Abstract:
Rationale Chronic obstructive pulmonary disease (COPD) is a progressive lung condition with extrapulmonary manifestations- cardiovascular diseases (CVD), impaired physical function, activity and increased frailty. Integrating measures of function into community assessments is hindered by the space and time required. The association of function, activity and CVD has not been extensively investigated in COPD. Objectives Explore the potential utility of Time Up and Go (TUG) as a measure of physical function in COPD Assess association of non-invasive measures of haemodynamics to physical function and self-reported activity Explore ambulatory haemodynamics in COPD and controls Methods Subjects with COPD (n=119) and controls (n=58) were recruited. Ethical and governance approvals were obtained. A medical history including falls, spirometry, peripheral and central haemodynamics, self-reported physical activity questionnaires and functional assessments (TUG and six-minute walk distance (6MWD)) were obtained from all subjects. Ambulatory 24-hour haemodynamics including aortic pulse wave velocity (aPWV) and blood pressure were measured in patients (n=20) and controls (n=19). Results TUG mean(SD) was increased in patients 11.9(3.7)s compared to controls 9.5(1.8)s, p < 0.001. In patients, fallers had longer TUG than non-fallers (p=0.02) and a cut-off time of 12s had the highest sensitivity and specificity to detect fallers and non-fallers. Aortic stiffness was not associated to physical function or physical activity, p > 0.05. In the pilot study, significant nocturnal dip in aPWV was seen in controls, p < 0.01, but not in patients, p=0.07. Conclusion TUG could be a useful measure of function and possibly be incorporated into COPD assessment, particularly where time and space are limited. Finally, ambulatory haemodynamic machine, the Mobil-O-Graph, is feasible and offers opportunity to assess 24-hour haemodynamics profile including aPWV as opposed to a one-off measurement.

Abstract:
Die vorsätzliche Freisetzung von Variola Virus (VARV) und schwere Erkrankungen des Menschen durch zoonotische Affen- (MPXV) und Kuh- (CPXV) pocken Viren stellen nach wie vor eine Bedrohung für die Bevölkerung dar. Klassische Pockenimpfstoffe bergen die Gefahr einer schweren Erkrankung. Deshalb ist die Entwicklung neuer Impfstoffe und Therapeutika von entscheidender Bedeutung. Deren Wirksamkeit und Sicherheit muss zunächst in verschiedenen Tiermodellen bewiesen werden. Existierende Makakken-Primatenmodelle leiden unter sehr artifiziellen Bedingungen der letalen Krankheitsinduktion durch VARV oder MPXV. Aus diesem Grund wurde das Calpox Virus/Krallenaffen-modell etabliert, welches auf einem CPXV aus natürlich infizierten Neuweltaffen (Marmosets) basiert. Das neue Modell hat drei wesentliche Vorteile: Die Arbeit mit Calpox Virus kann unter Sicherheitsstufe 2 durchgeführt werden und ist folglich einfacher in der Handhabung. 2. Die intranasale (i.n.) Infektion von Marmosets (Krallenaffen; Callithrix jacchus) spiegelt den natürlichen Infektionsweg von VARV wieder. Infizierte Affen entwickelten Pocken ähnliche Symptome und verstarben innerhalb von 2-3 Tagen nach Auftreten erster Symptome. Hohe Viruslasten wurden im Blut, Speichel und allen untersuchten Organen nachgewiesen. 3. Die i.n. Titration des Calpox Virus ergab eine 50 % Affen-Infektions-Dosis (MID50) von 8.3x102 pfu. Diese ist um den Faktor 10000 niedriger als in anderen Pocken-Primatenmodellen. Neun bis zehn Wochen nach einer Immunisierung mit dem Lister-Elstree Impfstoff waren alle Krallenaffen gegen eine letale Dosis des Calpox Virus (10 MID50) geschützt. Damit konnte der Nutzen des Calpox Virus/Krallenaffen-modells für die Erforschung neuer Impfstoffe gezeigt werden. Das Calpox Virus/Krallenaffen-modell überwindet wesentliche Nachteile bestehender Primatenmodelle und ist somit ein geeignetes Model für die Evaluierung von neuen Impfstoffen, Impfstrategien und antiviralen Therapien.
