A Roadmap of Peptide-Based Materials in Neural Regeneration.

Injuries to the nervous system lead to irreversible damage and limited functional recovery. The peripheral nervous system (PNS) can self-regenerate to some extent for short nerve gaps. In contrast, the central nervous system (CNS) has an intrinsic limitation to self-repair owing to its convoluted neural microenvironment and inhibitory response.

Exploring the mechanism of tetramethylpyrazine in the treatment of osteoarthritis based on network pharmacology.

Background: Osteoarthritis (OA) is the most common joint disease, which mainly damages articular cartilage and involves the whole joint tissue. It has the characteristics of long course, repeated symptoms and high disability rate, and the incidence trend is gradually increasing. Tetramethylpyrazine (TMP) is the main alkaloid active substance in Ligusticum wallichii, a traditional Chinese medicine, which has the effect of promoting blood circulation and dredging collaterals, and has a good effect on the treatment of early OA, but its molecular mechanism has not been fully clarified so far.

Upregulation of C1QC as a Mediator of Blood-Brain Barrier Damage in Type 2 Diabetes Mellitus.

The blood-brain barrier (BBB) is a neurovascular structure that safeguards the brain by inhibiting the passage of harmful substances. In individuals with type 2 diabetes mellitus (T2DM), the heightened blood glucose may cause damage to endothelial cells and neurons, increase collagen protein content, and elevate BBB permeability. Although the impact of blood glucose regulation on the structure and function of BBB has been documented, the exact mechanism remains incompletely elucidated.
