In this study, researchers found that female rats exhibited more pronounced panic-related escape behavior during hypoxia, particularly in the diestrus phase, and that low-dose fluoxetine reduced this behavior, suggesting its potential for managing panic disorder symptoms related to hormonal cycles in women.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This study provides evidence that human skin contains genes and enzymes necessary for producing serotonin and melatonin.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

In this study, a pH-responsive microneedle patch was developed, showing potential in rat models for treating spinal cord injuries by reducing inflammation, promoting nerve regeneration, and supporting neurogenesis, which contributed to improved motor and neurological recovery.

This study found that stimulation with certain neurotransmitters and hormones suggests the involvement of 5α-reduced neurosteroids in glial cell differentiation in rat C6 glioma cells.

This review discusses OCD spectrum disorders with dermatological symptoms, emphasizing their clinical features, neurobiology, and treatment options, while noting the need for more controlled studies.

This article explores how extrafollicular environments and stem cell configurations influence hair and feather regeneration but provides no new experimental results.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

This study suggests that melatonin may promote hair growth properties by activating the AKT/GSK3β/β-catenin signaling pathway in dermal papilla cells.

This study suggests that melatonin enhances the growth properties of DP cells by activating the AKT/GSK3β/β-catenin signaling pathway through its receptors in a 3D culture system.

This study found that melatonin may enhance hair growth properties in dermal papilla cells by activating the AKT/GSK3β/β-catenin signaling pathway through melatonin receptors.

Blocking CYP17A1 enzyme may help improve certain brain function issues related to dopamine.

This study found that systemic ovalbumin–aluminum sensitization followed by cutaneous challenge in mice induced thermal hyperalgesia, increased spinal cord gliosis, and sprouting of nociceptive fibers, along with elevated mast cell and nerve profile densities in the skin compared to controls.

This study found that minoxidil prevents long-term serotonergic toxicity induced by MDMA in rats, primarily by opening mitochondrial KATP channels and involving Akt and MAP kinases in its neuroprotective mechanism.

In this study, researchers found that the novel gene circCFAP20DC enhances the proliferation of goat follicular granulosa cells by activating the RB pathway, facilitating their progression from the G1 to S phase during follicular development.

This review discusses sex differences in the neuroendocrine response to stress, focusing primarily on rodent studies, and highlights open questions about the roles of gonadal hormones and sex chromosomes.

This study found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

This study highlights that ZNF750, a zinc-finger transcription factor, is crucial for epidermal differentiation and barrier formation in skin by activating genes involved in lipid processing and stratum corneum development, and links ZNF750 sequence variations to skin inflammatory diseases like psoriasis.

In this review, researchers explored the complex mechanisms behind chemotherapy-induced side effects like nausea, fatigue, and hair loss, and discussed potential strategies using natural agents to manage these toxicities, improving understanding for targeted adjunct therapies.

This review discusses the progress in identifying stem cells responsible for tissue regeneration and highlights technological advances in tracking their behavior, but reports no new clinical results.

This study demonstrated that skin organoids derived from human stem cells can model cutaneous tuberculosis, revealing that fibrosis development in Mycobacterium tuberculosis-infected organoids is linked to the PI3K-AKT and AP1 pathways in fibroblasts, and suggesting the potential for antifibrotic treatment evaluation.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but reports no new clinical results.

This study observed that serotonin signaling promoted hair shaft elongation and upregulated hair growth-related genes in dermal papilla cells, suggesting its potential role in advancing alopecia therapy.

This review reports that Dang Gui (Radix Angelica sinensis) possesses bidirectional immunoregulatory effects, enhancing immune cell proliferation and function, and may benefit immune-related diseases such as cancer and anemia. It also evaluates regulatory and safety aspects, aiming to guide future research and clinical use.

This study found that hair shaft miniaturization in aging and genetic hypotrichosis leads to hair follicle stem cell loss through mechanical compression and apoptosis mediated by the Piezo1 channel.

Allopregnanolone, a progesterone metabolite, helps reduce restraint effects on behavior.

In this study, researchers demonstrated that human hair follicle outer root sheath cells release ATP, serotonin, and histamine in response to mechanical stimulation, which subsequently activates surrounding sensory neurons.

This review discusses the impact of melatonin and its metabolites on skin aging, summarizing how they may serve as "aging neutralizers" through their anti-oxidative and anti-inflammatory properties, but reports no new clinical results.
