Abstract
Type III pneumococcal polysaccharide (S3) coupled to spleen cells (S3-SC) has been shown to activate S3-specific Ts and Tcs in mice. Ts activation required I-J identity between carrier SC and Ts donors whereas I-A identity was required for Tcs activation. The carrier SC therefore presumably function as APC for Ts and Tcs activation by S3 since they are apparently not represented by APC present in the Ts and Tcs donors. The properties of the APC required for activation of S3-specific Ts and Tcs were determined by coupling S3 to various spleen cell subpopulations and assessing the ability of the various S3-SC populations to activate Ts and Tcs. The results indicate that Ts and Tcs are preferentially activated when S3 is presented on distinct cell types. S3-specific Ts were activated when S3 was coupled to plastic adherent cells. These cells are nonadherent to anti-Ig and nonfunctional in cyclophosphamide (Cy)-treated mice and their function is eliminated following treatment of cells with either anti-I-A or anti-I-J and C. In contrast, S3-specific Tcs were activated when S3 was coupled to anti-Ig adherent SC which bear I-A and the B cell marker J11d. These cells are functional in Cy-treated mice and their function is resistant to treatment with anti-I-J and C. Thus presentation of S3 on distinct cell types results in the preferential activation of T cells having opposing immunoregulatory function.

Abstract
C3H/He mice were found to be low responders in the contact sensitivity response to ABA. Intravenous injection of ABA-coupled syngeneic spleen cells induced hapten-specific Ts in C3H/He mice. These cells were Ts1 because they acted on the inductive phase of the contact sensitivity. They could suppress the contact sensitivity in H-2-compatible CBA mice which were known to be high responders to ABA. Using in vivo and in vitro systems for the induction of Ts, it was shown that I-A-I-J+Thy-1- adherent cells were necessary as APC for the induction of Ts1.

Abstract
Poly(Glu50Tyr50) (GT) is not immunogenic in most inbred mouse strains. GT injection produces an I-J--bearing, GT-specific T-cell--derived suppressor factor (GT-TsF1) in H-2b,d,k haplotype mice. GT-TsF1 generates second-order suppressor T cells (Ts2) in H-2a,d,k haplotype mice. Here, we show that in order for GT-TsF1 to act, the recipient strain must express I-E molecules. This suggests that T cells are not the primary target of GT-TsF1. GT-TsF1 can be presented by Ia+ A20-2J B lymphoma cells. GT-TsF1 presentation is blocked by anti-I-E, but not by anti--I-A, mAb, whereas GAT presentation is blocked by anti-I-A, but not by anti--I-E, mAbs. These data suggest that I-J recognizes (or is recognized by) I-E. The existence and role of I-J molecules in immune regulation are discussed in light of these data.

Abstract
I-J originally mapped within the murine major histocompatibility complex (H-2) between the EB and Ea loci using intra-H-2 recombinants. Cloning of this segment of H-2 shows no DNA that can be ascribed to I-J. Various hypotheses have attempted to explain this dilemma. One hypothesis attributes a chromosome 4 locus with I-Jk expression. This hypothesis requires the AKR/J and A/WySn mouse strains to be I-Jk negative. In the present report we show that AKR/J spleen cells express I-Jk surface molecules and that both the AKR/J and A/WySn mouse strains produce functional I-Jk-bearing suppressor factors to poly(Glu50Tyr50). Our data imply that mapping of I-J-determining genes to chromosome 4 may be premature.

Abstract
This review attempts to sort out the differences between macrophage and T cell I-J determinants. We propose that suppressor T cells have receptors for self-I-J determinants which are expressed on macrophage-like accessory cells. The I-J determinants associated with accessory cells are responsible for the selection of the Ts receptors. Although the major histocompatibility complex is involved in the selection of Ts receptors, the receptors themselves need not be encoded by genes which reside within the MHC. In fact, the molecular genetic evidence presently available has established that suppressor T cell factors do not express gene products associated with the postulated I-J region of the H-2 complex. In spite of the failures of biochemists and molecular geneticists to identify I-J genes and gene products, there is extensive biological data demonstrating the existence of I-J. The activity of anti-I-J reagents has been verified by numerous laboratories. Sera containing anti-I-J activity have been prepared in many strain combinations. Immunization between a variety of strains differing at the purported I-J region produce active anti-I-J antibodies (Murphy et al. 1976, Tada et al. 1976, Pierres et al. 1977, Tada et al. 1978). Furthermore, in many suppressor cell systems the interactions of Ts cells and factors are restricted by I-J (Tada & Okumara 1980, Sorensen & Pierce 1982, Green et al. 1983, Dorf & Benacerraf 1984). Most investigators who have attempted to detect I-J have analyzed T cells. Since we propose that T cells express a complementary anti-I-J receptor, subsequent efforts at identifying I-J should include analysis of macrophage I-J determinants. In spite of extensive biological data, we still do not know if I-J is a protein, carbohydrate or lipid. In addition, the role of H-2 in determining I-J structure is unknown. Nevertheless, the overwhelming biological data demonstrate that I-J is an important structure for suppressor T cell interactions. Much remains to be accomplished, including the characterization of I-J products and locating the I-J genes.

