Abstract
Various cytokines have in the past been detected in human skin. Among these, the neutrophil-activating peptide NAP-1/IL-8 is a potent 8-kD proinflammatory peptide that has been purified from psoriatic scales. Its chemotactic activity on human neutrophils, as well as its presence in psoriatic scales, may relate to a role in this disease. In the present study, the tissue distribution of the peptide was examined immunohistochemically using two monoclonal antibodies (52E8, 46E5) recently produced and characterized in our laboratory. Immunoreactivity was detected in both normal and psoriatic skin, resulting in uniform suprabasal keratinocyte staining in normal skin with 52E8 and of all keratinocytes with 46E5. Immunoreactivity in psoriasis correlated to the inflammatory tissue reaction, varying from uniform absence in highly active psoriasis to focally weak staining in plaque type psoriasis. Cells of the acrosyringium and hair follicles were always positive and were unaffected by the inflammatory activity. Epidermal immunoreactivity detected in this study may be associated with closely related peptides of the IL8 family or with truncated or extended forms of NAP-1/IL-8.

Abstract
An inflammatory reaction was induced in vivo by injection of zymosan into the peritoneal cavity of the rabbit. The inflammatory exudate was found to contain oedema-inducing and neutrophil chemoattractant activity when assayed in rabbit skin in vivo, using 125I-albumin and 111In-neutrophils. This activity was additional to that of complement fragment C5a, which was removed by an affinity gel. Two chemoattractants were isolated by cation-exchange, gel-filtration and reversed-phase h.p.l.c. One of these, which ran as a single band of 6-8 kDa on SDS/PAGE, was subjected to N-terminal sequence analysis without reduction and alkylation of cysteine residues. Positive identification of 28 of the first 31 amino acids revealed a rabbit homologue of interleukin-8 (75% sequence identity with human interleukin-8). The demonstration of interleukin-8 as a major neutrophil chemoattractant in an inflammatory reaction in vivo provides the basis for further investigations into the role of this cytokine in the inflammatory process.

Abstract
Melanoma growth-stimulatory activity (MGSA), a peptide reported to be mitogenic for Hs294T human melanoma cells, has extensive sequence similarity to the neutrophil-activating peptide NAP-1/IL-8, suggesting functional similarities. To test this hypothesis, MGSA was chemically synthesized and tested for its effects on human neutrophils. It was found to induce chemotaxis, exocytosis of elastase, and changes in cytosolic-free calcium to an extent and at concentrations similar to NAP-1/IL-8. However, MGSA was considerably less potent than NAP-1/IL-8 in inducing the respiratory burst. Intradermal injections in rats of MGSA resulted in a massive accumulation of neutrophils. Our data demonstrate that, apart from its growth-stimulatory activity, MGSA is a potent inflammatory agonist with neutrophil-stimulating properties.

Abstract
The cytokine NAP-1/IL-8 is produced by a variety of different cells in response to inflammatory stimuli and elicits several biological responses from PMN. Experiments presented here demonstrate that PMN exposed to NAP-1/IL-8 expressed increased amounts of CD11b/CD18, as well as CD11c/CD18 and CR1, on their cell surface, while expression of Fc gamma RIII and HLA-A,B,C remained essentially unchanged. Increased CD11b/CD18 and CD11c/CD18 appears to correspond with the release of specific granules by NAP-1/IL-8. NAP-1/IL-8 was also a potent stimulator of several of the binding activities of CD11b/CD18. Ligation of EC3bi by CD11b/CD18 was rapidly enhanced by NAP-1/IL-8, but phagocytosis of the ligated particles was not induced by the agonist. In addition, enhanced binding of EC3bi was observed in the absence of an increase in receptor expression as shown with PMN cytoplasts. NAP-1/IL-8 promoted additional adhesive interactions between CD11b/CD18 and the biosynthetic precursor of LPS, lipid IVa, fibrinogen, and endothelial cells, suggesting that NAP-1/IL-8 may promote leukocyte adhesion in vivo that could lead to recruitment of PMN to sites of tissue inflammation.

