Abstract
Current attempts to find a vaccine for tuberculosis (TB) are based on the assumption that it must drive a Th1 response. We review the evidence that progressive disease might not be due to absence of Th1, but rather to the subversive effect of an unusual Th2-like response, involving interleukin-4 (IL-4) and IL-4delta2. This Th2-like response can impair bactericidal function and lead to toxicity of tumour necrosis factor-alpha (TNF-alpha) and to pulmonary fibrosis. If this is important, effective vaccines will need to suppress pre-existing Th2-like activity. Such vaccines are feasible and are active therapeutically in mouse TB.

Abstract
Repeated administration or chronic presence of antigen during CD4(+) T cell activation and a cytokine milieu enriched in IL-4 favour the generation and maintenance of a T(h)2 population. However, there is little data on how these factors affect adult human CD8(+) T cell functions. We established in vitro conditions to culture purified human CD8(+) T cells, and investigated how repeated stimulation and exogenous IL-4 modulated their functions. Repeated TCR-CD3 stimulation of CD8(+) T cells increased the number of CD25-, CD30- and CD40 ligand-expressing cells, and their capacity to secrete IL-4 and IL-5. In addition, repeatedly stimulated CD8(+) T cells had cytotoxic activity and provided help to resting B cells for IgE synthesis. The presence of exogenous IL-4 during repeated stimulation further increased the number of CD25(+) and CD30(+) CD8(+) T cells, up-regulated the number of IL-5(+) cells, and increased IL-5 levels released. These observations demonstrate that repeated TCR-CD3 stimulation of normal human CD8(+) T cells favoured the growth of cells with a type 2 phenotype and that this was further amplified by the presence of IL-4. These mechanisms may be important in virus-induced lung eosinophilic inflammation in healthy subjects and virus-induced exacerbations of asthma.

Abstract
The aim of this study was to examine the cytokine production and cytokine responsiveness of the first T-cell receptor (TcR) positive cells that appear in the murine fetal thymus, namely TcR V gamma 3 cells. It is shown that IL-2-cultured fetal TcR V gamma 3 thymocytes were capable of producing IL-3, GM-CSF, TNF-alpha and IFN-gamma upon TcR triggering. IL-2, IL-4, IL-5 and IL-6 could not be detected. With regard to cytokine responsiveness, TcR V gamma 3 cells proliferated to a high extent when high concentrations of rIL-2 were added. rIL-4 or rIL-7 alone, but not rIL-1 alone, were capable of inducing a modest proliferation of TcR V gamma 3 thymocytes. When combined with low concentrations of IL-2, a synergistic effect could be observed with IL-1, IL-4 or IL-7. It is shown that the synergistic effect of IL-2 with IL-4 was mainly due to induction of IL-2 receptor expression. The synergistic effect of IL-2 and IL-7 on the proliferation of TcR V gamma 3 cells could only be partially inhibited by anti-IL-2 receptor MoAb, and this antibody had no effect on the IL-2 + IL-1 cultures. These observations can explain the extensive proliferation of TcR V gamma 3 thymocytes during fetal life and they indicate that TcR V gamma 3 thymocytes have the potential to play a functional role during fetal thymus development.

Abstract
We investigated the anti-tumor effects of recombinant mouse interleukin (IL)-4 and IL-5 by using a transplantable B cell lymphoma 38C13 cell line as a model. Daily local administration of either IL-4 or IL-5 produced moderate but significant inhibition of the rate of local tumor growth and prolongation of mean survival time (MST) in syngeneic C3H/HeJ mice; these anti-tumor effects appeared to plateau at low doses. Histopathologic and immuno-histochemical examination revealed necrotic changes in the cytokine-treated tumors, associated with infiltration of inflammatory cells such as eosinophils, macrophages, and lymphocytes. The infiltrating lymphocytes were found to be Thy-1.2+ T cells. To elucidate the importance of T cells, the rate of tumor growth and the MSTs were compared between athymic T cell-deficient BALB/c nude mice and immunocompetent C3H/HeJ mice. In the nude mice the transplanted tumor grew more rapidly and the MST was shorter than in the normal mice, suggesting a significant contribution of infiltrating T cells in the anti-tumor effects of the interleukins. Lastly, in vitro, growth inhibition of the 38C13 cells was observed in a dose-dependent manner at relatively high concentrations of either cytokine. Therefore, we conclude that both IL-4 and IL-5 have moderate anti-tumor effects against 38C13 B cell lymphoma both in vivo and in vitro, and that the observed in vivo anti-tumor effects are probably mediated both by tumoristatic action of infiltrating cells, such as eosinophils, macrophages and T lymphocytes, and by direct anti-proliferative action of the recombinant cytokines.

