Immunologic Reconstitution

A 4-year-old girl who had received a fetal thymus gland by intraperitoneal transplantation 41 months previously sustained acute, fatal bronchiolitis due to culture-proven cytomegalovirus despite the fact that a specific antibody response to this organism was detected. While the thymic transplantation had increased the number of circulating T lymphocytes and had permitted immune sensitization to delayed-hypersensitivity skin test antigens, there was still an incomplete state of T lymphocyte function. In particular, isolated lymphocytes failed to respond to stimulation with phytohemagglutinin at several concentrations and, more important, the pathologic examination demonstrated a severe anatomic deficiency of lymphoid tissue associated with T lymphocyte function. The unusual infection that caused the death of this child emphasized the necessity of acquiring sufficient T lymphocyte function in immunologic reconstitution attempts.

Increased lycopene intake might have cardiovascular benefits, potentially through anti-inflammatory mechanisms. We recently showed that lycopene can influence lymphocyte activity by modulating processes involved in early cellular activation. T lymphocytes comprise different subsets, T cytotoxic, T helper 1 (Th1), T helper 2 (Th2) and T regulatory cells (Treg). We aimed to determine whether lycopene could specifically modulate T-cell subsets function and activity. Peripheral blood mononuclear cells from 11 healthy adults were cultured for 18hr to 60h in the presence of lycopene-enriched liposomes (0-1.18μg lycopene/ml) with or without mitogens. The secretion of cytokines representative of Th1,Th2 and Treg activities were measured by ELISA (IL-2, IL-1β, IL-10, IFN-γ and TGF-β) or cytometric bead array (IL-4, IL-10, IL17 and IFN-γ). The population profile of Tc (CD3+/CD8+), Th (CD3+/CD4+), Treg (CD4+/CD25+), and the Treg subsets nTreg (CD4+/CD25+/FoxP3+) and iTreg (CD4+/CD25+/IL-10+) was determined by flow cytometry. After 18h incubation, IL-2 concentration in the medium was significantly reduced (-29%, p=0.001) in the presence of lycopene (1.18μg/mL). Similar effects were observed after 36h and 60h culture for IFN-γ (-23%, p=0.015), Il-10 (-30%, p=0.023), IL-17 (-30%, p=0.019) but not IL-4 or TGF-β. The proportion of Treg cell was also significantly increased by 36% (p=0.001) in the presence of lycopene (1.18μg/mL) compared with non-treated activated cells. Furthermore, the proportions of iTreg cells were significantly increased by after incubation with lycopene while the proportion of nTreg cells decreased (-20.5 %, p=0.049). We conclude that increased lycopene intake may be beneficial against atherogenesis by modulating T lymphocyte function, particularly in relation toTh1 and Treg.

Abstract. To explore suppressor T lymphocyte function in Graves' disease, studies were performed in one group of patients in the hyperthyroid state and in another group in the euthyroid state after treatment. Peripheral blood lymphocytes were cultured for 1–7 days., Pokeweed mitogen (PWM; 1.25 μg/ml) was added at the initiation of the cultures or after 24 h. The degree of lymphocyte activation was assessed by measurements of the cellular uptake of [3H]thymidine and expressed in counts per minute (cpm). The suppressor lymphocyte function was estimated by a quotient between the maximum cpm values from cultures with and without pre-incubation. For the hyperthyroid group (n = 15) the quotient was 1.00 ± 0.07 (mean ± sem), for the euthyroid patient group (n = 21) 1.12 ± 0.05 and for the healthy control group (n = 21) 1.37 ± 0.08. There was a significant difference between the quotients for the control group and the hyperthyroid (P < 0.01) as well as the euthyroid (P < 0.05) patient group. The quotients for the two groups of patients did not differ significantly. In conclusion, the present study supports the view of a defect in suppressor T lymphocyte function in patients with Graves' disease in the hyperthyroid state and indicates that this defect can persist in the euthyroid state after treatment.
