Psoriasis
Proportion of CD4+CD49b+LAG-3+ Type 1 Regulatory T Cells in the Blood of Psoriasis Patients Inversely Correlates with Psoriasis Area and Severity Index
Psoriasis skin lesions are created through chronic T-cell activation and expansion of autoreactive, skin resident αβ T helper type 17 (Th17) cell clones (Matos et al., 2017), suggesting a defect in normal tolerance mechanisms. A previous study determined that although psoriasis patients have normal numbers of circulating regulatory T (Treg) cells (CD4+CD25+Foxp3+ T cells), psoriatic Treg cells were less effective at suppressing alloreactive T cells compared with Treg cells from healthy individuals (Bovenschen et al., 2011; de Boer et al., 2007; Sugiyama et al., 2005).Reduction of Inflammatory and Cardiovascular Proteins in the Blood of Patients with Psoriasis: Differential Responses between Tofacitinib and Etanercept after 4 Weeks of Treatment
Patients with psoriasis have an increased risk of myocardial infarction, and psoriasis is now recognized as an independent risk factor for coronary heart disease and cardiovascular mortality. To understand the effects of psoriasis medications on systemic inflammation associated with cardiovascular risks, we studied blood proteins related to inflammation and cardiovascular disease archived from a phase 3 clinical trial of tofacitinib and etanercept in adults with moderate-to-severe psoriasis. A total of 157 blood proteins were quantified by a proximity extension assay from 266 patients at baseline and week 4.
