Canonical inflammasomes are innate immune protein scaffolds that enable the activation of inflammatory caspase-1, and subsequently the processing and release of interleukin (IL)-1β, IL-18, and danger signals, as well as the induction of pyroptotic cell death. Inflammasome assembly and activation occurs in response to sensing of infectious, sterile and self-derived molecular patterns by cytosolic pattern recognition receptors, including the Nod-like receptor NLRP3. While these responses are essential for host defense, excessive and uncontrolled NLRP3 inflammasome responses cause and contribute to a wide spectrum of inflammatory diseases, including gout.

Objectives: In the anifrolumab systemic lupus erythematosus (SLE) trial programme, there was one trial (TULIP-1) in which BILAG-based Composite Lupus Assessment (BICLA) responses favoured anifrolumab over placebo, but the SLE Responder Index (SRI(4)) treatment difference was not significant. We investigated the degree of concordance between BICLA and SRI(4) across anifrolumab trials in order to better understand drivers of discrepant SLE trial results.

Methods: TULIP-1, TULIP-2 (both phase 3) and MUSE (phase 2b) were randomised, 52-week trials of intravenous anifrolumab (300 mg every 4 weeks, 48 weeks; TULIP-1/TULIP-2: n=180; MUSE: n=99) or placebo (TULIP-1: n=184, TULIP-2: n=182; MUSE: n=102).

Potential Roles of Antiphospholipid Antibodies in Generating Platelet-C4d in Systemic Lupus Erythematosus.

Antibodies (Basel)

July 2017

Lupus Center of Excellence, Autoimmunity Institute, Allegheny Health Network Research Institute, Allegheny Health Network, Pittsburgh 15212, PA, USA.

Premature, accelerated onset of atherothrombotic disease is prevalent in patients with systemic lupus erythematosus (SLE). Most, if not all, atherothrombotic diseases are likely to involve platelets and complement. Previously, we discovered that platelets bearing complement activation product C4d (P-C4d) are present in SLE patients, and are significantly associated with antiphospholipid (aPL) antibody positivity and stroke in SLE patients.

Article Synopsis
  • Pulmonary arterial hypertension (PAH) is a rare disease featuring significant changes in blood vessel structure, which may be linked to inflammation caused by obesity-related fat deposits.
  • The study utilized advanced microCT imaging and proteomics to examine lung vascular remodeling and adipose tissue dysfunction in rats exposed to a specific treatment (Sugen 5416) and hypoxia.
  • Key findings indicate notable changes in lung vasculature and increased levels of proteins associated with fat dysfunction (C3 and FABP4) in the heart adipose of the treated rats, suggesting a connection between vascular issues and fat tissue impairment in PAH.
