obtaining a continuous source of normal cells or dna from a single individual has always been a rate limiting step in biomedical research. availability of lymphoblastoid cell lines (lcls) as a surrogate for isolated or cryopreserved peripheral blood lymphocytes has substantially accelerated the process of biological investigations. lcls can be established by in vitro infection of resting b cell...

A human IgMk monoclonal antibody, 2F7, of predetermined specificity, has been produced by the fusion of human peripheral blood lymphocytes with the nonsecreting mouse myeloma line SP-1. The heterohybridoma has remained stable for over 8 mo, with culture supernatants containing up to 30 micrograms/ml of specific IgM. The antibody has been shown to be capable of inducing a blastogenic response in...

Introduction: Radiotherapy is still one of the main options for cancer treatment but it is in association with damage to normal cells as well as the tumor cells. To reduce the injury in normal cells we have evaluated the effect of 528 hertz sound after X irradiation in peripheral blood lymphocytes. Materials and Methods: in this study, peripheral blood was o...

The cytotoxic host immune response toward autologous human cancer may be regulated by the immunoregulatory network. Here we show that helper T cells, cloned from peripheral blood lymphocytes that were sensitized in vitro against an autologous human malignant paraganglioma, proliferated against and made interleukin 2 when cocultured with the tumor-associated antigen in the presence of autologous...

background , despite numerous studies over a decade, it still remains controversial about the biological effects of rf emf emitted by mobile phone telephony. objective , here we investigated the effect of 900 mhz gsm on the induction of oxidative stress and the level of intracellular reactive oxygen species (ros) in human mononuclear cells, monocytes and lymphocytes as defence system cells. met...
