Specific Antibodies Reacting with SV40 Large T Antigen Mimotopes in Serum Samples of Healthy Subjects.

Simian Virus 40, experimentally assayed in vitro in different animal and human cells and in vivo in rodents, was classified as a small DNA tumor virus. In previous studies, many groups identified Simian Virus 40 sequences in healthy individuals and cancer patients using PCR techniques, whereas others failed to detect the viral sequences in human specimens. These conflicting results prompted us to develop a novel indirect ELISA with synthetic peptides, mimicking Simian Virus 40 capsid viral protein antigens, named mimotopes.

Immunologic evidence of a strong association between non-Hodgkin lymphoma and simian virus 40.

Background: Non-Hodgkin lymphoma (NHL), the most common cancer of the lymphatic system, is of unknown etiology. The identification of etiologic factors in the onset of NHL is a key event that could facilitate the prevention and cure of this malignancy. Simian virus 40 (SV40) has been considered an oncogenic agent in the onset/progression of NHL.

Serum antibodies from epileptic patients react, at high prevalence, with simian virus 40 mimotopes.

Background And Purpose: It has been demonstrated that inflammation may contribute to epileptogenesis and cause neuronal injury in epilepsy. In this study, the prevalence of antibodies to simian virus 40 (SV40), a kidney and neurotropic polyomavirus, was investigated in serum samples from 88 epileptic children/adolescents/young adults.

Methods: Serum antibodies reacting to specific SV40 peptides were analysed by indirect enzyme-linked immunosorbent assay.

Significant association between human osteosarcoma and simian virus 40.

Background: Simian virus 40 (SV40) has been considered to be an oncogenic viral agent in the development of osteosarcoma (OS), which to the authors' knowledge continues to be of unknown etiology.

Methods: In the current study, serum samples from patients with OS were investigated with an indirect enzyme-linked immunoadsorbent assay (ELISA) to test for the presence of immunoglobulin G antibodies, which react with SV40 antigens. In ELISA, SV40 antigens were represented by 2 synthetic polypeptides that mimic epitopes of the viral capsid proteins 1 to 3.

Serologic investigation of undifferentiated nasopharyngeal carcinoma and simian virus 40 infection.

Background: The association between undifferentiated nasopharyngeal carcinoma (NPC) and Epstein-Barr virus (EBV) is well established. Nevertheless, available evidence suggests that other cofactors are required for the development of undifferentiated NPC. Several investigations reported simian virus 40 (SV40) footprints in human tumors of different histotypes.
