2. Figure 1
Location of human endogenous retrovirus K (HERV-K) sequence adjacent to HLA-C within the major histocompatibility complex region on chromosome 6. The PSORS1 susceptibility locus containing one or more psoriasis risk variants has been mapped in various studies to the region between HLA-B and HCG22. Cen: centromeric; Tel: telomeric. Scale at bottom is the human reference sequence assembly GRCh37/hg19.

IgG antibody responses against recombinant human endogenous retrovirus K (HERV-K) dUTPase. The response against HERV-K dUTPase was screened using 23 psoriasis patient serum samples and 16 healthy donor serum samples at a 1:800 dilution. The human dUTPase was used as a control. Psoriasis subjects had a greater humoral response against HERV-K dUTPase compared with the healthy blood donors. No response against the human dUTPase was detected even at the lowest dilution used (data not shown). *P<0.05, Mann–Whitney U-test.