Abstract
We studied the origin of the neutrophil-activating peptide NAP-2, a presumed 70 amino acid cleavage product of platelet basic protein (PBP) and connective tissue-activating peptide III (CTAP-III). Purified human blood monocytes or lymphocytes were cultured with or without stimuli (LPS or PHA) in the presence or absence of platelet-release supernatant, and the formation of NAP-2 and other neutrophil-activating peptides was monitored. NAP-2 was generated whenever monocytes and platelet release supernatant were present. When a monocyte stimulus was added, NAF/NAP-1 was also formed, and in the presence of LPS a third, less potent neutrophil-stimulating fraction, consisting of NAP-2 variants with 73, 74, and 75 residues, also appeared. Monocytes alone did not yield NAP-2 and no neutrophil-activating peptide was generated by lymphocytes. The monocyte-conditioned medium was found to cleave purified CTAP-III into NAP-2 through proteinases that were highly sensitive to PMSF, moderately sensitive to leupeptin and insensitive to EDTA.

Abstract
The first part of the review outlines the classical interpretation of radiation damage to normal organs based on dose-response relationships for clonogenic cell survival and tissue kinetics. Proliferative organization of critical cell lineages (three-compartmental or H-type and one-compartmental or F-type) is considered as an additional determinant in the development of overt radiation injury. This leads to testable predictions concerned with divergent outcomes of stimulation of cell proliferation after radiation exposure using polypeptide growth factors. The prediction of favourable effects of such stimulation in H-type lineages is borne out by recent experiments on treatment with cytokines of radiation-induced haemopoietic insufficiency. The second prediction of deleterious effects of proliferative stimulation in recently, heavily irradiated F-type cell lineages remains to be verified or refuted.

Abstract
Certain inflammatory stimuli render cultured human vascular endothelial cells hyperadhesive for neutrophils. This state is transient and reversible, in part because activated endothelial cells secrete a leukocyte adhesion inhibitor (LAI). LAI was identified as endothelial interleukin-8 (IL-8), the predominant species of which is an extended amino-terminal IL-8 variant. At nanomolar concentrations, purified endothelial IL-8 and recombinant human IL-8 inhibit neutrophil adhesion to cytokine-activated endothelial monolayers and protect these monolayers from neutrophil-mediated damage. These findings suggest that endothelial-derived IL-8 may function to attenuate inflammatory events at the interface between vessel wall and blood.

Abstract
Recent advances in cellular and molecular biology have provided important new avenues to assess mechanisms of granuloma formation/regulation. For example, current studies have identified various cytokines that can exert a powerful influence on both immune and non-immune cells and dictate inflammatory processes. Some of these cytokines are potentially active during the initiation and maintenance of chronic inflammation, including tumor necrosis factor, interleukin 1, and a novel class of chemotactic cytokines. This latter group of mediators belongs to a super-gene family of immune signals that play a key role in the selective recruitment of inflammatory cells to an area of inflammation. The coordinated synthesis of these cytokines is likely important to the development of the granulomatous response. The participation of molecular signals produced by non-inflammatory cells, fibroblasts, and epithelial cells, also warrants special consideration. These "bystander" cells appear to possess effector cell functions and likely serve an important role in inducing pulmonary granulomatous inflammation. Thus, a clear understanding of the cells and molecular signals involved in the initiation and maintenance of chronic pulmonary inflammation will be necessary to assess lesion development and design more selective/effective therapies.

Abstract
IgE-independent mediator release from basophils is considered an important event in inflammation, particularly in nonallergic immediate hypersensitivity and in allergic late-phase reactions. This study demonstrates that after exposure to IL-3, basophils release histamine and leukotrienes in response to the neutrophil-activating peptide NAF/NAP-1. Thus, the sequential action of two pure cytokines can promote basophils mediator release. In the presence of IL-3, NAF/NAP-1 functions like a "histamine-releasing factor" and may therefore not only induce cellular infiltration but also provoke symptoms of hypersensitivity reactions.

