This review describes how the skin can form its own immune response through dermal tertiary lymphoid organs, which function independently of traditional lymph nodes, potentially offering new insights into skin health care and treatments.

This case report details a 12-year-old boy from rural south India diagnosed with syringolymphoid hyperplasia, which presented with alopecia and anhidrosis.

D-chiral biomaterial scaffolds enhance tissue and hair regeneration by activating the body's immune system.

This study observed that DMAP scaffolds in a full-thickness wound model promote dermal appendage regeneration by activating humoral immunity, specifically through B cell activation and antibody production, even when adaptive immune cells' infiltration is restricted.

This study reported that an injectable hydrogel microparticle vaccine platform enhanced antibody responses and protection against influenza in mice, outperforming the traditional adjuvant aluminum hydroxide.

This study found that oral administration of cedrol, a component of ginger, improved hair regeneration and reduced hair follicle damage in cyclophosphamide-induced alopecia areata in mice more effectively than external administration, by enhancing cytokine expression and modulating key signaling pathways.

PCFCL may have unrecognized subtypes and needs more research.

Researchers demonstrated that a new vaccine platform using antigen-loaded hydrogels enhanced humoral immune responses in mice, producing stronger antigen-specific antibody levels compared to the conventional adjuvant Alum, and offering promising protective capabilities against influenza virus.

In this case study, a 24-year-old woman with frontal alopecia resembling frontal fibrosing alopecia was ultimately diagnosed with primary cutaneous follicle center lymphoma, highlighting the critical role of biopsy in identifying atypical alopecia presentations.

This study reported that both primary and secondary cutaneous follicle center lymphomas can present with atypical scalp or forehead lesions, leading to potential misdiagnosis as other skin conditions.

This case report describes a patient with primary cutaneous follicle center lymphoma who developed an alopecic atrophic patch potentially due to pressure, following rituximab treatment.

This study found that a 3D Matrigel culture technique for dermal papilla cell spheroids can enhance hair follicle inductivity and induce hair-like fiber differentiation in vitro, even with high-passage cells.

This case report suggests that platelet-rich plasma and hair transplantation may trigger or worsen the progression of cutaneous pseudolymphoma to lymphoma, particularly in patients with a family history.

Scalp tourniquets did not significantly prevent hair loss from chemotherapy.

Testosterone and dihydrotestosterone affect hair growth, and new techniques like the folliculogram help study it, but fully understanding hair growth is still complex.

This study found that Activin B at 10 ng/mL may promote vibrissae follicle growth in mice by enhancing hair matrix cell proliferation and cell cycle progression via ERK signaling pathways.

This study found that ING5 knockout mice are prone to developing lymphomas and severe dermatitis, suggesting ING5 plays a role in tumor suppression and stem cell maintenance in vivo.

This case report describes a rare pedunculated follicular hamartoma on the nasal septum of a 77-year-old Japanese male, emphasizing its unique clinical and pathological features.

This review discusses the role of the hedgehog signaling pathway in hematological cancers and its potential as a therapeutic target; it reports no new clinical findings.

This letter details 11 cases of scalp pseudocyst treated primarily with intralesional triamcinolone, resulting in complete hair regrowth in eight patients and self-resolution in some instances.

Minoxidil can help grow hair and make hair follicles bigger, but it can also cause side effects.

The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.

In this study with stumptailed macaques, topical minoxidil successfully induced hair regrowth on bald scalps and prevented baldness on non-bald scalps, with no observed side effects over nearly three years.

This chapter reviews recent advances in 5α-reductase inhibitors for treating disorders mediated by dihydrotestosterone and reports no new clinical findings.

This article discusses the hypothalamus-pituitary-testis axis in androgen production and spermatogenesis but presents no new research findings.

This review discusses the role of fibroblast heterogeneity in kidney pathology, particularly their contribution to tertiary lymphoid tissue formation, and reports no new results.

This article reviews the effects of various medications on male fertility, noting that while commonly used drugs can mostly have reversible impacts, conclusive human evidence remains limited.

This study concluded that horizontal sections of scalp biopsy specimens provide more diagnostic information for male pattern androgenetic alopecia than vertical sections and can predict hair regrowth potential following topical minoxidil therapy.

This commentary reviews the controversial use of mesotherapy for androgenetic alopecia and emphasizes the need for documented evidence, without reporting new clinical results.

This article discusses follicular cell implantation as a potential solution for hair restoration limitations, but notes inconsistencies and challenges in human applications, reporting no new clinical results.
