This study found that PGRP-S expression in mouse epidermis is specific to certain hair follicle epithelia, depending on the skin region, and can be transiently induced in flank skin hair follicle epithelium after exposure to Staphylococcus aureus, suggesting a role in environmental surveillance.

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 review article examines recent studies on the role of diverse immune cells in forming an active niche for hair follicles, offering new insights into hair growth and related diseases.

This review explores the significant impacts of hormonal changes within normal physiological ranges and suggests examining low-dose effects from chemicals disrupting hormonal activity; it presents no new clinical results.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This study identified that pediatric transplant recipients experience specific skin changes related to medication use, with unique conditions like ichthyosiform xerosis in kidney recipients and skin scaling with pellagroid appearance in bone marrow recipients.

This study found that a key gene signature, including FGF11, highlights the immunologic nature of keloid lesions, distinguishing them from normal fibroblasts and scars.

This review found that adding immune checkpoint inhibitors to cancer treatment regimens likely increases the incidence of specific drug-related skin toxicities in adult Asian patients, highlighting the need for careful monitoring and management strategies.

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 identified somatostatin as a potential secretory factor contributing to the immune privilege of human hair follicles.

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 review summarizes the clinical, trichoscopic, and histopathological features of alopecia types associated with cutaneous and systemic lupus erythematosus and explores their links to disease activity, but it reports no new clinical results.

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 review describes advanced drug delivery systems for dithranol aimed at overcoming stability issues and skin irritation seen in conventional formulations, highlighting options like nanoparticles and liposomes for improved psoriasis treatment.

This study found that measuring specific steroid hormone levels can aid in diagnosing P450 oxidoreductase deficiency, a subtype of congenital adrenal hyperplasia, by distinguishing affected patients from healthy individuals.

This review discusses the dynamic behavior of immune cells in skin immune responses using intravital imaging in mice and reports no new clinical results.

This study found that the protein p63 requires morphogenetic signals to regulate gene expression effectively during skin cell differentiation, highlighting its complex role in therapeutic reprogramming for conditions like epidermolysis bullosa.

This study found that patients with autoimmune skin diseases showed a statistically significant occurrence of hearing disabilities, suggesting the need for audiological evaluations in these patients.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This study found that certain gene sets, including those involved in ligand-gated ion channel signaling and cell adhesion, are associated with Tourette syndrome, suggesting a potential neurobiological basis for the disorder.

This review classifies engineered nanomaterials by composition and application in biomedicine, highlighting diverse uses like regenerative medicine and potential occupational side effects, but reports no new clinical results.

This study found that glioblastoma cancer stem cells avoid immune suppression by downregulating TLR4, and restoring TLR4 signaling may reduce tumor growth and self-renewal.

This study found that while the combination of oral propranolol and intradermal injections in guinea pigs led to psoriasiform changes, it did not fully mimic psoriasis.

This review discusses the roles of adiponectin and bradykinin in skin homeostasis and pathologies, highlighting the need for further research into their therapeutic potential but reports no new clinical results.

This study found that pediatric HSCT recipients, especially those with chronic graft-versus-host disease, are at risk for developing various nonmalignant late cutaneous changes such as vitiligo, psoriasis, alopecia, and nail changes.

This study found that an imbalance of selenium in a C57BL/6 mouse model led to hair loss with color change and was linked with changes in hair follicle apoptosis markers.

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.

In this study, researchers highlighted the high global prevalence of immune-related skin diseases like dermatitis and psoriasis, noting that females are disproportionately affected, emphasizing the need for tailored public health strategies based on sex and region.

This review discusses recent research on the relationship between gut microflora and depression, highlighting the potential for new insights into the pathogenesis and treatment of major depressive disorder.
