This study reports that activating the bitter taste receptor TAS2R4 with rebaudioside A can inhibit hair growth in human scalp hair follicles by promoting catagen through TGF-β pathway activation.

In this study, the researchers observed that antiandrogen treatment with Cyproterone acetate led to atrophy of pilo-sebaceous units and may activate Langerhans cells, contributing to local inflammation.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This study found that infused mouse epidermal growth factor induced wool follicle involution through a quasi-physiological process similar to catagen and a separate pathological action, resulting in fleece 'break' or shedding.

In this study, autopsies of children who suffered fatal abuse revealed stress-associated markers like telogen effluvium and thymus involution, which may help pathologists identify chronic abuse cases.

This research observed that during the catagen phase, the inner root sheath of hair follicles becomes an early target, highlighting its potential role in maintaining hair follicle homeostasis.

This study suggests that the inner root sheath plays a significant role in maintaining hair follicle homeostasis during the catagen phase's early stages.

This study observed that topical prostaglandin treatments may protect against hair follicle injury during chemotherapy, as indicated by preserved eyelashes in patients using these treatments.

This review highlights morphological factors contributing to age-related alopecia and suggests further research to understand and potentially mitigate cellular aging processes affecting hair quality.

Finasteride negatively affects fish reproduction and gonadal development.

This review explores the complexity of the hair cycle and discusses the roles of various growth factors, androgens, and cytokines in regulating hair growth, yet reports no new results.

This review discusses two approaches to address aging: a tactical method to delay and slow age-related issues, and a strategic method aiming to eliminate aging altogether by targeting its root cause.

This paper reviews the classification and diagnostic approaches for different types of alopecia, emphasizing the importance of early etiological diagnosis to prevent irreversible hair follicle damage in scarring forms.

This study found that IL18 signaling plays a crucial role in the homing and retention of mature regulatory T cells in the mouse thymus, primarily by upregulating the chemokine receptor CCR6.

Some moles can disappear naturally, maintenance therapy for Stage 1 mycosis fungoides may not be necessary, allergic skin reactions in children are rising, weekly methotrexate for psoriasis is more effective than daily, long-term finasteride use improves hair growth with few side effects, and petrolatum improves UV therapy for psoriasis.

TRPV1 helps regulate hair growth cycles.

This article discusses a potential link between adipocyte-myofibroblast transition and androgenetic alopecia, suggesting AMT may play a role in fibrosis associated with the condition but presents no new results.

This article discusses the presence of dirty dots as a normal trichoscopic finding in children, noting they are not observed in adults or other age groups, and reports no new results.

This case report describes a female Rottweiler with generalized congenital hypotrichosis, where most skin biopsies showed a complete absence of follicular development, marking only the second documented case of this genodermatosis in female dogs.

This study found that the petroleum ether extract of Citrullus colocynthis fruit and an isolated steroidal compound may reduce prostatic hyperplasia in rats induced by testosterone, suggesting potential use in managing androgen-dependent conditions.

This study found that stimulating toll-like receptor 5 via mucosal delivery of a flagellin-containing fusion protein effectively extended lifespan and enhanced healthspan in mice, including improved bone density and cognitive capacity.

This article discusses the clinical characteristics and treatment considerations for different types of alopecia, reporting no new research findings.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

In this study, the aim was to define the indications, diagnostics, and surgical techniques for eyebrow lift procedures, noting that the primary complication is a visible scar, especially concerning for individuals with a tendency for keloid formation.

This article discusses the treatment of androgenetic alopecia and alopecia areata with finasteride and minoxidil but reports no new clinical results.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.
