This study found that daily consumption of soft drinks significantly increases the risk of moderate-to-severe acne in adolescents, particularly if sugar intake from these drinks exceeds 100 grams per day.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Cathepsin L deficiency causes hair and skin issues in mice.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

This review provides a synopsis of 53 cases of temporal triangular alopecia, noting its frequent detection in early childhood and potential association with congenital diseases, but it reports no new clinical findings.

This study demonstrated that hair follicle-derived cells can induce hair follicle formation in an in vitro skin organ culture system using human retroauricular skin specimens.

This research explores developing liposomal formulations to enhance the delivery of difficult-to-absorb agents directly to hair follicles and sebaceous glands, with minoxidil and plasmid DNA as study molecules.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

This study reports various immunophenotypical patterns in apocrine mixed skin tumors, resembling the structures of hair follicles, sebaceous glands, and apocrine glands.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.

In this mouse study, the researchers found that the monoclonal antibody ME1 causes hair follicle inflammation by up-regulating TNFα, which can be reduced by TNFα and interleukin-1 inhibitors.

This review highlights that idiopathic hirsutism is characterized by local hyperandrogenization affecting hair growth, without other signs of hyperandrogenism, and shows no new results; racial differences in prevalence are noted but not in androgenic steroids.

This review discusses common skin appendage diseases, including their pathophysiology and treatments, but does not report new results.

In this study, the authors observed that cell-mediated immune mechanisms may be involved in the pathogenesis of benign follicular mucinosis, based on the cellular and immunological characteristics of two patient cases.

This review discusses the various roles of RANK signaling in bone remodeling, immune function, and epithelial differentiation, highlighting its potential involvement in cancer mechanisms; it reports no new clinical results.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

In this study, the combination of keratin-gelatin from poultry feathers promoted early acceptance and viability of full-thickness skin mesh grafts in experimental dogs compared to other treatments.

This review discusses the clinical manifestations of malnutrition in children, particularly highlighting the overlapping skin changes from various nutrient deficiencies, and reports no new clinical results.

This report suggests that clinically inapparent sweat gland tumors might influence hair loss in a specific patient case.

This case report describes a patient who developed alopecia after 18 weeks of treatment with dupilumab for atopic dermatitis.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This study found that the co-ablation of C/EBPalpha and C/EBPbeta in adult mouse skin disrupted sebocyte differentiation and epidermal homeostasis, highlighting their critical roles in these processes.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

This study observed that retinoic acid biosynthesis and signaling in hair follicles have a spatial and temporal regulation linked to distinct stages of the hair cycle in mice.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

This study found that EGF receptors are aberrantly regulated and persist in cholesteatoma epithelium, suggesting a hyperproliferative character compared to normal human skin.

This systematic review and meta-analysis reported potential risk variants for acne in genes related to inflammation and sebaceous gland function, including TNF, CYP17A1, and FST, across diverse populations.

This review revisits mechanisms underlying acne lesion formation and suggests that preventing comedone development requires controlling critical factors in the pilosebaceous follicle before acne involvement.

This study showed that Thujae occidentalis semen extract inhibited 5alpha-reductase type 2 in laboratory tests and reduced androgen-related hair loss in animal models, suggesting potential use for male pattern baldness.
