Establishment and remodelling of the dendritic cell network in tissues

Conventional dendritic cells (cDCs) are leucocytes that act as sentinel cells, sensing the extracellular environment and initiating immune responses against infection and cancer. cDCs develop from a common progenitor in the bone marrow (BM) that travels via the blood in the form of a pre-cDC to seed tissues. How pre-cDCs colonise different organs, whether this is affected by infection and how BM production is matched to cDC demand in the periphery remains poorly understood. During my PhD I used a mouse model for multicolour fate mapping of cDC progenitors and found that many pre-cDCs and cDCs divide in tissues generating single cDC clones. Upon infection with influenza A virus, lung cDCs increase in number due to accelerated CCR2-dependent recruitment of pre-cDCs from the BM rather than local proliferation, diluting pre-existing clones. This recruitment generates new waves of cDCs in the lung that seem to be necessary for inducing antiviral immunity. Preliminary results using a reporter mouse for DC progenitors show that more cells localise close to BM sinusoids during infection, possibly to favour the rapid release of pre-cDCs into the blood circulation. Interestingly, cancer and vaccine adjuvants also mobilise BM cDC progenitors, demonstrating that this is probably a conserved mechanism by which the cDC network adapts to different challenges. In addition, pre-cDCs can directly sense pathogen-associated molecular patterns via toll-like receptors, which might be necessary for the progenitors to respond to infection or tissue damage. In sum, my results provide evidence for a tightly regulated cDC network that is often organised in clones. However, when a bigger arsenal of cDCs is required, the BM responds by pumping out more pre-cDCs, which is a new component of immunity to infection. More studies might reveal whether CCR2 also drive this phenomenon during cancer and the mechanism underlying pre-cDC exit from the BM

UVA photoactivation of harmol enhances its antifungal activity against the phytopathogens Penicillium digitatum and Botrytis cinerea

Phytopathogenic fungi responsible for post-harvest diseases on fruit and vegetables cause important economic losses. We have previously reported that harmol (1-methyl-9H-pyrido[3,4-b]indol-7-ol) is active against the causal agents of green and gray molds Penicillium digitatum and Botrytis cinerea, respectively. Here, antifungal activity of harmol was characterized in terms of pH dependency and conidial targets; also photodynamic effects of UVA irradiation on the antimicrobial action were evaluated. Harmol was able to inhibit the growth of both post-harvest fungal disease agents only in acidic conditions (pH 5), when it was found in its protonated form. Conidia treated with harmol exhibited membrane integrity loss, cell wall disruption, and cytoplasm disorganization. All these deleterious effects were more evident for B. cinerea in comparison to P. digitatum. When conidial suspensions were irradiated with UVA in the presence of harmol, antimicrobial activity against both pathogens was enhanced, compared to non-irradiated conditions. B. cinerea exhibited a high intracellular production of reactive oxygen species (ROS) when was incubated with harmol in irradiated and non-irradiated treatments. P. digitatum showed a significant increase in ROS accumulation only when treated with photoexcited harmol. The present work contributes to unravel the antifungal activity of harmol and its photoexcited counterpart against phytopathogenic conidia, focusing on ROS accumulation which could account for damage on different cellular targets.Fil: Olmedo, Gabriela María.

Chemical and photochemical properties of chloroharmine derivatives in aqueous solutions

Thermal and photochemical stability (ΦR), room temperature UV-vis absorption and fluorescence spectra, fluorescence quantum yields (ΦF) and lifetimes (τF), quantum yields of hydrogen peroxide (ΦH2O2) and singlet oxygen (ΦΔ) production, and triplet lifetimes (τT) have been obtained for the neutral and protonated forms of 6-chloroharmine, 8-chloroharmine and 6,8-dichloroharmine, in aqueous media. When it was possible, the effect of pH and oxygen concentration was evaluated. The nature of electronic transitions of protonated and neutral species of the three investigated chloroharmines was established using Time-Dependent Density Functional Theory (TD-DFT) calculations. The impact of all the foregoing observations on the biological role of the studied compounds is discussed.Fil: Rasse Suriani, Federico Ariel Osvaldo.

