In this study, our aim was to develop liposomal formulations based on central tear film lipid species such as a phosphatidylcholine (PC), a wax ester (WE) and an O-acyl-ω-hydroxy fatty acid (OAHFA). In more detail, two liposomal formulations were developed and characterized by physicochemical techniques in vitro followed by cytotoxicity studies in vitro (human corneal epithelial; HCE cells) and tolerability studies in vivo (rats and rabbits). To obtain more insights of the potential functionality of the formulations, their ability to promote the recovery of damaged HCE cells was assessed in vitro, the residence time of WE and OAHFA from rabbit tear fluid was determined in vivo, and the permeation and distribution of these lipids in excised rabbit cornea was investigated ex vivo. Both formulations were considered well-tolerated in vitro and in vivo, and possessed acceptable features for ocular administration. Also, in vitro cell recovery studies showed promise. No considerable differences were observed between the formulations in terms of the residence time of the WE and OAHFA utilized. Moreover, the studies indicated that these lipid species may accumulate in the corneal epithelium and thereafter distribute back to the tear fluid (especially in the case of the OAHFAs) after a longer dosing period.

Though promising, immunotherapy is hindered by CCA's desmoplastic tumor microenvironment, known for its inflammatory and immunosuppressive characteristics, often termed a “cold tumor”. Previously, we reported that Poly(I:C), a TLR3 agonist, synergizes with a Smac mimetic, an IAP antagonist, to trigger necroptosis when caspase activity is blocked. In this study, we aimed to evaluate rational combination strategies to advance Poly(I:C)-based necroptosis immunotherapy in preclinical models. Transcriptomic analysis of public CCA patient datasets revealed that low expression of <em>TLR3</em>, accompanied by low <em>IFNG</em> or <em>IRF1</em> expression, is significantly associated with poorer prognosis. These findings highlight the clinical relevance of the IFN-γ/IRF1/TLR3 axis and support the development of therapies targeting this pathway. We further found that IFN-γ treatment increases TLR3 expression. Importantly, we demonstrated that IFN-γ could enhance Poly(I:C)-induced necroptosis and immunogenic cell death (ICD) when IAPs and caspases are inhibited by Smac mimetic and the pan-caspase inhibitor Z-VAD-FMK in human CCA cell lines. CU-CPT 4a, a highly selective TLR3 inhibitor, partially reduced this cell death. This indicates that the effect is mediated in part through TLR3. The combined effects were shown to depend on RIPK1/RIPK3/MLKL-induced necroptosis. Additionally, the dying cells released HMGB1, a marker of ICD, and their conditioned medium promoted dendritic cell maturation (CD80, CD86, HLA-DR), which is critical for antigen presentation and T-cell priming. From a personalized medicine perspective, <em>TLR3, IFNG</em>, and <em>IRF1</em> expression levels may serve as predictive biomarkers to guide patient selection for TLR3 agonist-based therapies.

While human faecal models are used, they suffer from practical limitations such as donor recruitment and regulatory constraints. Larger animals like dogs are often assumed to be more translationally relevant yet are resource-intensive and subject to more complex regulatory and logistical requirements. Rats offer a more accessible, cost-effective and scalable alternative. However, it remains unclear whether their faecal material alone accurately reflects colonic metabolism. Specifically, it is unknown whether faecal samples capture the same metabolic activity as more invasive caecal or colonic contents, or how closely they reflect drug degradation in larger animal models or humans. This study aimed to: (i) compare degradation of three prodrugs across Wistar rat faecal, caecal, and colonic compartments; (ii) determine how rat degradation profiles differ from those observed in Labradors; and (iii) evaluate how closely rat and canine data align with published human in vitro results. Degradation kinetics of sulfasalazine, balsalazide, and olsalazine were first assessed. Bioreactors prepared from 10% faecal, caecal, and colonic contents in rats were used. Faecal material showed equivalent metabolic activity to colonic and caecal material across all drugs (two-way ANOVA, p = 0.233), with sulfasalazine degrading most rapidly (t₁/₂ = 29.1 min), followed by balsalazide (t₁/₂ = 47.9 min), and olsalazine (t₁/₂ = 84.1 min). These findings indicate that faecal material can reliably substitute for more invasive gut content sampling, offering practical and procedural advantages. Subsequent interspecies comparisons revealed that rats exhibited significantly higher degradation rates than dogs (P &lt; 0.05), reflecting known differences in gut microbial density and composition. When benchmarked against published human in vitro data, rat degradation rates were closely aligned with human values, particularly for sulfasalazine (rat: <em>K</em> = 0.025 min⁻¹; human: <em>K</em> = 0.021 min⁻¹) and balsalazide (rat: <em>K</em> = 0.015 min⁻¹; human: <em>K</em> = 0.009 min⁻¹).
