Full textMikrofluorometrische Ca2+-, Na+- und pH-Messungen in Kombination mit pharmakologischen Experimenten, biochemische Messungen der Aktivitäten von Ionentransport-ATPasen sowie videomikroskopische Analysen zu transepithelialen Wasserbewegungen wurden in dieser Arbeit durchgeführt. Sie sollten Informationen über die an der Speichelbildung und -modifikation beteiligten Transportmechanismen und die Signalwege liefern, welche durch DA und/oder 5-HT aktiviert werden.
Wesentliche Ergebnisse dieser Arbeit waren:
- Messungen des intrazellulären pH (pHi) in Gangzellen zeigten, dass isolierte Ausführgänge mit Acini bei Stimulierung mit DA und 5-HT stark ansäuerten. In isolierten Ausführgängen ohne Acini verursachte nur DA eine schwache Ansäuerung. Da nur die Ausführgänge dopaminerg innerviert sind, die Acini jedoch dopaminerg und serotonerg, zeigt dieses Ergebnis, dass die DA- und/oder 5-HT-induzierte Primärspeichelbildung die Ursache für die pHi-Änderungen in den Gangzellen ist. pHi-Messungen in den Gangzellen geben also auch Hinweise auf Transportvorgänge in den Acini.
- Der Na+-K+-2Cl--Symporter und der Cl--HCO3--Antiporter, gekoppelt mit dem Na+ H+-Antiporter (NHE) waren an der NaCl-Aufnahme in die peripheren Zellen der Acini zur Bildung des NaCl-reichen Primärspeichels beteiligt. Die Aktivität dieser Transporter hing von der CO2/HCO3--Verfügbarkeit ab und war Ca2+-abhängig.
- Die starke Ansäuerung in den Gangzellen hing nicht von der Aktivität der apikalen vakuolären Protonen-ATPase (V-H+-ATPase), aber von der Aktivität der basolateralen Na+-K+-ATPase ab, die anscheinend in den Ausführgängen die Speichelmodifikation energetisiert.
- In isolierten Ausführgängen mit Acini waren die V-H+-ATPase und Na+-abhängige Transporter (u. a. NHE) an der Erholung von einer DA-induzierten oder einer NH4Cl-Vorpuls-induzierten Ansäuerung in den Gangzellen beteiligt. Bei der Regulation des pHi in unstimulierten Gangzellen spielten diese Transporter keine Rolle.
- In isolierten Ausführgängen mit Acini induzierte DA in den Gangzellen einen Anstieg der [Na+]i und, zeitlich verzögert, auch der [Ca2+]i. Der [Na+]i-Anstieg war von der Aktivität der Acini abhängig und erfolgte möglicherweise über apikale Na+-Kanäle. Der [Ca2+]i-Anstieg war graduiert und tonisch. Der DA-induzierte [Na+]i-Anstieg in den Gangzellen und deren Depolarisation führten dazu, dass der basolaterale Na+-Ca2+-Antiporter in den Ca2+-Influx-Modus umkehrte. Die daraus resultierende tonische [Ca2+]i-Erhöhung könnte an der Regulation der Na+-Rückresorption beteiligt sein.
- Zum Nachweis transepithelialer Flüssigkeitsbewegungen in isolierten Ausführgängen wurde eine videomikroskopische Methode entwickelt. Isolierte Ausführgänge ohne Acini resorbierten im unstimulierten Zustand Flüssigkeit aus dem Ausführganglumen. Möglicherweise sezernieren die Acini auch im unstimulierten Zustand mit geringerer Rate einen Primärspeichel, der in den Ausführgängen resorbiert wird. Die Resorption war ATP-abhängig. Der ATP-verbrauchende Transportmechanismus konnte nicht identifiziert werden. Weder die Na+-K+-ATPase noch die V-H+-ATPase waren an der Resorption beteiligt.
Diese Arbeit trug zur Kenntnis der komplexen Funktionsweise von Speicheldrüsen in Insekten bei und erweiterte das lückenhafte Wissen über die zellulären Wirkungen biogener Amine in Insekten. Zudem wurden in dieser Arbeit viele Parallelen zu Funktionsweisen der Speicheldrüsen in Vertebraten deutlich.
