    Notes: Oral tolerance is a T-cell mediated phenomenon defined by a refractoriness to parenteral immunization with a protein that was first contacted by oral route. However, the authors have shown that the injection of a tolerated protein is not neutral for the immune system. In mice made tolerant to KLH by gavage, co-immunization with KLH and DNP-Ova blocks anti-DNP antibody formation. Anti-DNP antibody formation resulting from immunization with DNP-Ova can also be blocked by co-immunization with a dietary protein (zein) or a self component (fibrinogen). The inhibitory effects resulting from immunization with a tolerated protein, designated indirect effects, do not affect the induction of oral tolerance to another protein. These results support the hypothesis that active mechanism are involved in the maintenance of tolerance.

    Immaturity, Ageing and Oral Tolerance (1997)

    Notes: Founding studies of cellular immunology emphasized that tolerance to allografts could only be achieved early in the embryonic or neonatal period, suggesting that the establishment of self-tolerance, a main event in the organization of the immune system, would necessarily take place in immature hosts. Contradicting these ideas, oral tolerance is a common, daily phenomenon, easily achieved by a physiological route in adult immunocompetent animals. Furthermore, there is solid evidence that, after the neonatal period, the susceptibility to oral tolerance induction also wanes and that it may be restored by adoptive transfer of cells from young hosts. These findings are briefly reviewed here to emphasize that immunological activity is a continuous and ongoing epigenesis extending throughout the entire life of the organism, far beyond the early phases of ontogenesis.

    Immunological Induction of Flavour Aversion in Mice. II. Passive/Adoptive Transfer and Pharmacological Inhibition (1997)

    Notes: Mice immunized with ovalbumin develop a strong aversion to ingesting sweetened egg white dilutions or ovalbumin solutions. In immunized animals, gavage or voluntary ingestion of ovalbumin triggers an increase of vascular permeability in the intestine; pretreatment with a mixture of histamine and serotonin antagonists blocked this reaction, but not the aversion; dexamethasone inhibited both the aversion and the increase in permeability. The aversion was transferred to normal recipient mice with high-titre anti-Ova sera obtained with complete Freund’s adjuvant, but not with lower-titre serum pools of mice immunized with the help of Al(OH)3 adjuvant. However, the aversion was also (adoptively) transferred with whole spleen cells from immune donors. This later condition is inefficient to transfer the formation of high titres of specific antibodies.

    Indirect Effects of Oral Tolerance Cannot be Ascribed to Bystander Suppression (1997)

    Notes: The addition of tolerated antigens to immunizing doses of unrelated antigens blocks antibody responses to these unrelated antigens. This inhibition, which the authors have called the indirect effects of tolerated antigens, occurs even when the mixture of proteins is injected as soon as 24 h after the oral tolerance induction. The indirect effects also do not require the simultaneous injection of the two proteins: they are still present 72 h after an injection of Ova in Ova tolerant mice, but do not occur if the unrelated protein is injected 24 h before the tolerated protein. In addition, indirect effects do not block secondary responses to unrelated proteins if the primary immunization is made in the absence of the tolerated protein. These results cannot be explained by innocent bystander suppression, which is believed to result from the action of suppressive cytokines released by specific tolerant lymphocytes upon unrelated lymphocytes that would otherwise respond to the second, non-tolerated antigen. Indirect effects may be better understood in terms of network models.

    Anti-IL-10 Treatment Does Not Block Either the Induction or the Maintenance of Orally Induced Tolerance to Ova (1995)

    Notes: Herein, the role of IL-10 in the induction and maintenance of oral tolerance was evaluated. The results show that: (1) mice treated with MoAb anti-IL-10 are permissive to the induction of oral tolerance to OVA; (2) anti-IL-10 treatment did not reverse the in vitro blocking of T cell proliferative response found in orally-tolerized mice; and (3) orally-induced tolerance could not be broken by anti-IL-10 treatment. Taken together, these results suggest that IL-10 is not a fundamental cytokine for the establishment and maintenance of oral tolerance.

    Indirect Effects of Oral Tolerance in Mice (1994)

    Notes: Anti-DNP antibody formation resulting from intraperitoneal (i. p.) immunization with DNP-KLH may be blocked by simultaneous (i. p.) injection of DNP-Ova or native Ova in mice orally tolerant to Ova, but not in normal mice. In Ova-tolerant mice the inhibition of anti-DNP antibody formation also occurred when DNP-Ova and DNP-KLH were given by separate routes of immunization: subcutaneous (s. c.) and i. p. A second exposure to Ova by gastric intubation (gavage) or intravenous administration simultaneously with i. p. immunization with DNP-KLH failed to inhibit anti-DNP antibody formation. There was inhibition of responses to DNP-KLH i. p. by DNP-Ova given 24 h before, but not 24 h after, and in the Ova-tolerant mice, addition of DNP-Ova only to the primary immunization with DNP-KLH inhibited secondary and tertiary responses to DNP-KLH in the absence of further exposures lo DNP-Ova.These results suggest that the indirect effects of parenteral exposure of tolerant mice to the tolerated immunogen may inhibit unrelated immune responses. This inhibition is not due to ‘innocent bystanding’ suppression, i, e., to inhibitory cytokines provided locally by specific suppressor lymphocytes; it may derive from more durable perturbations of immune system.
