This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This article discusses inflammatory perifollicular fibrosis and alopecia but provides no new research findings.

In this study, a single deslorelin acetate implant led to substantial and sustained hair regrowth in two sexually intact male keeshonden with hair cycle arrest.

Low-level laser therapy may help regrow hair in dogs with non-inflammatory hair loss.

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 study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.

This study found that foot shock stress prolonged the telogen stage and delayed anagen induction in the hair cycle of non-depilated mice, potentially through stress-induced actions of substance P.

This study found that hair regrowth in Pomeranians with hair cycle arrest treated with melatonin was not associated with a change in oestrogen receptor-α staining.

This study found that irregular menstrual cycles in Brazilian adolescents were significantly associated with a higher occurrence of metabolic syndrome and polycystic ovary syndrome indicators.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

In this study, XMU-MP-1 unexpectedly reduced cell proliferation and altered cell cycle progression in a model human hair follicle, possibly due to off-target kinase inhibition.

This study developed a mathematical model to simulate immune interactions and hair cycle dynamics in alopecia areata, identifying influential factors affecting hair growth and offering insights into potential treatment strategies by targeting immune dysregulation.

In this study, researchers developed a mathematical model to explore how immune system dynamics affect hair follicle behavior in alopecia areata, identifying key parameters influencing disease progression and suggesting potential treatment strategies targeting immune dysregulation.

This study identified shared gene expression changes and immune cell infiltration patterns that may contribute to hair loss in alopecia areata and cutaneous lupus erythematosus, but also highlighted factors that might preserve hair in psoriasis patients.

Anti-IL-1 treatments might help with certain types of hair loss in people with high inflammation.

This case report describes a rare instance of tinea capitis in a 19-year-old male, initially misdiagnosed as dissecting cellulitis, highlighting the need for accurate diagnosis to prevent scarring alopecia.

In this study, 17β-estradiol increased VEGF production in differentiated THP-1 cells, while dihydrotestosterone counteracted this effect by modulating adenylate cyclase activity.

In this study, the pharmacological action of dobutamine on rabbit retinae was found to be distinct from that of other dopamine analogs like apomorphine and N-methyl-dopamine.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

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 cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This article discusses the hair cycle of mice and its relevance in studying experimental carcinogenesis sequences, but it reports no new research findings.

This study found that maternal PPARγ is essential for preventing the production of inflammatory lipids in mouse milk, which can otherwise cause inflammation, alopecia, and growth retardation in nursing pups.

In this study, bovine testes hyaluronidase accelerated wound healing in vitro and in vivo by enhancing cellular proliferation, reepithelialization, and modulating inflammation in rat models.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.
