Transplantation of peripheral nerve tissueoid based on a decellularized optic nerve scaffold to restore rat hindlimb sensory and movement functions.

Peripheral nerve injury (PNI) involving the loss of sensory and movement functions is challenging to repair. Although the gold standard of PNI repair is still the use of autologous nerve grafts, the destruction of the donor side is inevitable. In the present study, peripheral nerve tissueoids (PNTs) composed of a Schwann cell (SC)-based neurotrophin-3 (NT-3) delivery system and a decellularized optic nerve (DON) with naturally oriented channels were engineered to investigate the mechanism of PNTs in nerve regeneration.

A multifunctional cascade gas-nanoreactor with MnO as a gatekeeper to enhance starvation therapy and provoke antitumor immune response.

Glucose oxidase (GOx)-mediated starvation therapy is an effective tumor treatment that blocks energy and activates the immune response.
