Abstract
Analyzing the chemical composition of seawater to understand its influence on ecosystem functions is a long-lasting challenge due to the inherent complexity and dynamic nature of marine environments. Describing the intricate chemistry of seawater requires optimal in situ sampling. Here is presented a novel underwater hand-held solid-phase extraction device, I-SMEL (In Situ Marine moleculELogger), which aims to concentrate diluted molecules from large volumes of seawater in a delimited zone targeting keystone benthic species. Marine benthic holobionts, such as sponges, can impact the chemical composition of their surroundings possibly through the production and release of their specialized metabolites, hence termed exometabolites (EMs). I-SMEL was deployed in a sponge-dominated Mediterranean ecosystem at a 15 m depth. Untargeted MS-based metabolomics was performed on enriched EM extracts and showed (1) the chemical diversity of enriched seawater metabolites and (2) reproducible recovery and enrichment of specialized sponge EMs such as aerothionin, demethylfurospongin-4, and longamide B methyl ester. These EMs constitute the chemical identity of each targeted species: Aplysina cavernicola, Spongia officinalis, and Agelas oroides, respectively. I-SMEL concentrated sponge EMs from 10 L of water in a 10 min sampling time. The present proof of concept with I-SMEL opens new research perspectives in marine chemical ecology and sets the stage for further sustainable efforts in natural product chemistry.

Abstract
The establishment of a baseline of gases from an aquifer appears to be an essential prerequisite for monitoring and securing underground storage operations such as the storage of carbon dioxide (carbon capture and storage: CCS), methane or hydrogen. This study describes an innovative metrological technique dedicated to the in situ and continuous quantification of dissolved gases (CO2, O2, N2, CH4 and H2) in a shallow aquifer, on the site of Catenoy (Paris Basin) with a water table at a depth of 13 m. Monitoring was carried out from May 7, 2019 to November 19, 2019, before the simulation of H2 injection. Gases as vapors were collected from the aquifer through a nine-meter long, half-permeable polymer membrane positioned below a packer in a 25-meter deep well. Collected gases were analyzed simultaneously at the surface by fiber Raman (CO2, O2, N2, CH4 and H2) and infrared sensors (CO2). Gas concentrations were determined from Raman and infrared data, and then converted into dissolved concentrations using Henry's law. The dissolved gas concentrations were about constant over the 6 months period with average values of 31-40 mg L-1 (CO2), 8 mg L-1 (O2), 17 mg L-1 (N2), and 0 mg L-1 (H2, CH4) indicating a very low variability in the aquifer. This is believed to allow for rapid detection of any possible abnormal concentration variation, in particular linked to an accidental arrival of gases such as hydrogen. Such an online gas measurement system can be deployed as is on any site type of underground storage without any need for adaptation.

Abstract
This study examined experimentally the combined effect of ocean acidification and warming on the productivity of rock pool multi-specific assemblages, composed of coralline algae, fleshy algae, and grazers. Natural rock pool communities experience high environmental fluctuations. This may confer physiological advantage to rock pool communities when facing predicted acidification and warming. The effect of ocean acidification and warming have been assessed at both individual and assemblage level to examine the importance of species interactions in the response of assemblages. We hypothesized that rock pool assemblages have physiological advantage when facing predicted ocean acidification and warming. Species exhibited species-specific responses to increased temperature and pCO2. Increased temperature and pCO2 have no effect on assemblage photosynthesis, which was mostly influenced by fleshy algal primary production. The response of coralline algae to ocean acidification and warming depended on the season, which evidenced the importance of physiological adaptations to their environment in their response to climate change. We suggest that rock pool assemblages are relatively robust to changes in temperature and pCO2, in terms of primary production.

