October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” 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.
October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.
This article explores how natural and man-made factors shape architecture and environments for human activity in emergency situations, focusing on the unique conditions of the Republic of Kazakhstan. Results are not reported.
This article explores how natural and man-made factors shape architecture and environments in emergency situations, focusing on principles relevant to Kazakhstan's specific conditions. Results are not reported.
September 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.
March 2023 in “Scientific reports” This study presents evidence that hair matrix progenitors and the enzyme Stearoyl CoA Desaturase 1 may play a role in maintaining the dermal papilla niche via autocrine Wnt and paracrine Hedgehog signaling in mice.
December 2022 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.
June 2021 in “Research Square (Research Square)” This article reviews current research on epidermal stem cells and differentiation, presenting models of basal layer composition, but reports no new experimental findings.
April 2020 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, researchers found that in growing skin tissue, epidermal wound healing occurs at the expense of normal skin development, as it impairs hair follicle growth and does not activate tissue morphogenesis genes.
November 2018 in “International Journal of Research in Dermatology” This study reported a 15% prevalence of tinea capitis among primary school children in Hyderabad, with various dermatophyte species identified as causative agents.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that electrical epilation in organ-cultured human scalp skin perturbs hair follicles by causing inflammation, impairing melanin production, and possibly inhibiting post-epilation hair re-growth.
April 2018 in “Journal of Investigative Dermatology” This article proposes a new classification system for cutaneous adnexal cysts based on their origin in the folliculo-sebaceous unit and sweat glands, aiming to clarify their categorization and origins.
April 2018 in “Journal of Investigative Dermatology” This study identified the osteopontin-derived peptide, FOL-005, as a potential inhibitor of unwanted human hair growth by promoting catagen development without reducing stem cell numbers or showing toxicity.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study observed that in an ex vivo setting, 17β-estradiol increased CB1 expression in human hair follicles, suggesting possible sensitivity to endocannabinoids and a potential mechanism for hair therapy.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” The authors concluded that Lrig1-positive stem cells are essential for sebaceous gland formation in mice, as their ablation led to temporary sebaceous gland disappearance without affecting hair growth.
January 2018 in “Stem cell biology and regenerative medicine” This paper reviews the role of ATP-dependent chromatin remodeling complexes in epidermal homeostasis, hair regeneration, and skin repair, noting contributions to 3D-genomic organization and suppression of UV-induced hyper-proliferation, without presenting new results.
July 2016 in “American Journal of Dermatopathology” The meeting showcased rare skin disease cases, highlighting the need for accurate diagnosis and treatment.
