There is less overlap reported with rheumatoid arthritis (RA) than PsV susceptibility loci but one report suggests that the AFF3 locus may be associated with both RA and PsA.
The aim of this study was to investigate serum concentrations of AhR, cytochromes P450 (CYP) 1A1 and 1B1 in patients with exacerbated psoriasis vulgaris treated with combined therapy of ultraviolet radiation (UVR) and crude coal tar.
Compared with normal skin tissues, PV skin tissues showed increased protein oxidation as well as down-regulation of Nrf2 and its regulatory proteins such as HO-1 and AKR1C3.
However, the distribution of the other genotypes (rs2507800, rs1954727 and rs1010824 of ANGPT1; rs3739390 and rs1868554 of ANGPT2; and rs507879, rs518604 and rs523104 of caspase-5) was not significantly different between patients with PV and the HCs.
To evaluate the role of changes in expression of apoptosis activators [B-cell lymphoma (Bcl)-2-like protein 4 (BAX), cytochrome c (cytC) and caspase-3 (CASP3)] and apoptosis inhibitors [Bcl-2, survivin, cyclin D1 (CCND1), superoxide dismutase (SOD), catalase 3 (CAT), glutathione synthetase (GS), heat shock protein (Hsp)27, Hsp60, Hsp70 and Hsp90] on development of MetS in patients with psoriasis vulgaris.

Then we performed a hospital-based study in order to evaluate the combined effect of the risk factors and their related polymorphism rs6265 in brain-derived neurotrophic factor (BDNF) gene on psoriasis vulgaris (PV) risk and clinic traits.
The study aimed at adding more insight on the role played by co-inhibitory molecule BTLA in psoriasis vulgaris and its inter-relation with RORγt and IL-7 to establish a basis for novel treatment strategies.
The results of the present study indicate that the HLA-DPB1*05:01 gene was associated with the geographical region of PV and the BTNL2 gene was significantly associated with family history and age of onset of PV.
Mechanistically, the entities include generalized pustular psoriasis (GPP) without psoriasis vulgaris, impetigo herpetiformis and acrodermatitis continua, which are IL-36Ra-related pustuloses caused by loss-of-function mutations in IL36RN; GPP with psoriasis vulgaris and palmoplantar pustular psoriasis which are CARD14-mediated pustular psoriasiform dermatoses with gain-of-function variants of CARD14; PRP type V which is caused by gain-of-function mutations in CARD14; and, familial KLC in which mutations in NLRP1, an inflammasome sensor protein predominantly expressed in skin, have been identified.
