An increasing number of studies suggest that TBI-induced oxidative stress and neuroinflammatory sequelae (especially, inflammation in the hippocampus region) may lead to the development of PTE. Due to the blood–brain barrier (BBB), typical systemic pharmacological therapy for TBI cannot deliver berberine (BBR) to the targeted location in the early stages of the injury, although BBR has strong anti-inflammatory properties. To break through this limitation, a microenvironment-responsive gelatin methacrylate (GM) hydrogel to deliver poly(propylene sulfide)<sub>60</sub> (PPS<sub>60</sub>) and BBR (GM/PB) is developed for regulating neuroinflammatory reactions and removing reactive oxygen species (ROS) in the brain trauma microenvironment through PPS<sub>60</sub>.

To mimic this behavior, binary compositions of collagen, elastin, and fibrin are fabricated in a 1:1 ratio, resulting in the formation of Col/Ela, Col/Fib, and Ela/Fib composites through a customized fabrication procedure. The physical properties of these scaffolds are comprehensively analyzed using a range of material characterization techniques.

The findings of the study demonstrate that the utilization of binary combinations of Col/Ela, Col/Fib, and Ela/Fib has a discernible impact on the physical and biological characteristics of the scaffolds.

Here, water-insoluble beclometasone dipropionate (BDP) which is a potent anti-inflammatory therapeutic agent but limited to topical applications so far, is encapsulated. Therefore, this work used an amphiphilic block copolymer self-assembling into flexible polymeric filomicelles, which have recently proven to selectively target inflamed areas in patients with inflammatory bowel disease (IBD). The small diameter and flexibility of these filomicelles is considered beneficial for transepithelial passages, while their length minimizes the unspecific uptake into nontargeted cells. This work successfully establishes a protocol to load the water-insoluble BDP into the core of the filomicelles, while maintaining the particle stability to prevent any premature drug release. The anti-inflammatory efficacy of BDP-loaded filomicelles is further investigated on lipopolysaccharide (LPS) stimulated human monocytes. In these ex vivo assays, the BDP-loaded filomicelles significantly reduce TNF-α, IL-6, IL-1ß, IL-12p70, IL-17a, and IL-23 release after 24 h. Additional time course study of drug-loaded filomicelles and their comparison with a common water-soluble and unspecific corticosteroid demonstrate promising results with significant immune response suppression in stimulated monocytes after 2 and 6 h.