Abstract
The activity of distinct CD4+ T-helper cell (Th) clones in promoting secondary A/PR/8/34/Mt.S.(H1N1) (A/PR8) influenza virus-specific, class I-restricted cytotoxic T-lymphocyte (CTL) responses in vitro was examined. CD8+ T cells which had been purified by fluorescence-activated cell sorter from spleen cells of A/PR8-primed mice were used as responders. On their own, purified CD8+ T cells were unable to generate cytotoxic activity upon in vitro culture with A/PR8-infected stimulator cells. Significant cytotoxic activity was generated in cultures that were additionally supplemented with A/PR8-specific Th clones or cell-free supernatant from these clones. Although there were large differences among individual Th clones in this function, Th clones of type 1 (Th1) promoted, on average, significantly stronger cytotoxic responses than Th clones of type 2 (Th2). The differences in promotion of a cytotoxic response correlated with the amount of interleukin-2 (IL-2) or IL-4 secreted by individual Th clones. These two lymphokines accounted for the CTL-promoting activity of the respective Th clones, since addition of recombinant IL-2 (IL-2) or rIL-4 to Th-free cultures substituted fully for the respective Th clones. As observed with Th clones, rIL-2 was significantly more effective than rIL-4 in promoting a cytotoxic response. When used in combination, Th2 clones had an antagonistic effect on the generation of a CTL response by Th1 clones. This effect could be partially transferred with cell-free supernatant from activated Th2 clones and could be reversed by addition of excess rIL-2. Both consumption of IL-2 by Th2 and secretion of an inhibitory factor(s) appear to be involved in this phenomenon.

Abstract
T cell activation induced via cross-linking of the T cell receptor (TcR) stimulates hydrolysis of phosphatidylinositol to the second messengers diacylglycerol (DAG) and inositol 1,4,5-triphosphate (IP3). DAG is necessary for the activation and function of protein kinase C (PKC) which is suggested to play a key role in the cascade of signal transduction when translocated from the cytosol to the cell membrane. In this report, we investigated responses of resting vs. activated Ly-2+ and L3T4+ T lymphocytes in the presence of the PKC inhibitor H7 [1-(5-isoquinolinylsulfonyl)-2-methylpiperazine]. H7 inhibited the induction of primary T cell proliferation, while interleukin 2 (IL 2) production was fully retained. The effect of the PKC inhibitor on primary T cells depended on the type of ligand interacting with the TcR: increasing doses of concanavalin A or of immobilized anti-CD3 monoclonal antibody (mAb), but not of anti-V beta 8 or of anti-TcR alpha/beta mAb, partly overcame the blockade, indicating a differential signaling compared to the former stimuli. The blockade of T cell proliferation by H7 was not due to an inhibition of PKC translocation, but occurred even 4-8 h after T cell induction and correlated with a significant reduction of IL 2 receptor (IL 2R) expression. In contrast, the mRNA levels of IL 2R and the cellular proto-oncogenes c-fos and c-myc were not affected. On activated T cells, H7 neither blocked proliferation nor IL2R expression. Consequently, H7 dissects the signal resulting in T cell proliferation from those governing the triggering of other T cell functions, i.e. IL 2 production, during primary responses of Ly-2+ or L3T4+ murine T lymphocytes.

Abstract
We have analyzed the effect of human recombinant interleukin 4 (rIL-4) on the growth and differentiation of human intrathymic pre-T cells (CD7+2+1-3-4-8-). We describe that this population of T cell precursors proliferates in response to rIL-4 (in the absence of mitogens or other stimulatory signals) in a dose-dependent way. The IL-4-induced proliferation is independent of the IL-2 pathway, as it cannot be inhibited with an anti-IL-2 receptor alpha chain antibody. In our culture conditions, rIL-4 also promotes the differentiation of pre-T cells into phenotypically mature T cells. Although both CD3/T cell receptor (TCR)-alpha/beta + and CD3-gamma/delta + T cells were obtained, the preferential differentiation into TCR-gamma/delta + cells was a consistent finding. These results suggest that, in addition to IL-2, IL-4 plays a critical role in promoting growth and differentiation of intrathymic T cell precursors at early stages of T cell development.

