Research cited in this study

9 / 9 results

research Alopecia Areata: Animal Models Illuminate Autoimmune Pathogenesis and Novel Immunotherapeutic Strategies

82 citations , March 2016 in “Autoimmunity reviews”

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

research The Autoimmune Basis of Alopecia Areata: A Comprehensive Review

162 citations , October 2014 in “Autoimmunity reviews”

This review discusses alopecia areata, highlighting its autoimmune aspects, environmental triggers, and current treatment options, but reports no new clinical results; recent studies suggest JAK pathway intervention may offer therapeutic potential.

research Recent Advances in the Pathogenesis of Autoimmune Hair Loss Disease Alopecia Areata

106 citations , January 2013 in “Clinical and Developmental Immunology”

This review discusses the pathogenesis of alopecia areata, highlighting the role of immune privilege collapse in hair follicles but reports no clinical results.

research Histopathology of Alopecia Areata, Acute and Chronic: Why Is It Important to the Clinician?

43 citations , May 2011 in “Dermatologic Therapy”

This article discusses the phases and histological features of alopecia areata and reports no new clinical findings; the authors emphasize recognizing these phases for accurate diagnosis.

research Primary Follicular Dystrophy With Scarring Dermatitis in C57BL/6 Mouse Substrains Resembles Central Centrifugal Cicatricial Alopecia in Humans

56 citations , September 2010 in “Veterinary pathology”

This study found that certain C57BL/6 mouse substrains have a genetic vulnerability to skin lesions resembling central centrifugal cicatrical alopecia in humans, potentially worsened by high vitamin A levels.

research Maintenance of Hair Follicle Immune Privilege Is Linked to Prevention of NK Cell Attack

253 citations , December 2007 in “Journal of Investigative Dermatology”

This study suggests that human hair follicles may actively suppress natural killer cells, which contrasts with the observed defects in NK cell regulation in alopecia areata.

research Lymphocytes, Neuropeptides, And Genes Involved In Alopecia Areata

286 citations , August 2007 in “Journal of Clinical Investigation”

This review examines the interplay of genetics and neuroimmunology in alopecia areata, highlighting its potential to inform broader autoimmunity research, but reports no new findings.

research Transient CD44 Variant Isoform Expression and Reduction in CD4+/CD25+ Regulatory T Cells in C3H/HeJ Mice with Alopecia Areata

77 citations , June 2002 in “Journal of Investigative Dermatology”

CD44 variant changes start alopecia areata, but don't maintain it.

research Alopecia Areata in Aging C3H/HeJ Mice

178 citations , June 1994 in “Journal of Investigative Dermatology”

This study found that a non-scarring alopecia in C3H/HeJ mice resembles human alopecia areata and may serve as a valuable model for studying specific subtypes of the human condition.
