Abstract Self antigen-specific T cells are prevalent in the mature adaptive immune repertoire. At steady state, these regulated by various mechanisms of peripheral tolerance. Characterizing activation self during inflammation may shed crucial insights into pathogenesis autoimmunity. Utilizing an experimental animal model where mice express three cell epitopes (2W, gp66, and OVA) a tissue restri...
cystic hydatid disease (hydatidosis) is the most serious tape-worm infection prevalent in the cattle and sheep raising area of the world. hydatidosis in man (as an accidental host) caused by infection with the ova containing larval stage of echinococcus spp. in the last decade different techniques have been employed for the serological diagnosis of hydatid disease, such as iha, ifa, elisa, ccle...
background: the study aimed to examine the association between human leukocyte antigen (hla) class ii allele frequencies and breast cancer in iranian women. methods: a total of 100 patients with pathologically proven breast cancer who referred to cancer institute were randomly selected and compared with a group of age matched healthy blood donors (n = 80). hla class ii alleles were determined b...
background: antigen b (agb) is frequently used for immuno-diagnosis of hu-man cystic echinococcosis (ce). echinococcus granulosus agbs show a high degree of genetic variability in different hosts or in different ce endemic areas. the present study aimed to evaluate the genetic polymorphisms of encoding antigen b2 gene (agb2) among different iranian isolates of e. granulosus. methods: a total of...
background :highserum level of cancer antigen 15.3 (ca15.3) has been reported in some malignant and nonmalignant conditions including thalassemia major which could have been resulted from ineffective erythropoiesis. we aimed to evaluate the serum level of ca15.3 in carriers of beta-thalassemia by comparing them with cancer patients and healthy individuals. methods : this cross-sectional study...
background:non-melanoma skin cancer (nmsc), the most prevalent types being squamous cell carcinoma (scc) and basal cell carcinoma (bcc), is the most common type of malignancy in human beings. these neoplasms are more frequent in the elderly and fair skinned people and mainly occur on sun-exposed sites of the body. ultraviolet b (uvb) has a well-known effect in induction and promotion of growth ...
background: klebseilla pneumoniae causes urinary tract infections, nosocomial pneumonia and intra-abdominal infections. capsular antigens are considered to be the ultimate virulence determinants. among 77 capsular serotypes of k. pneumoniae, serotypes k1 and k2 are the most virulent ones in humans. objectives: we designed a pcr method for detection of capsular serotypes k1 and k2 of k. pneumoni...
background the 30 kda major secretory protein of mycobacterium tuberculosis (antigen 85b) is a primary vaccine candidate. this secreted antigen induces a protective immune response and stimulates the production of ifn-γ in animal models. objectives the aim of this study was cloning and expression of ag 85b of m. tuberculosis in escherichia coli. materials and methods to produce recombinant ag85...
background: hla-g gene contains 15 alleles including a null allele, hla-g*0105n. previous studies have shown that hla-g*0105n does not encode the complete hla-g1 or hla-g5 isoforms but encodes a functional hla-g protein with the ability to in-hibit nk cell cytolysis. thus, although the biological functions of hla-g1 and hla-g5 proteins are abrogated, other isoforms such as hla-g2 can replace th...
hydatid cyst is an important and zoonotic infection caused by cystic stage of echinococcus granulosus. it is a major and economic problem in most areas of the world that livestock are kept such as iran. in this study, a total of 111 buffalo,s sera from center of buffalo sperm preparation (cbsp), orumia (west azarbayjan province, iran, 2003) were examined for the presence of hydatidosis by using...
