research Mechanical Stretch Upregulates SDF-1α in Skin Tissue and Induces Migration of Circulating Bone Marrow-Derived Stem Cells into the Expanded Skin
Stretching skin increases a certain protein that attracts stem cells, helping skin regeneration.
research Transepidermal UV radiation of scalp skin ex vivo induces hair follicle damage that is alleviated by the topical treatment with caffeine
Caffeine applied to the scalp can protect hair follicles from UV damage.
research Mechanistic Approach on the Pulmonary Oxido-Inflammatory Stress Induced by Cobalt Ferrite Nanoparticles in Rats
Daily intake of 0.5 or 5 mg cobalt ferrite nanoparticles can harm lungs through oxidative and inflammatory stress.
research Skin physiology in microgravity: a 3-month stay aboard ISS induces dermal atrophy and affects cutaneous muscle and hair follicles cycling in mice
A 3-month stay in space causes skin thinning, disrupts hair growth, and changes muscle-related genes in mice.
research Comparison of MMP1 gene expression and collagen percentage in response to polydioxanone, poly-L-lactic acid and polycaprolactone thread implantation in ageing rat skin
PDO, PLLA, and PCL threads increase collagen in ageing skin but don't change MMP1 gene expression.
research K15 promoter-driven enforced expression of NKIRAS exhibits tumor suppressive activity against the development of DMBA/TPA-induced skin tumors
NKIRAS2 can suppress certain skin tumors but its effect on cancer varies with context and expression level.
research Network pharmacology and in vivo experimental analysis for validating the antifibrotic potential of Punica granatum leaves against skin scleroderma: the role of oxidative stress, inflammation and TGF-β1/Snail 1/p-Smad 3 signaling pathway
This study explores the antifibrotic potential of Punica granatum ethanolic leaf extract (PGEL) against skin scleroderma, focusing on oxidative stress, inflammation, and the TGF-β1/Snail 1/p-Smad 3 signaling pathway. In a rat model with 24 subjects, PGEL was administered at doses of 200 and 400 mg/kg, resulting in reduced oxidative stress and inflammation markers, such as IL-17 A, TNF-α, and MMP-9. PGEL also downregulated fibrotic markers like COL1A1 and Snail 1, and decreased TGF-β1 and p-Smad 3 levels, leading to improved dermal thickness and collagen fiber arrangement. The study suggests that PGEL, rich in compounds like ellagic acid and catechin-3-O-gallate, may offer therapeutic benefits for skin fibrosis by targeting inflammation, extracellular matrix production, and oxidative stress.
research Hydrogel crosslinking modulates macrophages, fibroblasts, and their communication, during wound healing
Softer hydrogels help wounds heal better with less scarring.
research Keratins and disease at a glance
Keratins are crucial for tissue strength, and mutations in keratin genes can lead to various diseases, highlighting the need for targeted therapies.
research An ERK-dependent molecular switch antagonizes fibrosis and promotes regeneration in spiny mice ( Acomys )
High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Mesenchymal stem cells could help treat aging-related diseases better than current methods.
research 616 Endoplasmic reticulum stress upregulates NKG2D ligands in the hair follicle
Stress in hair follicle cells increases certain immune-related proteins, which might contribute to hair loss conditions.
research Foot shock stress prolongs the telogen stage of the spontaneous hair cycle in a non‐depilated mouse model
Stress in mice delays hair growth and treatments blocking substance P can partly reverse this effect.
research 1318 Both lesional and non-lesional skin from acne patients shows robust IL-17-skewing and upregulation of antimicrobial peptides
Acne patients' skin, both with and without lesions, shows a strong immune response and higher antimicrobial activity.
research Estrogens and aging skin
Estrogen therapy can reduce skin aging but has cancer risks.
