Abstract
Asthma is a chronic lung disease affecting people of all ages worldwide, and it frequently begins in childhood. Because of its chronic nature, it is characterized by pathological manifestations, including airway inflammation, remodeling, and goblet cell hyperplasia. Current therapies for asthma, including corticosteroids and beta-2 adrenergic agonists, are directed toward relieving the symptoms of the asthmatic response, with poor effectiveness against the underlying causes of the disease. Asthma initiation and progression depends on the T helper (Th) 2 type immune response carried out by a complex interplay of cytokines, such as interleukin (IL) 4, IL5, and IL13, and the signal transducer and activator of transcription 6. Much of the data resulting from different laboratories support the role of poly(ADP-ribose) polymerase (PARP) 1 and PARP14 activation in asthma. Indeed, PARP enzymes play key roles in the regulation and progression of the inflammatory asthma process because they affect the expression of genes and chemokines involved in the immune response. Consistently, PARP inhibition achievable either upon genetic ablation or by using pharmacological agents has shown a range of therapeutic effects against the disease. Indeed, in the last two decades, several preclinical studies highlighted the protective effects of PARP inhibition in various animal models of asthma. PARP inhibitors showed the ability to reduce the overall lung inflammation acting with a specific effect on immune cell recruitment and through the modulation of asthma-associated cytokines production. PARP inhibition has been shown to affect the Th1–Th2 balance and, at least in some aspects, the airway remodeling. In this review, we summarize and discuss the steps that led PARP inhibition to become a possible future therapeutic strategy against allergic asthma.

Abstract
Poly(ADP-ribosyl)ation, catalysed by a family of poly(ADP-ribose) polymerases (PARPs), plays an important role in a large variety of physiological processes, including cell proliferation, but its role in cell cycle progression is not yet completely defined. As reported here, the examination of early times following serum stimulation of quiescent fibroblasts suggests that poly(ADP-ribosyl)ation is necessary for the transition from the G0 phase to the G1 phase. We show that PARP activity is involved in this step through the regulation of immediate-early response genes, such as c-Fos and c-Myc. This is supported by the finding that exogenous Myc expression substantially restores cell cycle reactivation in the absence of polymer synthesis. Furthermore, using RNA interference, we show that PARP-1 is the PARP family member playing the most prominent role in the upregulation of c-Fos and c-Myc during G0-G1 transition. We report that even in lectin-stimulated peripheral blood mononucleated cells, the inhibition of PARP activity interferes with the upregulation of immediate-early genes and delays the induction of proliferation, suggesting a general role for PARP-1 in linking growth factor signaling with cell cycle entry.

Abstract
Poly(ADP-ribose) polymerase-1 (PARP-1) catalyzes the rapid and extensive poly(ADP-ribosyl)ation of nuclear proteins in response to DNA strand breaks, and its expression, although ubiquitous, is modulated from tissue to tissue and during cellular differentiation. PARP-1 gene promoters from human, rat, and mouse have been cloned, and they share a structure common to housekeeping genes, as they lack a functional TATA box and contain multiple GC boxes, which bind the transcriptional activator Sp1. We have previously shown that, although Sp1 is important for rat PARP1 (rPARP) promoter activity, its finely tuned modulation is likely dependent on other transcription factors that bind the rPARP proximal promoter in vitro. In this study, we identified one such factor as NF1-L, a rat liver isoform of the nuclear factor 1 family of transcription factors. The NF1-L site on the rPARP promoter overlaps one of the Sp1 binding sites previously identified, and we demonstrated that binding of both factors to this composite element is mutually exclusive. Furthermore, we provide evidence that NF1-L has no effect by itself on rPARP promoter activity, but rather down-regulates the Sp1 activity by interfering with its ability to bind the rPARP promoter in order to modulate transcription of the rPARP gene.

Abstract
Poly(ADP-ribose) polymerase (PARP) is a nuclear enzyme which has been shown to play a role in the differentiation of haematopoietic cells. We report here that neutrophils are the first nucleated mammalian cell type demonstrated to be devoid of immunoreactive PARP. Both NB4 acute promyelocytic leukaemia and HL-60 (acute myelocytic leukaemia) cells were differentiated into non-malignant neutrophils with all-trans-retinoic acid (ATRA). Western blot analysis demonstrated that ATRA had no effect on PARP expression in HL-60 cells. However, PARP was completely down-regulated in NB4 cells within 36 h of treatment initiation. This decrease in PARP polypeptide coincided with growth arrest and preceded the appearance of neutrophilic differentiation features. NB4 cells require a combination of 1,25-dihydroxyvitamin D3 (1,25-D3) and phorbol 12-myristate 13-acetate (PMA) to differentiate completely into monocyte/macrophages, whereas HL-60 cells can be made to differentiate by combined or single agents. PARP expression was up-regulated 90-fold when NB4 cells were treated with PMA and 1,25-D3 together, and this increase accompanied expression of the monocyte/macrophage phenotype. Only modest changes in PARP expression were observed when each agent was used alone in NB4 cells or when HL-60 cells were differentiated along the monocyte/macrophage pathway. In addition, PARP activity was modulated in a pattern similar to protein levels when NB4 cells were induced to differentiate along the neutrophilic and monocyte/macrophage pathways. This suggests that the activity of PARP may be controlled through regulation of protein levels during NB4 cell differentiation. We conclude that PARP levels are dramatically modulated during monocyte/macrophage and neutrophilic differentiation. On the basis of the tremendous changes in PARP polypeptide and total activity during myeloid differentiation, we propose that modulation of PARP gene expression is required for cellular maturation in both lineages.

