Figure Lengend Snippet: HSP70 contributes to RFA-enhanced antigen uptake in skin and draining LNs. WT and HSP70 KO were subjected to RFA or Sham treatment followed by ID injection of 2 µg AF647-OVA into RF or Sham-treated skin. Skin and draining LNs were dissected 20 h later followed by single-cell suspension preparation, immunostaining, and flow cytometry analysis. Gating strategies were shown in Supplementary Figures S1B, C . (A) Percentages of AF647-OVA+ cells in skin DCs (CD11c+ MHC II+) in WT and HSP70 KO mice.

Figures 5A, B were analyzed for expression of surface co-stimulatory molecules (CD40, CD80, and CD86) in CD11c+ DCs of WT and HSP70 KO mice. MFI of CD40, CD80, and CD86 was compared between groups. (B–D) . The same LN samples as in
Figures 5C, D were analyzed for expression of surface co-stimulatory molecules (CD40, CD80, and CD86) in cDC (B) , migDC (C) , and pDC (D) of WT and HSP70 KO mice. MFI of CD40, CD80, and CD86 was compared between groups. (E) BMDCs were incubated with AF647-OVA alone (control) or in the presence of HSc70 or HSP70-rich elutes or LPS. Cells were analyzed for their surface expression of CD40, CD80, and CD86 24 h later. MFI of CD40, CD80, and CD86 was compared between groups. Two-way ANOVA with Newman-Keuls’s multiple comparison test was used to compare differences between groups in A-D. One-way ANOVA with Tukey’s multiple comparison test was used to compare differences between groups in (E) n=6–8 in A-D. n=6 in (E) *, p<0.05; **, p<0.01; ***, p<0.001.

Figure Lengend Snippet: HSP70 suppresses RFA-induced TLR4/IRAK/NFκB signaling. (A, B) WT and HSP70 KO mice were subjected to RFA or Sham treatment or ID injection of LPS or PBS. Skin was collected 6 h later in (A, B) IP and IB were conducted to evaluate TLR4/TIRAP binding (A) and IRAK4/IRAK1 binding in (B, C) . WT, HSP70 KO, MyD88 KO, TLR2 KO, and TLR4 KO mice were subjected to RFA or Sham treatment or ID injection of LPS. Skin was collected 2 h later. Cytosol and nuclear fractions were separated and nuclear fraction was analyzed by WB analysis to detect phosphorylated p65 using Lamin b1 as a loading control. (D) Skin IL-6 levels 6 h after RFA, Sham, or LPS treatment of lateral back skin of WT, HSP70 KO, TLR2 KO, TLR4 KO, and MyD88 KO mice. Two-way ANOVA with Fisher’s LSD test was used to compare differences between groups. n=4-6. *, p<0.05; **, p<0.01; ***, p<0.001. Original membrane pictures were shown in Supplementary Figure S9 .
