Extensive alopecia areata is reversed by IL-23 cytokine antagonism

ABSTRACT: Alopecia areata (AA) is a prevalent disease associated with major emotional distress, and lacks effective, safe therapeutics for patients with extensive hair loss. This is the first report of hair regrowth with specific cytokine antagonism, in three patients with extensive hair loss ranging from 40% scalp involvement to alopecia universalis. Ustekinumab, an IL-12/23p40 antagonist that is highly effective in psoriasis, showed impressive ability to induce hair regrowth, coupled with suppression of inflammatory pathways and upregulation of hair keratins. Our report suggests that extensive AA is reversible using targeted treatments, opening the door for specific cytokine antagonism for this debilitating disease. We evaluated hair regrowth in three AA patients at 20 weeks after treatment with 3 subcutaneous doses of 90mg ustekinumab given at weeks 0, 4, and 16. Skin biopsies of lesional and non-lesional scalp (when available) were taken at baseline (week 0) and at week 20. We also obtained biopsies from three healthy individuals.

JAK3/TEC and TYK2/JAK1 inhibitors demonstrate significant improvement in scalp alopecia areata biomarkers

Project description:We present the biopsy sub-study results from the first randomized, placebo-controlled clinical trial in patients with alopecia areata (AA) with ≥50% scalp hair loss and ≤7 years since the last AA episode. In this sub-study, we evaluated the molecular responses to PF-06651600, an oral inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, and PF-06700841, an oral TYK2/JAK1 inhibitor, versus placebo in nonlesional and lesional scalp biopsies of biopsy samples from patients with AA.

Plucked hair follicles from patients with chronic discoid lupus erythematosus show a disease-specific molecular signature

Project description:When faced with clinical symptoms of scarring alopecia – the standard diagnostic pathway involves a scalp biopsy which is an invasive and expensive procedure. Furthermore, clinical activity of scarring alopecias is often difficult to assess as symptoms of permanent damage and signs of activity can overlap or be difficult to distinguish. Here we report that gene expression analysis of only a small number of hair follicles (HF) plucked from lesional areas of the scalp is sufficient to characterise chronic discoid lupus erythematosus (CDLE). Lesional and non-lesional HFs were extracted from the scalp of patients with CDLE, psoriasis and healthy controls. The expression profile from CDLE HFs coincides with published profiles of CDLE from skin biopsy and was consistent with histopathological diagnostic features of CDLE. We therefore propose that information obtained from this non-invasive approach are sufficient to diagnose scalp LE.

Profibrotic subsets of SPP1+ macrophages and POSTN+ fibroblasts contribute to fibrotic scarring in acne keloidalis

Project description:Acne keloidalis (AK) is a primary scarring alopecia characterized by longstanding inflammation in the scalp leading to keloid-like scar formation and hair loss. Histologically, AK is characterized by mixed leukocytic infiltrates in the acute stage followed by a granulomatous reaction and extensive fibrosis in later stages. To further explore its pathogenesis, bulk RNA-sequencing and single-cell RNA sequencing were applied to scalp biopsy specimens of lesional and adjacent non-lesional skin in patients with clinically active disease. Unbiased clustering revealed 18 distinct cell populations, including two notable populations, POSTN+ fibroblasts with enriched extracellular matrix signatures, and SPP1+ myeloid cells M2 macrophages. Cell communication analyses indicate that fibroblasts and myeloid cells communicate by collagen and SPP1 signaling networks in lesional skin. Tissue immunofluorescence staining demonstrated SPP1+ myeloid cells and POSTN+ fibroblasts at the upper segment of outer root sheath of the hair follicle in the subacute stage, confirming micro-anatomic specificity with relevant disease activity. Therapy with intralesional corticosteroids reduced SPP1 and POSTN expression, and lessened AK progression. In summary, the communication between POSTN+ fibroblasts and SPP1+ myeloid cells by collagen and SPP1 axis may contribute to the pathogenesis of AK.

Metabolomics Analysis of Frontal Fibrosing Alopecia

Project description:Scarring alopecia consists of a collection of disorders characterized by destruction of hair follicles, replacement with fibrous scar tissue, and irreversible hair loss. Alopecia affects men and women worldwide and can be a significant source of psychological stress and depression for affected individuals. The purpose of this study was to explore metabolic profiles in scalp tissue samples from normal control subjects (n=6) and in matched samples obtained from affected (n=12) and unaffected (n=12) areas of the scalp in patients with lymphocytic Frontal Fibrosing Alopecia (FFA). Frontal fibrosing alopecia results from destruction of hair follicles by an inflammatory lymphocytic infiltrate that is localized around the upper portion of the hair follicle.

Prostaglandin D2 Inhibits Hair Growth and Is Elevated in Bald Scalp of Men with Androgenetic Alopecia

Project description:Testosterone is necessary for the development of male pattern baldness, known as androgenetic alopecia (AGA); yet the mechanisms for decreased hair growth in this disorder are unclear. Here, we show that prostaglandin D2 synthase (PTGDS) is elevated at the mRNA and protein levels in bald scalp compared to haired scalp of men with AGA. The product of PTGDS enzyme activity, prostaglandin D2 (PGD2), is similarly elevated in bald scalp. During normal follicle cycling in mice Ptgds and PGD2 levels increase immediately preceding the regression phase, suggesting an inhibitory effect on hair growth. We show that PGD2 inhibits hair growth in explanted human hair follicles and when applied topically to mice. Hair growth inhibition requires the PGD2 receptor G protein-coupled receptor 44 (GPR44), but not the prostaglandin D2 receptor 1(PTGDR). Furthermore, we find that a transgenic mouse, K14-Ptgs2, which targets prostaglandin-endoperoxide synthase 2 expression to the skin, demonstrates elevated levels of PGD2 in the skin and develops alopecia, follicular miniaturization and sebaceous gland hyperplasia, which are all hallmarks of human AGA. These results define PGD2 as an inhibitor of hair growth in AGA and suggest the PGD2-GPR44 pathway as a potential target for treatment. 5 individuals with Androgenetic Alopecia were biopsied at both their haired and bald scalp for mRNA purification and microarray (total 10 arrays)

Expression profiling of lesional and non-lesional bulge cells from Lichen planopilaris patients

Project description:Lichen planopilaris (LPP) is a chronic inflammatory disease of unknown pathogenesis that leads to permanent hair loss. Whilst destruction of epithelial hair follicle stem cells (eHFSCs) that reside in an immunologically protected niche of the HF epithelium, the bulge, is a likely key event in LPP pathogenesis, this remains to be demonstrated. Laser capture microdissection of bulge cells from biopsies of lesional and non-lesional scalp skin from adult LPP patients were analyzed by microarray analysis.
