This study demonstrates a method using intravital imaging to observe sensory hair-cell development and regeneration in zebrafish, which may facilitate assays for drug discovery related to aural function preservation.

This study identified a new subset of Ret-positive sensory neurons involved in itch perception, characterized by their unique expression profile and response to specific itch-inducing molecules.

This review reports that hair follicles are dynamic neuro-immuno-endocrine organs with intrinsic signaling pathways, which play a crucial role in hair disorders like alopecia. It highlights emerging regenerative approaches targeting these pathways for hair restoration.

This study identified that rose, thyme geraniol, palmarosa, and tolu balsam essential oils activate TRPV1, with citronellol and geraniol as newly recognized agonists.

EGFR signaling is essential for ear cell regeneration in both birds and mammals.

This study observed that after hair cell loss in the mouse cochlea, supporting cells were replaced by migrating non-specialised cells, with genetic background affecting the rate of tissue re-organization.

This study presents a two-photon imaging method to visualize low-threshold mechanoreceptor axon terminals in live mouse forepaw skin, enabling repeated high-resolution imaging to study sensory circuits during development and adulthood.

This study in male rats identified a unique type of mechanoreceptor, the club-like ending, which responds only to touch and not to self-motion during whisking, contrasting with other receptors that show mixed selectivity.

This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This study in neonatal chicks reported that intense sound exposure severely impaired auditory function, but function returned to near normal within 3 days, primarily due to non-hair-cell mechanisms.

In this study, researchers found that the glabrous skin of the rat forelimb contains sparse Meissner corpuscles and Merkel complexes, with more slowly adapting afferents in the palm and rapidly adapting afferents in the digit extremity.

This study found that lymph vessel morphology and density in airways differed based on location and type of epithelium, with the highest density in the ciliated epithelium of the nasal passages and site-specific patterns apparent in both fetal and adult specimens.

This study indicates that the OVOL1-OVOL2 axis may play a significant role in hair follicle differentiation and growth, potentially serving as therapeutic targets for hair disorders like alopecia and in the tumorigenesis of pilomatricoma.

This review discusses the molecular mechanisms involved in hair follicle development and regeneration, highlighting findings from mouse genetic studies, and reports no new experimental results.

Genes controlling hair growth and immune response are disrupted in male pattern baldness.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study found that knocking out the Hars2 gene in mouse cochlear hair cells led to mitochondrial dysfunction and ROS stress, resulting in progressive hearing loss and differential effects on inner and outer hair cells.

Fungi-produced compounds can change plant root growth.

This study found that the contribution of the hair follicle pathway to skin permeation of chemicals can be predicted using lipophilicity, with hydrophilic chemicals showing greater permeation reduction from hair follicle plugging than lipophilic ones.

Hair follicles in the nose may need better cleaning to prevent Staphylococcus aureus infections.

This study found that distinct neurons in the nucleus accumbens lateral shell regulate scratching behavior differently; D1R neurons promote scratching while D2R neurons help stop it, with elevated dopamine levels during chronic itch potentially enhancing persistent scratching.

In this study, researchers found that simple hair clipping in mice induced dynamic plasticity and axogenesis in skin sensory axons, linked to follicular activation and HGF signaling.

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study found that a combination of four transcription factors can transform mouse fibroblasts into cells resembling inner ear hair cells, potentially aiding research into hearing loss treatments.

This study suggests that supporting cells are the origin of regenerated hair cells in the avian basilar papilla, with epidermal growth factor as a potential trigger, and indicates a possibility of hair cell regeneration in mammalian vestibular epithelia.

This study, involving an international panel of 16 psychodermatology experts, proposed a new classification system for psychodermatology disorders that aims to unify previous classifications and improve their management by systematizing disorders into two main categories: primary mental health disorders and primary skin disorders.

Aptamers can improve wound healing and promote hair growth.

This study found that OVOL1-regulated genes, particularly Fst and SFRP1, significantly affect the hair-inducing capacity of neonatal mouse dermal cells.

This study found that in mice, competition for hair follicles guides the organization of follicle-innervating LTMR neurons during early development, with different neuronal subtypes showing varying adaptive responses to increased neuron populations.
