Abstract
Chemokines and cytokines are critical for initiating and coordinating the organized and sequential recruitment and activation of cells into Mycobacterium tuberculosis-infected lungs. Correct mononuclear cellular recruitment and localization are essential to ensure control of bacterial growth without the development of diffuse and damaging granulocytic inflammation. An important block to our understanding of TB pathogenesis lies in dissecting the critical aspects of the cytokine/chemokine interplay in light of the conditional role these molecules play throughout infection and disease development. Much of the data highlighted in this review appears at first glance to be contradictory, but it is the balance between the cytokines and chemokines that is critical, and the "goldilocks" (not too much and not too little) phenomenon is paramount in any discussion of the role of these molecules in TB. Determination of how the key chemokines/cytokines and their receptors are balanced and how the loss of that balance can promote disease is vital to understanding TB pathogenesis and to identifying novel therapies for effective eradication of this disease.

Abstract
Mouse secretory leukocyte protease inhibitor (SLPI) was recently characterized as a lipopolysaccharide (LPS)-induced product of macrophages that antagonizes their LPS-induced activation of NF-kappaB and production of NO and tumor necrosis factor (TNF) (F. Y. Jin, C. Nathan, D. Radzioch, and A. Ding, Cell 88:417-426, 1997). To better understand the role of SLPI in innate immune and inflammatory responses, we examined the kinetics of SLPI expression in response to LPS, LPS-induced cytokines, and LPS-mimetic compounds. SLPI mRNA was detectable in macrophages by Northern blot analysis within 30 min of exposure to LPS but levels peaked only at 24 to 36 h and remained elevated at 72 h. Despite the slowly mounting and prolonged response, early expression of SLPI mRNA was cycloheximide resistant. Two LPS-induced proteins-interleukin-10 (IL-10) and IL-6-also induced SLPI, while TNF and IL-1beta did not. The slow attainment of maximal induction of SLPI by LPS in vitro was mimicked by infection with Pseudomonas aeruginosa in vivo, where SLPI expression in the lung peaked at 3 days. Two LPS-mimetic molecules-taxol from yew bark and lipoteichoic acid (LTA) from gram-positive bacterial cell walls-also induced SLPI. Transfection of macrophages with SLPI inhibited their LTA-induced NO production. An anti-inflammatory role for macrophage-derived SLPI seems likely based on SLPI's slowly mounting production in response to constituents of gram-negative and gram-positive bacteria, its induction both as a direct response to LPS and as a response to anti-inflammatory cytokines induced by LPS, and its ability to suppress the production of proinflammatory products by macrophages stimulated with constituents of both gram-positive and gram-negative bacteria.

Abstract
The multifunctional cytokine interleukin-6 (IL-6) plays a central role in host defence mechanisms and hematopoiesis. Furthermore, dysregulation of IL-6 gene expression is associated with the pathogenesis of various immunologically related diseases such as myeloma, systemic lupus erythematosus, rheumatoid arthritis, psoriasis and Kaposi's sarcoma. The regulation of IL-6 gene expression occurs mainly at transcriptional level, although mechanisms of post-transcriptional regulation have also been described. In the present study we demonstrate that in HeLa cells, induction of IL-6 by interferon-gamma (IFN-gamma) is transcriptionally controlled, as shown by run on assays and analysis of the IL-6 mRNA stability. Gel-retardation experiments using antibodies specific for factors of the IRF family identified four protein-DNA complexes, which bind to the interferon regulatory factor (IRF) binding site at position -267 to -254, in nuclear extracts from IFN-gamma treated cells. Furthermore, transient transfection analyses of the 5'-flanking region of IL-6 gene linked to the chloramphenicol acetyltransferase (CAT) reporter gene demonstrated that the -267 to -254 IRF site is necessary for IL-6 induction by IFN-gamma. However, transfection experiments in which IRF-1 and I kappa B alpha were overexpressed show that full-scale transcriptional activation of the IL-6 promoter directing CAT expression requires the co-operation between IRF-1 and NF-kappa B at a low constitutive level.

