This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

This review discusses the brain-skin connection, the skin's role in stress response, and highlights unmet challenges in understanding stress-induced skin inflammation but reports no new experimental findings.

This review discusses the potential of nanocarriers to enhance transdermal drug delivery and the combination of these carriers with physical methods, but it reports no new experimental results.

This study found that distinct isoenzymes of 3 beta-hydroxysteroid dehydrogenase are expressed in human adrenals and gonads compared to the placenta and skin.

This article reviews the role of stromal stem cells in mammalian wound repair, suggesting they may perform functions similar to blastemal cells in simpler organisms, but reports no new experimental results.

In this study, researchers found that mouse hair follicles recruit Langerhans cells by secreting chemokines, acting as key portals for these cells in both mice and humans.

This study observed that acute stress in rats increased neurosteroid levels linked to enhanced GABA(A) receptor function, raising seizure thresholds, while similar effects were seen in mice with deoxycorticosterone administration.

This study found that sebaceous-gland-derived glycerol significantly contributes to stratum corneum hydration in mice with sebaceous gland deficiencies.

This study reports a novel LC/MS method that separates and analyzes all known ceramide subclasses in human stratum corneum, identifying a new subclass, CER [EOdS], with minimal sample preparation.

This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.

This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.

This review examines the histochemistry and keratinization processes of human hair, exploring the structural roles of keratin proteins, protein chains, and lipids, but offers no new results.

This article reviews the structure and function of the skin and its importance for understanding skin diseases, without providing new clinical results.

The researchers reported that they predicted associations between certain components of MSC-conditioned medium and its ability to stimulate cell migration in vitro, identifying factors affecting its biological activity.

This study suggests that stress negatively affects hair growth by inducing inflammation and early hair cycle transitions in mice, which might inform strategies for managing stress-related hair loss in humans.

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 study found that an oil-in-water microemulsion of curcumin penetrated deeper into the human stratum corneum and hair follicles compared to an amphiphilic cream.

This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This article discusses the structure of the human type II 5 alpha-reductase gene and reports no new experimental results.

In this study, terbinafine reached high concentrations in stratum corneum and sebum after oral administration, with drug levels remaining above fungicidal concentrations for over three weeks.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.

This review suggests that allogenic adipose stem cell and extracellular matrix transplants may be safe and effective for various medical conditions, based on available studies.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study reports that human eccrine sweat gland cells are capable of forming a stratified epidermis, suggesting they may serve as an additional source of keratinocytes for skin repair.

This article discusses the role of stratum corneum disruption in dandruff and suggests that treatments improving scalp barrier integrity along with antifungal activity may be beneficial; it reports no new research findings.

This study found that hair cortisol concentration in free-ranging brown bears is influenced by handling methods, body condition, and potentially both short- and long-term stressors.
