This study found that the interaction between heat shock protein 90 and lamin A/C is crucial for the growth, migration, and self-aggregation of dermal papilla cells, suggesting a potential role in alopecia areata mechanisms.

This review discusses the bioactive compounds and biological activities of Polygonum multiflorum Thunb. and highlights concerns about its hepatotoxicity, but reports no new clinical results.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This study provides one of the first descriptions of the demographic, clinical, and therapeutic characteristics of lichen planopilaris in Chilean adults, reporting that treatment usually reduced or halted disease progression.

This study highlights ongoing inequities in access and outcomes for inflammatory skin diseases in Latin America and emphasizes the need for regional registries, harmonized clinical guidelines, and policy reforms to improve equitable dermatologic care.

This clinical study on fibrosing alopecia in a pattern distribution among a Latin American population reports no new results but addresses this specific condition in its demographic context.

This review discusses forensic DNA phenotyping and its potential applications, particularly for human identification in Latin American populations, but notes challenges due to genetic diversity and reports no new results.

This study found that inhibiting neurosteroidogenesis affected GABA A receptor-mediated synaptic inhibition in immature rats but not in adults, suggesting age-dependent modulation of synaptic strength in the spinal dorsal horn.

This review discusses the diagnosis, treatment, and management of atopic dermatitis in developing countries and identifies significant unmet medical needs, particularly in access to care and effective treatments; it reports no clinical results.

This study created transgenic mouse models with the LMNA gene mutation common in Hutchinson-Gilford progeria syndrome, revealing skin and teeth abnormalities related to transgene expression levels.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

This study observed that applying a pulling force to hair follicles led to significant compression of nuclei in certain cell layers and distinct collagen changes at different follicle depths.

This study explored the effects of a common Hutchinson-Gilford progeria syndrome mutation in an inducible mouse model, revealing skin abnormalities similar to those in affected patients.

In this study, using a mouse model, researchers found that inducing senescence in hair follicle stem cells led to hair regeneration failure and sebaceous gland enlargement, akin to androgenetic alopecia features.

Paclitaxel chemotherapy causes premature aging and damage to hair follicles, potentially leading to permanent hair loss.

This review discusses Hutchinson-Gilford Progeria Syndrome, its symptomatology, and the progress in developing treatment strategies, emphasizing that while a cure remains elusive, advances in understanding the disease's molecular mechanisms show promise for future approaches.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

Taxane chemotherapy can cause permanent hair loss by damaging hair follicles and altering their DNA.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

The connective tissue around hair follicles changes structure throughout the hair cycle.

Aδ-LTMRs have complex synapses with glycine, while Aβ-LTMRs have simpler ones.

This study reports new cellular features and complex interaction systems in fiber differentiation, indicating more intricate cellular organization than previously recognized, including features like mast cells and primary cilia.

This case report describes a 22-year-old woman with a nevoid plaque termed localized follicular hamartoma, characterized by skin-colored papules and specific cellular and structural features.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This review discusses the unmet needs and barriers in managing alopecia areata in Latin America, highlighting access constraints and recommending coordinated efforts to improve patient outcomes with promising new treatments.

This study observed that the mechanical connection between hair follicles and connective tissue in human fetal scalp skin is weaker than in the corresponding skin components, reflecting dynamic processes in hair growth.

This review discusses genetic mutations associated with Hutchinson-Gilford progeria syndrome and reports no clinical results; the authors emphasize the importance of cardiovascular monitoring in management.