Abstract
Previous studies have demonstrated that alveolar macrophages from lung cancer patients are impaired in their ability to develop tumoricidal function when stimulated by activators such as interferon gamma + lipopolysaccharide. However, these same macrophages have been shown to develop significant tumoricidal function when precultured with macrophage-depleted allogeneic peripheral blood lymphocytes from normal donors, an effect that was lost by the elimination of natural killer cells from the allogeneic lymphocyte population. In the present study, the effect of each activation condition on the expression of mRNA for interleukin-1 alpha (IL-1 alpha), IL-1 beta, tumor necrosis factor alpha (TNF alpha) and IL-6 was determined using reverse transcription/polymerase chain reaction. The results show that the non-permissive activation condition is associated with the expression of mRNA for IL-6 while the permissive activation condition is not. Antibodies against IL-6 were subsequently shown to permit the development of tumoricidal function in alveolar macrophages stimulated with interferon gamma + lipopolysaccharide while IL-6 protein was shown to inhibit the stimulatory action of allogeneic lymphocytes on the development of tumoricidal function in the same alveolar macrophages. Neither the permissive (i.e. allogeneic lymphocyte stimulation) nor the non-permissive (i.e. interferon gamma + lipopolysaccharide) activation condition had any effect on the capacity of alveolar macrophages from lung cancer patients to express mRNA for IL-1 alpha, IL-1 beta or TNF alpha. These results show that IL-6 can regulate the ability of alveolar macrophages from lung cancer patients to be stimulated by interferon gamma + lipopolysaccharide to develop significant tumoricidal function. They also show that allogeneic lymphocytes have the capacity to down-regulate IL-6 mRNA synthesis by alveolar macrophages thereby permitting the development and/or expression of macrophage tumoricidal function.

Abstract
Cyclosporin A (CsA) administration reduced mortality in mice sensitized to endotoxic toxicity by various agents, such as muramyl dipeptide (MDP) or a lipophilic derivative. CsA is an inhibitor of a variety of T cell responses, suggesting that muramyl peptides could influence LPS-induced effects via the release of lymphokine. The potentiation of TNF production by pretreatment with muramyl peptides was comparable in nude mice and in controls, indicating that it is a T-independent mechanism, and CsA produced a similar inhibition in both groups. Neutralizing antibody to IFN-gamma did not change the elevated TNF level obtained in the blood when LPS was given after a muramyl peptide. However, the same treatment with anti-IFN-gamma MAb prevented the death of mice challenged with LPS plus MDP or plus a lipophilic derivative displaying similar effects. In comparing three selected muramyl peptides, we also show that the priming effect could be dissociated from the toxic synergism with LPS.

Abstract
Cytokines secreted from antigen-specific T lymphocytes provide important positive and negative control of inflammation through their effects on non-antigen-specific inflammatory leukocytes. These effects often involve modulation of gene expression. Lymphokine-inducible macrophage gene expression is largely controlled at the level of transcription. Multiple cis-acting sequence motifs cooperate with one another to produce patterns of expression that are relatively unique to individual genes. Members of trans-acting transcription factor families, which recognize related regulatory sequence elements, participate frequently in complex protein-protein interactions that generate remarkable complexity in terms of the number of potential combinations and the consequential functional differences exhibited by each combination. Thus, the remarkable plasticity of immune-mediated inflammation derives from combinations of finite numbers of options at several points in the cellular and molecular sequence.

Abstract
Prenatal exposure to diazepam leads to a suppression of mitogen or allogen-induced lymphocyte proliferation as well as to a reduced production of tumour necrosis factor (TNF)-alpha from rat splenocytes during postnatal development of rats. We analysed the secretion of interleukin (IL)-6 which occurs at a later stage of the cytokine cascade. Splenocytes of male offspring from Long Evans rats, treated with a daily dose of diazepam (1.25 mg/kg) from gestational day 14 to 20, were stimulated with lipopolysaccharide (LPS) and concanavalin A (Con A). In response to LPS, IL-6 liberation was significantly lower in mixed splenocytes and spleen macrophages of 2 and 8 week old prenatally diazepam-treated rats than in controls. Spleen lymphocyte preparations of prenatally treated animals exhibited a reduction of IL-6 release at 12 h and an increase at 24 h of incubation. At 2 weeks of age, Con A-induced IL-6 production could only be detected in mixed splenocytes; prenatally treated rats were releasing significantly less IL-6 than controls. In 8 week old rats, IL-6 liberation from mixed splenocytes and spleen macrophages was significantly lower in prenatally treated animals than in controls. Spleen lymphocytes presented a complex response picture depending upon incubation conditions. Our data indicate that in prenatally diazepam-exposed rats, the disturbance of cytokine release also extends to cytokines which play an important role in the later phases of immune responses.

Abstract
To study the effect of interferon gamma (IFN-gamma) on the expression of the retinoblastoma (RB) susceptibility gene, we performed Northern-blot analysis on RNA extracted from Wish, HEL and monocytoid cell lines U-937 and THP-1 treated with 1,000 IU/ml of recombinant IFN-gamma. In U-937 and THP-1 cells, IFN-gamma increased the abundance of RB mRNA. In Wish and HEL cells, co-treatment with cycloheximide was required for IFN-gamma to increase the level of RB mRNA. Pre-treatment of THP-1 cells with cycloheximide prior to IFN-gamma treatment augmented the effects of IFN-gamma on RB gene expression. The effect of IFN-gamma in THP-1 cells was observed after 3 hr of treatment, being more pronounced after 6 hr and persisting until at least 18 hr, although at a lower level. These results suggest that IFN-gamma regulates the level of RB mRNA by different mechanisms in the different cell types. This cytokine increases the abundance of RB mRNA in monocytoid cell lines, reinforced by prior treatment with cycloheximide. Inhibition of protein synthesis is required in Wish and HEL cell lines before IFN-gamma has an effect on RB gene expression.

