The effect of transplantation of bone marrow or lymphocytes on the resistance of irradiated animals to diphtheria toxin
Two experiments were staged on guinea pigs to investigate the effect produced by transplantation of the cells of homologous bone marrow and lymph nodes, in order to restore the natural resistance of the animal...

Article
Antitoxin formation by cells transplanted into an irradiated animal
An inquiry was made into some aspects of antitoxic immunity by using the cellular transplantation method. Guinea pigs and rabbits were used for the experiment. The recipients were irradiated: guinea pigs with ...

Article
Aggregated immunoglobulins as antigen-binding receptors of immune lymphocytes
At the peak of the primary immune response to sheep's red cells rosette-forming cells, effectively inactivated by antibodies against aggregated mouse immunoglobulin and by a polyA:polyU complex, appear in the ...

Article
Aggregated immunoglobulins on the surface of rapidly dividing antigen-binding lymphocytes
In the primary immune response of mice to sheep's red cells rosette-forming cells with aggregated immunoglobulins on their surface appear in the fraction of small lymphocytes in the spleen. These cells effecti...

Homocytotropic IgG1 and IgE antibodies and passive cutaneous anaphylaxis in mice of various strains
Experiments on mice of nine strains with different H-2 genotypes showed that a predisposition to anaphylaxis at the stage of formation of IgG1 and IgE antibodies and sensitivity of the skin to passive anaphylaxis...

Article
Replacement of immunoglobulin receptors by lymphocytes contained in the mouse spleen at the peak of the primary immune response
Spleen cells obtained from mice on the fifth day after injection of sheep's red cells (SRBC) irreversibly lose 50% of their surface immunoglobulin receptors during culture in vitro for 4 h. On incubation of sp...

Article
Preparation of a mouse antiserum against isologous aggregated immunoglobulins and the study of its action on rosette-forming cells
A method of obtaining antiserum against isologous aggregated mouse immunoglobulins (MAAS) is described. This serum blocks the antigen-binding receptors of immune rosette-forming cells in vitro. MAAS was inject...

Article
Migrating ability of tumor cells treated with immune sera
The action of antitumor sera (ATS) on the adhesive properties of L cells and of Ehrlich's ascites carcinoma cells was studied. The ability of the tumor cells to adhere to plastic and glass and to form rosettes...

Article
Effect of stem cell inhibition factor and macrophage micration inhibition factor on exocolonization and migration of mouse spleen cells
Hematopoietic stem cell inhibition factor (SCIF), liberated by lymphocytes treated with antilymphocytic globulin, causes inhibition of migration of the spleen cells of intact mice. The degree of inhibition of ...

Article
Action of mouse antiserum against isologous aggregated immunoglobulins on transplantation and antitumor immunity
Mouse antiserum against isologous heat-aggregated immunoglobulins (MAAS), on repeated injection into animals, prolonged the survival of skin allografts, facilitated the development of Moloney sarcoma, reduced ...

Comparative study of Rosette- and plaque-formation in rats infected withMycoplasma arthritidis andAcholeplasma laidlawii
Mycoplasma arthritidis was shown to inhibit rosette and plaque formation in rats infected with this species of mycoplasma. By the 15th day the immune response in the control and experimental groups was equal aga...

Article
Endogenous colony formation in mice under the influence of Mycoplasma arthritidis and Rauscher leukemia virus
Mycoplasma arthritidis was shown not to affect endogenous colony formation in lethally irradiated BALB/c mice. The number of endogenous foci in mice irradiated in sublethal doses and infected withM. arthritidis ...

Immunologic reactivity of (C57BL/6 × A/Sn)F1 mice in mixed Mycoplasma-virus infection
Mixed infection of hybrid mice, highly resistant to Rauscher virus, with this virus andMycoplasma arthritidis was accompanied by progressive inhibition of populations of splenic rosetteforming (REC) and plaque-fo...
