Abstract
This work describes the production of lipases from endophytic fungi: Vermisporium-like, Emericella nidulans, Dichotomophtora portulacae and D. boerhaaviae and the biological activity against the dermatophyte fungi Malassezia sp and Microsporum canis and the parasite Leishmania amazonensis. All fungal enzymes extract showed lipolysis action in the media that contains long carbon chain lipids. The proteomic analysis of lipases exhibits several molecules mostly ranging in size from 220 to 20 kDa, with clear differences in protein profile's yield. All fungal enzymes were competent to eliminate promastigote forms of Leishmania amazonensis at 5 mg.mL-1. The antileishmanial activity of lipases from Vermisporium-like, E. nidulans, D. portulacae and D. boerhaaviae in amastigote forms, promoted the reduction in viability of 78.88, 39.65, 63.17 and 98.13%, with selectivity index of 19.56, 30.68, 18.09 and 20.99. In relation to antifungal activity, Dichothomophtora enzymes demonstrate best action with MFC of 14.65 μg.mL-1 against Malassezia sp and Microsporum canis, respectively. These results allow us to infer that lipases from entophytic fungi displays activity against dermatophyte fungi (Malassezia sp. and Microsporum canis) as well as Leishmania.

Abstract
Natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) kill target cells by the granule-exocytosis pathway and by the engagement of molecules belonging to the tumor necrosis factor family. The involvement of secretory phospholipase A(2) (sPLA(2)) in the cytotoxic process has been proposed in NK cells. However, its molecular identity and intracellular localization remain unknown, and its mechanism of action is poorly understood. Here, we have readdressed this issue by studying the cytotoxic activity of whole cell extracts of a CTL line. We observed that inactivation of the perforin-granzyme pathway at 37 degrees C in the presence of 1 mM Ca(2+) enhanced the ability of CTL extracts to induce apoptosis. This potentiation of cell death was Ca(2+)-dependent, thermo-resistant, and inhibited by 4-bromophenacyl bromide and scalaradial (two inhibitors of sPLA(2)). The involvement of an sPLA(2) was confirmed by blocking the pro-apoptotic activity of the Ca(2+)-treated cell extract with an anti-sPLA(2) polyclonal antibody. By cell fractionation assays, we showed that the pro-apoptotic sPLA(2) was localized in the cytoplasmic fraction but not in perforin-rich granules or plasma membrane fractions. Western blotting analysis revealed the presence of four distinct bands of 56, 29.5, 21, and 15 kDa. The highest molecular weight band was consistent with the expression of a group III sPLA2. Taken together, these data indicate that an apoptosis-inducing sPLA(2) is expressed in the cytosol of a CTL cell line and suggest that it plays an effector role in CTL-mediated cytotoxicity.

Abstract
It has been shown recently that different genotypes of Mycobacterium tuberculosis induce distinct immune responses in the host, as reflected by variations in cytokine and iNOS expression. Because these molecules are probably regulated by multiple factors in vivo this complex phenomenon was partially analysed by assessing cytokine and iNOS expression by real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) in an in vitro model of bone marrow-derived macrophages infected with three different M. tuberculosis genotypes: Canetti, H37 Rv and Beijing. Although the three genotypes induced production of iNOS and the different cytokines tested at 24 h post-infection, macrophages infected with the Beijing isolate expressed the highest levels of mRNA for iNOS, interleukin (IL)-1beta, tumour necrosis factor (TNF)-alpha, IL-12 cytokines and lower levels of IL-10 compared with cells infected with other genotypes. This expression pattern has been associated with infection control, but during infection in vivo with the Beijing genotype it is lost upon progression to chronic phase. The failure to control infection is likely to be influenced by cytokines produced by other cell types and bacterial molecules expressed during the course of disease. Results presented in this work show that each genotype has the ability to induce different levels of cytokine expression that could be related to its pathogenesis during infection.

Abstract
Purified fractions from a fetal sheep liver extract (FSLE) were investigated, in a murine model, for induction of leukocyte stimulating activities. The fractions FSLE-1 and FSLE-2 induced splenocyte proliferation in vitro in C57Bl/10ScSn (LPS responder) mice comparable to LPS, and in C57Bl/10ScCr (LPS non responder) mice. They also stimulated the release of nitrogen radicals in bone marrow-derived macrophages (BMDM) from several mouse inbred strains including both C57Bl/10ScSn and C57Bl/10ScCr mice. Stimulation of NO production could be blocked by L-NMMA, an inhibitor of iNOS, and enhanced by the simultaneous addition of IFN-gamma. Moreover, stimulation of macrophages by FSLE-1 and FSLE-2 induced a cytostatic effect of the activated macrophages for Abelson 8-1 tumor cells. The stimulatory activity of the purified fractions is partially due to trace amounts of LPS derived from the fetal liver extract which was enriched during purification. Our results may help to explain the beneficial effect of the extract in patients which has been observed clinically.