Abstract
6(5H)-phenanthridinone, a recently identified poly(ADP-ribose)polymerase (PARP) inhibitor, is able, at micromolar concentrations, to inhibit concanavalin A-induced lymphocyte proliferation and to potentiate the effect of gamma radiation upon murine spleen cells. When added at the onset of a mixed lymphocyte culture, this compound strongly depresses the induction of primary allogeneic (anti-H2k) cytotoxic T-lymphocytes (CTLs). Lymphokine-activated killer (LAK) induction was also found to be impaired by the PARP inhibitor. Taken together, these results clearly indicate that PARP plays a key-role in immune reactions involving cytotoxicity and that 6(5H)-phenanthridinone could be considered as a potent immunomodulator.

Abstract
Rheumatoid arthritis (RA) synovial fluid (SF) T cells express the activation markers CD69, HLA-DR and very late antigen (VLA)-1, but surprisingly few bear interleukin-2 receptors (CD25). This unusual activation state is commonly assumed to be due to stimulation by local antigen, yet T cells activated in vitro express activation antigens in the clearly defined sequence: CD69, CD25, HLA-DR and finally VLA-1. Two possible explanations for the activation state of SF cells are: first, they comprise several subpopulations each expressing different activation antigens or, second, activation markers are up-regulated by mechanisms other than antigen stimulation. To examine these hypotheses, double- and triple-color immunofluorescence techniques were applied to four T cell populations: normal peripheral blood T cells activated in vitro, RA SF T cells, T cells from an in vivo model of migration [tuberculin purified protein derivative (PPD)-induced skin blisters] and T cells co-cultured with endothelial cells (EC). The results confirmed that in vitro activated T cells expressed activation markers in the sequence described above, with significant CD25 expression and few cells co-expressing CD69 with HLA-DR or VLA-1. In contrast, almost half the SF T cells were CD69+HLA-DR+ but CD25-; a significant minority were CD69+VLA-1+. T cells from PPD-induced skin blisters were already HLA-DR+ and VLA-1+ at 24 h, although, in vitro, PPD-activated T cells up-regulated HLA-DR and VLA-1 only after 1 week, suggesting that pre-activated T cells were preferentially recruited into the blisters. Finally, T cells were found to up-regulate CD69 and, to a lesser extent, HLA-DR after adhering to EC in vitro. In summary, the paradoxical activation state of SF T cells cannot be explained solely by single or multiple rounds of activation in situ. At least two other mechanisms, the preferential recruitment of pre-activated T cells and the induction of HLA-DR and especially CD69 by endothelial contact during migration, may also play a role.

Abstract
The activity profile of poly(ADP-ribosyl)transferase was assayed during a complete cell cycle of rat thymocytes stimulated in the presence of interleukin-2 by concanavalin A or monoclonal antibodies against the T-cell antigen receptor (TCRmAB). Poly ADP-ribosylation was measured in permeabilized cells by the incorporation of [adenine-3H]NAD+ into protein bound poly ADP-ribose. The polymers of ADP-ribose were separated from the monomers using dihydroxyboronyl-Bio-Rex 70 columns. The rate of poly(ADP-ribosyl)ation increases during the G1 phase with a maximum 12 h after stimulation. This increase in activity is due to enhanced de novo synthesis of poly(ADP-ribosyl)transferase which can be abolished by the addition of cycloheximide. The half-life of this enzyme during the induction period was estimated to be 4 h. A second activity peak appears during the S-phase of the cell cycle 48 h after stimulation. The maxima of the poly(ADP-ribosyl)ation rate coincide with elevated immunoreactive enzyme levels at 12 and 48 h of culture assayed by Western blotting. The mRNA levels of pADPRT do not correlate with the first maximum of activity, whereas the second maximum was accompanied by a 5-fold increase of the specific mRNA. These results suggest a translational regulation of pADPRT in the G1 phase of the cell cycle, whereas the second activity peak in the S-phase is due to an increased transcription and translation. The induction of pADPRT activity in the G1 phase of TCRmAB-stimulated cells points to a function of poly(ADP-ribosyl)ation in the proliferation of thymocytes.
