Alopecia areata is caused by an immune response, and targeting immune cells might help treat it.

The researchers observed that overexpression of Wnt10b in a mouse model can induce hair follicle regeneration by switching follicles from the resting phase to the growth phase via the Wnt-β-catenin signaling pathway.

This study highlights cases of alopecia areata that developed during anti-TNF-α therapy, suggesting a potential link or increased frequency, particularly among individuals with a personal or family history of autoimmune diseases.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This study identifies NFAT5 as a crucial transcription factor necessary for triggering innate immune responses in the blood vessel lining that lead to atherosclerosis under hypertonic stress conditions.

Exosomes are crucial for protecting sensory hair cells in the inner ear.

In this study, young, nonobese PCOS patients showed significant insulin resistance, but no significant difference in endothelial function compared to healthy controls, suggesting other factors may influence endothelial health.

This study found that D'orenone blocks root hair growth by increasing PIN2 protein abundance, leading to reduced auxin concentration, but external auxin can reverse these effects.

This study found that progesterone reduces neuronal injury from tributyltin exposure in rat hippocampal slices through a mechanism dependent on allopregnanolone and GABAA receptors.

This review explores the potential impact of nutrition on immune-mediated inflammatory skin diseases and evaluates whether dietary changes could help in treatment planning, but it presents no new clinical outcomes.

This study found that enhanced expression of the Sonic hedgehog gene via an adenovirus vector accelerated hair regrowth in mice with chemotherapy-induced alopecia.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

In this study, cyclosporin effectively controlled cases of granulomatous folliculitis, furunculosis, sebaceous adenitis in cats, and alopecia areata in a dog, positioning it as a promising alternative to glucocorticoids in veterinary dermatology.

This study found that Rab5c is crucial for proper HSPC development in zebrafish embryos by regulating Notch and AKT signaling through endocytic trafficking, with both deficiency and overactivation leading to production defects.

This study suggests that UMPP activation is a key signaling pathway in differentiating primary and secondary hair follicles in cashmere goats.

This article discusses various types of primary cicatricial alopecias and reports no new clinical results; it emphasizes the importance of accurate diagnosis for effective management.

In this study, microneedles combined with finasteride nanostructured lipid carriers (FIN-NLC-MNs) were found to enhance skin penetration and specifically target hair follicles, promoting hair growth and gene regulation in androgenetic alopecia.

This study suggests that stress may worsen Tourette syndrome symptoms in mice by increasing allopregnanolone synthesis, with findings supporting finasteride as a potential treatment to manage symptom fluctuations.

This study found that BMP2 increased PTEN expression and induced autophagy, promoting hair follicle stem cell differentiation in both in vitro models and a mouse wound model.

This case report describes a patient with frontal fibrosing alopecia experiencing significant hair regrowth and reversal of cutaneous atrophy after treatment with the 5α-reductase inhibitor finasteride.

This study found that all-trans and 9-cis retinoic acids increase steroid sulfatase activity in HL60 cells through mechanisms involving RARα/RXR heterodimers and multiple signaling pathways.

Targeting THY1 can improve skin repair and healing.

This study found that PTEN regulates the number and genomic stability of hair follicle stem cells in the skin, with its deficiency leading to increased stem cell accumulation and senescence through interactions with BMAL1 and BMI-1.

In this study, overexpression of Wnt5a in mice was associated with the elongation of the telogen stage and inhibition of hair growth initiation, suggesting Wnt5a's role in maintaining hair follicle quiescence.

This study found that nanofibers combining a polydopamine coating and curcumin nanocrystals were effective in treating diabetic wounds infected with methicillin-resistant Staphylococcus aureus by providing sequential photothermal antibacterial action and promoting M2 macrophage polarization, which accelerated wound healing through enhanced angiogenesis and cell proliferation.

In this study, PEG and keratin scaffolds selectively influenced protein release rates based on charge and size, suggesting their potential for targeted delivery of protein therapeutics.

This review discusses the role of gut microbiota in autoimmune and immune-mediated dermatological conditions like lupus and psoriasis, but reports no new clinical results; the authors emphasize the need for further study into microbial signatures and treatments.

This study found that genetic activation of Nrf2 in keratinocytes accelerates wound repair by enhancing cell proliferation and re-epithelialization, suggesting potential use for Nrf2-activating compounds in individuals with impaired healing.