Abstract
Rapid development in Yucatan has had a dramatic impact on the environment, especially the water supply. Groundwater is the only source of water in Yucatan, since surface water is virtually absent due to the karstic nature of the soil. The ring of cenotes (RC) is a geological feature which functions as a source of water and as nodes in the underground river system that canalizes water towards the coast. Numerous productive and domestic activities take place around the RC in the absence of wastewater treatment or sewage systems. Consequently, a number of researchers have hypothesized that pollutants could migrate from the land surface to the underlying aquifer and, eventually, to the coast. Therefore, the present study investigates the relationship among sources of fecal sterols and their levels in cenotes, using the expected levels of fecal sterols obtained by a spatial analysis of the sources and a Pollution Source Index. Accordingly, expected levels are compared with the detected levels of fecal sterols in 5 areas around the RC. Regarding levels, observed during a sampling campaign carried out along the RC during September 2011 (rainy season) and May 2012 (dry season), varied from low to high concentrations of sterols (0.5-2396.42 μg g(-1)) and fecal sterols (0.3-1690.18 μg g(-1)). These concentrations showed no relationship between neighboring cenotes, where similar fecal sterol concentrations or gradients were expected. When comparing expected fecal sterols levels with the detected ones, only two of the five analyzed areas concur, suggesting that no clear relationship exists among sources and fecal sterols levels at the regional scale. Multivariate analysis showed that fecal sterols were associated with sterols and fine grain particulates during the rainy season, which suggests co-transport. During the dry season, fecal sterols associated with fine grain particulate and organic matter, which indicates a change to a deposition phenomenon. These findings indicate that defining a relationship among sources and fecal sterols levels is highly difficult and this could be the result of the absorption or migration through an intricate conduit, crack, or fracture karst system. Nevertheless, the "source-levels approach", used in this study, was consistent for the northeast edge and the middle western part of the RC. New and more extensive research should be done to assess the environmental fate of fecal sterols, especially considering the intricate karstic system and its compound retention capacity.

Abstract
The gut microbiota is increasingly recognised as a key-player in defining the health status of the gastrointestinal tract. Recently, we demonstrated that colonisation of healthy germfree mice with a conventional microbiota (conventionalisation) elicits temporal and region specific host-microbe communication responses that lead to the establishment of a microbiota-accommodating homeostatic state within 30 days. Here, the microbiota composition profiles, mucosal transcriptomes and plasma-analytes in germ-free and conventionalised C57/BL 6 J mice were assessed to decipher the features of the distinctive and pivotal events occurring four days after initiation of the conventionalisation process. The dominance of the microbial genera Helicobacter, Sphingomonas and Mucispirillum in the gut microbiota coincided with the transient mounting of proinflammatory responses in the mucosa and the transiently elevated levels of specific (inflammatory) cytokines and amines in plasma. The overrepresented microbes have previously been associated with the potential to cause disease under certain conditions, illustrating that conventionalisation proceeds through a transient state that resembles situations associated with dysbiosis. However, no overt mucosal inflammation was observed, suggesting a pivotal role of the overrepresented bacterial groups in priming and maturation of the immune system during the process of conventionalisation. These findings imply that the transiently elevated relative overgrowth of particular microbial genera functions as pivotal adjuvants to elicit the corresponding proinflammatory cascades, which precede the full maturation of the different arms of the immune system following these events and is required to achieve a microbiota-accommodating homeostasis in healthy animals.

Abstract
Improving the microbiological quality of coastal and river waters relies on the development of reliable markers that are capable of determining sources of fecal pollution. Recently, a principal component analysis (PCA) method based on six stanol compounds (i.e. 5β-cholestan-3β-ol (coprostanol), 5β-cholestan-3α-ol (epicoprostanol), 24-methyl-5α-cholestan-3β-ol (campestanol), 24-ethyl-5α-cholestan-3β-ol (sitostanol), 24-ethyl-5β-cholestan-3β-ol (24-ethylcoprostanol) and 24-ethyl-5β-cholestan-3α-ol (24-ethylepicoprostanol)) was shown to be suitable for distinguishing between porcine and bovine feces. In this study, we tested if this PCA method, using the above six stanols, could be used as a tool in "Microbial Source Tracking (MST)" methods in water from areas of intensive agriculture where diffuse fecal contamination is often marked by the co-existence of human and animal sources. In particular, well-defined and stable clusters were found in PCA score plots clustering samples of "pure" human, bovine and porcine feces along with runoff and diluted waters in which the source of contamination is known. A good consistency was also observed between the source assignments made by the 6-stanol-based PCA method and the microbial markers for river waters contaminated by fecal matter of unknown origin. More generally, the tests conducted in this study argue for the addition of the PCA method based on six stanols in the MST toolbox to help identify fecal contamination sources. The data presented in this study show that this addition would improve the determination of fecal contamination sources when the contamination levels are low to moderate.

