CD4 T lymphocyte autophagy is upregulated in the salivary glands of primary Sjögren’s syndrome patients and correlates with focus score and disease activity
Background Primary Sjögren’s syndrome (pSS) is a common chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands and peripheral lymphocyte perturbation. In the current study, we aimed to investigate the possible pathogenic implication of autophagy in T lymphocytes in patients with pSS. Methods Thirty consecutive pSS patients were recruited together with 20 patients affected by sicca syndrome and/or chronic sialoadenitis and 30 healthy controls. Disease activity and damage were evaluated according to SS disease activity index, EULAR SS disease activity index, and SS disease damage index. T lymphocytes were analyzed for the expression of autophagy-specific marke…
SAT0378 Autophagy is Up-Regulated in the Salivary Glands of Primary Sjogren's Syndrome Patients and Correlates with the Focus Score and Disease Activity
Background Autophagy is now considered as a major regulator in trafficking events that activates innate and adaptive immunity and consistent evidence supports its role in autoimmunity (1). Primary Sjogren9s syndrome (pSS) is a systemic autoimmune disease characterized by infiltration of exocrine glands by T and B cells that, producing chemokines and cytokines, coordinate the chronic inflammatory process. No data on the role of autophagy in pSS are available in humans, although studies in mice demonstrated its involvement in the salivary and lacrimal gland homeostasis (2,3). Objectives We investigated the autophagy process in salivary gland tissue and in peripheral T lymphocytes from pSS pat…
OP0299 Serum and glomerular expression of IL32 in lupus nephritis
Background Lupus nephritis (LN) is one of the most severe features of systemic lupus erythematosus (SLE). Several cytokines and chemokines are secreted locally in case of glomerular inflammation. Interleukin 32 (IL32) is a newly described cytokine that exhibits several properties typical of proinflammatory cytokines. Ex vivo and in vitro studies supported the role of Toll like receptors (TLRs) in LN pathogenesis and recent investigations demonstrated that Poly I:C, a ligand for (TLR) 3, strongly induced IL32 production from several cell populations. Objectives To investigate serum and urinary levels of IL32 in a cohort of LN patients compared to SLE patients without renal involvement and he…
Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition) 1
Contains fulltext : 232759.pdf (Publisher’s version ) (Closed access) In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to…

Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide…
