Studysummary This study developed and analyzed a mathematical model for alopecia areata involving interactions among immune cells and cytokines, establishing conditions under which hairless patches can become stable and pervasive, particularly with certain biological rate levels and chemotactic sensitivities.

research Clinical and Genetic Aspects of Alopecia Areata: A Cutting Edge Review

1 citations , June 2023 in “Genes”

This study highlights the genetic complexities in alopecia areata, emphasizing the role of microRNAs and their association with other immune-related diseases, which could inform targeted treatment strategies.

research Lifestyle Factors Involved in the Pathogenesis of Alopecia Areata

16 citations , January 2022 in “International journal of molecular sciences”

This review summarizes the influences of lifestyle factors such as smoking, alcohol, and diet on the pathogenesis of alopecia areata but reports no new clinical results.

research Alopecia Areata: A Multifactorial Autoimmune Condition

148 citations , December 2018 in “Journal of autoimmunity”

This review discusses genetic and environmental factors contributing to autoimmunity in alopecia areata and reports no new clinical findings, emphasizing the need for further study on its aetiology and pathophysiology.

research Mathematical Model for Alopecia Areata

6 citations , June 2015 in “Journal of theoretical biology”

This study suggests that immune privilege guardians and the pro-inflammatory cytokine interferon-γ significantly influence the dynamics of alopecia areata, supporting the hypothesis that immune privilege collapse is crucial in its development.

research Alopecia Areata: An Autoimmune Disease Causing Hair Loss

421 citations , April 2012 in “The New England Journal of Medicine”

Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.