The intentional re-introduction of Variola virus (VARV), the agents of smallpox, into the human population remains of concern today. Moreover, zoonotic infections with Cowpox (CPXV) and Monkeypox virus (MPXV) cause severe diseases in humans. Smallpox vaccines presently available can have severe adverse effects that are no longer acceptable. The efficacy and safety of new vaccines and antivirals have to be demonstrated by different animal models. The existing primate models, using VARV and MPXV, need very high viral doses that have to be applied intravenously to induce a lethal infection in macaque monkeys. To overcome these drawbacks, the main objective of this study was to develop a primate model in which a smallpox-like disease could be induced by a CPXV virus designated calpox virus which was isolated from a lethal orthopox virus (OPV) outbreak in New World monkeys (marmosets). The new non-human primate model has three major advantages: 1. Working with calpox virus is less challenging and can be done under bio-safety-level two. 2. Mimicking the natural route of VARV infection, intranasally infected marmosets (Callithrix jacchus) reproducibly developed clinical symptoms of an OPV infection and died within two to three days after onset of the first symptoms. High viral loads of calpox virus were detected in blood, saliva and all analyzed organs. 3. Intranasal titration of the virus resulted in a 50 % monkey infectious dose (MID50) of 8.3x102 pfu, a lethal infectious dose 10,000 lower than those used in any other primate model. Moreover, we showed the aptitude of the primate model for the testing of new vaccines since nine to ten weeks after immunization with Vaccinia virus Lister-Elstree marmosets were completely protected against intranasal challenge with 10 MID50 of calpox virus. As the calpox virus/marmoset model overcomes major limitations of current primate models it is suitable to evaluate new vaccines, new vaccination strategies and antiviral therapies.

Abstract:
Kanalrhodopsine (ChRs), lichtgesteuerte Ionenkanäle, vermitteln phototaktische Reaktionen in beweglichen Algen und sind als optogenetische Werkzeuge zur Manipulation der Zellaktivität mittels Lichts weit verbreitet. Viele Kationen- und Anionen-leitende ChRs (CCRs und ACRs) wurden aus kultivierbaren Chlorophyten- und Cryptophytenarten identifiziert. Die meisten mikrobiellen Organismen kann jedoch nicht kultiviert werden, was zu einem unvollständigen Bild der ChR-Vielfalt führt. Die Metagenomik öffnet die Tür für Erkenntnisse über die Verteilung von ChRs in unkultivierten Organismen. Diese Arbeit beschreibt die biophysikalische Charakterisierung von zwei Gruppen metagenomisch identifizierter ChRs. Die MerMAIDs (Metagenomically discovered marine, anion-conducting, and intensely desensitizing ChRs) sind eine neue ChR-Familie und zeigen nahezu komplette Photostrom-Inaktivierung unter Dauerlicht. Die Photoströme lassen sich durch einen Photozyklus erklären, der zur Akkumulation eines langlebigen und nicht-leitenden Photointermediats führt. Ein konserviertes Cystein ist für dieses Phänomen entscheidend, da seine Substitution zu einer stark reduzierten Inaktivierung führt. Die Prasinophyten ChRs, die große carboxyterminale Domänen aufweisen, wurden in großen, marinen Viren identifiziert, die sie von ihren beweglichen und einzelligen Grünalgen-Wirten durch lateralen Gentransfer übernommen haben. Heterolog exprimiert, sind die viralen ChRs nur nach Ergänzung von Transportsequenzen und carboxyterminaler Kürzung funktional. Die Grünalgen- und viralen ChRs sind Anionen-leitend mit nicht-inaktivierenden Photoströmen, wenn sie in Säugetierzellen exprimiert werden, obwohl die viralen Vertreter weniger leitfähig und zytotoxisch sind. Nichtsdestotrotz repräsentiert diese ChR-Gruppe die ersten Grünalgen- und Virus-ACRs. Diese Arbeit zeigt eine breite Verteilung der ACRs unter marinen mikrobiellen Organismen und die Bedeutung der Funktionsmetagenomik bei der Entdeckung neuer ChRs.
Channelrhodopsins (ChRs) are light-gated ion channels mediating phototactic responses in motile algae and widely used as optogenetic tools to manipulate cellular activity using light. Many cation- and anion-conducting ChRs (CCRs and ACRs) have been identified from culturable chlorophyte and cryptophyte species. However, most microbial organisms cannot be cultured, resulting in an incomplete view of the diversity of ChRs. Metagenomics opens the door to gather insights on the distribution of ChRs in uncultured organisms. Here, the biophysical characterization of two groups of metagenomically identified ChRs is described. The MerMAIDs (Metagenomically discovered marine, anion-conducting, and intensely desensitizing ChRs) represent a new ChR family with near-complete photocurrent desensitization under continuous illumination. The photocurrents can be explained by a single photocycle leading to the accumulation of a long-lived and non-conducting photointermediate. A conserved cysteine is critical for this phenomenon, as its substitution results in a strongly reduced desensitization. The prasinophyte ChRs, harboring large carboxy-terminal extensions, were identified in marine giant viruses that acquired them from their motile and unicellular green algal hosts via lateral gene transfer. Expressed in cell culture, the viral ChRs are only functional upon the addition of trafficking sequences and carboxy-terminal truncation. The green algal and viral ChRs are anion-conducting and display non-desensitizing photocurrents when expressed in mammalian cells, though the viral representatives are less conductive and cytotoxic. Nonetheless, this group of ChRs represents the first green algal and viral ACRs. This thesis highlights a broad distribution of ACRs among marine microbial organisms and the importance of functional metagenomics in discovering new ChRs.