Abstract
The microbiological quality of coastal or river waters can be affected by faecal pollution from human or animal sources. An efficient MST (Microbial Source Tracking) toolbox consisting of several host-specific markers would therefore be valuable for identifying the origin of the faecal pollution in the environment and thus for effective resource management and remediation. In this multidisciplinary study, after having tested some MST markers on faecal samples, we compared a selection of 17 parameters corresponding to chemical (steroid ratios, caffeine, and synthetic compounds), bacterial (host-specific Bacteroidales, Lactobacillus amylovorus and Bifidobacterium adolescentis) and viral (genotypes I-IV of F-specific bacteriophages, FRNAPH) markers on environmental water samples (n = 33; wastewater, runoff and river waters) with variable Escherichia coli concentrations. Eleven microbial and chemical parameters were finally chosen for our MST toolbox, based on their specificity for particular pollution sources represented by our samples and their detection in river waters impacted by human or animal pollution; these were: the human-specific chemical compounds caffeine, TCEP (tri(2-chloroethyl)phosphate) and benzophenone; the ratios of sitostanol/coprostanol and coprostanol/(coprostanol+24-ethylcopstanol); real-time PCR (Polymerase Chain Reaction) human-specific (HF183 and B. adolescentis), pig-specific (Pig-2-Bac and L. amylovorus) and ruminant-specific (Rum-2-Bac) markers; and human FRNAPH genogroup II.

Abstract
AIDS is mainly a sexually transmitted disease, and accordingly, mucosal tissues are the primary sites of natural human immunodeficiency virus type-1 (HIV-1) transmission. Mucosal immunoglobulin A (IgA) antibody specific for HIV-1 envelope gp41 subunit is one correlate of protection in individuals who are highly sexually exposed to HIV-1 but remain persistently IgG seronegative (HEPS). Understanding these peculiar IgAs at the gene and functional level is possible only with monoclonal IgAs. We have constructed a mucosal Fab IgA library from HEPS and have characterized a series of HIV-1 IgAs specific for gp41 that, in vitro, are transcytosis-blocking and infection-neutralizing. Characterization of their IgA genes shows that Fab specific for the gp41 membrane-proximal region harbors a long heavy-chain CDR3 loop (CDRH3) similar to the two broadly neutralizing IgG monoclonal antibodies, 2F5 and 4E10. Furthermore, the selected Fab IgA shows extensive somatic mutations that cluster in the CDR regions, indicating that affinity maturation due to an antigen-driven process had occurred in HEPS individuals, presumably upon multiple exposures to HIV. This analysis of HEPS monoclonal IgA gives a unique opportunity to correlate an antibody function (resistance to a pathogen in vivo) with an antibody gene. Such neutralizing monoclonal IgAs could be used in microbicide formulation.

Abstract
A relatively easy synthetic method is reported for the production of the immunoadjuvant glycopeptide, N-acetyl-muramy-L-alanyl-D-isoglutamine (MDP). Most of the details in this method were also applied to the preparation of some analogs, that were synthesized in order to study structure-activity relationships.

Abstract
We report the synthesis of nine lipophilic derivatives of N-acetyl-muramyl-L-alanyl-D-glutamic-alpha-amide (MDP) or -alpha-methyl ester in which the gamma-carboxyl function of the D-glutamyl residue is either esterified by a medium chain alcohol or substituted by an L-alanyl residue esterified by a medium or long chain alcohol. A new method is described which easily allows one to obtain derivatives of MDP, bearing a free or substituted amino-acyl or peptidyl residue on the gamma-carboxyl function.

Abstract
Cytokines are involved in regulating HIV-1 infection. They are also placental environment major components. We assessed the potential impact of HIV-1 infection and/or anti-retroviral drugs on the placental cytokine profiles that may be involved in controlling HIV-1 placental dissemination. Placental explants were obtained after elective caesarean section from anti-retroviral-treated HIV-1-infected pregnant women and from HIV-1 non-infected pregnant women. The main placental cytokines were assessed for protein secretion in the supernatants of 24-h placental culture explants and/or in uncultured placental explants for mRNA expression levels. The cytokine profiles were different between the HIV-1-infected and the non-infected groups. Higher medians of leukaemia inhibiting factor (LIF), tumour necrosis factor (TNF)-alpha and interleukin (IL)-8 secretion were found in the 24-h culture supernatant of term placenta from HIV-1-infected women. High median levels of IL-16 and regulated upon activation normal T cell expressed and secreted (RANTES) levels were found in both groups. The mRNA expression medians were lower for TNF-alpha and IL-8 and higher for stromal cell-derived factor-1 (SDF-1) in uncultured placental explants from HIV-1-infected women. In the HIV-1-infected group, but not in the non-infected group, the secretion levels of TNF-alpha and IL-8, as well as their mRNA expression levels, were highly positively correlated; furthermore, their secretion levels were correlated positively with LIF and IL-10 secretion levels. We found no correlation between the cytokine levels and the immunovirological status of the HIV-1-infected mothers or the type or duration of treatment. These results highlight the potential impact of HIV-1 and of the anti-retroviral treatments on the placental cytokines pattern, independently of their anti-viral activity.

