, and AREG + or LAG-3 + DETC determined by FACS when mice are kept in specific pathogen free (SPF) or germ-free (GF) facility. i, Schematic summarizing the compartmentalization of the two DETC niche programs in steady state. Data are representative of two-four (panel h), two (panel e), three (panel c, d, g) or three-seven (panel f) independent experiments and, unless indicated, each circle represents one mouse. Data in c, d, g and h are analysed by unpaired two-tailed Student’s t- test. p- values are indicated in each figure and data are represented as mean with SEM.

Each point represents the mean with SEM of 2-7 mice. g, Percentage of AREG + DETC in the embryonic thymus of E17-18 pups and from the back skin of adult second telogen mice as quantified by FACS. h, Quantifications of total skin intraepithelial Ltb transcripts determined by qPCR, and AREG + or LAG-3 + DETC determined by FACS when mice are kept in specific pathogen free (SPF) or germ-free (GF) facility. i, Schematic summarizing the compartmentalization of the two DETC niche programs in steady state. Data are representative of two-four (panel h), two (panel e), three (panel c, d, g) or three-seven (panel f) independent experiments and, unless indicated, each circle represents one mouse. Data in c, d, g and h are analysed by unpaired two-tailed Student’s t- test. p- values are indicated in each figure and data are represented as mean with SEM.

    a , Percentage of LAG-3 + cells gated on DETC, ILC or TCRαβ + T cells in wild type back skin as determined by FACS. b, Left: strategy to block LAG-3 in vivo . Right: quantifications reveal that DETCs but not TCRαβ + T cells increase in numbers in the skin when anti-LAG-3 antibodies are delivered intraperitoneally to mice. c, Left: representative max projections of whole mount immunofluorescence of IFE and uHF compartments showing that the increase in DETC (in yellow) resulting from anti-LAG-3 blocking antibodies occurs largely in the IFE-SC and not the uHF-SC niche. Scale bar 50μm. * denote autofluorescence. d, Normalized concentration of AREG determined by ELISA shows elevated AREG in the intraepithelial tissue, consistent with the elevation in DETCs caused by LAG-3 inhibition. e, Normalized percentage of EdU + SCs determined by FACS after a 3-hour pulse in mice injected with either PBS or anti-LAG-3 blocking antibodies. f, Top: strategy to deliver recombinant AREG (rAREG) systemically in vivo by osmotic pump implantation; bottom: concentration of AREG determined by ELISA in the intraepithelial tissue of mice implanted with pumps containing either rAREG or PBS as a control. g, Percentage of EdU + SCs determined by FACS after a 4-hour pulse in mice implanted with pumps containing either rAREG or PBS as a control. Data are representative of two (panel f), three (panel c, d, g), five (panel a, e) or seven (panel b) independent experiments and each circle represents one mouse. Data in b, c, d, e, f and g are analyzed by unpaired two-tailed Student’s t- test. Data in panel a are analyzed by ordinary one-way ANOVA with Tukey’s multiple comparison post-test. p- values are indicated in each figure and data are represented as mean with SEM.
