The simultaneous injection of 4 × 108 sheep erythrocytes and 3 × 109 killed cells of Bordetella pertussis effects an accelerated and prolonged multiplication of antibody-forming spleen cells if compared with mice immunized with the erythrocyte antigen only. If mice of both groups are given a second injection of 4 × 108 sheep erythrocytes 6 weeks later, the numbers of indirect plaque-forming cells are markedly increased in pertussis-treated mice. This is connected with enhanced 7 S serum hemolysin titers. The conclusion is drawn that an initial injection of B. pertussis prepares the lymphoid tissues of mice for the secondary immune response.

In this study we determined at both the cellular and humoral level whether or not the primary immune response of mice can be significantly enhanced by administration of a bacterial adjuvant after the primary immunization with sheep erythrocytes. As compared to the immunization of mice with 8 × 106 sheep erythrocytes alone, the simultaneous injection of 3 × 109Bordetella pertussis cells and 8 × 106 sheep erythrocytes resulted in an accelerated and prolonged multiplication of hemolysin-forming spleen cells. The adjuvant effect was also documented by increased production of serum hemolysins. When the bacterial adjuvant was given 6, 12, or 24 h after the primary antigenic stimulus, however, neither increased plaque counts nor enhanced serum hemolysin titers were detectable. These findings agree with the concept that B. pertussis cells cause multiplication of antigen-sensitive target cells or affect the initial stages of differentiation of these cells.

The direct and indirect plaque technique for the detection of antibody-forming cells against sheep erythrocytes was utilized for the investigation of a number of biological parameters of the primary and secondary immune response on a cellular level. The sequential pattern of 19S followed by 7S antibody formation was elicited in the primary response after a latent period of at least 1–2 days and 2–3 days respectively. The secondary response initiated 140 days after primary immunization, in contrast, was characterized by the simultaneous appearance of 19S and 7S antibody-forming cells after an observed latent period of 2–3 days. The cellular dynamics of the recruitment phase of the respective immunoglobulins in the primary and secondary response was interpreted as evidence for the derivation of the two classes of immunoglobulins from separate progenitors. The 19S antibody-forming cells were derived predominantly by a process of transformation and maturation and 7S antibody formers by a process of cellular division with a doubling time of about 12 hr. The draining lymph node exhibited maximal immunological reactivity due to its capacity to retain the particulate antigen. This capacity was considerably enhanced in the sensitized draining lymph node. Minimal cellular activity was also noted in distal lymphoid tissues which included the thymus. Focal cellular activity was observed in the draining lymph node for 60 days after immunization. Subsequently, very low level plaque-forming cellular activity was observed in association with persistence of maximal antibody activity. The appearance at 120 days of a generalized peak of cellular activity in lymphoid tissues throughout the host was considered an explanation for this discrepancy. The change in distribution of cellular antibody-forming activity, from a local to a generalized lymphatic response during the late phase of the immune response, implied a fundamental alteration in homeostatic mechanisms associated with maintenance of immune reactivity. Further manifestations of such an alteration were indicated by the appearance of 2-ME-sensitive 7S antibody nearly 3 months after primary intradermal immunization, which in the ensuing 5 months was associated with, and inversely related to, two major fluctuations in 2-ME-resistant 7S antibody. Evidence for the existence of immunological memory in the 19S system was not established in the present work. 19S anamnesis, for which evidence was derived from measurements of circulating antibody levels, was interpreted from cellular studies as the result of the substantial activity of previously uncommitted 19S lymphoid cells in distal lymphoid tissue associated with previously committed 19S cells contained in the draining lymph node.

In this series of papers it has been shown that the immune response of mice to sheep erythrocytes requires the participation of two classes of lymphoid cells. Thymus-derived cells initially react with antigen and then interact with another class of cells, the antibody-forming cell precursors, to cause their differentiation to antibody-forming cells. Antilymphocyte globulin depressed the ability of mice to respond to sheep erythrocytes. This effect was more marked when the antigen was injected intraperitoneally than intravenously, and occurred only when the antilymphocyte globulin was given before or simultaneously with antigen. Injection of thymus cells restored to near normal the ability to respond to an intravenous injection of sheep erythrocytes. Spleen cells from antilymphocyte globulin-treated mice gave a weak adoptive immune response in irradiated recipients. The addition of thymus cells however enabled a response similar to that given by normal spleen cells. When thymectomized irradiated recipients were used, normal spleen cells continued to give a higher response to a challenge of sheep erythrocytes at 2 and 4 wk postirradiation than did spleen cells from ALG-treated donors. This result is more consistent with the notion that thymus-derived target cells are eliminated, rather than temporarily inactivated, by antilymphocyte globulin. These findings suggest that, in vivo, antilymphocyte globulin acts selectively on the thymus-derived antigen-reactive cells.

We carried out a study on the adjuvant effect of Bordetella pertussis vaccine on the primary and secondary immune responses of the mouse to sheep erythrocytes, quantitating antibody-producing spleen cells and serum antibody. The simultaneous injection of sheep erythrocytes and B. pertussis , when compared to immunization with sheep red blood cells alone, resulted in an increased and prolonged multiplication of antibody-forming spleen cells. The adjuvant effect was also documented by increased production of serum hemolysins and agglutinins. Further, B. pertussis enhanced the priming effect of the antigen for the secondary response. However, when the bacterial adjuvant was given together with a second antigenic stimulus 41 days after the primary immunization, the peak values of direct and indirect plaque-forming spleen cells did not differ from the corresponding control animals further inoculated with sheep erythrocytes alone. Nonetheless, the influence of the bacterial adjuvant was still expressed by the delayed decrease of the numbers of plaque-forming spleen cells. On the basis of the X-Y-Z scheme it is suggested that B. pertussis cells as adjuvant enhance the multiplication of antigen-sensitive X cells or affect the initial stages of differentiation of these cells. This effect of the pertussis vaccine can be distinguished from a general proliferative action on other cells.

Mouse spleen cells were found to associate in cell clusters during the primary immune response to sheep erythrocytes in vitro. About 10% of the cell clusters had the following unique properties; (a) they contained most, if not all, antibody-forming cells, (b) they contained only cells forming antibody to one antigen when cell cultures were immunized with two antigens, (c) the cells in clusters reaggregated specifically after dispersion, and (d) the specific reaggregation of clusters appeared to be blocked by antibody to the antigen. The integrity of cell clusters was required for the proliferation of antibody-forming cells, and prevention of clustering by mechanical means or by excess antibody blocked the immune response. Antibody and antigenic determinants on the surfaces of cells probably provide the basis for interaction. The unique microenvironment of cell clusters was essential for the primary immune response in vitro.