Abstract
We aimed to set up and validate a new in vitro model of placental histocultures, for the evaluation of cytokine and chemokine profiles of the placental environment, over a long culture period. Micro-explant cultures from 6 early and 6 term placentae were set up on collagen sponge gel supports at a liquid/air interface. At various times during culture, we analyzed tissue morphology and cell death by microscopy and quantified beta-hCG production and mRNA levels for beta-hCG and insulin-like 4 (INSL4). Levels of IL-6, LIF, TNF alpha, IL-10, IFN-gamma, IL-16 and RANTES in the medium were measured by ELISA on days 1, 4 and 7 of culture. SDF-1 mRNA expression was determined by real-time PCR at the same time points. Histocultures from early and term placentae remained viable until day 10. High levels of IL-6 and LIF production, low levels of TNF alpha, IL-10 and IFN-gamma production and significant SDF-1 expression were observed. These data indicate that placental histoculture is a suitable and reliable in vitro model for studying the placental environment.

Abstract
The restriction of cell-free HIV-1 infection has been demonstrated in placental trophoblast choriocarcinoma BeWo cells. We tried to determine the level of the viral replication cycle at which this restriction occurs. BeWo cells produce infectious viruses after transfection with HIV-1 plasmids, independently of viral tropism. CCR5 and CXCR4, but not the CD4 molecule, were detected at the cell surface. We therefore derived CD4-expressing clones from transfected BeWo cells. Cell-free virus infection of these clones resulted in neither virus production nor viral sequence integration, indicating that the restriction occurs before integration of the virus. If we used luciferase reporter viruses pseudotyped with HIV-1 Env R5 and X4 for infection, no luciferase activity was detected, even in the BeWo-CD4+ clone, in contrast to what was observed in VSV-G pseudotyped virus infection. Our results show that infection of trophoblast-derived cells with cell-free virus is at least restricted at the level of entry. Thus, BeWo is an interesting human placental cell line that is resistant to HIV-1, even if CD4, CXCR4, and CCR5 are expressed.

Abstract
Mother-to-child transmission can occur in utero, mainly intrapartum and postpartum in case of breastfeeding. In utero transmission is highly restricted and results in selection of viral variant from the mother to the child. We have developed an in vitro system that mimics the interaction between viruses, infected cells present in maternal blood, and the trophoblast, the first barrier protecting the fetus. Trophoblastic BeWo cells were grown as a tight polarized monolayer in a two-chamber system. Cell-free virions applied to the apical pole neither crossed the barrier nor productively infected BeWo cells. In contrast, apical contact with human immunodeficiency virus (HIV)-infected peripheral blood mononuclear cells (PBMCs) resulted in transcytosis of infectious virus across the trophoblastic monolayer and in productive infection correlating with the fusion of HIV-infected PBMCs with trophoblasts. We showed that viral variants are selected during these two steps and that in one case of in utero transmission, the predominant maternal viral variant characterized after transcytosis was phylogenetically indistinguishable from the predominant child's virus. Hence, the first steps of transmission of HIV-1 in utero appear to involve the interaction between HIV type 1-infected cells and the trophoblastic layer, resulting in the passage of infectious HIV by transcytosis and by fusion/infection, both leading to a selection of virus quasispecies.

Abstract
Reovirus type 3 clone 9 (T3C9) induces lethal encephalitis in neonatal, but not adult mice. Whether host factors that promote the development and/or functioning of nervous and gastrointestinal tissues could modulate the pathogenesis of this enteric virus was examined. The results showed that antibody specific for interleukin-3 or nerve growth factor antiserum, but not anti-interleukin-6 or anti-tumor necrosis factor-alpha/beta increased mice survival to T3C9 and decreased viral titers in nervous tissues early after infection. These data suggest that IL-3 and NGF are involved in the pathogenesis of T3C9 infection in neonatal mice.

