Fibrotic diseases remain a substantial health burden with few therapeutic
approaches. A hallmark of fibrosis is the aberrant activation and accumulation
of myofibroblasts, which is caused by excessive profibrotic cytokines.
Conventional anticytokine therapies fail to undergo clinical trials, as simply
blocking a single or several antifibrotic cytokines cannot abrogate the
profibrotic microenvironment. Here, biomimetic nanoparticles based on
autologous skin fibroblasts are customized as decoys to neutralize multiple
fibroblast-targeted cytokines. By fusing the skin fibroblast membrane onto
poly(lactic-co-glycolic) acid cores, these nanoparticles, termed fibroblast
membrane-camouflaged nanoparticles (FNPs), are shown to effectively
scavenge various profibrotic cytokines, including transforming growth
factor-휷, interleukin (IL)-11, IL-13, and IL-17, thereby modulating the
profibrotic microenvironment. FNPs are sequentially prepared into multiple
formulations for different administration routines. As a proof-of-concept, in
three independent animal models with various organ fibrosis (lung fibrosis,
liver fibrosis, and heart fibrosis), FNPs effectively reduce the accumulation of
myofibroblasts, and the formation of fibrotic tissue, concomitantly restoring
organ function and indicating that FNPs are a potential broad-spectrum
therapy for fibrosis management.

1. Introduction
Fibrosis, or disordered fibrotic tissue formation, is characterized by the abnormal
fibroblast activation that induces excessive extracellular matrix (ECM) remodeling
and primarily accounts for multiple organ
dysfunctions.[1] The pervasive occurrence
of fibrosis in almost all diseases generates
a large healthcare burden worldwide. However, the clinical benefits of antifibrotic therapy through small molecules, such as pirfenidone and nintedanib, are usually offset
by their modest therapeutic efficacy, limited
indications and severe side effects.[2] Therefore, alternative clinical intervention modalities to target fibrosis are urgently needed.
Considering the central role of myofibroblast activation and proliferation in
fibrosis establishment,[3] recent breakthroughs have focused on the ablation
of progressive myofibroblast activation
through autologous cell-based therapy.
For example, autologous chimeric antigen
