micrornas (mirnas) are small preserved non-coding rna molecules that regulate gene expression post-transcriptionally by targeting the 3' utr of mrnas for translational repression or degradation. the rising evidence has established the significant role of mirnas within the regulation of immune system and the prevention of autoimmunity. mir-146a has obtained an importance as a modulator of d...

autoimmune diseases have been described as an interesting and poorly understood group of disorders. there are many challenges in the respective scientific societies concerning the nature, causes and the therapeutic approaches of these diseases. in accordance with the evidences the nature and etiology of these disorders is multifactorial and complex but the clearest definition could be expressed...

multiple sclerosis is an autoimmune disease caused by damage to the myelin of the nerve cells in the spinal cord and brain, ms was classified into 4 types including: relasping/remitting (rr) primary/progressive (pp), secondary/progressive (sp), progressive/relapsing (pr). pr ms is one of the severe forms of ms that lead to inflammation associated physical, mental and vision dysfunction. because...

bacterial and viral triggers are suspected agents in the initial etiology of autoimmune diseases. there are some studies on the etiology of autoimmune disorders which have focused on streptococcal infection and a possible relation with microbial heat shock proteins (hsp) which show significant homology with human heat shock proteins. in addition, some serotypes of streptococci cross-react with ...

conclusions thyroid dysfunction was not higher in sle patients compared to healthy individuals. however, anti-tg antibodies were higher in sle patients. it has not yet been established that thyroid function tests should be performed routinely in sle patients. results the mean age of sle patients and controls were 32.16 ± 9.19 and 32.48 ± 9.47 years, respectively (p = 0.821). patients had signif...

idiopathic inflammatory myopathies are a heterogeneous group of muscle disorders characterized by chronic muscle inflammation and progressive muscle weakness. polymyositis (pm), dermatomyositis (dm) and inclusion body myositis (ibm) are the three major subsets based on distinct clinical and histopathological features. since the pathogenesis remains unclear, therapeutic approaches actually compr...

tyrosinase has been recognized as a major autoantign in human vitiligo. here we have shown that experimental autoimmune vitiligo can be induced by intradermal injection of mushroom tyrosinase emulsified in complete freund’s adjuvant in c57bl/6 mice. the onse of vitiligo was characterized by hair hypopigmentation and total melanocyte depletion in the basal layer of the epidermis. our results con...

phage-displayed random peptide libraries (rpl) provide a powerful technique for identification, structural and functional analysis of ligands for many different target molecules, including, antibodies, receptors or other proteins. this strategy has been verified to be an effective tool for research in immunology and successfully has been used to determine the target sequence for monoclonal and ...
