This study suggests that higher PDCD4 expression may play a significant role in polycystic ovary syndrome pathogenesis through its association with obesity, insulin resistance, lipid metabolism disorders, and increased granulosa cell apoptosis.

This study suggests that PDCD4 regulates keratinocyte proliferation and contact inhibition, playing a role in epidermal homeostasis and wound healing.

This study found that variations in the genes PDCD4, miR-21, and miR-449b may significantly influence breast cancer progression, with higher PDCD4 serum levels linked to increased breastfeeding.

This study found that PDCD4 protein expression is reduced in various skin cancers compared to normal skin, suggesting its potential role in preventing or treating certain skin cancers.

MicroRNA-21 could help diagnose and treat skin fibrosis.

This study indicates that CD4 protein may have a functional role in basal cell-like keratinocytes through TCR/CD3-independent signaling, affecting their proliferation, differentiation, and migration.

In this study, researchers found that CD4 is expressed on murine K5⁺ keratinocytes, and its expression is crucial for maintaining epidermal stem cell balance and wound repair capacity, particularly during aging.

ICL is a condition with low CD4+ T cells like AIDS but not caused by HIV, and normal CD4+ T cell counts may vary between men and women.

This study observed a wide range of mucocutaneous disorders among HIV-infected individuals in India, with a significant association between low CD4 cell counts and the presence of infectious and inflammatory skin conditions.

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.

This study reviewed changes in marketing practices of Australian clinics after a regulatory ban on direct-to-consumer advertising of stem cell products, finding improvements yet also limitations in addressing misleading claims and consumer safety.

This study found that digital droplet PCR (ddPCR) outperformed qPCR in detecting replication competent lentivirus in CAR-T products by offering better sensitivity, specificity, and reproducibility, making it a reliable and rapid method for ensuring patient safety.

This study explored how Australian patients and their carers perceived autologous stem cell interventions, highlighting factors like illness experience and unrealistic expectations that influenced their decision-making in an unregulated market.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This study observed that PD-1+CXCR5-CD4+T peripheral helper cells are significantly elevated in patients with systemic lupus erythematosus and are correlated with disease activity indicators, suggesting their potential role in lupus pathogenesis.

Certain immune cells in atopic dermatitis skin could be targeted for treatment.

This study found that a high percentage of HIV-positive patients experienced mucocutaneous lesions, with conditions like oral candidiasis and furuncle being significantly associated with lower CD4 cell counts.

This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This review explores how adipose-derived stem cells contribute to skin homeostasis and highlights recent advances in their clinical applications in dermatology, but it reports no new clinical results.

This study found that quiescence in hair follicle stem cells acts as a tumor suppression mechanism for cutaneous squamous cell carcinoma, with Pten activity necessary to maintain this state.

This review discusses the role of miRNA/mRNA regulatory networks in skin development, epidermal homeostasis, and tissue remodeling, and suggests potential for miRNA-based therapies in treating skin conditions, but reports no new clinical results.

This study found that WNT10A is significantly upregulated in human esophageal squamous cell carcinoma and is associated with enhanced tumor cell migration, invasion, and poor survival.

This article reviews the role of microRNAs as epigenetic modulators in dermatology but reports no new clinical findings.

This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

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.

In this study, transcriptome analysis identified 68 differentially expressed miRNAs in human dermal papilla cells treated with hydrogen peroxide, suggesting they play a significant role in growth arrest and apoptosis.

This study found that β-catenin is essential for hair follicle stem cell proliferation and may regulate this process through the PI3K/Akt pathway, suggesting its potential as a therapeutic target.

This review discusses "follicular hypoglycania" as a potential pathology in hair growth disorders and reports that proteoglycan replacement therapy may improve hair loss treatments, though it presents no new clinical trial results.

This study suggests that the rs2075876 variant in the AIRE gene may significantly increase susceptibility to alopecia areata in the examined male population.
