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.

Self/nonself discrimination among immunoregulatory (CD4) T cells.

TL;DR: This review covers work on immunological tolerance from 1962 up to the present, focusing on the Th, CD4+ compartment of the immune system, and the principle mechanism of tolerance is identified as deletion, occurring centrally and in the periphery.

Immunological tolerance in the amphibian xenopus laevis (daudin)

TL;DR: The implication of these results is that immunomaturity of the donor and host is important in the induction of transplantation tolerance but that other· factors must also be involved.

Structural control of immunogenicity. 3. Preparation for and elicitation of anamnestic antibody responses by oligo- and poly-lysines and their DNP derivatives.

TL;DR: It is shown here that 1-e-D NP-tetra-L-lysine is not effective, or only marginally effective, in preparing PLL+ guinea-pigs for secondary anti-DNP responses to DNP-poly-L

Tolerance and Autoimmunity: B Cells

TL;DR: Tolerance and immunity are no longer considered to be totally discrete entities, but rather the poles of a continuum of immune responsiveness, the former appropriate to self- and the latter to foreign antigens.

Cell to cell interaction in the immune response. II. The source of hemolysin-forming cells in irradiated mice given bone marrow and thymus or thoracic duct lymphocytes.

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: It was found that both adherent and nonadherent cells were necessary for the induction of antibody formation to sheep red blood cells in vitro.

Thymus-Marrow Cell Combinations. Synergism in Antibody Production.∗:

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.

A Modification of the Hemolytic Plaque Assay for Use with Protein Antigens

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.