Abstract
Sarcoidosis is a chronic granulomatous disease that may be considered to be a human model for the delayed-type hypersensitivity reaction. The expression of cytokine genes in organs displaying sarcoid granulomas was analyzed by in situ hybridization with several cytokine probes using biopsies from 11 sarcoid lymph nodes. We detected cells expressing interleukin-1 beta (IL-1 beta), tumor necrosis factor-alpha (TNF-alpha), IL-6, IL-2, and interferon-gamma (IFN-gamma) genes in all lymph nodes. The major finding of this study was that cytokine genes are independently expressed. Of the monokine genes, the IL-1 beta gene was preferentially expressed. The distribution of cells containing IL-1 beta mRNA was characterized by their amalgamation in clusters inside sarcoid granulomas. Cells expressing the TNF-alpha gene were located exclusively inside granulomas and were always scattered. Cells expressing the IL-6 gene or the IL-1 alpha gene were found scattered inside sarcoid granulomas and in the residual lymphoid tissue. The number of cells expressing the IL-1 beta gene was significantly higher than that of cells expressing TNF-alpha gene (P = .001), IL-6 gene (P = .007), or IL-1 alpha gene (P less than .001). Of the cells expressing lymphokine genes, those expressing the IFN-gamma gene were 31.9 (+/- 7.6) times more frequent than those expressing the IL-2 gene (P less than .001). Cells containing IFN-gamma mRNA were detected mainly inside sarcoid granulomas, whereas cells containing IL-2 mRNA were randomly distributed. These results show that each monokine gene or lymphokine gene can be independently expressed in vivo. The high expression level of the IL-1 beta gene and the IFN-gamma gene inside granulomas may be specific to delayed-type hypersensitivity immune reactions.

Abstract
C57BL/6, BALB/c, and CBA mice were infected either by Mycobacterium bovis BCG or by M. lepraemurium (MLM). Interleukins (IL) 2, 4 and 6 and interferon-gamma (IFN-gamma) were measured in the supernatants of draining lymph node cells (DLN) or control lymph node cells from uninfected mice, restimulated in vitro by the heat-killed infecting Mycobacterium. Uninfected lymph node cells did not develop any IL4, IL2, and IFN-gamma response to BCG and MLM. A significant IL6 response to BCG was observed, with CBA being the best producer and C57BL/6 the weakest. BCG-infected mice, which controlled the BCG infection, displayed variable patterns of lymphokine response to BCG according to the strain. C57BL/6 DLN cells produced more IL6 and IFN-gamma than IL2, whereas BALB/c mice produced more IL2. CBA secreted lymphokines with a similar pattern to that of BALB/c but in lower amounts. IL4 was not detected in any supernatant. MLM-infected mice displayed variable susceptibilities to MLM infection: C57BL/6 was resistant, BALB/c was susceptible after an initial efficient control, and CBA was fully susceptible. In each strain the lymphokine response to MLM was much lower than that triggered by BCG, but the pattern was similar. Thus, C57BL/6 DLN cells still produced significants amounts of IL2, IL6, and IFN-gamma, whereas BALB/c secreted IL2 alone and CBA did not produce any detectable lymphokine. IL4 was again not detected in any supernatant. The failure of BALB/c and CBA strains to develop IFN-gamma and IL6 responses to MLM might contribute to their low resistance to this infection.

Abstract
In the present report we compare the capacity of two related cytokines, tumor necrosis factor (TNF) alpha and lymphotoxin (LT), to modulate mRNA levels of interleukin-6 (IL-6) in cells representing different stages of monocytic differentiation including the human leukemia cell lines HL 60, U 937, THP-1, MonoMac 1 and peripheral blood monocytes. We show that the capacity of TNF alpha and LT to induce IL-6 mRNA accumulation increases as monocytic differentiation proceeds with TNF alpha being more potent than LT, suggesting that alternate pathways may be used by differentiating cells to control expression of IL-6. In contrast, in monocytes which constitutively synthesize IL-6 transcripts, TNF alpha and LT treatment had opposite effects on levels of IL-6 mRNA accumulation. In these cells TNF alpha enhanced steady state levels of IL-6 transcripts due to mRNA stabilization, whereas LT shortened IL-6 mRNA half-life, most likely due to induction of a RNA destabilizer since LT-mediated downregulation of levels of IL-6 mRNA in monocytes could be prevented by inhibition of protein synthesis. Neither TNF alpha nor LT altered IL-6 mRNA accumulation by interfering with preexisting transcription factors since both TNF alpha and LT required de novo protein synthesis to exert their effects.
