Spatiotemporal analysis of retinal Il-1 beta protein levels following LD.A-G: Immunohistochemical assessment of Il-1 beta expression (green) in retinal cryosections over the course of LD. A: Immunoreactivity (IR) for Il-1 beta protein was not observed in dim-reared animals. B-D: Il-1 beta -IR was present among ramified nuclei situated within the ONL and OS (arrowheads) immediately following exposure to 24hrs LD. E-F: Il-1 beta -IR co-localised with IBA1+ cells (red) situated in the ONL/OS, though was not apparent in IBA1+ cells outside the vicinity of the ONL (asterisks). G-H: Il-1 beta -expressing cells (H, arrowheads) did not show any discernible IR for the M2 marker CD206 (red). I: Negative control sections, in which the primary antibody was omitted, did not show any resemblance to the IR for Il-1 beta evidenced in C-D at 24hrs LD. J: ELISA for Il-1 beta protein indicated an increased abundance of the protein immediately after 24hrs LD (P<0.05), and which was virtually undetectable at all other time points. C, choroid; GCL, ganglion cell layer; INL, inner nuclear layer; IHC, immunohistochemistry; ONL, outer nuclear layer; OS, outer segments; RPE, retinal pigment epithelium. The trend in ELISA protein levels was significant by ANOVA (P < 0.05); N = 3 for each timepoint.

Spatiotemporal analysis of retinal CD206 protein levels following LD.A-L: investigation of CD206 immunoreactivity (IR, green) in retinal cryosections over the course of LD. A-B: In dim-reared animals, immunoreactivity (IR) for Il-1 beta protein was occasionally observed within nuclei (arrowheads) amongst the choroid (A) and ciliary body (B). C-E: Following 24hrs LD, CD206+ nuclei appeared from the ciliary body (C-D, arrowheads) and among the superficial retinal vasculature (E, arrowhead) F: At 24hrs LD, CD206+ cells were also more abundant within the ciliary body (arrowheads). G-I: There was increased abundance of CD206+ nuclei among optic nerve head (G-H) and superficial retinal vasculature (I) after 3 days post-exposure (arrowheads), compared to 24hrs LD. J: CD206+ cells were occasionally found accumulating within the choroid at 7 days post-exposure (arrowheads). K-L: All IR for CD206 was found to correlate with circular IBA1+ cells (red). M-N: CD206-expressing cells (N, arrowhead) did not show any detectable IR for the M1 marker Il-1 beta (red). O: Quantification of CD206 protein levels in retinas via ELISA. At 3 and 7 days post-exposure, the levels of CD206 protein were significantly higher compared to dim-reared controls (P<0.05). Progressive increases were observed during the post-exposure period, though this was not significant between 3 and 7 days (P>0.05). C, choroid; GCL, ganglion cell layer; INL, inner nuclear layer; IPL, inner plexiform layer; IHC, immunohistochemistry; ONL, outer nuclear layer; OS, outer segments; RPE, retinal pigment epithelium.

Correlation of CD206 and Il-1 beta immunolabelling within the CD11b+ macrophage population following LD.A: Representative flow cytometry plots examine CD206+ and Il1b+ cell counts within the CD11b population following light damage. For the most part, Il-1 beta and CD206 cells occupied mutually distinct subsets within the population CD11b cells. B: Quantification of Il-1 beta +/CD206- and CD206+/Il-1 beta - cells as percentage of the CD11b+ population following LD. There was a sharp increase in the proportion of Il-1 beta +/CD206- cells immediately following 24hrs LD (P<0.05), though this then decreased dramatically afterward and was similar to control samples by 7 days (P>0.05). For CD206+/Il-1 beta - cells, there was no change in their proportion at 24hrs LD (P>0.05). At 3 days post-exposure however the proportion of CD206+/Il-1 beta - cells had tripled (P<0.05), though this was then reduced to near control proportions by 7 days post-exposure (P<0.05). The trend of both Il-1 beta +/CD206- and CD206+/Il-1 beta - cells across the time course were significant by ANOVA (P < 0.05); N = 5 for each timepoint.

NBP1-42767

Immunohistochemistry: IL-1 beta/IL-1F2 Antibody [NBP1-42767] - Analysis of Mouse Embryonic Kidney Tissue: Mouse Embryonic Kidney Fixation: FFPE buffered formalin 10% conc Ag Retrieval: Heat, Citrate pH 6.2. Pressure Cooker Primary antibody: 2ug/ml 1.5 hour @ room T Secondary Ab: MACH 1 HRP POLYMER 1:50 45C RT

Western Blot: IL-1 beta/IL-1F2 Antibody [NBP1-42767] - Analysis using the Biotin conjugate of NBP1-42767. Detection of Lane 1: Mouse IL-1beta Recombinant Protein. Load: 50 ng per lane. Used at a dilution of 1:1,000 overnight at 4C.

Western Blot: IL-1 beta/IL-1F2 Antibody [NBP1-42767] - Detects 10% of the non-denatured (native) precursor 31,000 MW mouse IL-1Beta containing samples but will primarily detect all of the 17,000 MW mature molecule. However, in western blot analysis, the usual procedure of heating the sample in SDS with or without reducing agents will facilitate denaturing of the 31,000 MW IL- 1Beta precursor molecule. Denatured IL-1Beta will have a 18 kDa band.

This antibody will recognize 10% of the non-denatured (native) precursor 31,000 MW mouse IL-1beta containing samples but will primarily detect all of the 17,000 MW mature molecule. However, in western blot analysis, the usual procedure of heating the sample in SDS with or without reducing agents will facilitate denaturing of the 31,000 MW IL- 1beta precursor molecule. Denatured IL-1beta will have a 18 kDa band.

HIV Vpu and gp41 play a role in inflammasome activation.Monocyte derived macrophages (MDMs) (1 x 106) were either left untreated or transfected with 2μg of pVpu plasmid expressing Vpu or pgp41 or gp120 plasmid expressing gp120. Supernatants were collected and tested for IL-1 beta and IL-18 secretion at 12 hr (A) and 24 hr (B). Cells extracts at 12 hr from mock or transfected cells were analysed for the presence of caspase-1 p20 by western blotting, followed by quantification using Image Studio Lite (Licor) and normalized to internal control ( beta -actin) from 3 western blots(C). MDMs expressing gp41 (D) or Vpu (E) monocytes were silenced for TLR2, TLR3, TLR4 and TLR8 by siRNA. Supernatant was collected at 12 hr and analysed for IL-1 beta and IL-18 using ELISA. Cell extracts of MDMs stimulated with either Vpu (F) or gp41 (G) were analysed for the presence of pro-IL-1 beta , pro-IL-18, cleaved IL-1 beta or cleave IL-18 by western blotting, followed by quantification using Image Studio Lite (Licor) and normalized to internal control ( beta -actin) from 3 western blots. MDMs expressing Vpu (H-J), gp41 (K-M) or pgmock (N-P) were silenced for NLRP3, NLRP1, NLRC4 or NLRP3 and NLRC4 by siRNA. Supernatant was collected at 12 hr and analysed for IL-1 beta (Η, Κ, Ν) and IL-18 (I,L,O) using ELISA. All graphs were normalized to the level of siRNA knockdown. Cells extracts were analysed for the presence of caspase-1 p20 at 12 hr by western blotting, followed by quantification using Image Studio Lite (Licor) and normalized to internal control ( beta -actin) from 3 western blots (J,M,P). The data represent the mean of three independent experiments +/- SD (n = 3 sets of macrophages) yielding consistent results. **, p < 0.005 and ***, p < 0.001 indicate statistically significant differences.