Abstract
Vaccinia virus encodes two protein kinases (B1 and F10) and a dual-specificity phosphatase (VH1), suggesting that phosphorylation and dephosphorylation of substrates on serine/threonine and tyrosine residues are important in regulating diverse aspects of the viral life cycle. Using a recombinant in which expression of the H1 phosphatase can be regulated experimentally (vindH1), we have previously demonstrated that repression of H1 leads to the maturation of noninfectious virions that contain several hyperphosphorylated substrates (K. Liu et al., J. Virol. 69:7823-7834). In this report, we demonstrate that among these is a 25-kDa protein that is phosphorylated on tyrosine residues in H1-deficient virions and can be dephosphorylated by recombinant H1. We demonstrate that the 25-kDa phosphoprotein represents the product of the A17 gene and that A17 is phosphorylated on serine, threonine, and tyrosine residues during infection. Detection of phosphotyrosine within A17 is abrogated when Tyr(203) (but not Tyr(3), Tyr(6), or Tyr(7)) is mutated to phenylalanine, suggesting strongly that this amino acid is the site of tyrosine phosphorylation. Phosphorylation of A17 fails to occur during nonpermissive infections performed with temperature-sensitive mutants defective in the F10 kinase. Our data suggest that this enzyme, which was initially characterized as a serine/threonine kinase, might in fact have dual specificity. This hypothesis is strengthened by the observation that Escherichia coli induced to express F10 contain multiple proteins which are recognized by antiphosphotyrosine antiserum. This study presents the first evidence for phosphotyrosine signaling during vaccinia virus infection and implicates the F10 kinase and the H1 phosphatase as the dual-specificity enzymes that direct this cycle of reversible phosphorylation.

Abstract
Reovirus Type 3 clone 9 (T3C9)-induced lethal encephalitis is age dependent. We examined the effects of T3C9 inoculated into neonatal and adult mice by intracerebral, intramuscular, or peroral routes and the effect of lipopolysaccharide (LPS) on IL-1alpha levels in the blood and the brain. In parallel, we measured mice survival to T3C9 challenge, primary replication, and growth in and spread to the brain. The results show that T3C9 infection increased IL-1alpha only in the brain of neonatal mice, whereas LPS enhanced IL-1alpha in the brain and in the blood in both neonatal and adult mice. In neonatal mice, a T3C9-induced IL-1alpha increase coincided with viral replication-induced nervous tissue injury and preceded death. Anti-IL-1alpha antibody partially protected neonatal mice against T3C9 peroral challenge, further suggesting that this cytokine is involved in the mechanisms leading to lethal encephalitis. In adult mice, T3C9 was not lethal and did not modify IL-1alpha levels although it slowly replicated in nervous tissues when inoculated directly into the brain. Together, these results suggest that differences in nervous tissue response to T3C9 replication between newborn and adult mice could account in part for the age-dependent susceptibility to T3C9-induced lethal encephalitis.

Abstract
The role of CCK-B receptor activation in memory processes has been reassessed using the three-panel runway task, under conditions which avoid the effects of CCK on satiety and reduce emotional responses. For this purpose the food reinforcement usually used was replaced by a social reinforcement. The results show that learning and memory can be assessed using this procedure. Moreover, under these experimental conditions, drugs such as scopolamine, amphetamine or kinurenic acid injected into the nucleus accumbens produced behavioral deficits. BC 264, a highly selective CCK-B agonist, peripherally administered or infused into the anterolateral part of the nucleus accumbens also impaired memory. These effects were suppressed by L-365,260 supporting the involvement of CCK-B receptors and of the nucleus accumbens in memory processes.

Abstract
The effects of the selective CCK-B agonists, BC 264 and BC 197, and the nonselective CCK agonist BDNL were investigated in the elevated plus-maze in rats. BDNL and BC 197 induced anxiogeniclike effects, in contrast to BC 264, which had no effect. The behavioral responses induced by BDNL were not significantly blocked by L-365,260, but were suppressed by CI-988, another selective CCK-B antagonist, and by high doses of L-364,718, a selective CCK-A antagonist. BC 197-induced effects were also blocked by CI-988. Competition experiments performed with [3H]pBC 264 using brain membranes of guinea pig, mouse, and rat were significantly better fitted when analyzed by a two site model than by a one site model with BC 197 but not with BC 264. Moreover, BC 264 produced anxiogeniclike effects when administered with increasing doses of L-365,260 and opposing effects with increasing doses of CI-988. Together these results give pharmacological and behavioral evidence for the existence of CCK-B receptor subtypes.

