Abstract
We previously indicated that intensity of the graft-versus-leukemia (GVL) effect varied among different leukemias in MHC-compatible, allogeneic bone marrow transplantation (BMT). Cellular factors responsible for differences in intensity of the GVL effect were examined by using two types of leukemias, i.e., a resistant leukemia (LE750) and a sensitive leukemia (8313) to induction of the GVL effect in MHC-compatible, allogeneic BMT of leukemia-bearing host. Resistance of LE750 leukemic cells to induction of the GVL effect could not be attributed to either less sensitivity to lysis by minor H antigen-specific, cytotoxic T cells or to an immunosuppressive activity of LE750 leukemic cells in leukemia-bearing host, when compared with the case of the sensitive leukemia (8313). To investigate the significance of the dose effect of effector cells for induction of the GVL effect, we used CD8+ T cells of AKR donor mice, which were shown to preferentially induce the GVL effect with hardly any lethal graft-versus host disease against C3H recipient mice, enabling us to increase the number of CD8+ T cells used in the allogeneic donor inoculum. The results suggested that the outcome of the antileukemic response in allogeneic BMT of leukemic recipients may be determined, at least in part, by the balance between the size of leukemic cells surviving and repopulating in the recipients after BMT and the number of antileukemic effector cells. The results furthermore indicated that when donors with T-cell subsets that preferentially induce an antileukemic response with reduced graft-versus-host disease are available, a more effective antileukemic response is inducible even against advanced leukemias.

Abstract
Ia restriction specificity involved in T cell proliferative responses to keyhole limpet hemocyanin (KLH) has been analyzed using a variety of allogeneic bone marrow chimeras. The chimeric mice were prepared by reconstituting irradiated AKR, SJL, B10.BR and B10.A(4R) mice with bone marrow cells from B10 mice. When such chimeric mice had first been primed with KLH in complete Freund's adjuvant (CFA), T cells from H-2 incompatible fully allogeneic chimeras showed significantly higher responses to KLH in the presence of antigen-presenting cells (APC) of donor strain (B10) than APC of recipient strain. However, in H-2 subregion compatible chimeras, [B10----B10.A(4R)], which were matched at the H-2D locus and at minor histocompatible loci, the T cells could mount vigorous responses to KLH with antigen-presenting cells (APC) of either donor or recipient type. The same results were obtained as well with chimeras that had been thymectomized after full reconstitution of lymphoid tissues by donor-derived cells. A considerable proportion of KLH-specific T cell hybridomas established from [B10----B10.A(4R)] chimeras exhibited both I-Ab and I-Ak restriction specificities. The present findings indicate that the bias to donor Ia type of antigen specific T cells is determined by donor-derived APC present in the extrathymic environment but that cross-reactivity to the recipient Ia is influenced to some degree by histocompatibility between donor and recipient mice, even though the histocompatible H-2D locus and minor histocompatibility loci seem not to be directly involved in the I-A restricted responses studied herein.

Abstract
It was tested whether the cytotoxic T-lymphocyte precursor (CLP) repertoire in normal mice is biased toward recognizing foreign antigen in association with self H-2 as opposed to allogeneic H-2. The frequencies of CLPs in normal mice (H-2b,k,d) specific for TNP-modified syngeneic and TNP-modified allogeneic cells have been compared by limiting dilution analysis. Normal spleen cells were cultured at a limiting dilution with TNP-modified (TNP-self) or TNP-modified allogeneic (TNP-allo) stimulator cells. Cultures were split into four aliquots and assayed against TNP-self, TNP-allo, unmodified syngeneic, and unmodified allogeneic Concanavalin A blast targets and classified for cytotoxic activity directed against TNP-self, TNP-allo, and allo H-2 determinants. In disagreement with our expectations from the literature, the frequencies of CLPs in H-2b and H-2d responder cells recognizing TNP-modified H-2k were higher than the frequencies of CLPs recognizing TNP-self. There was no clear preference for TNP-self in the case of H-2b responder and H-2d allogeneic cells, nor vice versa. Only in the case of H-2k responder cells was there a distinct preference for TNP-self. The significance of a considerable number of TNP-specific, allo H-2-restricted CLPs in normal lymphocytes is discussed.

