This review highlights the ongoing challenges and advancements in developing precise and early intervention strategies for autoimmune diseases and emphasizes the need for more personalized and disease-specific therapies.

This study highlights the potential of forensic DNA phenotyping using Next Generation Sequencing to predict eye, hair, and skin color, aiding criminal investigations, though adoption faces challenges due to incomplete genetic understanding and ethical, social, and legal concerns.

Basal cell carcinoma shows keratin patterns similar to undifferentiated hair follicle cells.

A rare skin condition causes red and dark patches on the face and limbs.

This case report highlights the significance of alopecia totalis and knuckle pad hyperpigmentation as early indicators of azathioprine-induced myelosuppression and pancytopenia.

Immune cells boost stem cell activity in hairy moles, causing more hair growth.

This study reports that immunologically inert and skewed immune cell populations in developing human skin may contribute to wound healing and structural changes during skin development.

In a proof-of-concept study at Xiangya Hospital, the researchers observed that combining tofacitinib with low-dose interleukin-2 helped maintain remission in refractory alopecia areata patients, with three out of four maintaining complete remission for 11–20 months post-treatment and no adverse events reported.

This case report presents a rare manifestation of secondary cutaneous B-cell lymphoma as erythematous macules coalescing into reticular patches on the scalp and forehead.

This study found that inducing hair follicles into the anagen-onset stage in mice enhances the immune response to a topically applied DNA vaccine against anthrax.

This case report describes the development of halo naevi, vitiligo, and diffuse alopecia areata in a 33-year-old woman undergoing tocilizumab therapy, suggesting a link between these conditions and cellular and humoral immune factors.

This case report describes the first instance of eosinophilic folliculitis of the scalp occurring during nivolumab therapy, which responded partially to topical steroids and cream but did not require stopping the treatment.

Bimekizumab quickly improves psoriasis symptoms and skin at the molecular level.

This case study suggests that autoimmunity involving cytotoxic CD8+ T cells may link alopecia areata and human T-cell lymphotropic virus-1-associated myelopathy in adult T-cell leukemia/lymphoma patients.

In this scoping review and meta-analysis, researchers found that patients with alopecia areata exhibit complex chemokine profiles, with elevated levels of Th1, Th2, and other immune pathway-associated chemokines, suggesting the potential for broad immunomodulatory strategies to address the disease's immune dysregulation.

This study found that keratin 19 and nuclear galectin-1 binding can transiently express in interfollicular epidermal cells after adhesion, suggesting keratin 19 should not be solely used as a stem cell activity marker.

This study found that in alopecia areata, treatment with the oral JAK-inhibitor tofacitinib decreased clonally expanded CD8⁺ T cells in the scalp, but many expanded clones did not completely disappear, potentially leading to relapse after stopping treatment.

In this case report, a 17-year-old with systemic lupus erythematosus showed improvement in erythema multiforme-like lesions after treatment with methylprednisolone.

In this study, the elimination of NG2+ hair follicle stem cells during the anagen phase was associated with an aggravated sensitization phase of allergic contact dermatitis, suggesting their immunosuppressive role.

This case report describes a 69-year-old man diagnosed with folliculotropic mycosis fungoides after initially being treated for folliculitis, highlighting emerging skin lesions despite subsequent photochemotherapy and acitretin treatment.

This study found that active telethermography could help identify cancerization fields in individuals with actinic keratosis by detecting hyperthermic halos around tumors, which showed significant changes after treatment with a photolyase device.

This report details a case of a 43-year-old woman developing yellowish papular eruptions alongside typical acneiform skin reactions on her cheeks and chest following a switch from cetuximab to panitumumab treatment.

This study found that ITGA6-positive dermal sheath cup cells, identified by their superior migratory activity, may enhance cell-based therapy for male and female pattern hair loss by promoting cell migration into hair follicles.

This review discusses common cutaneous reactions to targeted cancer drugs such as tyrosine kinase inhibitors and reports no new clinical results.

This study highlights the need for further research on dysregulated immune and fibrotic pathways in morphea to better understand its pathogenesis and develop new biomarkers and therapies.

This study attempts to classify histomorphologic reactions to drugs to aid in diagnosing drug eruptions, which are common in hospitalized patients but lack specific diagnostic features.

This study reports that treatment with X-rays or procarbazine induced dose-dependent mutations in melanocytes in mouse hair follicles, showing similar mutation rates to previous methods.

This study reports that some human cell surface HLA-I molecules (including HLA-B27) can appear without their usual peptide component, potentially altering immune interactions, influencing arthritis development in specific mice models, and exhibiting upregulation in certain cancer cells.

This review explores the autoimmune hypothesis of alopecia areata and the possible genetic and melanogenesis-associated autoantigens, but reports no new clinical findings.

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.
