Figure Lengend Snippet: RFA induces TIRAP/MyD88 but not TRAM/TRIF association. (A–D) . Mice was subjected to RFA or Sham treatment or ID injection of 5 µg LPS. Skin was collected 6 h later and subjected to cryo-sectioning and PLA analysis of close association of MyD88 and TIRAP (A, B) as well as TRIF and TRAM (C, D) . Representative PLA images were shown in (A, C) and quantitative results were shown in (B, D) . Arrows point to PLA signals. E. Skin sections in RFA groups in the above studies were also stained with fluorescence-conjugated anti-MHC II antibodies. Z-stack pictures were captured and used to create 3D images. Representative 3D pictures showing the overlapping of RFA-induced TIRAP/MyD88 PLA signals with MHC II. Arrows point to overlapping signals (yellow). (F) Pie chart of PLA signals overlapped with MHC II (blue). Scale: 100 µm in (A, C, E) . One-way ANOVA with Newman-Keuls multiple comparison test was used to compare differences between groups in (B, D) . n=14–20 in (B) and n=6–8 in (D) . Over 50 PLA signals were explored by investigators in (F) . *, p<0.05; **, p<0.01; ***, p<0.001. Data are representative of three independent experiments with similar results.

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 . Data are representative of two independent experiments with similar results.

doi: 10.3390/biom14111441

Figure Lengend Snippet: 3α,5α-THP inhibits TIRAP binding to MyD88 in P rat male ( A ) and female ( B ) hippocampi. MyD88 immunoprecipitation of various components of the myddosome complex was conducted in male and female, vehicle- (45% w / v 2-hydroxypropyl-β-cyclodextrin; 30 min) and 3α,5α-THP-treated (15 mg/kg; 30 min) P rats ( A , B ).

Immunoblots and densiometric measurements of extracted hippocampal TIRAP ( G ) and MyD88 ( H ) in vehicle- and 3α,5α-THP-treated animals. Western blot original images are in the . *** p < 0.005, **** p < 0.001, ns: no significant difference.

doi: 10.1111/cns.14681

Figure Lengend Snippet: TLR (toll‐like receptor) signaling pathway is upregulated in the inflammation induced by Prx2 (peroxiredoxin 2). (A) KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis of DEGs (differentially expressed genes) in the ipsilateral basal ganglia at 24 h after saline or Prx2 injection (10 μL); n = 5 for saline and n = 7 for Prx2. Dot color represents Q‐value from the least significant (green) to the most significant (red); dot size represents gene number, the number of significant DEGs in the KEGG pathway; rich factor represents the fraction of significant DEGs among all genes in the KEGG pathway. (B) FPKM (Mean fragments per kilobase of transcript per million mapped reads) values of TLR2, TLR4, Myd88 (myeloid differentiation primary response protein 88) in the ipsilateral basal ganglia at 24 h after saline or Prx2 injection. Values are mean ± SD; n = 5 for saline and n = 7 for Prx2; # p < 0.01 versus saline group. (C) TLR4 immunofluorescence at the ipsilateral basal ganglia 24 h after saline or Prx2 injection.
