    Article Snippet: Human CK2β is an 24.9 kDa protein with 215 amino acids encoded by the gene CSNK2B.. It is usually considered as an integral part of human protein kinase CK2, with a CK2α2β2 composition.. The CK2β amino acid sequence is highly conserved among species,1– 3 however, no other homologous protein has been described so far for CK2β, except the stellate protein from Drosophila melanogaster.4 It is known to interact with CK2α as well, but of unknown function.5 In human, single point mutations within CSNK2B leads to developmental disorders and reduced brain function, such as in the PoirierBienvenu syndrome.6,7 In mice, a complete knockout of CSNK2B results Received: 20 September 2022 | Revised: 19 December 2022 | Accepted: 9 January 2023 DOI: 10.1096/fba.2022-00098

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. (B) Representative histogram of AF647-OVA levels in skin DCs of different groups in WT and HSP70 KO mice. (C) Representative dot plots of AF647-OVA+ migDCs of different groups in WT and HSP70 KO mice. (D) Percentage of AF647-OVA+ cells in migDC (D) , cDC (E) , and pDC (F) in WT and HSP70 KO mice. Two-way ANOVA with Fisher’s LSD test was used to compare differences between groups. n=8. *, p<0.05; **, p<0.01; ***, p<0.001. Data are representative of two independent experiments with similar results.

    RFA-induced HSP70 lacks the ability to induce DC maturation. (A) The same skin cell samples in <xref ref-type= 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.

    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.