Abstract
The regeneration and persistence of host- and donor-derived T cells were examined in the thymus as well as the spleen of mouse radiation bone marrow chimeras of two semiallogeneic combinations (F1----P, P----F1) with different Thy-1 markers on T cells of donor and host origins. An unexpectedly large number of host-type T cells were recovered from the spleens of F1----P chimeras, amounting to as high as 45 and 25% of total T cells at 6 and 14 weeks after bone marrow transplantation (BMT), respectively. To the contrary, the residual host-type T cells in the spleens of P----F1 chimeras disappeared quickly, resulting in less than 0.1% of total T cells at 6 weeks after BMT. It was also revealed that the number of host-type T cells in the spleens of F1----P chimeras decreased in proportion to increase of radiation dose given to the recipients.

Abstract
Bone marrow chimeras were produced between various combinations of young and old mice using either C57BL/6 mice only or a combination of C57BL/6 and B10.Thy-1.1 mice. The wet weight of the thymus and the number of thymocytes and splenic T cells of donor origin were assessed at appropriate intervals after the bone marrow transplantation. It was revealed that the old bone marrow was inferior to young in terms of the capacity to repopulate the thymus and splenic T cells. Moreover, some age-related qualitative changes appeared to occur in the thymocyte progenitors, as the composition of Lyt phenotype of donor-type T cells in the spleen was different between chimeras produced with young bone marrow and those with old.

Abstract
Fully H-2-incompatible chimeric mice were constructed by grafting lethally (950 rad) irradiated germ-free (GF) CBA (H2k) mice with anti-Thy 1 antibody plus complement-treated allogeneic C57Bl/6 (B6) (H2b) bone marrow cells. These chimeric mice were kept for more than 11 months, either under GF conditions or under barrier-sustained specific-pathogen-free (SPF) conditions. Controls included nonirradiated, nontransplanted, sex- and age-matched CBA and B6 mice raised under SPF conditions, and syngeneic chimeric mice of the CBA----CBA type kept under GF and SPF conditions. All chimeric mice were completely repopulated with donor-type lymphoid cells and showed no clinical or histological evidence of graft-versus-host disease. From the fully allogeneic chimeric mice, we enumerated the numbers of splenic cytotoxic T lymphocyte precursors (CTL-p) that could be clonally expanded under limiting dilution conditions in response to third-party alloantigens, or nonmodified and trinitrophenyl (TNP)-modified stimulator cells bearing host or donor H-2 antigens. The existence of high numbers of alloreactive and host- or donor-type H-2-restricted TNP-specific CTL-p in the spleens of fully allogeneic chimeras indicated almost normal immunocompetence. The surprising finding, however, was that large numbers of host (CBA)-reactive splenic CTL-p were inducible under limiting dilution conditions in healthy long-lived allogeneic chimeras, although these chimeric mice were devoid of any histological or clinical signs of graft-versus-host disease.