Abstract
The phenomenon of associative recognition, i.e., the recognition of antigen together with major histocompatibility complex products (MHC) was studied in a model system. T-acceptor cells armed with antigen-specific T-suppressor factor (TsF) released a nonspecific inhibitor of the transfer of contact sensitivity when exposed to antigen together with MHC. The MHC product occurred in a KCl extract of cells and behaved genetically and serologically as I-J. Cells armed with anti-picryl or anti-"oxazolone" TsF could be triggered by the corresponding "bis-picryl-L-lysine" and "bis-oxazolone-L-lysine" together with MHC. This suggested that cross-linking of antigen recognition sites on separate molecules of TsF might be required. To investigate this possibility the bifunctional "mixed" hapten "N alpha-picryl-N epsilon-oxazolone-L-lysine," which is univalent with respect to the picryl and oxazolone haptenic groups, was synthesized. This triggered cells armed with a mixture of anti-picryl and anti-oxazolone TsF but not cells armed with either TsF alone. It was concluded that both occupancy of the I-J recognition site and the cross-linking of separate molecules of TsF was required for triggering. Moreover the hapten and the KCl extract could be given sequentially and in either order. This finding suggested that the triggering of the release of nonspecific inhibitor was due to the separate recognition of I-J and antigen and not to new antigenic determinants produced by their interaction.

Abstract
The mechanism by which I-J restrictions were imposed on second-order suppressor cells (Ts2) was analyzed. The induction of Ts2 cells requires presentation of an inducer suppressor factor by a specialized population of factor-presenting cells. The I-J phenotype of this factor-presenting population controls the H-2 restriction of the Ts2 cells. The splenic cells responsible for presenting inducer factor appear to be of macrophage or dendritic cell lineage. Several homologies exist between the mechanism responsible for the induction of H-2-restricted suppressor and helper T cells. Thus, the I region products on specialized presenting cells determine the specificity and genetic restrictions of the T cell. In an H-2 heterozygous F1 animal, two distinct populations of cells can be induced, one specific for each parental H-2 heplotype. Furthermore, the data suggest that the suppressor cells also bear receptors for self H-2 products. The ramifications of these observations for the suppressor cell cascade are discussed.

Abstract
The proliferative response of spleen cells, obtained from Syrian hamsters sensitized to hen egg albumin emulsified in complete Freund's adjuvant, is lower in magnitude than the response of draining lymph node cells. In this study, the cellular regulatory mechanisms which may lead to splenic hyporesponsiveness were examined. Although unfractionated spleen cells were not suppressive, the addition of nylon wool nonadherent normal spleen cells to sensitized draining lymph node (target) cells markedly suppressed antigen- but not mitogen-induced proliferation. Suppressor cell activity was not detected in normal lymph nodes. Suppression could be overcome by culturing splenic suppressor plus target cell mixtures in the presence of large quantities of antigen. Suppressor cell activity was radioresistant. In addition to nonadherent suppressor cells, the hamster spleen also contains an adherent cell population(s) which amplified antigen-induced proliferation. Adherent cells with amplifying activity were also present in lymph nodes. The addition of adherent cells abrogated splenic suppression of proliferation. Collectively, these data indicate that the hamster spleen contains both suppressive and amplifying leukocyte subpopulations which may be involved in the regulation of the immune response to certain antigenic stimuli.

Abstract
Antigen-specific suppressor T-cells in delayed-type hypersensitivity (DTH) to BCG were induced in vitro. Normal spleen cells of C3H/He mice were incubated with 50 micrograms of PPD per ml for 4 days at 37 degrees C, and the non-adherent cells in the culture were transferred intravenously into cyclophosphamide (CY)-treated syngeneic recipients. The recipients were immunized to BCG immediately after the cell transfer, and DTH was measured by the footpad reaction to PPD two weeks later. Footpad reaction to PPD was positive in CY-treated C3H/He mice immunized to BCG, while it was suppressed by the transfer of the in vitro induced suppressor cells. When the suppressor cells were treated with anti-thy-1.2 antiserum and complement before transfer, the suppression was abrogated. Next, the spleen cells were separated into plastic adherent and non-adherent fractions. After treatment with anti-thy-1.2 and complement, the adherent cells were treated with either anti-I-Jk or anti-I-Ak antiserum and complement. Then, they were reconstituted with the non-adherent cells and cultured with PPD. Treatment of the adherent cells with anti-I-Jk antiserum and complement abrogated the suppressor cell induction, while the treatment with anti-I-Ak had no effect. These facts indicate that I-J positive non-T-adherent cells play an essential role in the induction of suppressor cells in DTH.

