Histamine plays key roles in immune responses, stomach acid, and brain signals.
research Immunolocalization of a Histidine-Rich Epidermal Differentiation Protein in the Chicken Supports the Hypothesis of an Evolutionary Developmental Link Between the Embryonic Subperiderm and Feather Barbs and Barbules
In this study, researchers found that the EDMTFH protein is present in specific layers of the chicken embryo skin and feathers, suggesting its role in feather mechanics and development.
research Study on Histamine Related Enzyme Activities During Murine Hair Cycle
This study suggests that increased activity of the histamine synthesizing enzyme histidine decarboxylase may play a role in initiating the anagen phase of hair regrowth in mice.
research Histidine Decarboxylase Expression Influences the Neofolliculogenesis of Newborn Mouse Dermal Cells
This study found that histidine decarboxylase is crucial for the hair-inducing ability of newborn mouse dermal cells, with its expression significantly decreasing in the first few days after birth.
research Generalized Pruritus in Primary Sclerosing Cholangitis: Implications of Histamine Release by Lysophosphatidic Acid
This article discusses the role of lysophosphatidic acid-induced histamine release in generalized pruritus among patients with primary sclerosing cholangitis and reports no new clinical results.
research Influence of Glucocorticoids on Time-of-Day-Dependent Variation in Intradermal Reactivity to Histamine in Dogs
This study found that intradermal reactivity to histamine in dogs varies with time of day, and glucocorticoids may influence this variation.
research Application of Histamine Receptors H2R, H3R, and H4R, but Not H1R, in Dermatology
This review explores the roles of histamine receptors H2R, H3R, and H4R in treating various dermatoses but reports no new clinical outcomes.
research Effects of Botulinum Toxin Type A on Histamine-Induced Itch and Vasomotor Responses in Human Skin
This study found that subcutaneous administration of Botulinum toxin type A significantly reduced histamine-induced itch intensity and neurogenic inflammation in human skin compared to saline.
research Homeostatic Activation of Epidermal HSD11b1 Affects Skin Innervation and Non-Histaminergic Itch
This study observed that mice lacking epidermal HSD11b1 had increased non-histaminergic itch and changes in skin nerve fibers, potentially linked to higher TSLP expression.
research Advances in Histamine-Mediated Allergy Management: Expanding Perspectives on Cetirizine’s Therapeutic, Safety, and Toxicological Implications
This commentary highlights that cetirizine, a widely-used antihistamine, remains effective for various emerging allergic conditions, and new formulations and combination therapies may enhance its effectiveness while being generally well-tolerated.
research Experimental Evaluation of Ebastine, a Second-Generation Antihistamine, as a Supportive Medication for Alopecia Areata
Ebastine may help regrow hair in alopecia areata patients.
research Unique Amino Acid Signatures That Are Evolutionarily Conserved Distinguish Simple-Type, Epidermal, and Hair Keratins
This study found that keratins have evolutionarily conserved and domain-selectively enriched amino acids, which likely reflect their unique structural roles, with distinct patterns observed among epidermal, hair, and simple-type epithelial keratins.
research Metabolomic Biomarkers in Women with Polycystic Ovary Syndrome: A Pilot Study
This study suggests that women with polycystic ovary syndrome may have a distinct metabolomic profile, differing in levels of amino acids, organic acids, and lipids compared to controls.
research Proteomic Tools for the Investigation of Human Hair Structural Proteins and Evidence of Weakness Sites on Hair Keratin Coil Segments
This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.
research Prevalence of Nutritional Deficiencies in Hair Loss Among Indian Participants: Results of a Cross-Sectional Study
This study found that nutritional deficiencies, particularly in amino acids and certain micronutrients, are common in individuals with hair loss across all types of alopecia.
research Cataracts and Strabismus Associated with Hand Rearing Using Artificial Milk Formulas in Bengal Tiger (Panthera Tigris Spp Tigris) Cubs
This study suggests that deficiencies in certain amino acids, like taurine and tryptophan, in artificial milk formulas may contribute to skin and eye problems in Bengal tiger cubs.
research Hair and Amino Acids: The Interactions and the Effects
This study discusses the effects of incorporating various amino acids in hair care products, noting improvements in hair surface properties and color retention when integrated with conditioners.
research Extracellular Signal-Regulated Kinase Mediates Ebastine-Induced Human Follicle Dermal Papilla Cell Proliferation
In this study, ebastine significantly increased the proliferation of human follicle dermal papilla cells and may contribute to hair regrowth by activating the ERK signaling pathway.
research Comparative Studies of Hair Shaft Components Between Healthy and Diseased Donors
This study examined hair mineral and free amino acid components in various diseases and found that when using effect size analysis, specific components related to diabetes and other conditions were identified, suggesting their potential as novel health indicators.
research Evaluation of a Novel Graft-Holding Solution in Hair Transplantation: A Randomized Controlled Clinical Study
This study found that using histidine-tryptophan-ketoglutarate solution with adenosine triphosphate and deferoxamine for hair graft preservation significantly reduced postsurgical shedding compared to Ringer solution, enhancing patient satisfaction.
