This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

This study identified overexpression of certain immune-related genes and underexpression of genes in specific signaling pathways in premature androgenetic alopecia, suggesting potential new therapeutic targets.

In this study, adipose tissue secretome was shown to enhance oxidative stress resistance and promote cell proliferation in vitiligo cells, suggesting a potential natural treatment approach.

This chapter reviews hyperadrenocorticism in ferrets, covering its causes, symptoms, diagnosis, and treatment options, but reports no new research findings.

In this narrative review, researchers outlined the role of T cells in the autoimmune pathogenesis of alopecia areata and highlighted ongoing research into therapeutic pathways, beyond current JAK inhibitors, aimed at developing new treatments for the disease.

In this study, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

This study suggests that hair follicles may be the primary target in the onset of various skin diseases, potentially spreading to affect the surrounding epidermis.

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.

Natural products might help treat hair greying.

This review reports that hair follicles are dynamic neuro-immuno-endocrine organs with intrinsic signaling pathways, which play a crucial role in hair disorders like alopecia. It highlights emerging regenerative approaches targeting these pathways for hair restoration.

This study found that women with PCOS had significantly higher angiotensin converting enzyme activity and insulin resistance compared to controls, suggesting a correlation between these factors.

This article reviews potential mechanisms by which Finasteride might enhance mesenchymal stem cell viability and differentiation post-transplant, suggesting a supportive role in myocardial infarction therapy, yet reports no clinical results.

This study developed a precise and reliable UV spectrophotometric method for determining finasteride concentration in bulk and tablets, demonstrating strong linearity and accuracy.

This study developed and validated a UV spectrophotometric method for accurately measuring finasteride and tamsulosin in solutions and tablets, demonstrating good sensitivity and precision.

In this study, researchers observed that dysregulated innate lymphoid cells type 1, alongside CD8+ T cells, may contribute to the pathogenesis of alopecia areata by affecting hair follicle health.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This review discusses skin changes during pregnancy, highlighting both pregnancy-specific and common physiologic changes, but reports no new clinical findings.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This review identifies shared interferon gamma-driven immune pathways in vitiligo and alopecia areata, revealing potential targets for new treatments, but reports no clinical results.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

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

This study found that cucurbitacin I from bitter melon most effectively inhibited the growth of lung cancer cells and promoted hair cell growth in cell cultures.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

This review explores new theories, diagnostic tools, and management strategies for primary cicatricial alopecia but reports no new clinical findings.

This study indicates that targeting the PTH/PTHrP receptor may potentially stimulate hair growth, particularly for chemotherapy-induced alopecia, as observed in hairless and cyclophosphamide-treated mice.

This study found that dermatological manifestations in HIV-positive individuals, such as infectious and non-infectious dermatoses, were significantly associated with CD4 T cell count.

The researchers observed that normal murine hair follicles are direct targets for melatonin, with receptor expression varying throughout the hair cycle, suggesting melatonin's role in hair cycle control.

This article discusses the immune privilege in hair follicles and suggests that restoring its collapse might be an effective strategy for treating alopecia areata and cicatricial alopecia, but it reports no new clinical results.
