Lymphocyte antibody interaction in cytotoxicity against human transitional cell carcinoma.

The interaction of antibodies and lymphocytes in their immune reaction against human transitional cell carcinomas was studied using the in vitro microcytotoxicity assay. A non-complement dependent, IgG antibody was detected in the serum of occasional transitional cell carcinoma patients, which induced cytotoxicity against transitional cell carcinoma target cells by lymphocytes from donors with and without transitional cell carcinoma. The observation that lymphocytes from transitional cell carcinoma donors were more sensitive to activation by this anti-transitional cell carcinoma, lymphocyte dependent antibody is compatible with the hypothesis that the surface of lymphocytes from some transitional cell carcinoma donors is coated in vivo with an anti-transitional cell carcinoma lymphocyte dependent antibody and that this antibody may be a significant factor in immunity to transitional cell carcinomas of the urinary tract.

Concentration of Rous sarcoma virus from tissue culture fluids with polyethylene glycol.

Concentration of Rous sarcoma virus from tissue culture fluids with polyethylene glycol, with and without NaCl or dextran sulfate, resulted in significant and highly variable losses caused by entrapment of virus particles in proteinaceous debris. Treatment of concentrated preparations with Pronase greatly enhanced the recovery of virions. Maximum recovery of virus particles was obtained by the addition of 8% polyethylene glycol and 0.4 M NaCl to tissue culture fluids, followed by Pronase treatment of the concentrated virus preparations.

Isolation of RNA virus from papillary tumors of the human renal pelvis.

Virus particles were detected by electron microscopy in three papillary cancers of the human renal pelvis. Similar particles were seen in cells from all three tumors in primary culture. An RNA virus was isolated from these tumors. The serum of tumor patients contains neutralizing antibodies against virus isolated from two of the tumors. Initial studies suggest that this agent is not a known human RNA virus.

Technique for cultivation of transitional epithelium from mammalian urinary bladder.

A technique for initiating cultures of epithelial (urothelial) cells from mammalian urinary bladder has been described. Urothelial cells obtained by this method have been used to support replication of viruses and as controls for immunological, biochemical, chromosome, and electron microscopy studies. Both light and electron microscopic studies of cultured cells suggest that they are epithelial and not a mixed culture.
