Donor-specific blood transfusion prolongs survival of fully allogeneic ACI (RT1a) renal grafts in PVG (RT1a) recipients from 6-8 days to greater than 100 days. To determine how DSBT alters effector cytotoxic cell responses, we tested freshly isolated peripheral blood lymphocytes, spleen cells, and graft infiltrating cells (GIC) from pairs of PVG recipients of ACI kidneys pretreated with DSBT or autologous blood transfusion (ABT) for cell-mediated lympholysis, antibody-dependent cellular cytotoxicity (ADCC), and natural killer activity at the day of transplantation (day 0) and days 3 and 6 posttransplantation. PBL and GIC from the same pairs of animals were examined for their phenotypic profile (CD4, CD8, 3.2.3 NK cell marker, IL-2 receptor). CML, ADCC, and NK activity were higher in PBL than splenocytes of GIC of both ABT and DSBT groups at all time points examined. CML activity of PBL at day 3 was significantly higher in DSBT vs. ABT recipients (P less than 0.01), while at day 6 both groups were equally elevated. Splenocytes demonstrated significantly lower CML activity in DSBT vs. ABT recipients at day 6 (P less than 0.05). CML activity of GIC eluted from ABT and DSBT kidneys was not detected at day 3, but was significantly elevated and equivalent in both groups at day 6. ADCC and NK activities of PBL did not differ between ABT and DSBT groups, and were negligible in splenocytes. GIC demonstrated higher NK activity in DSBT vs. ABT recipients at day 3 (P less than 0.05), while ADCC activity was not detectable at any time in either group. Phenotypic analysis of PBL and GIC at day 3 showed no significant differences between ABT and DSBT groups in the percentage of CD4 or CD8 cells. However, in both ABT and DSBT groups the ratio of CD4:CD8 cells was markedly lower in GIC than PBL. By day 6, PBL from both ABT and DSBT groups showed equivalent and significant decreases in CD4+ cells and increases in CD8+ and 3.2.3+ (NK) cells. The percentage of IL-2R+ cells remained low (less than 5%) in both groups at day 3. In contrast, at day 6 there was a significant increase in IL-2R+ (and to a lesser extent CD4+) GIC in ABT- but not DSBT-treated recipients, while CD8+ cells were significantly increased in both groups.(ABSTRACT TRUNCATED AT 400 WORDS)

D007111 Immunity, Cellular Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity.

D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D007694 Killer Cells, Natural Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D003602 Cytotoxicity, Immunologic The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000920 Antibody-Dependent Cell Cytotoxicity The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent.
