background: there are only a very small number of reports which discuss subtype, sex distribution, clinical features and laboratory characteristics of autoimmune hepatitis in children. the aim of this study was both to define the clinical features, biochemical and histological findings and also to determine the age and sex related distribution of autoimmune hepatitis (aih). materials and method...

recent developments in medicine have given us a better insight into a group of disorders known as autoimmune diseases. in particular, advances have occurred in our understanding of the autoimmune inner ear disease (aied). in this article, the authors review the different postulated theories in the pathogenesis of this disease. the clinical presentation, the available para-clinical diagnostic to...

background: interleukin-27 is a heterodimeric cytokine belonging to il-12 and il-23 families, secreted  by antigen presenting cells( apcs ) .the il-27 is composed of 2 subunits: epstein-barr virus induced gene 3 (ebi3) and p28. il-27 is an anti-inflammatory cytokine which has an inhibitory effect on th17 population and suppress the il-17 expression. it is suggested that il-27 could be a potent ...

inflammatory bowel diseases are one of the important reasons of the referral to gi practitioners in our country and ulcerative colitis is the more frequent type of these disease in iran. in this study 200 cases of ulcerative colitis, which has been referred to imam khomeini hospital during that last 5 year, were studied. data was collected using the patient's records and face to face inter...

about 3 decades ago cd6 identified as one of the first antigens expresses on the majority of t cells and a subset of b cells. cd6 regulates cellular adhesion migration across the endothelial and epithelial cells. in recent years researches indicate its role in pathogenesis of autoimmune diseases. many researches have been done in recent years to block cd6 by cd6 mono clonal antibodies, ior-t1 a...

background: infectious agents have been suspected as a triggering factor for development of autoimmune thyroid disease (atd). some reports from western countries have suggested association between helicobacter pylori (hp) infection and atd. objective: to investigate the association of atd with cag a seropositivity in a population with high rate and early age of onset of hp infection. methods: i...

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...

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...

multiple sclerosis (ms) is an autoimmune disease in which auto-reactive t cells react with self-antigens expressed in the central nervous system (cns). the main cause of ms is unknown. nonetheless, the most probable theory is based on molecular mimicry, which suggests that some infections can activate t cells against brain auto-antigens like myelin proteolipid protein (plp) and initiate the dis...

multiple sclerosis (ms) is an autoimmune disease of the central nervous system associated to myelin loss and neurodegeneration. clinically patients suffer from diverse symptoms and face the risk to become wheelchair-bound. at the moment ms is incurable, thus there is an unmet need for therapeutic options.
