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.

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.

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

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.

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.

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.

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.

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.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This article describes a rare case of alopecia with both scarring and non-scarring features, combining histologic signs of central centrifugal cicatricial alopecia with select immunologic features of alopecia areata.

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.

In this study, Flii overexpression in mice enhanced fingertip regeneration and nail formation after both distal and proximal amputations, suggesting a role in digit and hair follicle regeneration possibly involving Wnt signaling.

This review discusses the biological characteristics and regulatory mechanisms of type 3 innate lymphoid cells and their roles in mucosal immune homeostasis, with no new experimental results reported.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

This study found that Phaeodactylum tricornutum extract enhanced hair follicle cell proliferation, indicated by increased keratin and ERK1/2 signaling, suggesting its potential for hair care applications.

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.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

Scalp tourniquets did not significantly prevent hair loss from chemotherapy.

This study in Kitui County, Kenya, identified histopathological lesions due to Cordylobia anthropophaga infestations in dogs, including parasitic granulomas and eosinophilic lymphadenitis, leading to severe health effects such as emaciation and potential death.

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 scoping review reports that while empirical evidence suggests an overlap between Long/Post Covid-19 syndrome, chronic fatigue syndrome, and fibromyalgia, the underlying molecular mechanisms remain unclear, highlighting the need for standardized definitions and rigorous methodologies in Long Covid research.

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 study found that microbial transformation of dihydrotestosterone with two types of fungi produced eight metabolites, among which metabolites 5–7 were significant inhibitors of butyrylcholinesterase, suggesting potential in Alzheimer's disease management.

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.
