Hair follicle samples effectively show how well the drug MK-0752 targets and engages with the Notch pathway.

In this study, FITC-labeled BSA nanocarriers delivered a model drug deeper into porcine ear skin hair follicles than the carriers themselves, as shown by confocal microscopy.

Wnt signaling affects the development and growth of Langerhans cells in mice.

This study examined dermoscopic features in African-American women with different types of alopecia and found that a perifollicular pink blush, potentially indicating inflammation, was common, particularly resolved with anti-inflammatory treatment, suggesting dermoscopy could aid in management.

This study found that intracellular Toll-like receptors were significantly up-regulated in peripheral blood mononuclear cells of alopecia areata patients, suggesting a potential role in inflammatory signaling and pathogenesis.

This study found that FLCN deficiency in mice muscles led to increased mitochondrial biogenesis and a metabolic shift towards oxidative phosphorylation, with a similar advantage observed in FLCN-null kidney cancer cells.

This study demonstrated the development of high-density protein microarrays allowing for antibody binding characterization and serum profiling from patients with autoimmune diseases, suggesting potential for diagnostic marker discovery.

This case series found that patients with the NUDT15 415C>T variant experienced severe azathioprine toxicity, suggesting genotype-based dosing could reduce adverse effects.

This study developed the mTurquoise2-Col4a1 mouse model and used fluorescent tagging of collagen IV to offer new insights into basement membrane dynamics during hair follicle budding, revealing that basement membranes are flexible and stable structures in developing skin tissue.

This study found that Epstein-Barr virus infection upregulated a truncated variant of human basic hair keratin 1 (hHb1-ΔN) in gastric carcinoma cell lines, suggesting a possible link to carcinoma differentiation.

This study found that the genes FCER1A and RGS1 are promising biomarkers for diagnosing systemic lupus erythematosus, with FCER1A downregulated and RGS1 upregulated in patients.

This study found that ERBB2 mutations and amplifications are likely key drivers of extramammary Paget disease, suggesting potential for targeted therapies and cancer immunotherapy due to the moderately high mutational load observed.

This study found that overexpressing the 14-3-3σ protein in transgenic mice reduced keratinocyte proliferation and migration, leading to thinner epidermis and fewer hair follicles due to IGF-1 pathway inhibition.

This study suggests an association between DNA methylation changes in hair follicles and inherited color dilution in Rex rabbits, contributing to a deeper understanding of epigenetic influences on rabbit pigmentation.

In this study, deleting the Igf1 receptor in specific skin cells of mice affected hair follicle cycling but not overall skin health, suggesting Igf1r's role in hair cycle regulation through Bmp-4 activation.

This study suggests that cutaneous lymphadenoma is a distinct benign lymphoepithelial tumor characterized by androgen receptor expression, hair follicle stem cell markers, and common EGFR gene mutations.

This study developed an Asian human sebocyte cell line from breast skin tissue that can be used for sebaceous gland biology investigations, showing that Y27632 may promote cell growth through EGFR-CRAF-MEK-ERK and AKT pathways.

In this study, high levels of the protein Flii in mice were associated with worsened symptoms and inflammation in ulcerative colitis, suggesting Flii may inhibit mucosal healing.

This study found that Hoxc13-/- rabbits exhibit complete hair loss on the head and dorsum, providing a potential model for understanding human ECTD-9 and related dermatological conditions.

In ex vivo organ culture of human scalp hair follicles, this study found that IL-9 signaling inhibits hair growth, reduces progenitor cell generation, and disrupts immune privilege.

This study developed new immortalized keratinocyte cell lines lacking COL7A1 using CRISPR/Cas9 technology, providing a valuable model to explore the biology and treatment options for recessive dystrophic epidermolysis bullosa.

This review discusses the role of the CXXC5 protein as a transcription factor and signaling coordinator, noting its involvement in embryonic development, tissue homeostasis, and diseases such as tumorigenesis, but reports no new experimental findings.

This study suggests that TIP39 and its receptor PTH2R, identified in human epidermis, may play a role in keratinocyte function and influence skin differentiation.

In this study, one type of commercial culture medium supported expression of stem cell markers in hair follicle epithelial stem cells, but their differentiation potential and hair follicle-inducing ability declined over time.

Brepocitinib improves cicatricial alopecia and reduces key immune markers.

This study describes a case of cyclic thrombocytopenia where a novel MPL gene mutation may contribute to the disease, with gene expression changes in platelet and neutrophil genes preceding platelet count fluctuations.

This source reports that trastuzumab deruxtecan improves outcomes in HER2-positive and HER2-low metastatic breast cancer, emphasizing the need for careful adverse event monitoring, particularly for interstitial lung disease, and managing emetic risk to maximize benefits.

In this study using the C3H/HeJ mouse model of alopecia areata, researchers found that hyperexpanded CD8⁺ T cell clones were sufficient to initiate disease, establishing a causal link between T cell clonality and pathogenicity.

The researchers reported that the ethyl ester group in YH239-EE may enhance its ability to induce cell death, making the (+) enantiomer a potentially promising therapy for breast cancer reflected in MCF7 cell studies.

This study developed a novel treatment method using carbon dots from Cinnamomum burmannii leaves, which improved hair regeneration and thickness in an AGA mouse model by promoting cell proliferation, angiogenesis, and reducing inflammation through multiple signaling pathways.
