TYK2 inhibitors repress IFNα signalling and inflammatory gene expression and reduce β cell immunogenicity . Dispersed human islet cells were allowed to rest in culture for two days before pre-treatment for 2 h with the indicated concentrations (expressed in mM) of TYK2i BMS-986165. Treatment was continued with BMS-986165 in the absence or presence of IFNα (2000 U/mL), IFNα (2000 U/mL) + TNFα (1000 U/ml), or IFNα (2000 U/mL) + IL-1β (50 U/mL) for 24 h. ( a–f ) Western blotting of protein lysates was performed to detect phospho-STAT1/2. Data were normalised to the levels of β-actin and expressed relative to treatment with IFNα alone. ( g ) Apoptotic cells were identified by Hoechst 33342 and propidium iodide staining. ( h–l ) Total RNA was extracted and mRNA levels of ( h ) DDIT3 ( CHOP ), ( i ) ATF3 , ( j ) CXCL10 , ( k ) MX1 , and ( l ) HLA-ABC were analysed by RT-qPCR. ( m ) Schematic representation of the experimental workflow on EndoC-βH1/HLA-A2 cells co-cultured either with HLA-A2 alloreactive or autoreactive CD8+ T cell clones directed against insulin defective ribosomal product and/or preproinsulin specific T cells.

( o ) Surface expression of HLA-ABC and ( p ) HLA-A2 in EndoC-βH1/HLA-A2 cells prior to co-culture. Cells were exposed to IFNɑ in the presence or absence of BMS-986165 for 24 h. T cell activation assay (MIP-1β release) after co-culture with (q) A2 alloreactive T cells, ( r) autoreactive T cells directed against insulin defective ribosomal product, or (s) preproinsulin specific T cells. For RT-qPCR analysis, expression data were normalised by the geometric mean of GAPDH and ACTB expression levels and expressed relative to cells exposed to IFNα alone. Statistical analyses for human islet studies (n = 3–7) were conducted using one-way ANOVA with multiple comparisons between treatment groups. Co-culture experiments were performed with independent biological replicates (n = 3). An unpaired t-test (with or without Welch's correction) was applied to evaluate the expression of surface proteins (panels n, o, and p), while one-way ANOVA with multiple comparisons was used to analyse differences between treatment conditions (all remaining panels excluding a, d, and m). All data are presented as the mean with 95% confidence intervals (CI).

TYK2 inhibition reduces the onset of diabetes in the RIP-LCMV-GP mouse model of T1D . ( a ) Male RIP-LCMV-GP mice were inoculated at 8 weeks of age with LCMV stock (0.5 × 10 5 PFU I.P., Armstrong strain), and blood glucose levels were measured pre-inoculation (Pre) and on days 1, 4, 7, 11, and 14 post-inoculation. Mice were pre-treated with either vehicle or TYK2i BMS-986202 (30 mg/kg/day) for 2 days prior to inoculation, and treatment continued until the study end on day 14. n = 18 mice/group. Vehicle- and TYK2i-treated groups are shown in grey and red symbols or bars, respectively. ( b ) Kaplan–Meier diabetes incidence plot for vehicle- and TYK2i-treated groups. ( c ) Blood glucose levels of vehicle- and TYK2i-treated mice. All blood glucose data are presented as mean with 95% CI, with individual data points represented: significant differences determined by Log-rank (Mantel–Cox) test.

TYK2i treatment preserves pancreatic β cells and inhibits the expression of IFNα-induced mRNAs in RIP-LCMV-GP mice . Pancreas tissue was harvested from vehicle- and TYK2i-treated RIP-LCMV-GP mice on days 3, 7, and 14 post-inoculation. Single-molecule fluorescence in situ hybridisation (smFISH) detecting Cd274 , Mx1, Cxcl10 , and Stat1 was performed in combination with co-staining of insulin protein and DAPI for nuclear labelling. mRNA expression in individual insulin-positive β cells was quantified following an established pipeline (details are provided in Methods).

TYK2 inhibition mitigates diabetes onset and IFNɑ responses in female NOD mice . ( a ) Six-week-old female NOD mice were treated with vehicle or TYK2i (BMS986202, 30 mg/kg) by oral gavage once daily for six weeks and monitored for diabetes onset (n = 34 vehicle/32 TYK2i). A separate cohort of NOD mice (n = 9 per study condition) was sacrificed at the end of TYK2i dosing (12 weeks of age) for tissue analysis. Blood glucose levels were measured weekly from 6 weeks until diabetes conversion (14 weeks) and biweekly until the end of the study time point. Diabetes was defined as blood glucose levels of ≥250 mg/dL in two consecutive measurements. ( b–c ) Representative images of insulin immunohistochemistry and insulitis scoring (mean with 95% CI). The stacked bars represent the percentage of different grades of immune cell infiltration across vehicle- and TYK2i-treated NOD mice. ( d ) Kaplan–Meier diabetes incidence plot.

( h ) Quantitation of mRNA copy numbers of Cd274 , Cxcl10 , Stat1 , and Mx1 in β cells. ( i ) Spatial analysis of RNA localisation between nuclear and cytoplasmic cellular compartments. For diabetes incidence studies, statistical analysis was performed by Log-rank (Mantel–Cox) test for the Kaplan–Meier plot. Wilcoxon rank sum tests were used to determine the effect of TYK2 inhibition on immune cell infiltration presented as an insulitis score. For smFISH, individual β cell measurements of RNA copy are presented, RNA localisation data are expressed as mean ± SD, and the Mann–Whitney U test was used to determine statistical differences.
