This study found that patients with alopecia areata exhibited increased CRHR1 expression on circulating monocytes compared to controls, suggesting that stress-related factors like CRH and CRHR1 may contribute to the development and progression of the condition, particularly in chronic cases and those with larger lesions.

This study found that SSEA-4 is a marker that distinguishes eccrine from apocrine ductal cells in human sweat glands, suggesting its potential use in diagnostic applications.

This review discusses the pathogenesis and challenges in treating primary cicatricial alopecia, highlighting the need to understand immune protection collapse in hair follicle stem cells; it reports no new clinical results.

In this study, nestin-expressing cells in the hair follicle bulge, marked by GFP in transgenic mice, were identified as progenitors of the hair follicle outer-root sheath.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This study found that nestin-driven GFP labels blood vessels originating from hair follicles in mice, which could be used to study early events in skin angiogenesis and for antiangiogenesis drug screening.

This review summarizes recent advancements in follicular targeting for drug delivery via hair follicles and calls for pilot studies in humans to explore potential clinical applications.

This review discusses biological sex differences in COVID-19 outcomes and reports no new clinical results; it identifies a need for studies to clarify how sex influences disease progression.

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 found that CD34 is necessary for TPA-induced activation of hair follicle stem cells and tumor formation in mice, with CD34 knockout mice showing delayed and reduced tumor development compared to wild-types.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

In a transgenic mouse model, this study found that overexpression of keratin 16 in skin keratinocytes led to hyperkeratosis and increased EGF receptor signaling, altering skin cell behavior and structure.

CD44 variant changes start alopecia areata, but don't maintain it.

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 discusses the role of Toll-like receptors in wound healing and highlights their potential therapeutic value but notes that their role in human wound healing and chronic wounds is not well understood.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This study found that multipotent, nestin-expressing stem cells from the upper part of hair follicles can proliferate significantly and differentiate into various cell types, showing potential for nerve and spinal cord repair.

This study found that lymphatic vessels in mice are important for hair follicle development and organization, as their depletion blocks hair growth.

This review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

This study observed that while X-ray radiation did not alter major hair keratin composition in mice, it decreased hair follicle stem cell markers and increased Krt5, suggesting potential as a radiation biomarker.

This study found that ancient and modern Chinese goats share close genetic ties, originating from the Fertile Crescent, with genetic divergence influenced by China's climatic divisions.

This review discusses the potential of combining low-dose IL-2 with islet antigens to enhance antigen-specific Treg function in type 1 diabetes, but reports no new clinical results.

This study found that using a non-invasive multielectrode array for gene electrotransfer in hairless guinea pigs increased gene expression in the epidermis significantly, with minimal skin changes observed.
