Résumé
Dandruff is characterised by the presence of perivascular leukocytes and mild inflammation; however, the immune microenvironment of dandruff-affected scalp skin and the potential changes to the hair follicle's (HF) physiological immune privilege (HF IP) remain unknown. Here, we characterised the HF immune microenvironment and immune privilege status in dandruff-affected scalp skin. We assessed relevant key parameters in healthy versus dandruff-affected human scalp biopsies using quantitative immunohistomorphometry, laser capture microdissection, and RNA sequencing. The number of epidermal CD4 Together, this work shows that dandruff is associated with epidermal T-cell infiltration and a weakened HF IP in the suprabulbar ORS of HFs in dandruff lesional scalp. Les pellicules sont caractérisées par la présence de leucocytes périvasculaires et une légère inflammation. Cependant, le microenvironnement immunitaire de la peau du cuir chevelu affectée par les pellicules et les modifications potentielles du privilège immunitaire physiologique du follicule pileux (PI FP) restent inconnus. Ici, nous avons caractérisé le microenvironnement immunitaire du follicule pileux (FP) et l’état du privilège immunitaire de la peau du cuir chevelu affectée par les pellicules. MÉTHODES: Nous avons évalué les principaux paramètres pertinents dans des biopsies de cuir chevelu humain sain par rapport à ceux touchés par les pellicules, à l’aide d’une immuno-histomorphométrie quantitative, d’une microdissection au laser et d’un séquençage de l’ARN. RÉSULTATS: Le nombre de lymphocytes T CD4 L’ensemble de ces travaux montrent que les pellicules sont associées à une infiltration épidermique des lymphocytes T et à un affaiblissement du PI FP dans la GRE suprabulbaire des FP du cuir chevelu atteint de pellicules lésionnelles.
