Figure Lengend Snippet: Immunohistochemical profiling of HTT inclusion body ubiquitination and associated triage protein binding in the HD human middle temporal gyrus. Multiplexed immunohistochemical approaches were used to identify HTT inclusion bodies, ubiquitin species, and triage proteins in neurologically normal and HD human middle temporal gyrus tissue microarray cores. Example images from HD case, HC150, are shown. HTT inclusion body antibodies, EM48 ( A ), EPR ( B ), and MW1 ( C ), were used for labelling together with antibodies for pan-ubiquitin ( D ), K48- and K63-linked polyubiquitination ( E and F ), p62 ( G ), and ubiquilin 2 ( H ), with a Hoechst nuclear counterstain ( I ); scale bars = 20 μm.

Article Title: Huntingtin inclusion bodies have distinct immunophenotypes and ubiquitination profiles in the Huntington’s disease human cerebral cortex

doi: 10.1038/s41598-025-00465-w

Figure Lengend Snippet: HTT inclusion bodies are not frequently ubiquitinated, but when ubiquitinated, are predominantly ubiquitinated by K63-linked ubiquitin. Immunohistochemical labelling revealed that EM48, EPR, and/or MW1 HTT inclusion bodies were ubiquitinated by K48- and/or K63-linked ubiquitin ( A ); a representative image of K48- and K63-ubiquitinated HTT inclusion bodies from HD case, HC145, is shown; scale bars = 10 μm. The ubiquitination status of each HTT inclusion body was determined by labelling for pan-, K48-, and K63-linked ubiquitin, where positive labelling was identified if the maximum intensity was above manually determined thresholds. The percentage of EM48 + versus EM48- ( B ), EPR + versus EPR- ( C ), and MW1 + versus MW1- ( D ) HTT inclusion bodies that were ubiquitinated (either pan, K48-, and/or K63-linked) were compared using a Wilcoxon matched-pairs signed rank test. The percentage of ubiquitinated HTT inclusion bodies was determined for each EM48, EPR, and MW1 +/- phenotype per HD case ( E ), and compared between phenotypes using a mixed-effects analysis, with Geisser-Greenhouse correction and Tukey’s multiple comparisons test. The percentage of ubiquitinated HTT inclusion bodies ubiquitinated by K48- versus K63-linked ubiquitin was compared using a Wilcoxon matched-pairs signed rank test ( F ). The percentage of ubiquitinated EM48 + versus EM48- ( G ), EPR + versus EPR- ( H ), and MW1 + versus MW1- ( I ) HTT inclusion bodies ubiquitinated by K48- versus K63-linked ubiquitin were compared using an ordinary two-way ANOVA with Tukey’s multiple comparisons test. The percentage of EM48, EPR, and MW1 +/- immunophenotypes HTT inclusion bodies identified as being ubiquitinated by K48- or K63-linked chains were compared using an ordinary two-way ANOVA with Sidak’s multiple comparisons test ( J ). Data are presented as truncated violin plots ( n = 20). Statistical significance of differences shown for B-D and F-J: * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001, **** p ≤ 0.0001. Statistical significance for E is shown in Supplementary Table 3.

Figure Lengend Snippet: Summary of HTT inclusion body characteristics. Heatmap organised by HTT inclusion body phenotype, with each column representing a single case and each bar coloured according to that case’s value for the characteristic outlined by the row title ( A ). Schematic illustrating the general characteristics of each HTT inclusion body phenotype: (1) EPR + MW1 + inclusion bodies are more frequently located in the nucleus compared to other phenotypes, (2) HTT inclusion bodies that label for more than one epitope-specific antibody are more frequently ubiquitinated, and that ubiquitination occurs more frequently by K63- compared to K48-linked ubiquitin chains, (3) Ubiquitinated HTT inclusion bodies are more frequently tagged by ubiquilin 2 than p62 ( B ). Schematic summarising our hypothesis of HTT inclusion body immunophenotype, ubiquitination, and triage protein tagging with increasing HD severity ( C ); created in BioRender.
