Abstract:
Fibroblast activation protein (FAP), scarcely expressed by fibroblasts in normal tissue, is highly expressed in activated fibroblasts, which are commonly associated with chronic inflammation and in cancer microenvironment. FAP is being explored as a therapeutic target for the treatment of fibrotic pathology. Here, we describe an FAP mRNA encapsulated in lipid nanoparticles (FAP mRNA-LNP) for use as a vaccine to attenuate the severity of experimental arthritis. This FAP mRNA-LNP vaccine may have a broader application, such as therapy for cancer and other fibrotic conditions.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