Role of the National Poliovirus Laboratory for the Program of eradication and poliomyelitis surveillance

The Spanish acute flaccid paralysis surveillance network is coordinated by the National Poliovirus Laboratory (NPL), which, since 1998, carries out polioviruses (PV) and other enteroviruses detected characterization by cell culture and molecular techniques. A total of 110,725 (70046+40679) samples were studied between 1998-2012 and enteroviruses were detected in 8% of these. Among these enteroviruses 241 PV were characterized as PV Sabin-like, except samples belong to an imported poliomyelitis case, all of which were characterised as vaccine derived PV type 2. The NPL has carried out the serotyping and the intratypic differentiation of all the isolated PV in Spain of any syndrome. It is shown that wild PV has not circulated in our country during the 15 years studied and that has led to the signing of the Act of the "eradication of poliomyelitis in Spain" by WHO in 2001, and the /"certification of the eradication of wild PV free for European countries" on 21 June 2002. Currently only 3 countries have endemic transmission of wild PV (Pakistan, Afghanistan and Nigeria). Until a complete worldwide eradication, was achieved, Spain will actively continue to participate in the maintenance of the poliomyelitis eradication infrastructure by monitoring and vaccination as well as the wild PV containment plan to avoid the spread of wild PV. El Laboratorio Nacional de Poliovirus (LNP) coordina la Red Española de Vigilancia de Parálisis Flácida Aguda desde 1998 y caracteriza los poliovirus (PV) y otros enterovirus detectados, utilizando métodos de cultivo celular y moleculares. Durante 1998-2012 se estudiaron por la Red un total de 110.725 (70.046+40.679) muestras clínicas, resultando positivas para enterovirus 8.804 (8%), entre las que 241 se caracterizaron como PV. La caracterización intratípica demostró que todos los PV eran vacunales excepto las muestras correspondientes a un caso importado de poliomielitis postvacunal y sus contactos, que fueron caracterizados como PV2 derivado de vacuna. En el LNP se ha realizado el serotipado y la caracterización intratípica de todos los PV aislados en España de cualquier síndrome. Con ello se ha demostrado que el PV salvaje no ha circulado en nuestro país durante los 15 años que recoge este trabajo y eso condujo a la firma del Acta de la “Erradicación de la Poliomielitis en España” por parte de la OMS en 2001 y a la “Certificación de la Erradicación Europea como libre de circulación de PV salvaje” el 21 de junio de 2002. En la actualidad sólo 3 países presentan transmisión endémica de PV salvaje (Pakistán, Afganistán y Nigeria) y hasta que no se haya conseguido la erradicación a nivel mundial, España debe mantener la infraestructura creada en el Plan de Erradicación de la Poliomielitis y continuar con la vigilancia e inmunización. También el Programa de Contención de los PV salvajes en los laboratorios debe seguir en activo para evitar reintroducciones accidentales.S

Molecular characterization of enterovirus detected in cerebrospinal fluid and wastewater samples in Monastir, Tunisia, 2014-2017

Background: Enteroviruses (EVs) are considered the main causative agents responsible for aseptic meningitis worldwide. This study was conducted in the Monastir region of Tunisia in order to know the prevalence of EV infections in children with meningitis symptoms. Detected EV types were compared to those identified in wastewater samples. Methods: Two hundred CSF samples collected from hospitalized patients suspected of having aseptic meningitis for an EV infection between May 2014 and May 2017 and 80 wastewater samples collected in the same time-period were analyzed. EV detection and genotyping were performed using PCR methods followed by sequencing. Phylogenetic analyses in the 3'-VP1 region were also carried-out. Results: EVs were detected in 12% (24/200) CSF and in 35% (28/80) wastewater samples. EV genotyping was reached in 50% (12/24) CSF-positive samples and in 64% (18/28) sewage. Most frequent types detected in CSF were CVB3, E-30 and E-9 (25% each). In wastewater samples, the same EVs were identified, but also other types non-detected in CSF samples, such as E-17,CVA9 and CVB1 from EV species B, and EV-A71 and CVA8 from EV-A, suggesting their likely lower pathogenicity. Phylogenetic analysis showed that within the same type, different strains circulate in Tunisia. For some of the EV types such as E-9, E-11 or CVB3, the same strains were detected in CSF and wastewater samples. Conclusions: Epidemiological studies are important for the surveillance of the EV infections and to better understand the emergence of certain types and variants.Y.

