Abstract
Psoriasis is a complex disease of skin with a prevalence of about 2%. We conducted the largest meta-analysis of genome-wide association studies (GWAS) for psoriasis to date, including data from eight different Caucasian cohorts, with a combined effective sample size >39,000 individuals. We identified 16 additional psoriasis susceptibility loci achieving genome-wide significance, increasing the number of identified loci to 63 for European-origin individuals. Functional analysis highlighted the roles of interferon signalling and the NFκB cascade, and we showed that the psoriasis signals are enriched in regulatory elements from different T cells (CD8+ T-cells and CD4+ T-cells including TH0, TH1 and TH17). The identified loci explain ∼28% of the genetic heritability and generate a discriminatory genetic risk score (AUC=0.76 in our sample) that is significantly correlated with age at onset (p=2 × 10-89). This study provides a comprehensive layout for the genetic architecture of common variants for psoriasis.

High throughput sequencing reveals the diversity of TRB-CDR3 repertoire in patients with psoriasis vulgaris. Int Immunopharmacol 2016; 40:487-491. [PMID: 27743555 DOI: 10.1016/j.intimp.2016.10.004] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2016] [Revised: 09/29/2016] [Accepted: 10/07/2016] [Indexed: 12/13/2022]
Abstract
Psoriasis is a T cell-mediated chronic inflammatory skin disease with inflammatory cell infiltrates in the dermis and epidermis. Previous studies suggested that there are some expanded T-cell receptor (TCR) clones in psoriatic skin. However, the effect of psoriasis on the immunological characteristics of TCR in circulating blood has not been reported. To address this, we performed high-throughput sequencing to reveal the immunological characteristics of TCR beta chain (TRB) in both psoriasis patients and healthy controls. Our results revealed that the TRB-CDR3 region of psoriasis patients had distinctive immunological characteristics compared with that of healthy controls, including V gene usage, nt of N addition. In addition, three types of TRB-CDR3 peptides were found highly relevant to psoriasis. Our findings show the comprehensive characteristics of psoriasis on the TRB-CDR3 repertoire of circulating blood at sequence-level resolution. These findings may contribute to a better understanding of the pathogenesis of psoriasis and open opportunities to explore potential therapeutic targets.
