Description
While the study shows rhein hydrogels bind TLR4, it’s unclear whether self-assembly into hydrogels enhances, maintains, or reduces the drug’s receptor binding properties. This knowledge gap limits optimization of hydrogel-based drug delivery systems.
Gap type: open_question Source paper: Directed self-assembly of herbal small molecules into sustained release hydrogels for treating neural inflammation. (2019, Nature communications, PMID:30962431)