Metagenomic sequencing, molecular characterization, and Bayesian phylogenetics of imported type 2 vaccine-derived poliovirus, Spain, 2021

Introduction: In 2021, a type 2 vaccine-derived poliovirus (VDPV2) was isolated from the stool of a patient with acute flaccid paralysis (AFP) admitted to Spain from Senegal. A virological investigation was conducted to characterize and trace the origin of VDPV2. Methods: We used an unbiased metagenomic approach for the whole-genome sequencing of VDPV2 from the stool (pre-treated with chloroform) and from the poliovirus-positive supernatant. Phylogenetic analyses and molecular epidemiological analyses relying on the Bayesian Markov Chain Monte Carlo methodology were used to determine the geographical origin and estimate the date of the initiating dose of the oral poliovirus vaccine for the imported VDPV2. Results: We obtained a high percentage of viral reads per total reads mapped to the poliovirus genome (69.5% for pre-treated stool and 75.8% for isolate) with a great depth of sequencing coverage (5,931 and 11,581, respectively) and complete genome coverage (100%). The two key attenuating mutations in the Sabin 2 strain had reverted (A481G in the 5'UTR and Ile143Thr in VP1). In addition, the genome had a recombinant structure between type-2 poliovirus and an unidentified non-polio enterovirus-C (NPEV-C) strain with a crossover point in the protease-2A genomic region. VP1 phylogenetic analysis revealed that this strain is closely related to VDPV2 strains circulating in Senegal in 2021. According to Bayesian phylogenetics, the most recent common ancestor of the imported VDPV2 could date back 2.6 years (95% HPD: 1.7-3.7) in Senegal. We suggest that all VDPV2s circulating in 2020-21 in Senegal, Guinea, Gambia, and Mauritania have an ancestral origin in Senegal estimated around 2015. All 50 stool samples from healthy case contacts collected in Spain (n = 25) and Senegal (n = 25) and four wastewater samples collected in Spain were poliovirus negative. Discussion: By using a whole-genome sequencing protocol with unbiased metagenomics from the clinical sample and viral isolate with high sequence coverage, efficiency, and throughput, we confirmed the classification of VDPV as a circulating type. The close genomic linkage with strains from Senegal was consistent with their classification as imported. Given the scarce number of complete genome sequences for NPEV-C in public databases, this protocol could help expand poliovirus and NPEV-C sequencing capacity worldwide.This study was partially supported by two grants from the Instituto de Salud Carlos III [grant numbers PI18CIII/00017 and PI20CIII/00005].S

Norovirus GII.3[P12] Outbreak Associated with the Drinking Water Supply in a Rural Area in Galicia, Spain, 2021

On 30 September 2021, the city council of Muxia, Spain (population of 4,564 inhabitants), reported an unusual increase of patients with acute gastroenteritis (AGE). Because geographically widespread villages belonging to the same water supply were affected, a waterborne outbreak was suspected. Overall, 115 probable cases were ascertained during epidemiological investigations carried out by the local health authority (attack rate, 5.7%); the age range was 0 to 92 years, and 54% were female. The main symptoms were vomiting (78.1%) and diarrhea (67.5%). Primary cases peaked on 29 September and subsided on 1 October, compatible with a point-source outbreak followed by possible secondary cases until 7 October. We conducted an unmatched case-control study using phone surveys. The case-control study included 62 cases and 46 controls. Univariate analysis showed that cases had a higher exposure to tap water through direct consumption (odds ratio [OR] = 86; 95% confidence interval [CI], 18 to 409) or vegetable washing (OR = 27; 95% CI, 7 to 98). Norovirus GII was detected in two terminal points of the water supply system, and 14 cases were laboratory confirmed after detection of GII in stool samples. A unique genotype (GII.3[P12]) was identified in stool samples. On 1 October, a tap water ban was put in place and the water was purged and chlorinated. The rapid increase in the number of cases and its decline after implementing control measures suggested a waterborne point-source outbreak among the residents of Muxia sharing the same water distribution system. IMPORTANCE: Noroviruses are likely to be underrecognized in most suspected waterborne outbreaks. Therefore, effective norovirus detection and the early recognition of water as a possible source of infection are important to reduce morbidity as appropriate steps are taken to control the source. In our study, we combined epidemiological, environmental, and microbiological investigations to demonstrate that it was a waterborne outbreak caused by norovirus. Metagenomic sequencing in one norovirus-positive stool sample confirmed norovirus etiology and the absence of other potential pathogens. Detection of fecal indicator bacteria and the fact that the drinking water was not chlorinated suggest a breakdown in chlorination as the cause of the outbreak. This outbreak investigation also demonstrated the importance of timely communication to the public about the risk linked to tap water consumption.This study was partially funded through the project PI20CIII/00005.S

Impact of the implementation of a telemedicine program on patients diagnosed with asthma.

