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.

A Theory of Self- Nonself Discrimination.

TL;DR: The foregoing requirements provide an explanation for self-nonself discrimination, which involves a specific deletion in the activity of both the humoral- and the carrier-antigen-sensitive cells.

Therapeutic efficacy of multiple intravenous infusions of anti-tumor necrosis factor alpha monoclonal antibody combined with low-dose weekly methotrexate in rheumatoid arthritis.

TL;DR: Multiple infusions of cA2 were effective and well tolerated, with the best results occurring at 3 and 10 mg/kg either alone or in combination with MTX in approximately 60% of patients with active RA despite therapy with low-dose MTX.

Anti-TNF alpha therapy of rheumatoid arthritis: what have we learned?

TL;DR: Clinical investigations in which the activity of TNF alpha in RA patients was blocked with intravenously administered infliximab, a chimeric anti-TNF alpha monoclonal antibody (mAB), has provided evidence that TNF regulates IL-6, IL-8, MCP-1, and VEGF production, recruitment of immune and inflammatory cells into joints, angiogenesis, and reduction of blood levels of matrix metalloproteinases-1 and -3.

TL;DR: The immunosuppressive effect of the presence of thymocytes during the antigen Pretreatment was studied by adoptively transferring the spleen cells of the antigen pretreated mice to thymus-deprived chimeras.

Development of anti-TNF therapy for rheumatoid arthritis

TL;DR: Progress in the characterization of intercellular mediators — proteins that are now known as cytokines — has led to the realization that one cytokine, tumour-necrosis factor (TNF; previously known as TNF-α), has an important role in the pathogenesis of rheumatoid arthritis.