The acinar salivary glands in the cockroach Periplaneta americana are innervated by dopaminergic and serotonergic fibers and secrete a NaCl-rich primary saliva upon stimulation with the biogenic amines dopamine (DA) or serotonin (5-HT). The ducts downstream of the acini are thought to modify the primary saliva by Na+ reabsorption and K+ secretion. The electrolyte and fluid transport processes activated by DA and 5-HT as well as the second messenger pathways mediating between the biogenic amine receptors and the effector transport mechanisms are poorly understood.In this sudy, microfluorometrical Ca2+, Na+ and pH measurements were performed in combination with pharmacological experiments. Furthermore, ATPase activity assays and microscopical analyses of transepithelial fluid transport were done. The aim of this work has been the characterisation of the DA-induced transport mechanisms in the cockroach salivary glands in order to improve our understanding of the cellular actions of biogenic amines in insects.
Intracellular pH measurements in duct cells of isolated small lobes of salivary glands consiting of several acini and ducts showed a strong intracellular acidification upon DA or 5-HT stimulation. On the other hand, only a small intracellular acidification could be recognised in isolated ducts without acini. The acini are innervated by dopaminergic and serotonergic fibers, whereas the ducts are innervated only by dopaminergic fibers. Thus, this result demonstrates, that the DA- or 5-HT-induced production of primary saliva in the acini causes the intracellular pH changes in the ducts. Consequently, intracellular pH measurements in ducts are also useful to characterise transport processes in the acini.
The Na+-K+-2Cl- cotransport and/or the Cl--HCO3- exchange combined with the Na+ H+ exchange (NHE) were responsible for the NaCl uptake at the basolateral membrane in the peripheral cells of the acini during production of primary saliva. The activity of these transporters was regulated by the CO2/HCO3--availability and was Ca2+-dependent. The activity of the basolateral Na+-K+-ATPase, but not of the apical vacuolar-type proton pump (V-H+-ATPase) in the duct cells was necessary for the strong intracellular acidification in the ducts with acini. Thus, the Na+-K+-ATPase seems to energise the saliva modification in the ducts. In ducts with acini, the V-H+-ATPase and Na+-dependent transporters (e.g. NHE) were responsible for the pH-recovery after a DA- or NH4Cl-induced intracellular acidification in the duct cells. In the regulation of the intracellular resting pH these transporters played a minor role. In addition, DA induced an increase in the intracellular Na+ concentration, followed by an increase in the intracellular Ca2+ concentration in duct cells with acini, but never in duct cells without acini. The Na+ elevation was probably the result of the activity of apical Na+ channels. The DA-induced Na+ elevation and a depolarisation of the basolateral membrane of the duct cells reversed a Na+-Ca2+ exchange activity into the reverse mode causing a graded Ca2+ elevation in duct cells. The Ca2+ elevation is probably involved in the regulation of the Na+ reabsorption during saliva modification. Transepithelial fluid transport in isolated ducts was detected with a fluorescent microscopical method. Already unstimulated isolated ducts reabsorbed fluid from the duct lumen to the bath side. Perhaps unstimulated acini possess a basic secretion rate and this primary saliva is than reabsorbed in the ducts. The fluid reabsorption was ATP-dependent, but the ATP-consuming transport mechanism could not be identified. Neither the basolateral Na+-K+-ATPase, nor the apical V-H+-ATPase were involved in fluid reabsorption. This work extends our knowledge about the complex function of insect salivary glands and about the cellular action of biogenic amines in insects. Additionally, it indicates lots of similarities between the functions of salivary glands in vertebrates and invertebrates.

Full textThe transport of HIV through the fetal membranes is discussed as one possible reason for the vertical transmission of HIV from mother to child during pregnancy or labor. HIV can penetrate epithelial barriers by a receptor-mediated transport mechanism involving interaction of a lectin-like domain on the viral glycoprotein gp120 and a receptor on the epithelial surface. In this study the domain on gp120 involved in transcytosis of cell-free HIV-1 through epithelial cells was characterized in more detail. Overlapping oligopeptides of gp120 were used to inhibit transcytosis of HIV 1 through an amnion cell monolayer. Four oligopeptides significantly inhibited transcytosis of HIV 1. A synthetic oligopeptide (Env362-420) with a length of 59 amino acids representing the sequence of the four inhibiting oligopeptides significantly reduced the transport of HIV, independent of the HIV 1 subtype. Furthermore, human HIV-positive sera with antibodies reacting with the domain Env362-420 and rabbit sera raised against the oligopeptide Env362-420 also inhibited the transport of HIV-1. Antibodies directed against the transcytosis domain could be detected in sera from every stage of infection. The development of these antibodies in the early stage of infection might play a role in the outcome of the HIV disease.It has to be investigated whether HIV 1-infected women who developed these antibodies show a lower rate of HIV transmission to their offspring than those without such antibodies. Env362–420 can also be used as a tool to identify the receptor involved in transcytosis on the epithelial cell surface and to develop inhibitors that could help prevent mother-to-child transmission of HIV during pregnancy or labor.