Background: Asthma is one of the most common respiratory ailments worldwide. Despite broad understanding of the illness and of the available therapeutic options for it, patients with serious asthma suffer poor monitoring of their illness in 50% of cases. Aim: To assess the impact of the implementation of a mobile application (ESTOI) to control asthma in patients diagnosed with the illness, their adherence to treatment, and their perceived quality of life. Methodology: Randomized clinical trial with 52 weeks' follow-up of patients with asthma seen in a specialized hospital for their treatment in Spain. Some 108 included patients will be divided into two groups. The intervention group will undergo more exhaustive follow-up than normal, including access to the ESTOI application, which will have various categories of attention: control of symptoms, health recommendations, current treatment and personalized action plan, PEF record, nutritional plan, and chat access with a medical team. The asthma control questionnaire ACT is the main assessment variable. Other variables to be studied include an adherence test for the use of inhalers (TAI), the number of exacerbations, maximum exhalation flow, exhaled nitric oxide test, hospital anxiety and depression scale, asthma quality-of-life questionnaire, forced spirometry parameters (FVC, FEV1, and PBD), and analytic parameters (eosinophilia and IGE). The data will be collected during outpatient visits. Trial registration: This trial has registered at ClinicalTrials.gov (Identifier: NCT06116292)

Impact of the bacterial nasopharyngeal microbiota on the severity of genus enterovirus lower respiratory tract infection in children: A case-control study

Introduction: Rhinoviruses (RV) and enteroviruses (EV) are among the main causative etiologies of lower respiratory tract infection (LRTI) in children. The clinical spectrum of RV/EV infection is wide, which could be explained by diverse environmental, pathogen-, and host-related factors. Little is known about the nasopharyngeal microbiota as a risk factor or disease modifier for RV/EV infection in pediatric patients. This study describes distinct nasopharyngeal microbiota profiles according to RV/EV LRTI status in children. Methods: Cross-sectional case-control study, conducted at Hospital Sant de Déu (Barcelona, Spain) from 2017 to 2020. Three groups of children <5 years were included: healthy controls without viral detection (Group A), mild or asymptomatic controls with RV/EV infection (Group B), and cases with severe RV/EV infection admitted to the pediatric intensive care unit (PICU) (Group C). Nasopharyngeal samples were collected from participants for viral DNA/RNA detection by multiplex-polymerase chain reaction and bacterial microbiota characterization by 16S rRNA gene sequencing. Results: A total of 104 subjects were recruited (A = 17, B = 34, C = 53). Children's nasopharyngeal microbiota composition varied according to their RV/EV infection status. Richness and diversity were decreased among children with severe infection. Nasopharyngeal microbiota profiles enriched in genus Dolosigranulum were related to respiratory health, while genus Haemophilus was specifically predominant in children with severe RV/EV LRTI. Children with mild or asymptomatic RV/EV infection showed an intermediate profile. Conclusions: These results suggest a close relationship between the nasopharyngeal microbiota and different clinical presentations of RV/EV infection.This project is supported by the Spanish National Health Institute Carlos III (Grant id.

N-methyl-β-carboline alkaloids: structure-dependent photosensitizing properties and localization in subcellular domains

N-methyl-Beta-carboline (bC) alkaloids, including normelinonine F and melinonine F, have been found in a vast range of living species playing different biological, biomedical and/or pharmacological roles. Despite this, molecular bases of the mechanisms through which these alkaloids would exert their effect still remain unknown. Fundamental aspects including the photosensitizing properties and intracellular internalization of a selected group of N-methyl-bC alkaloids were investigated herein. Data reveal that methylation of the bC main ring enhances its photosensitizing properties either by increasing its binding affinity with DNA as biomolecular target and/or by increasing its oxidation potential, in a structure dependent manner. As a general rule, N(9)-substituted bCs showed the highest photosensitizing efficiency. With the exception of 2-methyl-harminium, all the N-methyl-bCs investigated herein induce a similar DNA photodamage profile, dominated largely by oxidized purines. This fact represents a distinctive behavior when comparing with N-unsubstituted-bCs. On the other hand, although all the investigated compounds might accumulate mainly into the mitochondria of HeLa cells, methylation provides a distinctive dynamic pattern for mitochondrial uptake. While rapid (passive) diffusion is most probably reponsible for the prompt uptake/release of neutral bCs, an active transport appears to mediate the (reatively slow) uptake of the quaternary cationic bCs. This might be a consequence of a distinctive subcellular localization (mitochondrial membrane and/or matrix) or interaction with intracellular components. Biomedical and biotechnological implications are also discussed herein.Fil: Denofrio, Maria Paula. Consejo Nacional de Investigaciones Científicas y Técnicas.