Abstract
Cytotoxic T lymphocyte (CTL) responses of splenic T cells from C57BL/6 B6) mice and mutant H-2Kbm1 (bm1) mice to haptenic (trinitrophenyl [TNP] ) and herpes simplex virus (HSV) determinants in the context of an allogenic (wild-type or mutant) H-2Kb molecule were analyzed in a modified limiting dilution system. In the B6-anti-bm1TNP mixed leukocyte reaction (MLR), estimated frequencies for precursors of CTL clones that lysed bm1TNP targets ranged from 1/120 to 1/400; in the bm1-anti-B6TNP MLR, estimated frequencies of precursors of CTL clones that lysed B6TNP targets ranged from 1/500 to 1/1,300. Estimated frequencies for precursors of CTL clones that lysed the respective unmodified and TNP-modified allogeneic targets were two- to three-fold lower. Lytic specificity patterns determined by split-well analysis showed that at least 20-30% of the generated CTL populations (selected for a high probability of clonality) in both MLR displayed allorestricted lysis of TNP-modified concanavalin A blast targets. In the B6-anti-bm1HSV MLR, estimated frequencies for precursors of CTL clones that lysed bm1HSV targets ranged from 1/70 to 1/300; in the bm1-anti-B6HSV MLR, estimated frequencies for precursors of CTL clones that lysed B6HSV targets ranged from 1/300 to 1/1,200. Again, estimated frequencies for precursors of CTL clones that lysed the respective noninfected and virus-infected allogeneic targets were two- to fourfold lower. Of the CTL populations selected for a high probability of clonality at least 30-60% displayed allorestricted lysis of virus-infected lipopolysaccharide blast targets in both MLR. It is concluded that a large fraction of clonally developing CTL populations stimulated with TNP-modified or HSV-infected allo-H-2Kb-bearing cells displayed an allorestricted pattern of recognition. It was further evident that the estimated frequencies of splenic precursors that generated allorestricted CTL clones was two- to threefold higher than the estimated frequencies of precursors that gave rise to the respective alloreactive CTL populations.

Abstract
Nylon wool-nonadherent spleen cells from three inbred mouse strains of H-2k (CBA), H-2d (BALB/c) and H-2b (C57BL/6) haplotype were co-cultured with 2,4,6-trinitrophenyl (TNP)-modified or nonmodified allogeneic stimulator cells in a limiting dilution system. Using a recently described restimulation protocol, a surprisingly large number of splenic cytotoxic lymphocyte precursors (CLP) was clonally expanded in this primary in vitro response to allo-H-2 plus TNP determinants; measured CLP frequencies ranged from 1/30 to 1/300. The lytic specificity patterns of individual microcultures (selected for a high probability of clonality) were defined by split well analysis, and were furthermore followed up in time by sequentially reassaying microcultures at different time points of in vitro incubation. This analysis revealed the following: a large fraction of cytotoxic T lymphocyte clones lysed TNP-modified but not nonmodified allogeneic concanavalin A blast targets, i.e., were allorestricted; this was found in all 6 allogeneic strain combinations set up with b, k and d haplotype mice; allorestricted lytic patterns predominated in microcultures with low numbers of responder cells per well, and at late time points of in vitro culture; allorestricted lytic cultures were specific for the stimulating allogeneic H-2 plus TNP determinant(s); and allorestricted lytic patterns were also found in microcultures stimulated by nonmodified allogeneic cells. To our knowledge, these are the highest CLP frequencies yet reported in limiting dilution systems that used a specific (re)stimulation protocol and measured the lytic responses obtained in a specificity-controlled readout.

Abstract
Using irradiation bone marrow chimeras to analyze restriction specificity of helper T cells, we found that recipient H-2 type dictated the H-2 type which the T cells recognize as self (adaptive differentiation). T cells from (H-2b----H-2k) chimeras cooperate with non-T cells bearing Iak to generate a vigorous PFC response to sheep erythrocytes (SRBC) in vitro, but not with genetically identical H-2b cells. However, when T cells from the chimeras and H-2b non-T cells were adoptively transferred into irradiated (donor X recipient) F1 mice with SRBC, marked responses were seen in recipient spleens where radio-resistant F1 macrophages might exist and act as antigen presenting cells (APC). From these in vitro and in vivo observations, we considered that in the primary antibody response to a T dependent antigen such as SRBC, only T cell-macrophage (APC) matching is required. In contrast, when T cells from H-2 incompatible chimeras which had been primed with SRBC in vivo were analyzed in vitro, these cells cooperated also with H-2b non-T cells. These findings indicate that there may be two separate stages of T cell differentiation during which the self restriction specificity is acquired: one appears to be responsive to intrathymic influences and is not associated with antigenic stimuli, and the other shows signs of being responsive to post-thymic stimuli and of involving antigenic presentation. Moreover, the latter appears to utilize the influence of donor type macrophages.
