Primary tumor immunity in nude mice

Abstract

Tumor implants grew better in radiated or in newborn nu/nu mice than in adult nu/nu controls when, and only when, the tumors were demonstrably immunogenic in normal mice. This result suggests primary immunity. No evidence of immunological memory was found by immunization-challenge type experiments in the nude mice.

Human non-Hodgkin's malignant lymphomas serially transplanted in nude mice conditioned with whole-body irradiation

“…It is often said that established nude mouse lines tend to maintain the original histology and function compared to 'in vitro' cell lines because immunological reactivity toward transplanted tumours is too weak to induce the phenotypic and genotypic changes (Prehn & Outzen, 1977;Thomson et al, 1981). This seems to be the case with our nude mouse tumours.…”

Comparative abilities of athymic nude mice and severe combined immune deficient (SCID) mice to accept transplants of induced rat mammary carcinomas: Enhanced transplantation efficiency of those rat mammary carcinomas that have elevated expression of neu oncogene

“…Irradiation of athymic nude mice has been reported to enhance transplantation of tumor tissue (Prehn and Outzen, 1977;Ohsugi et al, 1980;Watanabe et aL, 1980).…”

A prospective test for human tumour rejection antigens?

“…

The lack of a test to measure reliably the presence or absence of tumour-associated rejection antigens in humans recently prompted Prehn (1977) to suggest a different type of bioassay. It has become increasingly apparent that allogeneic or xenogeneic tumours do not, in general, grow as well when transplanted into athymic nude mice as when transplanted into the strain of origin.

…”

“…This is so in spite of the fact that the strain of origin possesses a normal immunological mechanism while the nude mouse cannot reject an allograft of normal tissue. Prehn and Outzen (1977) have demonstrated that allogeneic and animal tumours grow better in nude mice if the animals are X-irradiated. It is probable that X-irradiation would also facilitate the growth of human tumours in nude mice.…”
