Guinea pigs were injected in the footpads with either purified diphtheria toxoid or recrystallized egg albumin in Freund adjuvant without mycobacteria. Each guinea pig was then skin-tested only once with the specific antigen and bled for antibody determination. After injection of the sensitizing antigen, a latent period occurred during which neither sensitivity nor circulating antibody could be detected. A period of delayed sensitivity followed wherein circulating antibody could not be discerned and which could be transferred by lymph node cells. Ultimately, the Arthus type sensitivity developed, accompanied by circulating antibody. The duration and severity of reactions to homologous antigens during the last 2 phases varied with the antigen and with the dose. An increase in the sensitizing dose decreased the duration of the delayed type of allergy, a decrease in the dose prolonged the delayed type. Inclusion of mycobacterium in the sensitizing inoculum tended to introduce delayed sensitivity earlier and delay the onset of Arthus type sensitivity. When specific precipitate in antibody excess was included with the toxoid in the sensitizing dose, the onset of the Arthus phase was hastened. When lymph nodes from a large number of sensitized donors were removed during the latter part of the latent period, recipients of the cells showed a delayed type sensitivity.

In the presence of specific antigen, lymph node cells from inbred rats with delayed hypersensitivity to tuberculoprotein, bovine gammaglobulin, and egg albumin produced progressive destruction of monolayers of rat embryo fibroblasts in tissue culture, first apparent at 48 hr and maximal at 72 hr. The effect was specific and did not depend on a genetic difference between the lymph node cells and target cells. It required antigen concentrations equal to or greater than 1.25 µg/ml and lymphocyte: target cell ratios of approximately 10 or 20:1. It could be evaluated both by a plaquing technique and by cell enumeration with an electronic particle counter.

The lymph node cells from all L-glutamic acid and L-tyrosine (GT) responder random-bred guinea pigs were susceptible to lysis by strain 2 anti-strain 13 isoantisera in the presence of complement. These same antisera were cytolytic for lymph node cells of only some of the GT nonresponder animals. However, after absorption with cells, from a nonresponder guinea pig, susceptible to lysis, the anti-strain 13 antisera were no longer able to lyse cells from any GT nonresponder guinea pigs while retaining a large measure of their cytolytic activity for cells of all GT responder guinea pigs. Thus, at least two major strain 13 histocompatibility specificities are expressed on the cells of random-bred guinea pigs. The genetic locus controlling the expression of only one of those strain 13 histocompatibility specificities is linked to the GT immune response gene.

Stimulation Of

Rabbit anti-guinea pig lymphocyte serum is an efficient stimulus of the synthesis of DNA by guinea pig lymph node cells in vitro. The ability of ALS to stimulate lymphocytes is characterized by its lack of dependence on prior sensitization, the magnitude of the response it elicits, and the stimulation of all sensitive lymph node cells simultaneously within a very narrow range of ALS concentrations. In contrast to this homogeneous response to ALS, the stimulation of lymph node cells by antigen proceeds in graded fashion over a wide range of concentrations, thus reflecting the heterogeneity of the response of sensitized cells to antigen. PHA gives a response which is intermediate between that of ALS and antigen. ALS appears to have specificity for membrane determinants shared by lymphocytes but not found on other tissues. This specificity does not involve cell-bound gamma globulin. The serum activity mediating lymphocyte stimulation as well as cytotoxicity is readily removed by absorption with lymph node cells.

Supernates derived from incubated lymph node cells of Lewis rats sensitized to guinea pig spinal cord-Freund's adjuvant transfer experimental allergic encephalomyelitis (EAE) to syngeneic recipients. EAE supernatant transfer activity (EAE-STA) is not demonstrable in supernates derived from LNC of control donors not sensitized to nervous tissue. After addition of brain antigen to active supernates, EAE-STA is not longer demonstrable.

Passive transfer of experimental autoimmune myasthenia (EAM) was performed with lymph node cells from donor guinea pigs immunized with purified acetylcholine receptor (AChR) from Torpedo californica. Recipient animals revealed the same clinical signs and electromyographic patterns as observed in actively challenged animals. These phenomena are parallel to the clinical manifestations of the human disease myasthenia gravis, in which cellular response to AChR was recently demonstrated.

Abstract 1. The eosinophilic response of the guinea pig sensitized and reinjected with the specific antigen varies with the nature of the antigen used, but also with the individual guinea pig in any groupsensitized and reinjected with the same antigen. 2. Certain antihistamine drugs which abolish anaphylactic symptoms, do not abolish the eosinophilic response. 3. The severity of anaphylactic "shock" symptoms has no influence on the eosinophilic response. 4. Histamine phosphate has no effect on the eosinophil count of nonsensitized guinea pigs protected by benadryl; it causes a distinct eosinophilic response in sensitized animals. 5. Heparin—in the dose injected—produced only an insignificant rise in the peripheral eosinophil count of sensitized guinea pigs; adenosine had no effect. 6. Attempts were made to correlate the eosinophilic response in bone marrow, blood and shock tissue of guinea pigs sensitized and reinjected with a specific antigen. The variation within a wide range of the number of eosinophils in the bone marrow of nonsensitized and of sensitized, reinjected guinea pigs is emphasized. A definite correlation seems to exist between the presence of a large number of eosinophils in blood and lungs; it is shown, however, that this observation permits only limited conclusions. 7. The factors which account for discrepancies in the interpretation of the eosinophilic response, e.g., nature of antigen, route of administration and characteristics of species, are analyzed. 8. The significance of the findings is reviewed in the light of previous work.

Damage of rat embryo fibroblasts in the presence of sensitized lymph node cells reacting with specific antigen was shown to be closely correlated with delayed hypersensitivity in the animals from which the lymph node cells were taken. The phenomenon was not correlated with Arthus reactivity. In. animals sensitized with picryl conjugates of ovalbumin or human serum albumin, skin reactivity and the in vitro cytotoxic effect could be elicited only with the homologous conjugate or the protein carrier alone and not with picryl conjugates of heterologous proteins. Lewis rats developed more intense delayed sensitivity than BN rats, and Lewis lymph node cells were correspondingly more effective in producing specific damage of both syngeneic and allogeneic fibroblasts.

Shared idiotypy between B- and T-cell receptors specific for the antigen L-tyrosine-p-azophenyltrimethylammonium [tyr(TMA)] was studied in an antigen-binding assay using idiotypic antisera. These idiotypic reagents were prepared by inoculation of rabbits with purified anti-tyr(TMA) antibody raised in strain 13 guinea pigs. The antisera blocked 78-83% of the antigen-binding T cells (T-ABC) and 50-55% of the antigen-binding B cells (B-ABC) from tyr(TMA)-immune strain 13 and outbred lymph node cells (LNC). An excess of normal guinea pig Ig in the ABC assay did not affect the ability of the idiotypic antisera to block T- and B-ABC. Nylon wool-passed tyr(TMA)-immune LNC were trypsin treated resulting in a 75% loss of T-ABC. The trypsin-treated population was then cultured for 16 h which resulted in a return of T-ABC to 92% of pretrypsin values. 77% of these regenerated T-ABC could be blocked with idiotypic antisera. Specificity of the idiotypic antisera was tested in L-tyrosine-p-azobenzenearsonate-immune guinea pig LNC. Neither T- nor B-ABC were blocked in this heterologous system. Further blocking experiments were performed to characterize the nature of the T-ABC receptor. A variety of anti-Ig reagents, some of which block B-ABC, do not inhibit T-ABC suggesting that variable regions on T cells are not linked to Ig Constant regions.