Abstract
In this study we examined the effect of interleukin 4 (IL 4) on T cell activation and proliferation via the alternative CD2 pathway. To this end highly purified human resting T cells were cultured with a stimulating pair of anti-CD2 monoclonal antibodies in the absence of accessory signals from monocytes. Addition of either recombinant (r)IL 2 or rIL 4 resulted in proliferation of the anti-CD2-stimulated T cells. The growth-promoting effect of rIL 4 on preactivated. T cells was shown to be partly a direct effect. rIL 4 also induced IL 2 production and, as a consequence, the effect of rIL 4 on T cell growth was enhanced by endogenously produced IL 2. Moreover, rIL 4 acted in synergy with exogenously added rIL 2 in promoting growth of anti-CD2-stimulated T cells. The synergistic effect of IL 2 and IL 4 could be explained by IL 2-induced up-regulation of IL 4 responsiveness. In contrast, preincubation with rIL 4 did not enhance IL 2 responsiveness and rIL 2 but not rIL 4 up-regulated IL 2R expression on anti-CD2-stimulated T cells. Finally we could demonstrate that monocyte-produced cytokines (IL 1 and IL 6) enhance the proliferative response to rIL 4 of anti-CD2-stimulated T cells. It can be concluded that IL 4 can act as a paracrine growth factor for T cells activated in the alternative CD2 pathway, and that it acts synergistically with IL 2, IL 1 and IL 6. Moreover, IL 4 is a helper signal for IL 2 production. Thus, IL 2 and IL 4 are involved in a bidirectional regulatory network, with IL 4 as an inducer of IL 2 production, and IL 2 as an enhancer of IL 4 responsiveness.

Abstract
T cell stimulation occurs following interaction of T cell receptor (TcR) with processed antigen presented by autologous accessory cells (AC). The effects of antigen stimulation on T cells are mimicked by monoclonal antibodies (Mabs) defining proteins of the TcR-CD3 complex. In this study, we examine the roles of T cell density, AC density, divalent and polyvalent forms of anti-CD3 Mab, and the cytokines interleukin (IL)-1, IL-2, and IL-6 in T cell activation and proliferation. Stringently AC-depleted T cells do not proliferate in response to Con A or divalent anti-CD3; however, polyvalent anti-CD3 provides a powerful signal for isolated resting T cell proliferation. Recombinant (r)IL-2 strongly amplifies T cell proliferation in response to anti-CD3, whereas rIL-1 exerts no direct effects on anti-CD3-stimulated T cells. In the presence of AC, however, rIL-1 augments T cell proliferation to anti-CD3. Recombinant IL-6 promotes T cell proliferation among T cells stimulated with polyvalent but not divalent anti-CD3. As deduced by Northern blot analysis, rIL-1 increases cytoplasmic levels of IL-6 mRNA in AC. Recombinant IL-6, in turn, amplifies the accumulation of stable IL-2 transcripts in purified T cells stimulated with polyvalent anti-CD3. Hence, IL-1, IL-6, and IL-2 support T cell proliferation through cascading effects at the level of gene transcription. The cytokines evaluated in this study, however, do not fully reconstitute AC functions in promoting anti-CD3 Mab T cell proliferation.

Abstract
Even though cyclosporin A (CsA) suppresses in vitro production of lymphokines such as interleukin 2 (IL 2) and responsiveness of cytotoxic T cell (CTL) precursors to IL 2, thereby inhibiting the in vitro generation of CTL, in vivo CsA does not affect the induction of alloreactive CTL. This paradox suggests that CsA-resistant signals are operating in vivo. Using an in vitro model system in which the requirement for antigen-presenting cells during primary activation of resting murine CD8 T cells is bypassed by immobilized anti-CD3 monoclonal antibodies, we here describe conditions in which IL 4 conveys CsA resistance to murine CD8 T cells triggered by immobilized anti-CD3 monoclonal antibodies to respond to IL 2. CsA resistance of IL 4 and IL 2-responsive CD8 T cell parallels conditions in which signals provided by IL 4 and IL 2 synergize with each other. CsA dissociates in vitro proliferative and differentiative events by suppressing the former while enhancing the latter. In addition to the known pleiotropic effects of IL 4, our results define an IL 4-dependent, CsA-resistant signal pathway which allows CTL differentiation in the absence of significant cell proliferation.
