The Preferential Use of Anakinra in Various Settings of FMF: A Review Applied to an Updated Treatment-Related Perspective of the Disease.

Int J Mol Sci 2022 Apr 2;23(7). Epub 2022 Apr 2.

FMF Clinic, The Chaim Sheba Medical Center, Tel-Hashomer, Ramat-Gan 5265601, Israel.

Familial Mediterranean fever (FMF), the most frequent monogenic autoinflammatory disease, is manifested with recurrent and chronic inflammation and amyloid A (AA) amyloidosis, driven by overproduction of interleukin 1 (IL-1) through an activated pyrin inflammasome. Consequently, non-responsiveness to colchicine, the cornerstone of FMF treatment, is nowadays addressed by IL-1- blockers. Each of the two IL-1 blockers currently used in FMF, anakinra and canakinumab, has its own merits for FMF care. Read More

Global Proteotoxicity Caused by Human β Microglobulin Variants Impairs the Unfolded Protein Response in .

Int J Mol Sci 2021 Oct 4;22(19). Epub 2021 Oct 4.

Faculty of Biological Sciences, School of Molecular and Cell Biology & Astbury Centre for Structural Molecular Biology, University of Leeds, Leeds LS2 9JT, UK.

Aggregation of β microglobulin (βm) into amyloid fibrils is associated with systemic amyloidosis, caused by the deposition of amyloid fibrils containing the wild-type protein and its truncated variant, ΔN6 βm, in haemo-dialysed patients. A second form of familial systemic amyloidosis caused by the βm variant, D76N, results in amyloid deposits in the viscera, without renal dysfunction. Although the folding and misfolding mechanisms of β microglobulin have been widely studied in vitro and in vivo, we lack a comparable understanding of the molecular mechanisms underlying toxicity in a cellular and organismal environment.
