Article Title: KANK4 Regulates CXCL16 Glycosylation Through TMEM260 to Modulate Microglial Activation in Sepsis-associated Encephalopathy
Journal: Inflammation
doi: 10.1007/s10753-026-02481-y
Figure Legend Snippet: KANK4 regulated CXCL16 glycosylation and microglial activation via TMEM260. Microglia were isolated from the hippocampus of mice in Sham, SAE, SAE + AAV-NC, and SAE + AAV-KANK4 groups, followed by the following analyses: (A) IHC was performed to detect CXCL16 protein expression. Microglia were isolated from the Sham and SAE groups for the following assays: (B) Western blot analysis was conducted to assess CXCL16 glycosylation levels ( n = 3). (C) Co-IP was carried out to examine the interaction between TMEM260 and CXCL16. BV2 microglial cells were treated with LPS to establish a cell model. Control and LPS groups were subjected to the following analyses: (D) Western blot analysis was applied to detect CXCL16 expression using both anti-CXCL16 and anti-His-CXCL16 antibodies ( n = 3). (E) Co-IP was conducted to validate the interaction between TMEM260 and CXCL16. (F) Western blot was used to assess O-mannosylation of CXCL16 protein in LPS-treated microglia ( n = 3). (G) Effect of CXCL16 glycosylation site mutations on its glycosylation level. Wild-type (WT) and site-specific mutant (S137A, S117A, S139A) CXCL16 plasmids were transfected into microglia. CXCL16 glycosylation was assessed by Western blot ( n = 3). (H) Impact of CXCL16 glycosylation site mutation (S117A) on the expression of inflammatory factors. In an LPS-induced microglial inflammation model, cells were transfected with either WT or glycosylation-site mutant (S117A) CXCL16 plasmid. The levels of inflammatory cytokines IL-1β, IL-6, and TNF-α in the cells were measured by ELISA. BV2 cells were transfected for TMEM260 overexpression or knockdown. The groups included Control, si-NC, si-TMEM260, NC-OE, and TMEM260-OE, and the following analyses were performed: (I) Western blot analysis was used to detect the expression of TMEM260 and CXCL16 proteins ( n = 3). (J) CHX assay was performed to evaluate the stability of CXCL16 protein. LPS-treated BV2 cells were used to conduct KANK4 overexpression and TMEM260 knockdown rescue experiments, with six groups: Control, LPS, LPS + OE-NC, LPS+KANK4-OE, LPS+KANK4-OE + si-NC, and LPS+KANK4-OE + si-TMEM260. The following analysis was conducted: (K) Western blot analysis was performed to measure CXCL16 protein expression in BV2 cells ( n = 3). For overexpression of TMEM260 and CXCL16 in LPS-treated BV2 cells, the groups included: Control, LPS, LPS + OE-NC, LPS+TMEM260-OE, LPS+TMEM260-OE + OE-NC, and LPS+TMEM260-OE+CXCL16-OE. The following analyses were carried out: (L) Western blot analysis was conducted to detect TMEM260 and CXCL16 protein levels in each group ( n = 3). (M) CCK-8 assay was applied to evaluate microglial cell viability across groups. (N) IF staining was performed to assess the expression of Iba-1 (green) and CD11b (red), indicating microglial activation status (Scale bar = 50 μm). * P < 0.05, ** P < 0.01, *** P < 0.001 vs. LPS/LPS + OE-NC/LPS+TMEM260-OE + OE-NC; ns, no significant difference vs. LPS/Control

![(A) <t>CXCL16</t> mRNA expression in the kidney during MuPyV infection. Expression is shown as fold change relative to sham infected samples. Data are from three independent experiments (n = 10-11). (B) Expression of NKCC2 [marks the ascending loop of Henle ], CD8, and CXCL16 in epithelia in sham-infected and 8 dpi kidneys; bottom right photomicrographs are merged images. Representative of two independent experiments. (C) CXCL16 expression in sham-infected, 4 dpi, and 8 dpi kidney lysates (left). Western blot image is representative of two independent experiments with each lane indicating protein lysate from kidneys of individual mice. Protein band intensity quantification for sCXCL16 was normalized to β-actin and analyzed by ImageLab and normalized to the loading control (right). Data are combined from two independent experiments (n = 3-5). (D) Experimental design of in vivo CXCL16 mAb administration. Mice were administered 250 µg of CXCL16 mAb or control rat IgG every two days from days 4-14 post infection and euthanized at 15 dpi. Numbers of CD45 mAb i.v.-negative, CD8 + CD44 + D b -LT359 tetramer + T cells and CD4 + CD44 + T cells in kidneys and spleens of infected mice given anti-CXCL16 or control rat IgG. Data were analyzed by one-way ANOVA (A and C) and by multiple Mann-Whitney tests (D).](https://pub-med-central-images-cdn.bioz.com/pub_med_central_ids_ending_with_2244/pmc11922244/pmc11922244__ppat.1012969.g002.jpg)
