Replicative Stress in Hair Follicle Stem Cells and Pathogeny of Hidradenitis Suppurativa — Fol-Hydra  

Hidradenitis Suppurativa Clinical Trial

Official title:
Replicative Stress in Hair Follicle Stem Cells and Pathogeny of Hidradenitis Suppurativa

Clinical Trial Summary

Hidradenitis Suppurativa is a recurrent chronic inflammatory follicular occlusive disease affecting hair follicles. HS is notoriously difficult and challenging to treat with a high morbidity impact and could be classified as an unmet medical need with no efficient therapeutic options. Objective: Investigators previously showed that Outer Root Sheath Cells (ORS) isolated from hair follicle of HS patients (HS-ORS) have a pro-inflammatory phenotype and secrete spontaneously IP-10 and RANTES. To identify the mechanisms involved in the pro-inflammatory phenotype of HS-ORS, investigators performed a transcriptomic analysis in healthy and HS patients. This revealed: (i) an IFN signature, (i) a dysregulation of genes involved in cell proliferation and differentiation, and (iii) an upregulation of DNA damage response and cell cycle G2/M checkpoint pathways in HS-ORS. These findings support the notion that, in HS patients, a perturbation of HF-SC homeostasis leading to an increased proliferation induces a replicative stress and an accumulation of cytoplasmic ssDNA, stimulating IFN synthesis through IFI16-STING pathway. Interestingly, replicative stress in ORS were present in some but not all patients with Hidradenitis Suppurativa. The goal of study is to determine replicative stress in ORS in a large cohort of HS patients. Method Patients will be enrolled in the Mondor Dermatology department, during routine care. A dermatologist will check all inclusion and exclusion criteria with the technical support of a research technician of the Henri Mondor Clinical Investigation Center. Medical history, clinical data, comorbidities and concomitant therapies will be prospectively recorded in a dedicated case report form. Skin biopsies will be performed in perilesional zone rich in hair follicles. mRNA will be extracted from freshly isolated hair follicle cells and some slides will be prepared and stored at -80°C to perform immunohistochemistry analysis on freshly isolated hair follicle cells. PBMC and serum will be collected. All these biological samples will allow us to quantify the replicative stress in HS-ORS of each patient, and to quantify several cytokine of interest : IFN de type 1, IL-17, IL-6, TNF-α, IL-10 This study will allow investigators to evaluate the rate of patients with replicative stress in hair follicle stem cells in Hidradenitis Suppurativa. The investigator will also determine whether HF-SC replication stress correlates with clinical characteristics and/or with clinical course and/or comorbidities.
