46 citations
,
October 2018 in “JCI insight” In this study, the researchers found that treatment with the JAK inhibitor tofacitinib in alopecia areata patients may reduce clonal CD8+ T cell expansions but does not eliminate them entirely, which could contribute to disease relapse.
45 citations
,
April 2001 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that Myc superfamily transcription factors may have distinct roles in different epithelial compartments of the human hair follicle, possibly influencing cell fate in the putative stem cell compartment.
43 citations
,
May 2011 in “Dermatologic therapy” This study identified at least eight genetic regions associated with alopecia areata, which may lead to the development of new targeted therapies based on these findings.
29 citations
,
April 2000 in “Journal of histochemistry and cytochemistry/The journal of histochemistry and cytochemistry” This study found that ICAM-1 expression in murine skin is developmentally regulated and crucial for skin and hair follicle remodeling beyond its recognized role in immune responses.
20 citations
,
May 2016 in “Journal of Cutaneous Pathology” This study suggests that the presence and arrangement of plasmacytoid dendritic cells can help distinguish chronic cutaneous lupus erythematosus from other types of scarring alopecia.
