This literature review explores the role of biomarkers in personalized medicine for various dermatological conditions like Hidradenitis Suppurativa, Psoriasis, and Atopic Dermatitis, highlighting how they guide targeted therapies and the limitations of current markers in specificity, as reported by the authors.

This study found that the keratin expression in basal cell carcinoma resembles that of the pilosebaceous apparatus, with uniform presence of certain keratins in all cases.

In this study, single-cell sequencing revealed clonal expansions of CD4+ and CD8+ T cells in murine and human alopecia areata, supporting the development of predictive models for human disease.

This study found that histopathologic features of erythematous papulopustular eruption due to EGFR inhibitors vary with eruption severity and differ between cetuximab and erlotinib treatments.

This paper reviews signaling influences and niches of epidermal stem cells and compares various types, but does not present new experimental findings.

This study demonstrates that human epidermal stem cells can adapt to environmental temperature changes through mTOR signaling, and prolonged inhibition of mTORC1 supports stem cell maintenance, which may be vital for regenerative medicine.

This review explores how exosomes can be used therapeutically in autoimmune skin diseases, emphasizing that their properties like stability and biocompatibility make them promising for targeting immune signaling pathways involved in conditions such as inflammation and scleroderma.

In this study, researchers identified unique prenatal lymphocyte features in human fetal skin, including proliferative naive T cells and memory-like T cells, which may influence antigen and allergen responses in utero and infancy.

Targeted immunological therapies offer safer and more effective treatments for skin conditions like eczema and psoriasis.

In this case report, a patient experienced a recurrence of alopecia areata while undergoing etanercept treatment, suggesting the drug may not effectively prevent this condition's return.

This study found a specific T cell receptor that may be key in carbamazepine-induced Stevens-Johnson syndrome and toxic epidermal necrolysis, suggesting potential therapeutic targets.

This study suggests that novel diagnostic, preventive, and treatment approaches for autoimmune diseases like alopecia areata may be developed by identifying hub genes, and highlights the usefulness of machine learning and bioinformatics in finding new disease biomarkers.

This article reviews the complexities and challenges in classifying systemic lupus erythematosus and the problematic role of the anti-dsDNA antibody as a biomarker, without presenting new experimental findings.

This study found that DNA methylation and histone modification status were altered in peripheral blood mononuclear cells of patients with alopecia areata, suggesting these changes may contribute to the disease's pathological immune responses.

This study found that Merkel cell hyperplasia is specific to certain skin diseases and not related to general epidermal proliferation.

This study found that ectopic expression of the lymphoid-enhancer factor can induce K17 protein in the skin, suggesting a link between skin development and wound repair processes in mice.

In this study, researchers identified three pathogenic de novo genetic variants contributing to epidermolysis bullosa simplex in young children, highlighting the complexity of genetic influences and underscoring the need for early genetic screening for accurate diagnosis and effective management.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

Repetin is a protein involved in skin and hair development, binding calcium and compensating for other proteins when needed.

This study found that in mice, the epidermal microenvironment reverses the oncogenic effects of GNAQQ209L in melanocytes, inhibiting their survival and proliferation through paracrine signals.

This paper discusses the challenges of diagnosing drug eruptions, emphasizing the nonspecific patterns and unclear pathomechanisms, and calls for further research using new biologic drugs to understand these reactions better.

Certain CD8+ T cells attack hair follicles in alopecia areata, suggesting they could be targeted for treatment.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This study found that CRABP1, Nestin, and Ephrin B2 are expressed in both the tumor stroma and invasive front of skin adnexal tumors and basal cell carcinomas.

Certain immune cells in atopic dermatitis skin could be targeted for treatment.

This chapter describes procedures for isolating and purifying murine epithelial progenitors and assessing their ex vivo propagation capacity, but presents no new experimental results.

In this study, single-cell RNA sequencing of hair follicle populations from hidradenitis suppurativa patients identified three endotypes, suggesting distinct epithelial-immune interactions that may guide stratified therapeutic approaches.
