    Associate Professor, Department of Rheumatology, Sifa University Faculty of Medicine, 35100-Bornova, Izmir, Turkey.
    Sarcoidosis is a systemic disorder of unknown etiology, which may involve various tissues and organs and is characterized by a noncaseating granuloma reaction. While pathogenesis is not yet clear, cellular immune system activation and nonspecific inflammatory response occur secondarily to several genetic and environmental factors. T helper 1-cells and macrophage-derived pro-inflammatory cytokines stimulate the inflammatory cascade and formation of granuloma occurs as a result of tissue permeability, cell influx, and local cell proliferation.

    Exonuclease TREX1 degrades double-stranded DNA to prevent spontaneous lupus-like inflammatory disease.
    Proc Natl Acad Sci U S A 2015 Apr 6;112(16):5117-22. Epub 2015 Apr 6.
    Department of Biochemistry, Center for Structural Biology, Wake Forest School of Medicine, Winston-Salem, NC 27157
    The TREX1 gene encodes a potent DNA exonuclease, and mutations in TREX1 cause a spectrum of lupus-like autoimmune diseases. Most lupus patients develop autoantibodies to double-stranded DNA (dsDNA), but the source of DNA antigen is unknown. The TREX1 D18N mutation causes a monogenic, cutaneous form of lupus called familial chilblain lupus, and the TREX1 D18N enzyme exhibits dysfunctional dsDNA-degrading activity, providing a link between dsDNA degradation and nucleic acid-mediated autoimmune disease.

    Proteasome-associated autoinflammatory syndromes: advances in pathogeneses, clinical presentations, diagnosis, and management.
    Int J Dermatol 2015 Feb 18;54(2):121-9. Epub 2014 Dec 18.
    College of Medicine, University of Arkansas for Medical Sciences, Little Rock, AR, USA.
    The disease spectrum currently known as the proteasome-associated autoinflammatory syndromes (PRAAS) was first described in 1939 in patients who presented with recurrent fevers beginning in infancy or early childhood, which were accompanied by nodular erythema, a pernio-like rash, and joint contractures. Since then, several syndromes, such as chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome, Nakajo-Nishimura syndrome (NNS), joint contractures, muscle atrophy, microcytic anemia and panniculitis-induced lipodystrophy (JMP) syndrome, and Japanese autoinflammatory syndrome with lipodystrophy (JASL), have been used to categorize patients with diseases within the same spectrum. Recently, independent studies have identified mutations in the human proteasome subunit β type 8 (PSMB8) gene, which result in a sustained inflammatory response in all syndromes. Read More
