*  THE MIXED LEUCOCYTE REACTION APPLIED TO INBRED MOUSE STRAINS,
The mixed leucocyte reaction, (MLR), has been applied successfully to peripheral blood leucocytes of the mouse. Before harvest, the leucocytes were mobilized into the peripheral blood by a single intravenous injection of the mice with pertussis vaccine. Mixtures, (50-50), of C57BL/6 and DBA/2 mouse leucocytes were cultured in medium containing low amounts of mouse plasma and supplemented with foetal bovine serum. DNA-synthetic activities at selected times were determined by liquid scintillation counting following pulse labeling of the cell populations with 3H-TdR. DNA synthesis in the mixed cultures attained a maximum value at the 5th to 7th day (7,500 cpm), as contrasted with maximum control values of 200-1000 cpm). Considerable DNA synthesis (1000-2000 cpm), also was observed at zero time, and then declined to low levels (200-300 cpm) at the 18th hour. DNA synthesis did not occur in the mixed leucocyte ...

*  Stable Down-Regulation of HLA Class-I by Serum Starvation in Human PBMCs
Background: The human leukocyte antigen (HLA) matching between organ donor and recipient is an acceptable strategy in clinical transplantation since 1964. However, in bone marrow transplantation, finding matched donors is often problematic. Thus new method for down regulation of HLA can be an alternative strategy to solve this problem. Objective: To examine the effect of serum starvation on HLA class I expression in human peripheral blood mononuclear cells (PBMCs). Methods: PBMCs were cultured in RPMI-1640 supplemented with 10% FBS (non-starved cells) as well as in medium only (starved cells) for 16, 24, 48, 72, 96h under standard cell culture conditions. The pattern of cell death and HLA class I expression was determined by flowcytometry. Antigenicity of the starved PBMCs was evaluated in a one-way mixed lymphocyte culture by MTT assay. Results: Mean fluorescence intensity (MFI) of different indicated starved PBMCs ...

*  Resting and sensitized T lymphocytes exhibit distinct stimulatory (antigen-presenting cell) requirements for growth and...
Previous studies have shown that unprimed or resting T lymphocytes will grow and release lymphokines when stimulated by dendritic cells (DC). We now have examined the stimulatory requirements for antigen-primed or blast-transformed T cells. The latter were derived from dendritic/T cell clusters that developed during the primary mixed leukocyte reaction (MLR). The specificity of the blasts was established by a binding assay in which most T cells aggregated small B lymphocytes of the appropriate haplotype within 2 h at 4 or 37 degrees C. Since unprimed T cells did not aggregate allogeneic B cells, we suggest that DC induce T lymphocytes to express additional functioning receptors for antigen. Lyt-2-T blasts did not grow or release interleukin 2 or B cell helper factors unless rechallenged with specific alloantigen, whereupon growth (generation time of 14-18 h) and lymphokine release rapidly resumed. The blasts could be stimulated by allogeneic ...

*  Role of the pineal gland in immunity. Circadian synthesis and release of melatonin modulates the antibody response and...
Inhibition of synthesis of the pineal neurohormone melatonin (MEL) in mice, by administration of propranolol (PRO) in the evening, and daily injections of p-chlorophenylalanine (PCPA), resulted in a significant depression of the primary antibody response to sheep red blood cells (SRBC). Spleen cells from these mice showed a reduced reactivity against antigens in the autologous mixed lymphocyte reaction (AMLR). In contrast, alloreactivity remained normal. Reconstitution of the night-time peak of plasma MEL by evening injections to the mice completely reversed the suppression of the humoral response and the AMLR. MEL administration was able to antagonize the depression of antibody production induced by corticosterone in vivo. These results suggest that the pineal gland has important immunomodulatory functions through its cyclic, circadian release of MEL.

*  Human T-cell clones from autoimmune thyroid glands: specific recognition of autologous thyroid cells. - The Kennedy Institute...
The thyroid glands of patients with autoimmune diseases such as Graves' disease and certain forms of goiter contain infiltrating activated T lymphocytes and, unlike cells of normal glands, the epithelial follicular cells strongly express histocompatibility antigens of the HLA-DR type. In a study of such autoimmune disorders, the infiltrating T cells from the thyroid glands of two patients with Graves' disease were cloned in mitogen-free interleukin-2 (T-cell growth factor). The clones were expanded and their specificity was tested. Three types of clones were found. One group, of T4 phenotype, specifically recognized autologous thyroid cells. Another, also of T4 phenotype, recognized autologous thyroid or blood cells and thus responded positively in the autologous mixed lymphocyte reaction. Other clones derived from cells that were activated in vivo were of no known specificity. These clones provide a model ...

