Background: Tumor associated antigens can be viably used to enhance host immune response. Objectives: The immunomodulatory effect of biogenic selenium nanoparticles (SeNPs) was compared between treated and untreated mice with crude antigens of 4T1 cells. Materials and Methods: Female inbred BALB/c mice (60) were injected by cancinogenic 4T1 cells causing breast cancer. After 10 days, all tumor ...
the immune response to hepatitis b surface antigen (hbsag) is influenced by several factors, of which hla antigens and balanced secretion of th1/th2 cytokines play important roles. the aim of this study was to evaluate the influence of hla antigens on cytokine secretion by hbsag-stimulated peripheral blood mononuclear cells (pbmc) from healthy neonates vaccinated with recombinant hbsag. pbmcs w...
selective iga deficiency (igad) (serum iga concentration of pcr was used to type hla b, dr, and dq alleles in 29 iranian individuals with igad and 299 swedish individuals with igad. the results indicate a strong association with the hla b14, dr1 alleles in iranian subjects and hla b8, b12, b13, b14, b40, dr1, dr3, dr7, dq2 and dq5 alleles in swedish subjects. differences in hla association of i...
hiv infection by maternal transmission is increasing in the world due to the increase in infected women who are not receiving appropriate antiretroviral therapy. prognosis of hiv infection in children is poor because the newborn has an immature immune system. early diagnosis and therapy are needed to avoid the development of aids. new therapies are becoming available but prevention of infection...
Abstract A cognate antigen engagement of TCR induces a conformation change in the CD3 complex (CD3Δc) that is required for productive T cell activation. CD3Δc fails when TCRs interact with poorly immunogenic antigens, like many tumor-associated-antigens (TAAs), which do not active cells. Anti-CD3 monovalent Fab fragments (Mono-Fabs) bound to mimic CD3Δc, producing “co-potentiation” associated w...
background: sand fly saliva helps parasite establishment and induce immune responses in vertebrate hosts. in the current study, we investigated the modulation of phlebotomus papatasi salivary gland antigen expression by seasonal and biological factors. methods: sand flies were grouped according to physiological stages such as unfed, fed, semi-gravid, gravid, parous, nulliparous, infected or no...
conclusions chaharmahal and bakhtiari province could be categorized as a low endemic region for hepatitis b infection, with a seroprevalence similar to that in other provinces of western iran. vaccination seems to influence its decrease, especially in adolescents and youth. more surveillance and attention to risk factors are suggested to identify high-risk groups and to implement vaccination. r...
transforming growth factor atpha (tgf-a), parathyroid hormone-tike proteins (pthlp) and oncogene p53 proteins have all been demonstrated in a variety of human tumors anil have been implicated as causes of tumor cell aggressiveness. the present study determined the existence of these peptides and their immunohistochemicat profiles in ameloblastomas. odontogenic keratocysts and dentigerous cysts ...
abstract objective the history of the studies on blood groups dates back to early 20th century. more than 600 antigenic structures were detected among 29 blood groups. however, abo and rh antigenic structures were taken into consideration in transfusion medicine. frequency of the blood groups in a community helps the individuals in need and blood bank employees, which could be related to some d...
indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of h. contortus. plate elisa was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. indirect plate elisa was able to demonstrate...
