The etiology of autoimmune diseases remains largely unknown but candidate etiologic factors include genetic abnormalities and infections. Although there are considerable data supporting the role of infections in a variety of autoimmune diseases, this role has been unequivocally established in only a few autoimmune diseases. The difficulty in establishing the infectious etiology of autoimmune diseases stems from several factors such as the heterogeneity of clinical manifestations in individual autoimmune diseases and the time interval between infection and autoimmune disease. The data on this association derive from clinical observations, epidemiological studies and research using laboratory techniques, protein sequence database screening and animal models. Infectious agents can cause autoimmune diseases by different mechanisms, which fall into two categories: antigen specific in which pathogen products or elements have a central role e.g. superantigens or epitope (molecular) mimicry, and antigen non-specific in which the pathogen provides the appropriate inflammatory setting for \"bystander activation\". The most important mechanisms are molecular mimicry and superantigens. As far as molecular mimicry is concerned the recent data on the degeneracy of T cell recognition shifted the focus from searching for linear sequence homology to looking for similarity of antigenic surfaces.

Enhanced inflammatory response and over-expression of proinflammatory cytokines are the prominent features of Behçet's disease, and they are compatible with the findings in other autoinflammatory disorders.

Angiogenesis occurs in several physiological and pathological conditions, such as embryo development and wound healing, diabetic retinopathy and tumours. Inflammatory cells, namely monocytes/macrophages, T lymphocytes and neutrophils, fully participate in the angiogenic process by secreting cytokines that may affect endothelial cell (EC) functions, including EC proliferation, migration and activation. Angiogenesis is the result of a net balance between the activities exerted by positive and negative regulators. With regards to inflammatory cells and endothelium cross-talk, such balance is conceptually very similar to that of pro-inflammatory and anti-inflammatory mediators that modulate an appropriate inflammatory response. In this review we will mainly discuss the relevance of both physiological and pathological inflammatory processes in angiogenesis, with particular regards to microenvironmental contribution. We will also describe some of the most relevant pro-inflammatory cytokines in the modulation of the angiogenic process. Furthermore, we will concentrate on what has been recently reported about the mechanism by which some of these cytokines are induced during inflammation to promote a suitable microenvironment for angiogenesis and tumour progression. Pro-angiogenic cytokines, such as IL-1 and TNF, and anti-angiogenic cytokines such as IFN-gamma and IL-12, will be briefly described. We will try to provide a rationale for the use of both cytokines and cytokine blockades as novel potential pharmaceutical targets to modulate angiogenesis in chronic inflammation as well as in cancer.</p>","PeriodicalId":86954,"journal":{"name":"Current drug targets.

It is the most prevalent of the hereditary periodic fever syndromes, a group of disorders characterized by episodic attacks of fever and inflammation. Seven years ago, it was discovered that FMF is caused by mutations in MEFV, a gene that encodes a protein variously called pyrin or marenostrin. As exciting as that discovery was, physicians and patients alike were disappointed that the protein sequence of pyrin/marenostrin did not immediately suggest clues as to the molecular etiology of FMF. Though we are still far from a complete understanding of the function of pyrin/marenostrin at the cellular level, continued study of this intriguing protein is revealing new molecular details about inflammatory processes; the emerging information is relevant not only to FMF, but to innate immunity in general. Data from several laboratories demonstrate that pyrin/marenostrin is intimately connected to three important cellular pathways: apoptosis, cytoskeletal signaling and cytokine secretion. These connections occur, at least in part, through the direct interaction of the pyrin/marenostrin protein with two cytosolic protein adaptors: ASC (also called PyCARD or Tms1) and PSTPIP (also called CD2BP1). Here, we review the more recent literature regarding the molecular and cellular biology of pyrin/marenostrin and pinpoint open questions for future study.</p>","PeriodicalId":86954,"journal":{"name":"Current drug targets.

It metabolised by liver and only small amounts are recovered unchanged in the urine. Really plasma half-life is prolonged in patients with liver or renal failure. Colchicine is able to prevent activation of neutrophils, binding beta-tubulin and making beta-tubulin-colchicine complexes; this way inhibits assembly of microtubules and mitotic spindle formation; moreover its mode of action includes modulation of chemokines, prostanoids production, inhibition of neutrophil and endothelial cell adhesion molecules. The minimal daily dose in adults is 1.0 mg/die, but in children there is not a definite dose. Since in vitro high dosages of colchicine stop mitosis, this drug might interfere with male and female fertility and with children growth, but, according to current guidelines and because of rare side effects of the drug, FMF patients are recommended to take colchicine. Since colchicine treatment is often complicated by frequent gastrointestinal side effects, by our experience, in order to improve colchicine tolerance we recommend: lactose-free diet and treatment of intestinal bacterial overgrowth and/or Hp-infection, assessed by breath tests. Since our data showed that 10-15% of FMF patients seem are non-responders or intolerant to colchicine, today we are working in the design of colchicine analogues which may have lesser toxicities and a larger therapeutic window.</p>","PeriodicalId":86954,"journal":{"name":"Current drug targets.
