In this study, the researchers found that treatment with the JAK inhibitor tofacitinib in alopecia areata patients may reduce clonal CD8+ T cell expansions but does not eliminate them entirely, which could contribute to disease relapse.

In this study, a nanoparticle system codelivering diphenylcyclopropenone and rapamycin successfully induced immune tolerance and promoted hair regrowth in a mouse model of alopecia areata, offering a promising new therapeutic strategy for this autoimmune condition.

This study found that thymus transplantation in athymic mice resulted in T-cell-driven hair follicle depigmentation and loss, without multiorgan autoimmune disease, highlighting mechanisms of tissue-specific tolerance.

This study implicates EGFR as a critical regulator of immune privilege and stem cell quiescence in hair follicles, suggesting a link between EGFR inhibition and inflammation-driven hair loss during cancer therapy.

This study found that C3H mice with prior microbial exposure developed alopecia areata at a reduced rate and had fewer associated T cells compared to controls, suggesting that prior infections might attenuate autoimmune responses related to the disease.

This review discusses a "stochastic multi-hit model" to explain the onset, progression, and recurrence of vitiligo and other autoimmune skin diseases, emphasizing genetic and environmental influences, immune cell interactions, and unexplored mechanistic gaps.

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.

This study found that anagen stage protein homogenates and specific epitopes from melanogenesis proteins activated CD8 T cells, suggesting alopecia areata is an anagen-specific disease.

This study reports that a new mouse model with a CARD14 mutation successfully mimics key human PRP symptoms, and anti-IL-17A antibody significantly reduces these symptoms.

This study developed a 3D bioprinted skin model to mimic pemphigus vulgaris, providing a tool to study disease mechanisms and test targeted therapies by reproducing the architecture and pathogenic disruptions of native skin.

This study found that the development of Merkel cell carcinoma from hair follicles in mice can be driven by in vivo reprogramming with ATOH1 and relies on p53 loss for progression.

This study found that crosstalk between fibroblasts and endothelial cells significantly contributes to hypertrophic scar formation by enhancing fibroblast activity through cytokine secretion, with pathway analyses suggesting molecular targets for potential therapeutic interventions.

This research suggests that plucked hair follicles may serve as a reliable surrogate tissue for tumor biopsies in drug development, based on a mouse model linking hair and tumor pharmacodynamic responses.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This study reports that three synthesized PSMA-targeted radioimaging agents demonstrated high affinity and specific localization to prostate cancer tumors in a mouse model, highlighting their potential for cancer detection and monitoring.

In this study, researchers identified that upon tissue injury in a mouse model, epidermal cells at the wound edge convert to an embryonic-like state with SOX11 and SOX4 playing a central role in modulating epidermal development and cell migration genes.

In this study, finasteride was found to reduce costs associated with benign prostatic hyperplasia compared to watchful waiting and terazosin, especially in men with higher prostate-specific antigen levels.

In this study, researchers found that the compound BMS-470539 induced a senescence-like state in fibroblasts from systemic sclerosis patients, reducing fibrosis-associated markers in vitro and decreasing skin thickness in a mouse model of skin fibrosis, suggesting a novel therapeutic strategy for managing fibroblast-driven diseases.

This chapter reviews classic regeneration models in planarian worms and amphibian limbs, focusing on the role of stem cells, and reports no new experimental results.

This study found that blocking the chemokine CXCL12 in a testosterone-induced mouse model of androgenetic alopecia restored hair regeneration and reduced fibrosis and immune alterations.

This chapter reviews various in vitro and laboratory animal models for studying potential therapies for alopecia and reports no new results.

This study identified a crucial Gli2-Serpinh1 regulatory axis that regulates fibroblast state transitions during skin wound healing, shedding light on fibroblast heterogeneity and suggesting potential precision regenerative therapies.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.

This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This study demonstrates that Wnt signaling plays a crucial mechanoregulatory role in skin regeneration by influencing cellular responses to substrate rigidity, which promotes hair follicle regeneration in the wound-induced hair neogenesis model.

This study suggests that activating retinoic acid signalling can inhibit Wnt signalling and induce regression in certain skin tumors, providing potential therapeutic strategies for tumor regression.

This study identified peripheral myeloid cells as the earliest dysregulated immune cells in PINK1 KO mice with Parkinson’s-like symptoms following intestinal infections, suggesting that PINK1 regulates gut immune functions linked to early Parkinson’s disease mechanisms.

This study demonstrated that skin organoids derived from human stem cells can model cutaneous tuberculosis, revealing that fibrosis development in Mycobacterium tuberculosis-infected organoids is linked to the PI3K-AKT and AP1 pathways in fibroblasts, and suggesting the potential for antifibrotic treatment evaluation.
