Introduction: Keloids are a common skin disorder characterized by excessive fibrous tissue proliferation, which can significantly impact patients' health. Ferroptosis, a form of regulated cell death, plays a crucial role in the development of fibrosis; however, its role in the mechanisms of keloid formation remains poorly understood.
Methods: This study aimed to identify key genes associated with ferroptosis in keloid formation.
is overexpressed in keloid keratinocytes and its inhibition alters profibrotic gene expression.

Background: Keloids are disfiguring, fibrotic scar-like lesions that are challenging to treat and commonly recur after therapy. A deeper understanding of the mechanisms driving keloid formation is necessary for the development of more effective therapies. Reduced vitamin D receptor (VDR) expression has been observed in keloids, implicating vitamin D signaling in keloid pathology.

Keloid is benign skin tumor, and their curing is relatively difficult due to the unclear mechanism of formation. Inducing ferroptosis of keloid fibroblasts (KFs) may become a new method for treating keloid. Here, we discover interferon (IFN)γ could induce KFs ferroptosis through inhibiting SPOC domain-containing protein 1 (SPOCD1), serving as a mode of action for CD8T cell (CTL)-mediated keloid killing.

Disruption of the molecular pathways during physiological wound healing can lead to raised scar formation, characterized by rigid, thick scar tissue with associated symptoms of pain and pruritus. A key mechanical factor in raised scar development is excessive tension at the wound site. Recently, microneedles (MNs) have emerged as promising tools for scar management as they engage with scar tissue and provide them with mechanical off-loading from both internal and external sources.

The stress response following burns may be a crucial factor in keloid formation, yet the underlying pathological mechanisms remain to be elucidated. This study initially investigated how heat shock factor 1 (HSF1) and heat shock proteins (HSPs) within the heat shock pathway influence keloid fibrosis, providing insights into the role of the heat shock response in keloid development. This study aims to further elucidate the role of the heat shock pathway in keloid fibrosis and investigate the specific function of HSF1 within this pathway.