*  CONSEQUENT INTRAFAMILIAL IMMUNIZATION FOR DL-A HAPLOTYPING IN CANINES | JEM
A procedure of intrafamilial immunization is described for production of antisera recognizing DL-A haplotypes. In a colony consisting of 1 sire, 6 bitches, and 67 offspring all haplotypes could be accurately allocated. In the colony the observed reaction frequencies of the antisera are in agreement with mendelian codominant inheritance. Mixed lymphocyte culture tests confirmed the accuracy of the serologic typing and the presence of homozygous individuals within the colony. Further evidence is presented supporting the presence of two or more subloci within the DL-A system. Colonies of canines such as the one described should provide a sensitive system for evaluating interaction between serologic DL-A typing, MLC reactivity, and immune response genetics in a nonrodent species which is not highly inbred.. ...

*  Coupled complementation of immune response genes controlling responsiveness to the H-2.2 alloantigen. | JEM
The ability of various B10 congenic resistant strains to respond to the alloantigen H-2.2 was tested. High and low antibody-producing strains were distinguished by their anti-H-2.2 hemagglutinating respones. However, these strains do not differ in their ability to respond to these antigenic differences in the mixed lymphocyte culture. The humoral response to the H-2.2 alloantigen was shown to be controlled by two interacting genes localized within the H-2 complex. Thus, F1 hybrids prepared between parental low responder strains could yield high level immune responses. In addition, strains bearing recombinant H-2 haplotypes were used to map the two distinct genes controlling the immune response. The alleles at each locus were shown to be highly polymorphic as evidenced by the asymmetric complementation patterns observed. The restricted interactions of specific alleles was termed coupled complementation. The significance of ...

Five Chinese rhesus macaques which received decellularized porcine corneal lamellae and were followed up for at least 6 months underwent full-thickness corneal allotransplantation. Previous xeno-grafts (7.5mm in diameter) were removed with 8.0mm trephines and 8.5mm-sized grafts from donor macaques were transplanted. Clinically applicable minimal immunosuppression was done based on topical, subconjunctival and systemic corticosteroids. Rejection signs and serial changes in recipients blood profile, including memory T cell subset, anti-Gal and donor pig specific antibodies, and complement were evaluated. Changes in aqueous complement concentration were also assessed at 4 weeks after transplantation. The mixed lymphocytes reaction (MLR) was analyzed in three rhesus macaques (KPed rhesus) with clear allografts that survived more than 6 months. MLR was done using peripheral blood mononuclear cells (PBMC). PBMCs from the recipient rhesus and normal rhesus were used as responder ...

*  In Vivo Effects of Calcitriol on Phenotypic and Functional Properties of Dendritic Cells
Background: Dendritic cells (DCs) play a central role in the initiation and expansion of T cell mediated immune responses with potential immunotherapy application. The compounds which have the ability to induce immunomodulatory effects on DCs may be employed for the treatment of immunopathologic conditions such as autoimmune diseases. Objective: The aim of this study was to investigate the in vivo effects of calcitriol (active form of vitamin D3) on DCs. Methods: 0.1 microgram calcitriol was injected intra-peritoneally into C57BL/6 mice every other day within 3 weeks, and spleen DCs were extracted by magnetic beads. The phenotypic and functional properties of DCs were studied by flow cytometry and mixed lymphocyte reaction (MLR), respectively. Results: The expression of CD86 and MHC II, as maturation markers and costimulatory molecules were significantly decreased (p=0.028 and p=0.047, respectively) while CD11b expression, as a marker of mice myeloid DCs which mostly induces ...

*  Modulatory role of regulatory T cells in a murine model of severe equine asthma | BMC Veterinary Research | Full Text
In this paper, we describe that the transient decrease of CD4+, CD25+, Foxp3+ splenic T regulatory cells, induced by Cy, correlates with increased airway inflammation in mice exposed to hay contaminated with Aspergillus fumigatus.. The results presented here demonstrate that, in our experimental model, older animals (8 months old) showed a higher percentage of CD4+, CD25+, Foxp3+ cells in the spleen when compared to younger mice (2 months old). Similar findings were reported by Zhao [28], who also compared the capacity of CD4+, CD25+ cells from older and younger mice to inhibit delayed hypersensitivity, mixed lymphocyte reaction or cytokine production. From their results, they concluded that CD4+, CD25+ cells present in the older mice, were less effective in suppressing the above-mentioned assays. These facts may explain why aging produces a progressive decline in immune regulation, and in the case of horses and in the mice of our experimental model [20], why age facilitates ...
