CRF receptor antagonist Astressin-B alopecia hair regrowth pigmentation CRF signaling stress-induced hair loss

Studysummary This study found that blocking corticotropin-releasing factor receptors with astressin-B promoted hair regrowth and prevented alopecia in a mouse model of stress-induced hair loss. Our plain-language summary of this paper — not a Tressless recommendation.

The study demonstrated that the CRF receptor antagonist Astressin-B effectively reversed and prevented alopecia in CRF over-expressing mice by inducing significant hair regrowth and pigmentation, with effects lasting up to 4 months. This suggested that CRF signaling played a significant role in stress-induced hair loss, and blocking this pathway could be a potential therapeutic strategy for treating alopecia. The findings highlighted the potential of CRF receptor antagonists as a promising therapy for stress-related hair loss.

137 citations , January 2006 in “Frontiers in bioscience”

This review discusses the role of corticotropin-releasing hormone in human skin, focusing on its regulation, receptors, and functions, and highlights parallels with the hypothalamo-pituitary-adrenal axis; it reports no new research findings.

research Hair Growth Inhibition by Psychoemotional Stress: A Mouse Model for Neural Mechanisms in Hair Growth Control

127 citations , December 2005 in “Experimental Dermatology”

This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

research Hair Melanocytes as Neuro-Endocrine Sensors—Pigments for Our Imagination

43 citations , October 2005 in “Molecular and cellular endocrinology”

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

research Human Hair Follicles Display a Functional Equivalent of the Hypothalamic-Pituitary-Adrenal (HPA) Axis and Synthesize Cortisol

489 citations , June 2005 in “The FASEB Journal”

This study found that human scalp hair follicles can respond to corticotropin releasing hormone stimulation similarly to the classical HPA axis, including up-regulating cortisol production and activating neuroendocrine feedback loops.

research Two Mouse Mutations Mapped to Chromosome 11 with Differing Morphologies but Similar Progressive Inflammatory Alopecia

7 citations , May 2005 in “Experimental Dermatology”

This study reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

15 citations , April 2001 in “Journal of Dermatological Science”

This study found that KF19418 stimulated hair follicle growth in vitro and accelerated hair regrowth in a mouse alopecia model, with effects comparable to minoxidil.

research Melanogenesis Is Coupled to Murine Anagen: New Concepts for the Role of Melanocytes and Regulation of Melanogenesis in Hair Growth

109 citations , July 1993 in “The journal of investigative dermatology/Journal of investigative dermatology”

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.