Abstract
The aim of this study was to investigate the possible interaction between neuronal cholecystokinin (CCK) and opiate dependence. Rats were made dependent to morphine and the ability of cholecystokinin-octapeptide (CCK-8) and Tyr(SO3H)-gNle-mGly-Trp-(NMe)Nle-Asp-Phe-NH2 (BC 264), a selective agonist of CCK-B receptors, to induce signs of morphine withdrawal after ICV injection was tested. Behavioral responses were compared to those occurring during the naloxone-precipitated morphine withdrawal syndrome. In contrast to naloxone, CCK-8 (0.1, 1, and 10 micrograms, ICV) did not precipitate any sign of withdrawal. BC 264 (0.1, 1, and 10 micrograms, ICV) induced a strong hyperlocomotion and wet dog shakes in morphine-dependent rats, the latter effect also observed in nondependent animals. In rats receiving acute morphine, BC 264 induced an opposite effect (i.e., blockade of morphine-induced hyperactivity). Taken together, these results suggest that CCK plays only a minor role in the expression of morphine physical dependence.

Abstract
1. The effects of selective CCKB agonists, BC 264 and BC 197 were investigated in the conditioned suppression of motility test in mice, an animal model used to select antidepressant drugs. The results showed that both CCKB agonists at doses of 3 and 30 micrograms kg-1, accentuated the suppression of motility in shocked mice and did not modify the behaviour of non-shocked mice. The effects of BC 264 were suppressed by L-365,260. 2. L-365,260 alone, at doses of 0.2 and 2 mg kg-1 decreased motor inhibition in shocked mice and had no effect in non-shocked mice. 3. The effects of L-365,260 observed in shocked mice were suppressed by naltrindole, a selective antagonist for delta-opioid receptors, suggesting the occurrence of physiological adverse interactions between CCK and opioid systems. 4. Together, these results suggest that CCKB antagonists could block centrally located CCKB receptors to produce antidepressant-like effects which could indirectly involve delta-opioid receptor stimulation.

Abstract
The effects of intracerebroventricular administration of the cholecystokinin (CCK) analogue, BDNL, and the selective CCK-B agonist, BC 264, were determined using the hot plate test in mice. BDNL (0.2 nmol and 0.5 nmol) increased the jump and the paw lick latencies. These effects were blocked by the CCK-A antagonist MK-329 (0.02 mg/kg), supporting the involvement of CCK-A receptors in CCK-induced analgesia. In contrast, the selective CCK-B agonist BC 264 produced, at one dose (2.5 nmol), a slight decrease in the lick latency that was only antagonized by the CCK-B antagonist. Naloxone, but not naltrindole, antagonized BDNL-induced analgesia. The results suggest that activation of CCK-A receptors by BDNL leads to antinociceptive responses indirectly mediated by stimulation of mu-opioid receptors by endogenous enkephalins.

Abstract
1. Much evidence in the literature supports the idea that cholecystokinin (CCK) interacts with opioids in pain mechanisms. In this work, we have investigated the supraspinal interactions between enkephalins and CCK, using the hot plate test in mice. 2. Intracerebroventricular (i.c.v.) administration of BDNL (a mixed CCKA/CCKB agonist) induced dose-dependent antinociceptive responses on both paw lick and jump responses. In contrast, using the same test, the i.c.v. injection of BC 264 (a selective CCKB agonist) induced a hyperalgesic effect, which was restricted to paw licking and occurred only at a high dose of 2.5 nmol. 3. In addition, i.c.v. administration of BDNL potentiated the antinociceptive effects of the mixed inhibitor of enkephalin degrading enzymes, RB 101 and of the mu-agonist, DAMGO, while BC 264 reduced these effects. 4. Furthermore, at a dose where it interacts selectively with delta-opioid receptors, the opioid agonist BUBU reversed the hyperalgesic responses of BC 264 (2.5 nmol) but was unable to modify the effects induced by BDNL. 5. Taken together, these results suggest the existence of regulatory mechanisms between CCK and enkephalin systems in the control of pain. These regulatory loops could enhance the antinociceptive effects of morphine allowing the opiate doses used to be reduced and thus, possibly, the side-effects to be minimized.

