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

Immune tolerance induction for the eradication of inhibitors in patients with hemophilia A.
TL;DR: A systematic review of published reports on ITI regimens, data from registries capturing response rates and predictors of success, and reports of adjunctive treatments used to enhance ITI therapy finds many issues remain unresolved, chief among them optimal dose and dosing regimen, choice of FVIII product, and the role of adj unctive therapy.

Mechanism of activation and tolerance induction in b lymphocytes.
TL;DR: Three current and fundamentally different models of B Ijmiphocyte activation are discussed, with emphasis on how each explains the mechanism involved in the activation of B lymphocytes in these two responses differs.

Introduction: Antigen Recognizing and Processing Cells
TL;DR: “Antigen binding” and “antigen processing” cells are discussed, which may potentially comprise all cells capable of phagocytosis or pinocytotic.

TL;DR: Analyses of the results of tissue typing in renal allografting indicate the benefit of histocompatibility between recipient and donor, but the probability of finding a fully compatible donor recipient pair will diminish.

D-Aminosäuren-substituierte Peptidepitope induzierten T-Zell-Toleranz in vivo
TL;DR: In this article, the Induktion spezifischer, immunologischer T-Zelltoleranz als therapeutische Strategie bei Autoimmunerkrankungen im Mausmodell unter-sucht.

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.

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.
Journal ArticleDOI
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.
