Aspirin-based PROTACs as COX-2 degraders for anti-inflammation.

Cyclooxygenase-2 (COX-2) is a key enzyme in the biosynthesis of prostaglandins and plays a special role in the process of inflammatory response. COX-2 is a target of non-steroidal anti-inflammatory drugs (NSAIDs), which can effectively relieve inflammation, pain and fever responses by inhibiting COX-2. Despite the significant study progress of inhibitors targeting COX-2, the development of COX-2 degraders remains insufficient.

Nano hydroxyapatite-silica with a core-shell structure for long-term management of dentin hypersensitivity.

Teeth undergo continuous demineralization and remineralization influenced by dietary acid and saliva. Excessive dietary acid attack disrupts this balance, exposing dentin tubules and causing dental hypersensitivity (DH). Due to low acid resistance, traditional anti-DH regents such as calcium phosphate minerals fail in long-term occlusion of dentin tubules, resulting in recurrent attacks of DH.

Hepatitis B core virus-like particles bearing Pgp3 antigen enhance immune response against genital chlamydial infection in mice.

Chlamydia trachomatis Pgp3 protein-induced immunoprotection is effective but incomplete, which requires the suitable adjuvants to enhance its immune response. Within this context, Hepatitis B core virus-like particles (HBc-VLP) emerge as nanoscale protein particles capable of incorporating either endogenous or exogenous antigens or epitopes. In this study, HBc-Pgp3 chimeric protein was accomplished by integrating the identified dominant epitope of the Pgp3 protein into the major immunodominant region of a truncated HBc-VLP, which was realized in the pET28a (+) vector and expressed via the E.