Abstract
Abstract
Macrophages (Mφ) play essential roles both in tumor defense and normal tissue homeostasis by removal of transformed as well as damaged and disintegrating cells. Whereas tissue necrosis is known to provoke inflammatory responses, removal of apoptotic cells has been assumed to be immunologically inert. We now show that while Mφ exposure to necrotized tumor cells causes pronounced stimulation of Mφ antitumor activity, exposure of Mφ to apoptotic tumor cells in contrast results in impairment of Mφ-mediated tumor defense and even support of tumor cell growth. Given the fact that apoptosis is a consequence of various cancer treatment modalities, this may lead to a suppression of local antitumor reactions and thus actually counteract endogenous immune-mediated tumor defense mechanisms.

Abstract
Macrophages constitute a major part of natural tumor defense by their capacity to destroy selectively a broad range of tumor types upon specific activation. In the last couple of years, these cells have also been implicated as effector cells in the destruction of tumors by photodynamic therapy. In the present work, the potential role of macrophage-mediated tumor cytotoxicity after photodynamic treatment in vitro has been investigated with respect to photodynamic activation of macrophages for tumoricidal effector functions. Our data show that photodynamic treatment of highly pure murine bone-marrow-derived macrophages with the hematoporphyrin derivative Photosan-3 does not result in activation of these cells for cytotoxicity against YAC-1 tumor cells or secretion of tumor necrosis factor and nitric oxide, irrespective of co-stimulation with interferon-gamma, a potent priming agent for macrophage antitumoral activity. On the contrary, treatment with higher photosensitizer doses is found to reduce markedly the viability of the macrophage effector cells. Thus, these results do not lend any support to the hypothesis of direct macrophage activation by photodynamic treatment. However, macrophages are found to be activated for tumoricidal effector functions indirectly by photodynamically killed tumor cells, in a way reminiscent of phagocytosis-inducing stimuli. It is thus suggested that recognition and phagocytosis of photodynamically destroyed tumor cells constitutes the major signal for local activation of macrophages in photodynamically treated tumor tissues, which may be crucial for final, specific eradication by the immune system of tumor cells surviving photodynamic treatment.

Abstract
The new large scale synthesis of the yellow colored vitamin B6 analogue 5'-O-phosphono-pyridoxylidenerhodanine (2) (B6PR) leads to oligohydrates of its monosodium salt (4). The light-red hemiheptadecahydrate (8 1/2 hydrate) (4a) was crystallized and its three-dimensional structure determined by X-ray crystallography. Special nucleotide and protein interaction properties together with scavenging antioxidative function are combined in this simple water-soluble vitamin B6 analogues B6PR. High (mM) concentrations were untoxic to 'healthy' not affected cells and primary tissues. Complexation of ions (e.g. Ca2+, Fe2+, and Zn2+), modulation of nitric oxide synthases (NOS I-III), nitric oxide (NO) metabolism, and reactive oxygen species (ROS) was found. Special cytoprotecting, immunomodulating, stimulating and inhibiting activities were observed in vitro, not in comparison with some natural and synthetic pyridoxines. Low B6PR suppressed proliferation, high induced selective cell death of some cancer cell lines. Low B6PR protected HIV-1-infected CD4+ HUT 78 cells against HIV-1-mediated destruction (complete inhibition of HIV-1-induced syncytia formation and cell death) and reduced p24 level. Autoreactive S100beta-specific T cells of Lewis rat, a model of multiple sclerosis, could be influenced. Oxidative damage and age, acquired and inherited disease related pathophysiological disorders can be treated by this new cytopathology-selective versatile acting B6PR.

Abstract
In vitro photodynamic treatment of YAC-1 murine T-lymphoma cells with the hematoporphyrin derivative Photosan 3 and red light resulted in dose-dependent phototoxicity. Photodynamic pretreatment, however, did not render these cells more susceptible to macrophage-mediated tumor cytotoxicity or the cytotoxic effects of macrophage-derived antitumor mediators like tumor necrosis factor alpha (TNF-alpha) or interferon beta (IFN-beta). Independent of the degree of photosensitization used, the cytotoxicity values obtained with macrophages or the different mediators were shifted by the respective values for phototoxicity, suggesting these effects to be additive and thus not interdependent. These data show that while higher overall tumor cytotoxicity can be achieved by a combination of photodynamic treatment and macrophage-mediated tumor destruction, this apparently is not a result of enhanced sensitivity of photodynamically treated tumor cells to macrophage antitumor mechanisms in general.

Abstract
Arginase is induced in bone marrow-derived macrophages by agents that increase the intracellular concentrations of cAMP (Br-cAMP, prostaglandin E2) and, in their presence, the LPS induced NO synthesis is down regulated. Moreover, interleukin 10 which induces arginase in macrophages is able to increase the cAMP-dependent protein kinase A activity. In contrast, suppressors of NOS synthesis like protein kinase C inhibitors and calmodulin antagonists (W7), or NO activators (A23187) have no effect on the induction of arginase by LPS. These results strongly suggest that PKA is involved in the induction of arginase and supports the hypothesis that there is a reciprocal regulation of these two enzymes that drives the macrophages towards opposite functional states.
