This review discusses recent advances in understanding the cellular, molecular, and genetic factors contributing to lupus erythematosus and reports no new experimental findings.

This article discusses hair loss disorders in domestic animals, but it contains no abstract or new research findings.

This narrative review highlights the potential of exosomes in regenerative and aesthetic dermatology, particularly in India, but emphasizes that their clinical use is still investigational due to limited and diverse study data, insufficient long-term safety information, and regulatory challenges.

In this study, cicatricial alopecias were classified by inflammatory cell type and the researchers highlighted that primary cicatricial alopecia's exact causes remain unknown, accounting for 6% of all hair diseases despite its unclear prevalence.

This case report describes a 42-year-old woman with Rhupus, a rare overlap syndrome of rheumatoid arthritis and systemic lupus erythematosus, highlighting challenges in diagnosis due to non-specific clinical criteria and documenting specific symptoms such as inflammatory arthritis, malar rash, and hematological abnormalities observed during follow-up.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

This study suggests that rather than inhibiting IL-15, selectively stimulating IL-15Ra-mediated signaling could be beneficial for managing alopecia areata and possibly other inflammatory hair loss conditions, as IL-15 promoted hair growth and maintained immune privilege in human hair follicles.

Classifying hair diseases, like alopecia, is difficult and needs more research to understand their causes.

This study found that oral probiotic supplementation over 12 weeks may improve hair growth, skin condition, metabolic health, and stress responses in Chinese adults with hair loss and a high risk of metabolic syndrome.

This review discusses the molecular mechanisms and therapeutic effectiveness of Janus Kinase Inhibitors for inflammatory skin diseases, suggesting these inhibitors have a rapid onset and favorable safety profile compared to conventional treatments.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

This case report describes two brothers with an unusual, possibly treatment-resistant inflammatory variant of androgenic alopecia, featuring follicular isthmic lymphocytic inflammation and diffuse central scalp hair loss.

This review summarizes fundamental concepts and recent advancements in hair follicle biology, including insights from mouse models into broader molecular and cellular processes relevant to regeneration and development.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.

This study identified new dietary ligands for the human vitamin D receptor, including curcumin and gamma-tocotrienol, which may influence its biological functions.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

The authors concluded that chronic telogen effluvium in middle-aged women presents distinct clinical and histological features that differ from androgenetic alopecia and acute telogen effluvium.

This article proposes five different mechanisms for telogen effluvium, supported by clinical findings, based on changes in different phases of the hair cycle.

In a mouse model, this study demonstrated that a microneedle patch system using keratin and integrated with MSC-derived exosomes and UK5099 promoted hair regrowth more efficiently than traditional delivery methods.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

This article reviews lichen planopilaris, its presentation, and treatment challenges, and emphasizes the need for more research into its pathogenesis and therapy efficacy; it reports no new findings.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This study reports that some patients with androgenetic alopecia may also exhibit clinical and histological features of inflammation and fibrosis, similar to those found in lichen planopilaris.

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.
