Project description:This study investigated the underlying inflammatory pathways and cell types in hidradenitis suppurativa using transcriptomic approaches with RNA sequencing of lesional and non-lesional skin biopsies from hidradenitis suppurativa patients.
Project description:Molecular taxonomy and key signaling pathways of apocrine glands of patients with hidradenitis suppurativa were studied by whole transcriptome profiling. Dysregulated genes were detected by comparing lesional and non lesional skin obtained from male and female HS patients using the Agilent array platform.

Project description:Hidradenitis suppurativa is a common, debilitating inflammatory skin disease linked to immune dysregulation and abnormalities in follicular structure and function. Few studies have characterized the transcriptomic profile of affected and unaffected skin. We established an RNA-Seq based hidradenitis suppurativa expression disease signature and found it largely concordant with an earlier microarray-based study. We confirmed known aspects of the underlying disease biology including known immune response pathways, differential regulation of antimicrobial peptides, and complement activation. We further characterize the extent of changes in the complement cascade in hidradenitis lesions and highlight a signature that implicates host response to bacteria in disease pathogenesis.
Project description:To increase disease understanding and investigate cell types and pathways active in Hidradenitis suppurativa, skin was collected from patients who had surgical removal of affected skin regions. Blocks of tissue were taken from regions defined as lesional and non-lesional. For comparison blocks of skin were also collected from healty people undergoing plastic surgery
Project description:Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder with significant morbidity. The pathogenesis remains incompletely understood although immune dysregulation plays an important role. It is challenging to treat and approximately 50% of patients respond clinically to adalimumab, the only licensed treatment.
Project description:To acquire a better understanding of the molecular pathogenesis of hidradenitis suppurativa (HS), we performed mRNA microarray studies to compare whole blood gene expression of HS patients to that of healthy normal subjects. No significant difference was observed in whole blood mRNA expression between HS patients and healthy normal control. Whole blood samples were collected from patients with hidradenitis (n=16) at baseline and healthy normal subjects (n=10) for RNA extraction and microarray analysis.
Project description:Hidradenitis suppurativa (HS) is a highly prevalent, morbid inflammatory skin disease with limited treatment options. The major cell types and inflammatory pathways in skin of HS patients are poorly understood. We profiled via scRNASeq myeloid cells and keratinocytes sort-purified from two healthy skin samples and two samples with HS pathology to determine major cell types and transcriptional pathways altered in HS.