Abstract
When CCK-8 was injected in the rat posterior nucleus accumbens, where it is in part co-localized with dopamine, a decrease in exploration of the four hole box and the elevated plus maze was observed. In this study, a selective destruction of the dopaminergic mesoaccumbens pathway induced by local injection of 6-hydroxydopamine (6-OHDA) in the nucleus accumbens was found to suppress the CCK-8-evoked behavioral effects. Moreover, an ex vivo measurement of the dopaminergic metabolism has been performed after injection of CCK-8 in the posterior nucleus accumbens by electrochemical detection of dopamine and its metabolites extracted from punches of brain tissue. The results showed that CCK-8 decreased the turnover of dopamine in the posterior part but not in the anterior part of the nucleus accumbens or in the ventral tegmental area. Furthermore, sulpiride, a selective antagonist for D2 dopamine receptors, but not SCH 23390, a selective antagonist for D1 dopamine receptors, prevented CCK-8-induced behavioral responses. Taken together, these results suggest that CCK-8 could be involved in behavioral adaptation to situations producing change in emotional and/or motivational states through modulation of presynaptic D2 receptor functioning.

Abstract
The brain peptide cholecystokinin (CCK) has been shown to counteract the analgesic effects of morphine suggesting a physiological antagonism between opioid and CCK neural systems. This has been definitely demonstrated in this study by co-administration of the CCK-B selective antagonist L-365,260 with RB 101, a systemically active inhibitor of peptidases, which fully protects the endogenous opioids, the enkephalins, from their inactivation. The naloxone reversible analgesic effects induced by RB 101 in the mouse hot-plate and rat tail-flick tests were strongly increased by low doses of L-365,260. These results could have important clinical applications by reducing the efficient dose of RB 101, which has recently been shown to be practically devoid of morphine-like side-effects.

Abstract
Potent and selective CCK-B agonists with good bioavailability have been designed by modifying the natural CCK-8 peptide. Thus, BC 264 [Boc-Tyr(SO3H)-gNle-mGly-Trp-Me(Nle)-Asp-PheNH2] is a highly potent (0.15 nM) and selective agonist for CCK-B receptors which cross the blood brain barrier. Following i.v. injection of [3H]pBC 264 in mouse, the ligand was found in its intact form in brain tissue. Analgesic studies and in vivo binding experiments have shown that the CCKergic system could modify the release of endogenous enkephalins, whereas mu and delta opioid receptor activation modulates the release of endogenous CCK. Behavioural studies performed after local injection of CCK-8 or BC 264 into the postero-median part of the nucleus accumbens have shown the involvement of CCK-A receptors in motivation and/or emotional states of rats. In the anterior part, CCK-B receptor stimulation could be involved in attention and memory processes. BC 264 systemically administered in mice increased fear and/or "anxiety" in the black and white box test. In the elevated plus maze, BC 264 increased the emotional responses of the "anxious" rat and decreased these responses in "non anxious" animals. These results suggest that endogenous CCK could play a critical role in mood modulation through CCK-A/CCK-B receptor stimulation. Dysfunctioning of the CCK-A/CCK-B pathways could be implicated in anxiety and panic attacks.

Abstract
The two membrane precursors (pentapeptide lipids I and II) of peptidoglycan are present in Escherichia coli at cell copy numbers no higher than 700 and 2,000 respectively. Conditions were determined for an optimal accumulation of pentapeptide lipid II from UDP-MurNAc-pentapeptide in a cell-free system and for its isolation and purification. When UDP-MurNAc-tripeptide was used in the accumulation reaction, tripeptide lipid II was formed, and it was isolated and purified. Both lipids II were compared as substrates in the in vitro polymerization by transglycosylation assayed with PBP 1b or PBP 3. With PBP 1b, tripeptide lipid II was used as efficiently as pentapeptide lipid II. It should be stressed that the in vitro PBP 1b activity accounts for at best to 2 to 3% of the in vivo synthesis. With PBP 3, no polymerization was observed with either substrate. Furthermore, tripeptide lipid II was detected in D-cycloserine-treated cells, and its possible in vivo use in peptidoglycan formation is discussed. In particular, it is speculated that the transglycosylase activity of PBP 1b could be coupled with the transpeptidase activity of PBP 3, using mainly tripeptide lipid II as precursor.

Abstract
The aim of this study was to examine the behavioural effects induced by stimulation of CCK receptors in the nucleus accumbens of the rat, which contains a high density of heterogenously distributed CCK-B receptors. The drug BC264 (Boc-Tyr(SO3H)-gNle-mGly-Trp-(NMe)Nle-Asp-Phe-NH2), a highly potent and selective CCK-B agonist, injected into the postero-median or antero-median n. accumbens did not modify the spontaneous alternation and exploratory behaviour observed in a Y-maze. In contrast, when administered into the antero-lateral part of the n. accumbens, BC264 (0.3-1.0 nmol) reduced alternation to chance level, without changing the number of arm visits. This effect was suppressed by the selective CCK-B antagonist: L365,260, but not by the selective CCK-A antagonist: MK329. The physiological relevance of this effect was supported by the similar responses induced, in the same concentration range, by the CCK8-like agonist, BDNL (Boc diNle28,31CCK7). These results emphasize the functional heterogeneity of the CCK network in the n. accumbens of the rat and the participation of the peptide in the expression of alternation behaviour, through stimulation of CCK-B receptors. They also show that the recently described anxiolytic effects, induced by CCK-B antagonists, do not seem to occur at this level.

