the mrna expression of growth hormone (gh) gene in early development stages of siberian sturgeon was investigated using rt-pcr method. samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. ribosomal protein l6 (rpl6) transcripts were used as the internal standard during quantification of gh mrna expression. the results showed that the gh mr...

background: recently, reports have indicated a role for the membrane form of toll-like receptor 2 (tlr2) in asthma pathogenesis. in this study we examined soluble tlr2 levels in serum and sputum of asthmatic and healthy subjects. methods: serum and sputum samples were obtained from 33 asthmatic and 19 healthy subjects. the asthmatics were classified into four groups according to the global init...

abstract objective: the previous studies indicated that the tlrs especially toll-like receptor 4) tlr4 (are involved in the process of diabetes. the aim of the present research was to investigate the time course expression pattern of tlr4-a main component of innate immune system- in mrna levels in the heart tissue of diabetic male wistar rats. materials and methods: in this research, adult wist...

background: because of the strong immunologic responses of surface protein tasp in theileria annu­lata infected host, we tried to characterize this protein in a t. annulata isolate from iran. methods: the rna prepared from t. annulata infected cells was used to produce smart-ds-cdna. the double strand cdna was then amplified with primers derived from tasp mrna se­quences. the pcr product was cl...

bakground: multiple sclerosis (ms) is a cd4+ t cell-mediated autoimmune disease affecting the central nervous system (cns). it was previously believed that th1 cells were pathogenic t cells in experimental autoimmune encephalomyelitis (eae). however, the functional role of th1 cells in eae has been reconsidered upon the discovery of il-17- producing t cells which are consider as dominant effect...
