Summary: Inflammatory bowel disease (IBD) is a growing concern for global health due to its increasing incidence rate. Medicinal plants and nanoparticles have shown potential in IBD treatment, but their limitations hinder clinical application. Nanoparticles and extracellular vehicles (EVs) offer advantages in drug delivery to the colon, promoting anti-inflammation and improving intestinal health. Clinical trials evaluating the safety and effectiveness of EVs-loaded drugs in IBD are underway. This review discusses the role of synthetic nanoparticles and medicinal plants derived EVs in IBD treatment and highlights limitations and future research needs.

Summary: Inflammatory bowel disease (IBD) is a common inflammatory disorder affecting the gastrointestinal tract. Alginate (AG), as a marine-derived polysaccharide, has been extensively studied for its properties in drug delivery systems for IBD treatment. AG-based carrier systems, including nanotechnology-based systems and hydrogels, have shown potential in targeted drug delivery and tissue regeneration. This review focuses on the pathogenesis of IBD, currently studied medications, AG-based drug delivery systems, and their properties for alleviating IBD.

Summary: The current clinical treatments for inflammatory bowel disease (IBD) suffer from severe side effects, low long-term treatment efficacy, and increased risks of infection and malignancy. However, naturally bioactive small molecules, reactive oxygen species scavengers, and gut microbiota modulators have emerged as promising candidates for IBD treatment. Polymeric systems have been engineered as delivery vehicles to improve the bioavailability and efficacy of these therapeutic agents, while reducing their systemic toxicity. This article surveys polymer-derived drug delivery systems for combating IBD.

Summary: The complex pathogenesis of inflammatory bowel disease (IBD) presents challenges for finding an effective cure. Current therapeutic protocols focus on reducing inflammation or maintaining remission, but drugs often have severe side effects or limited bioavailability in the inflamed regions. Researchers have explored the use of nanoparticulate drug delivery systems and polysaccharides for targeted treatment of inflamed tissues, but challenges such as high costs and primary nonresponse remain. This critical review discusses the advances in IBD treatment and reviews the use of polysaccharide nanoparticulate drug delivery systems for IBD treatment.

Summary: Inflammatory bowel disease (IBD) comprises ulcerative colitis (UC) and Crohn's disease (CD) and involves immune cell alteration and chronic inflammatory cascade activation against unknown environmental triggers. Therapy focuses on supporting measures and use of anti-inflammatory and immunosuppressive drugs, with glucocorticoids (GCs) being a cornerstone treatment for moderate-to-severe IBD. However, their use is limited by important adverse drug effects, leading researchers to explore newer, safer alternatives.

Summary: The study revealed the presence of multiple isoforms of human Dectin-1, compared to only two forms in mice. Transfecting the Dectin-1 gene into non-expressing cells showed effective suppression of the target gene expression through beta-glucan/Dectin-1-mediated uptake. This suggests that the beta-glucan complex can be a useful tool for delivering antisense oligonucleotides to Dectin-1-expressing cells in both mice and humans.

Summary: Proteins and nucleic acids derived from bioresources have shown potential as a new medical modality. In this study, conjugates of bovine serum albumin (BSA) and hyaluronic acid (HA) were prepared to deliver proteins to cancer cells. The conjugates, with a highly condensed structure and crosslinking through BSA, induced a larger decrease in frequency change and showed high fluorescence intensity in CT26 cells. These conjugates and nanoparticles with densely packed HA structures could serve as an effective platform for delivering proteins to cancer tissues.

Summary: Recent studies have demonstrated the strong efficacy of peptide-based vaccines for cancer immunotherapy. Co-delivering adjuvant and antigenic peptide molecules to antigen-presenting cells simultaneously can optimize immunological performance. However, the conjugate consisting of 30-mer CpG-DNA and a cancer antigenic peptide of TRP2(180-188) did not induce efficient TRP2(180-188)-specific immune responses in mice.