Abstract
Agonists and antagonists selective for the brain-type [cholecystokinin (CCK)-B] and the peripheral-type (CCK-A) CCK receptor were used to localize the site(s) of action at which CCK inhibits food consumption. BC 264, a highly selective CCK-B receptor agonist, did not decrease consumption of a palatable meal when administered either i.p. or into the lateral ventricles of the brain, whereas CCK decreased feeding when administered i.p. at the same doses. CCK decreased feeding when administered i.v.t. at a high dose, 5 micrograms. L-364,718, an antagonist selective for the CCK-A receptor, blocked completely the action of centrally administered CCK, whereas L-365,260, a selective CCK-B receptor antagonist, had no effect on the ability of centrally administered CCK to inhibit feeding. To estimate the quantity of i.v.t. administered CCK which reached the periphery, a tracer of radiolabeled [3H]p-CCK8 ([3H]CCK octapeptide sulfate), combined with unlabeled pCCK8 (5 micrograms) was administered i.c.t. Thirty minutes after administration, intact radiolabeled pCCK8 was extracted from the plasma and measured in the blood in nanomolar concentrations, exceeding the amounts of CCK octapeptide sulfate reported previously to be present in the plasma after a meal. Intraventricularly administered CCK thus appears to reduce feeding in the rat through a mechanism involving a CCK-A receptor subtype in the periphery.

Abstract
Administration of 3 fmol of cholecystokinin octapeptide (CCK8) into the postero-median nucleus accumbens (NAS) induced an hypoexploration measured using the four-hole box and an increase in the emotional states of rats observed in the elevated plus maze. These effects seem likely to involve CCKA receptors since they were reversed by the selective CCKA antagonist L364,718 (100 micrograms/kg, 200 micrograms/kg IP) and not observed after injection of 0.1 to 1000 fmol unsulfated cholecystokinin octapeptide (CCK8NS) in the same region. On the other hand, CCK8 or CCK8NS injected into the anterior NAS did not significantly modify these behaviors. These results support the neuroanatomical heterogeneity in the distribution of CCK and its binding sites in the NAS, but raise the question of the presence of CCKA receptors not detected in binding studies and of the behavioral effects mediated by CCKB receptor stimulation in this structure.

Abstract
The serum thymic factor (FTS) utilized in its synthetic or natural form loses its biological activity in a rosette assay after treatment with a metal ion-chelating agent, Chelex 100. This activity is restored by the addition of Zn salts and, to a lesser extent, certain other metal salts. FTS activation is secondary to the binding of the metal to the peptide. The metal-to-peptide molar ratio of 1:1 provides the best activation. These data indicate the existence of two forms of FTS. The first one lacks Zn and is biologically inactive; the second one contains Zn and is biologically active, for which we propose the name of "thymulin" (FTS-Zn). The presence of Zn in synthetic FTS was confirmed by atomic absorption spectrometry. The interaction between Zn and FTS was further suggested by microanalysis demonstrating the presence of this metal in thymic reticuloepithelial cells.

Abstract
It has been previously reported that N-acetyl-muramyl-L-alanyl-D-isoglutamine (MDP), which represents the minimal structure that can substitute for mycobacteria in Freund complete adjuvant, activated macrophages in vitro and in vivo. In the present study we show that, in contrast to MDP, the nonadjuvant MDP(DD) stereoisomer has no effect on cytostatic activity of thioglycolate-induced macrophages as measured by uptake of [3H]thymidine. However, surprisingly, after conjugation to an inert carrier, multi-poly(DL-alanyl)-poly(L-lysine), this compound activates macrophages in vitro and becomes at least as effective as MDP. It has also been shown in other studies that after conjugation MDP(DD) remained devoid of antigenicity and of adjuvant activity although such a conjugate could increase resistance to infection. It, therefore, appears that there exists no correlation between the structure required for adjuvant activity and the structure required for macrophage activation or for enhancement of nonspecific immunity.
