This study found that using isotretinoin and acitretin was not linked to a higher risk or severity of COVID-19 in patients undergoing systemic retinoid therapy.

This study suggests that hydroxypinacolone retinoate (HPR) may be an effective alternative to tretinoin for anti-aging skin treatments, offering similar collagen production benefits without increased skin irritation.

This study found that the synthetic retinoid EC23 effectively induces keratinocyte hyperproliferation and enhances hair growth in mice, showing more potency than all-trans retinoic acid.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study describes GPRC5D's unique expression pattern in tissues that produce hard keratin, with retinoic acid inducing its expression in hair bulb cells and affecting keratin gene regulation.

This study found that RAR-gamma 1 mRNA is present in multiple skin layers and structures, suggesting a role in maintaining and differentiating normal epidermis and skin appendages.

This study reports that in mice, retinoic acid mediates communication between hair follicle and melanocyte stem cells by influencing differentiation in their shared niche during hair regeneration.

This review discusses the off-label uses of retinoids in dermatology, focusing on oral isotretinoin and acitretin, and reports no new clinical results.

Ch55 may help reduce skin scarring and fibrosis.

This study discusses the potential of topical retinoids, vitamin A derivatives, to improve treatment outcomes for androgenetic alopecia by promoting hair growth through extending the anagen phase and stimulating follicular activity, offering a promising approach when combined with existing therapies.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

This study found that DGAT1 functions as a key enzyme in murine skin to regulate retinoic acid levels and prevent retinoid toxicity, impacting hair cycle and sensitivity to retinol.

In this study, a new formulation of all-trans retinoic acid bound to polyvinyl alcohol showed reduced skin inflammation and sustained drug release for up to six days compared to free ATRA in vitro and in vivo.

This study found that all-trans retinoic acid (ATRA) negatively affects hair growth by reducing goat dermal papilla cell viability and growth factor expression.

This review explores the psychological and medical implications of hair loss, suggesting it may indicate a serious systemic disorder, but it does not present new research findings.

Topical retinoids effectively improve photodamaged skin.

This review discusses the various uses of retinoids, derived from vitamin A, in cosmetic and dermatological treatments for conditions like acne, psoriasis, and skin aging. The authors emphasize retinoids' limited use due to their susceptibility to degradation and safety concerns, particularly with retinoic acid.

This study suggests that vitamin A influences the immune response and hair cycle, affecting the progression of alopecia areata in mouse models.

In this study, researchers found that activating RORA in hair follicle stem cells reduced the expression of cytoskeleton-related genes, affecting cell migration and adhesion, which may aid in understanding hair follicle development and potentially inform alopecia treatments.

This study found that melatonin may enhance hair follicle stem cell viability by downregulating the nuclear receptor RORA, which otherwise inhibits cell proliferation and promotes apoptosis.

In this study, researchers found that RORA directly regulates the expression of the Bnip3 gene, which is crucial for hair follicle stem cell health, using rat HFSCs as a model. They propose that targeting RORA could modulate HFSC status.

This report describes cases of transient thyrotoxicosis potentially linked to oral retinoid treatment, suggesting a possible mechanism involving increased iodine uptake by thyroid cells.

This study found that 2MbisP increases epidermal thickening more rapidly than atRA in rhino mice, while both compounds similarly reduce utricle size.

This review suggests that a dual treatment approach using Nourella® cream with nano-encapsulated Retilex-A® and per-oral Vercilex® tablets may effectively improve skin thickness, elasticity, and overall rejuvenation in aging skin, as shown in interventional studies.

This letter to the editor discusses an observed case of hair repigmentation linked with etretinate therapy but reports no new research findings.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.

This article reviews the therapeutic use of interferons and other cytokines in various viral, tumorous, and inflammatory diseases, discussing their biological effects and potential future applications without presenting new experimental results.

This review examines various immunomodulatory therapies for cutaneous lymphoma and notes that they are most effective in the disease's early stages.

This article discusses the advances in understanding wound-induced hair follicle neogenesis (WIHN) and highlights the roles of specific signaling pathways and cellular plasticity, noting no clinical results but suggesting potential areas for further research.
