This review summarizes recent findings on how the dysregulated PI3K/Akt/mTOR pathway contributes to immune-mediated inflammatory skin disorders and discusses the potential of natural products, synthetic compounds, and biologic agents in their treatment. However, it emphasizes the need for further research to develop effective therapies.

This study found that loss of epidermal PPARγ in mice altered the expression of many genes related to skin inflammation, keratinization, and sebaceous gland function, indicating its key role in maintaining skin homeostasis.

This study reviews various skin models and methodologies used to assess the follicular penetration of nanoparticle-based drugs, highlighting inconsistencies that complicate comparisons and aims to establish more uniform protocols for clearer study outcomes.

This study developed finasteride-containing granules using a method that improved follicular targeting for androgenic alopecia and reported potential for easy industrial production.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

This study found that hair care products containing fermented papaya, fermented mangosteen, and caffeine significantly inhibited hair loss, increased hair density and thickness, and improved hair follicle structure in individuals with androgenic or diffuse alopecia over three months compared to placebo and caffeine controls.

This review summarizes the potential of exosome-based therapies as a promising treatment for androgenetic alopecia, emphasizing their role in modulating key signaling pathways, but highlights the need for further evidence to confirm their efficacy and safety.

This study integrated single-cell RNA-seq data from four previous studies to create a comprehensive human corneal cell state meta-atlas, revealing novel marker genes, rare cell states, and distinct transcription factors, and offering a tool to enhance future cornea research.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

This review discusses the metabolic and physiological mechanisms that maintain hematopoietic stem cell function, particularly focusing on oxygen and energy homeostasis, but it reports no new experimental results.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This review discusses the potential benefits of myo-inositol supplementation for insulin resistance-related disorders and diabetic complications, but reports no new clinical results.

This review discusses the role of TGF-β signaling in stem cell recruitment and tissue regeneration, indicating that abnormalities in TGF-β activation contribute to various major diseases and suggesting avenues for therapeutic intervention.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

This review discusses the regulation of involucrin gene expression, focusing on transcription factors and signaling pathways, and reports no new experimental findings.

This study identified that Eda-A1 unexpectedly induces placode inhibitors dkk4 and lrp4, indicating the importance of tightly regulated signaling for proper ectodermal organ development.

This study found that postnatal treatment with recombinant EDA normalized adult teeth, improved sweating, and restored normal lacrimation in dogs with XLHED, suggesting its potential as a treatment for the condition.

This study found that long-term minoxidil treatment, despite improving hemodynamics and left ventricular function, was associated with more frequent clinical events and a poorer clinical course in patients with chronic left ventricular failure.

This review finds that vigorous aerobic exercise and resistance training may improve insulin sensitivity and androgen levels in women with PCOS, though more research is needed for definitive conclusions.

This study found that overexpression of the enzyme SSAT in a mouse model significantly reduced prostate tumor size and progression, suggesting it could be a promising strategy against prostate cancer.

This case report describes an HIV-infected patient on HAART who developed autoimmune diseases, including alopecia universalis and Graves' disease, associated with immune restoration after CD4 cell count increases.

This study discovered that TREM2 macrophages influenced by squalene play a role in acne's development by hindering the killing of Cutibacterium acnes, helping explain why benzoyl peroxide is effective in treatment.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

This study found that after injury, the bone marrow microenvironment's increased Wnt10b expression supports hematopoietic stem cell regeneration by enhancing Wnt signaling, revealing a vital interaction during recovery.

Type I keratin genes are closely linked to the rex locus on mouse chromosome 11, affecting hair development.

This study found that although progerin expression in mouse skin causes significant nuclear shape changes in keratinocytes, it does not result in alopecia or common skin abnormalities seen in human Hutchinson–Gilford progeria syndrome.

This study reports that in systemic sclerosis, CD34+ dermal fibroblasts transition to CD34−, podoplanin+, and CD90+ fibroblasts across the dermis, suggesting a role in unchecked fibrosis.

In this study, researchers found that human fingerprint ridges are formed through a modified hair follicle developmental process and spatial patterns influenced by specific signaling pathways.
