Beyond Encapsulation: Exploring Macrophage-Fibroblast Cross Talk in Implant-Induced Fibrosis.

The foreign body response (FBR) and organ fibrosis are complex biological processes involving the interaction between macrophages and fibroblasts. Understanding the molecular mechanisms underlying macrophage-fibroblast cross talk is crucial for developing strategies to mitigate implant encapsulation, a major cause of implant failure. This article reviews the current knowledge on the role of macrophages and fibroblasts in the FBR and organ fibrosis, highlighting the similarities between these processes.

The Influence of Design Modifications and Microstructured Surface Topographies on Bleb Survival after Glaucoma Tube Shunt Implantation.

Lowering intraocular pressure (IOP) by placement of a glaucoma shunt is an effective treatment for glaucoma. However, fibrosis of the outflow site can hamper surgical outcome. In this study, the antifibrotic effect of adding an endplate (with or without microstructured surface topographies) to a microshunt made of poly(styrene-block-isobutylene-block-styrene) is investigated.
