Interleukin-33 (IL-33) is a new cytokine of interleukin-1 family, whose specific receptor is ST2. IL-33 exerts its functions via its target cells and plays different roles in diseases. ST2 deletion and exclusion of IL-33/ST2 axis are accompanied by enhanced susceptibility to dominantly T cell-mediated organ-specific autoimmune diseases. It has been reported that IL-33/ST2 pathway plays a key role in host defense and immune regulation in inflammatory and infectious diseases. This review focuses on new findings in the roles of IL-33 and ST2 in several kinds of T cell-mediated autoimmune diseases.

Positron Emission

In the last years, an increasing interest in molecular imaging has been raised by the extending potential of positron emission tomography [PET]. The role of PET imaging, originally confined to the oncology setting, is continuously extending thanks to the development of novel radiopharmaceutical and to the implementation of hybrid imaging techniques, where PET scans are combined with computed tomography [CT] or magnetic resonance imaging[MRI] in order to improve spatial resolution. Early preclinical studies suggested that 18F–FDG PET can detect neuroinflammation; new developing radiopharmaceuticals targeting more specifically inflammation-related molecules are moving in this direction. Neurological involvement is a distinct feature of various systemic autoimmune diseases, i.e. Systemic Lupus Erythematosus [SLE] or Behcet’s disease [BD]. Although MRI is largely considered the gold-standard imaging technique for the detection of Central Nervous System [CNS] involvement in these disorders. Several patients complain of neuropsychiatric symptoms [headache, epilepsy, anxiety or depression] in the absence of any significant MRI finding; in such patients the diagnosis relies mainly on clinical examination and often the role of the disease process versus iatrogenic or reactive forms is doubtful. The aim of this review is to explore the state-of-the-art for the role of PET imaging in CNS involvement in systemic rheumatic diseases. In addition, we explore the potential role of emerging radiopharmaceutical and their possible application in aiding the diagnosis of CNS involvement in systemic autoimmune diseases.

Although mobile genetic elements, or transposons, have played an important role in genome evolution, excess activity of mobile elements can have detrimental consequences. Already, the enhanced expression of transposons-derived nucleic acids can trigger autoimmune reactions that may result in severe autoinflammatory disorders. Thus, cells contain several layers of protective measures to restrict transposons and to sense the enhanced activity of these “intragenomic pathogens”. This review focuses on our current understanding of immunogenic patterns derived from the most active elements in humans, the retrotransposons long interspersed element (LINE)-1 and Alu. We describe the role of known pattern recognition receptors in nucleic acid sensing of LINE-1 and Alu and the possible consequences for autoimmune diseases.

Abstract Purpose Genetically predisposed individuals may develop several autoimmune diseases—autoimmune polyendocrine syndromes (APS). APS types 2–4, are complex disorders, which combine various organ-specific autoimmune conditions. Recent reports support the considerable role of the BACH2 gene in immune cell differentiation and shifting the T-cell balance towards regulatory T-cells. BACH2 polymorphisms are associated with autoimmune disorders, including Addison’s disease (AD), Graves’ disease (GD), and probably type 1 diabetes (T1D). Our study was aimed to investigate the BACH2 variant, rs3757247, in endocrine autoimmunity in the Polish population. Methods The analysis comprised 346 individuals with APS, 387 with T1D only, and 568 controls. Genotyping was performed using TaqMan chemistry. Results APS type 2 was found in 219 individuals, type 3 in 102, and type 4 in 25 subjects. Overall, AD was diagnosed in 244 subjects, Hashimoto’s thyroiditis—in 238, T1D—in 127, GD—in 58, vitiligo and chronic gastritis each in 40 patients, celiac disease—in 28, premature menopause in 18, and alopecia in 4 patients. Minor T allele at rs3757247 was found in 56.4% APS vs. 44.1% control alleles (OR 1.59; 95%CI: 1.30–1.95, p < 0.0001). The distribution of genotypes revealed excess TT homozygotes in the APS cohort (33.2 vs. 20.1% in controls, p < 0.0001). The frequencies of rs3757247 alleles and genotypes in T1D patients did not present significant differences vs. controls (p-values > 0.05). Conclusions These results provide evidence of the association between BACH2 polymorphism and polyglandular autoimmunity. Since carriers of rs3757247 display increased risk for additional autoimmune conditions, this variant could identify individuals prone to develop APS.
