In vitro transfer of cellular immunity in experimental allergic orchitis by means of immune RNA.

Ribonucleic acid (RNA) extracts were obtained from lymph nodes of guinea-pigs that had previously been immunized with a purified testicular antigen emulsified in Freund's complete adjuvant. The RNA extracts were incubated with normal guinea-pig peritoneal exudate cells (NGP-PEC). After treatment, the NGP-PEC cells showed specific inhibition of migration when tested with the specific antigen. No inhibition of migration was observed when cells were tested with an unrelated antigen or when the cells were incubated with RNA obtained from animals immunized with adjuvant alone. Failure of inhibition of migration was also observed when the 'immune' RNA was degraded with RNAse. The appearance of this I-RNA in the immunized guinea-pigs correlates with the appearance of delayed hypersensitivity in vivo.

[Absence of cutaneous phenomena of delayed hypersensitivity in the use of zymosan as adjuvant in comparison with Freund's complete adjuvant in autoimmune experimental orchitis].

In previous researches some of the Authors proved that Zymosan acts as adjuvant in determining the experimental autoimmune aspermatogenesis, in absence of skin reactivity of delayed type. The aim of the present investigations was to ascertain if Zymosan possess some components analogous to those of mycobacteria, which can be considered responsible in determining hypersensitivity reactions of delayed type. The results, obtained also in cross experiments, don't confirm this hypothesis.
