TLDR
The reconstitution of the immune response of lethally irradiated mice to human gamma-globulin is dependent on the synergistic action of bone marrow with thymus cells, but neither bone marrow nor thymUS cells from unresponsive donors are capable of demonstrating synergism in combination with their normal counterpart.Abstract:
The reconstitution of the immune response of lethally irradiated mice to human γ-globulin is dependent on the synergistic action of bone marrow with thymus cells. Immunologic unresponsiveness appears to involve a functional defect at each of these cellular levels, inasmuch as neither bone marrow nor thymus cells from unresponsive donors are capable of demonstrating synergism in combination with their normal counterpart.read more

CELLULAR PARAMETERS OF THE TOLERANT STATE INDUCED TO HUMAN γ GLOBULIN IN MICE AND OF ITS MODULATION BY BACTERIAL LIPOPOLYSACCHARIDES
TL;DR: The cellular parameters of a tolerant state in mice to human γ globulin and its modulation by bacterial lipopolysaccharides are discussed and an ontogenetic basis for self tolerance could be viewed as occurring at a stage in the course of lymphoid cell differentiation when a negative response is the only consequence that can result from a specific interaction between lymphocyte and antigen.

TL;DR: The factors that contribute to this immunogenicity and possible ways to overcome it are reviewed.

Lymphocyte trapping in tolerant mice.
TL;DR: One of the earliest events in the initiation of humoral immune responses is the recruitment of peripheral lymphocytes6–11, and the kinetics of recruitment in tolerant animals is investigated.

The continuing carrier problem.

TL;DR: It is clear that: 1) immunoglobulins are heterogeneous in their capacity to bind molecular patterns (antigens) foreign to the body, 2) lymphocytes bind antigens with the aid of surface receptor molecules, and 3) specificity is determined prior to antigen contact.

TL;DR: The results were considered to support the concept that memory resides in the T cell population and that collaboration between T and B cells is necessary for an optimal secondary antibody response.

TL;DR: Suspensions containing normal thymus, spleen, or marrow cells were injected into irradiated syngeneic mice which were subsequently given antigen and mice receiving both marrow and thymUS cells produced more centers of hemolytic activity in their spleens than mice receiving cells of either type alone.

Antibody formation in vitro.
TL;DR: The results are discussed in terms of a possible mechanism of antibody production in which an RNAse-sensitive substance resulting from the interaction of macrophages and antigen is capable of stimulating antibody synthesis in lymphocytic cells.

TL;DR: The method is simple and sensitive and the results mimic the kinetics of the response that is seen in in vivo assays of serum antibody.