Abstract
A cDNA library was constructed from HL60 human promyelocyte poly(A)+ RNA harvested 3 h after induction of macrophage differentiation with 12-O-tetradecanoyl phorbol-13-acetate in the presence of cycloheximide. We isolated from this library a 1.6-kilobase full-length clone designated b4 whose corresponding mRNA was greatly increased in abundance in cytoplasmic RNA under these conditions. Dideoxy sequencing revealed that this mRNA encoded MONAP (monocyte-derived neutrophil-activating peptide), a 10-kilodalton monokine with neutrophil-specific chemotactic and enzyme-releasing activities. The 3' untranslated region of this mRNA was found to be 1.2 kilobases long and possessed nine copies of the AUUUA sequence known to be associated with regulation of mRNA stability. Actinomycin D chase experiments yielded evidence that cytoplasmic stabilization was one of the means of regulation of MONAP expression. Analysis of cytoplasmic poly(A)- RNA revealed the presence of several discrete truncated species that shared a common 5' end and appeared to be intermediates of degradation. S1 mapping showed that the 3' ends of these molecules were distributed throughout the 3' untranslated region, preferentially in A + U-rich regions, broadly correlating with the distribution of AUUUA sites. Nuclear run-on experiments indicated that transcriptional induction accounted for less than 15% of the accumulation of MONAP mRNA. This mRNA was induced in HL60 cells by treatment with several differentiation-inducing agents: 12-O-tetradecanoyl phorbol-13-myristate alone, sodium butyrate, vitamin D3, and dimethyl sulfoxide. It was also induced in quiescent diploid lung fibroblasts stimulated to divide by serum, and it was constitutively overexpressed by some human tumor lines.

Abstract
So far, the role of fibroblasts in inflammatory processes has been underestimated. We have previously shown that stimulation of fibroblasts with viruses or bacteria results in a simultaneous production of several cytokines, including interferon-beta, interleukin (IL) 6 and colony-stimulating factors. We here report that virally infected fibroblasts produce also a chemotactic factor for granulocytes. The activity is inducible not only by measles virus but also by IL 1 beta and the double-stranded RNA poly(rI).poly(rC). This factor, when purified to homogeneity, occurs as a 6-7-kDa protein doublet upon sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The pure protein is serologically related to a fully characterized granulocyte chemotactic peptide (GCP) from monocytes, designated IL8. Furthermore, the chemotactic factor from fibroblasts has an NH2-terminal sequence identical to that of GCP/IL8, small differences in NH2-terminal processing being observed. Finally, in addition to diploid fibroblasts, the osteosarcoma MG-63 cell line is also a producer of GCP/IL8. It can thus be concluded that GCP/IL8 can be produced by several cell types in response to infection and that fibroblasts can contribute to chemotaxis in inflammation.

Abstract
Granulocyte chemotactic protein/Interleukin-8 (GCP/IL-8), purified to homogeneity from endotoxin- or mitogen-stimulated human mononuclear cells, was injected intradermally into rabbits to evaluate the proinflammatory properties of this novel cytokine. In the presence of a vasodilator substance, pmol amounts of GCP/IL-8 induced neutrophil accumulation that was fast in onset, relatively short of duration (half life 60 to 70 minutes), and was associated with a parallel time course of plasma protein extravasation. GCP/IL-8-induced edema formation was found to be neutrophil dependent. These data provide evidence that GCP/IL-8 fulfills two important criteria for consideration as an inflammatory mediator. It is possible that endogenous GCP/IL-8, if produced locally by tissue macrophages, may contribute to the initiation of the inflammatory response to infection.

Abstract
A novel neutrophil-activating peptide was recently characterized by different laboratories and named NAF (neutrophil-activating factor) (Walz et al., 1987) MDNCF (monocyte-derived neutrophil chemotactic peptide) (Yoshimura et al., 1987) and MONAP (monocyte-derived neutrophil-activating peptide) (Gregory et al., 1988). The peptide detected in the culture fluids of stimulated human mononuclear phagocytes consists of 72 amino acids. Minor amino-terminal truncation variants are also found (Lindley et al., 1988). The major form was now obtained by recombinant methods and was shown to be biologically equivalent to purified natural NAF (Lindley et al., 1988).

Abstract
Neutrophil-activating factor (NAF), a 72-amino acid peptide produced by human monocytes, induced plasma leakage and neutrophil accumulation after intradermal injection in rabbits (10(-11) to 10(-9) mol/site). NAF was about three times more potent than fMet-Leu-Phe, but considerably less potent than endotoxin. The response to NAF was not inhibited by the endotoxin inhibitor polymyxin B or the protein synthesis inhibitor actinomycin D. Histology of NAF-induced lesions showed large numbers of neutrophils, but no monocytes, eosinophils, basophils, or lymphocytes were observed. Intravascular neutrophil accumulation, aggregate formation, and venular wall damage were also apparent. In vitro, NAF stimulated rabbit neutrophils as shown by the release of N-acetyl-beta-glucosaminidase. This study demonstrates that NAF elicits a rapid inflammatory response in vivo with massive neutrophil emigration, which is qualitatively similar to that observed with other chemotactic agonists.