Abstract
Antigen-specific suppression to poly(Glu50-Tyr50) (GT) is under the control of two complementary immune suppressor (Is) genes located in the major histocompatibility (H-2) complex of the mouse. Suppressor strains of mice produce both suppressor T (Ts) cells and Ts-derived suppressor factors (TsF) that bear antigenic determinants of the I-J subregion of the H-2 complex. Nonsuppressor strains of mice, on the other hand, are not suppressed by GT preimmunization. These nonsuppressor mice, however, can be classified according to those that lack the ability to make GT-specific T cell-derived suppressor factor (GT-TsF) after GT injection (i.e., H-2a, I-Jk mice) and those that lack the ability to be suppressed by the appropriate GT-TsF (i.e., H-2b,g2, I-Jb mice). In the present study, we demonstrate that (H-2a x H-2b,g2)F1 hybrid mice produce distinct GT-specific suppressor factors of both parental I-J haplotypes. Moreover, only the I-Jb-bearing GT-TsF derived from these F1 hybrid mice is able to induce second-order suppressor cells (Ts2). This is consistent with the observation that injection of GT-TsF1 derived from C57BL/6 (I-Jb) mice into A/J (I-Jk) mice leads to the production of an antigen-specific I-Jk GT-TsF2. Our results suggest that Is gene complementation occurs through a different cellular mechanism that was previously observed for Ir gene complementation. Further, we show that complementing (non-suppressor X nonsuppressor)F1 hybrid mice produce an I-Jb (and not an I-Jk) GT-TsF1 and an I-Jk (not an I-Jb) GT-TsF2, thus suggesting a heterogeneity of Ia loci within the I-J subregion. Data presented in the present study suggest that there may be even more heterogeneity within the I-J subregion than has has been heretofore reported with regard to I-J expression on Ts.

Abstract
A monoclonal anti-I-Jb serum designated D-7 reacts in high titer with three different T-cell subsets and one cell-free product involved in generating contrasuppressive activity, but has no activity against I-J T-cell subsets (or their cell-free mediators) involved in feedback suppression. These results give evidence for heterogeneity in the I-J subregion. They also indicate that the serological markers on I-J+ cells may define the functional activity of the regulatory circuits they belong to. Clearly, they do not separate the role that the cells play within a particular immunoregulatory circuit, i.e., inducer, transducer, or effector cells.

Abstract
Immune Ly-1-,2+ splenic T cells release material(s) (Ly-2 TsF) into culture supernatants which (a) are antigen-specific and (b) do not contain gene products of the I-region of the MHC (major histocompatibility complex) (within the limits or our detection system) and which can lead to antigen-specific suppression of spleen cell cultures depleted of all Ly-2+ (Ly-2 and Ly-1,2) cells. The cells which make Ly-2 TsF possess no detectable I region- or Qa-1-encoded determinants. Nonetheless, the ability of the material(s) to suppress target cells is restricted by genes closely linked to the MHC. No demonstrable evidence for a role of the polymorphic portion of genes linked to the Ig locus for this suppressive interaction to occur could be found. It is suggested that this material(s) may be the final effector moiety of the suppressor circuit because (a) it does not require the presence of any Ly-2+ cells to work, and (b) in contrast to material(s) which induce suppression, there is no latent period; i.e. the Ly-2 TsF suppresses both the early and late phases of the immune response in primary Mishell-Dutton cultures. The MHC restriction that is imparted to the biologically active material is likely to be due to its "anti-MHC" activity. Since this is the first report in which the presence of I-J-controlled gene products was investigated on an antigen-specific, Ly-2 cell-produced suppressor factor that worked in the absence of Ly-2+ cells in the assay culture, the possibility that many, if not all, antigen-specific suppressor effector cells and molecules are "I-J-" must be considered.

Abstract
A non-T:non-B accessory cell in peritoneal washout or spleen-cell suspensions facilitates T-cell proliferative responses to the mitogen, concanavalin A. Utilizing monoclonal antibody, we show that this accessory cell bears the same I-A- and I-E-subregion controlled determinants as found on B cells. In addition, the same accessory cell bears a Tla(Qa-1?)-region and an I-J-subregion controlled determinant. This I-J determinant is also present on splenic accessory cells involved in in vitro antibody responses to sheep red blood cells. Data in a companion paper show that not all anti-I-J sera contain antibody reactive with the accessory cell, and suggest that T cells involved in the generation of suppressor activity and accessory cells bear different I-J-subregion controlled determinants.
