trypsin serine protease apoptosis follicular papilla hair growth pigmentation receptor-mediated signaling pathway programmed cell death

Studysummary This study found that topical trypsin application after hair removal in mice led to cell death at the follicular papilla, which delayed hair growth and pigmentation.

Research cited in this study

14 / 14 results

research Cytokines and Growth Factors Influence Hair Growth In Vitro: Possible Implications for the Pathogenesis and Treatment of Alopecia Areata

91 citations , March 1996 in “Archives of Dermatological Research”

This study concluded that cytokines and growth factors significantly regulate hair growth in vitro, with some completely inhibiting growth, such as EGF and TNFα.

research Message of Nexin 1, a Serine Protease Inhibitor, Accumulates in the Follicular Papilla During Anagen of the Hair Cycle

37 citations , December 1995 in “Journal of Cell Science”

This study found that nexin 1 mRNA, a potent protease inhibitor, is prevalent in rat follicular papilla cells and may play a role in regulating hair follicular growth.

research Expression of the Bcl-2 Proto-Oncogene in the Cycling Adult Mouse Hair Follicle

122 citations , July 1994 in “Journal of Investigative Dermatology”

research IL-1 Alpha Inhibits Human Hair Follicle Growth And Hair Fiber Production In Whole-Organ Cultures

30 citations , August 1993 in “PubMed”

This study found that IL-1 alpha inhibits the growth of cultured human hair follicles and hair fibers, suggesting a potential role in inflammatory hair loss conditions like alopecia areata.

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

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

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

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

research Hair Follicle Stem Cells: Their Location, Role in Hair Cycle, and Involvement in Skin Tumor Formation

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

research The Control of Hair Growth: An Overview

62 citations , July 1993 in “Journal of Investigative Dermatology”

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

research Glucocorticoid Effect on Hair Growth Initiation: A Reconsideration

77 citations , January 1993 in “Skin Pharmacology and Physiology”

In this study, topically applied glucocorticosteroids were found to block hair growth at the stage of hair formation, but not the initiation of hair growth, in a mouse model.

research Induction of Follicle Formation and Hair Growth by Vibrissa Dermal Papillae Implanted into Rat Ear Wounds: Vibrissa-Type Fibres Are Specified

125 citations , August 1992 in “Development”

This study found that implanting isolated adult rat dermal papillae into ear cuts led to the emergence of unusually large vibrissa-type hair follicles, demonstrating their capacity to induce specific hair fiber characteristics.

research The Secret Life of the Hair Follicle

745 citations , February 1992 in “Trends in genetics”

This article describes the potential role of various growth factors and molecules in regulating mammalian hair follicle development but does not present new experimental results.

research Distribution of Extracellular Matrix Molecules in Human Hair Follicles

45 citations , December 1991 in “Annals of the New York Academy of Sciences”

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

research Inductive Properties of Hair Follicle Cells

68 citations , December 1991 in “Annals of the New York Academy of Sciences”

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

research The Dermal Papilla and Maintenance of Hair Growth

38 citations , January 1988

research Growth of the Hair

521 citations , January 1954 in “Physiological Reviews”

Hair growth is cyclic and influenced mainly by local factors.
