The allele Mx regulates the extent to which interferon alpha/beta inhibits the growth of influenza viruses in mouse cells such as peritoneal macrophages. The time course of induction of the antiviral state against an influenza A virus is comparable in macrophages with and without Mx and is similar to that found with vesicular stomatitis virus. In contrast, the decay of the antiviral state again...

Though the general appearance and the cellular composition of the pancreatic islets of the Mongolian gerbil (Meriones unguiculatus) conformed to those of most other rodent species, some peculiar ultrastructural details were found. Thus there were diversiform, mainly vesicular particles with varying electron opacity in these islets. The vesicular particles showed a clear association to cilia whi...

Un cuadro de meningitis aséptica, en el contexto un paciente inmunosuprimido con diagnóstico infección por Virus Inmunodeficiencia Humana (VIH), debe llevar a pensar múltiples diagnósticos diferenciales. Entre estos, se incluye virus varicela zóster (VVZ) como uno los principales agentes causales líquido cefalorraquídeo claro. Su reactivación da lugar manifestaciones neurológicas potencialmente...

Vesicular lipoproteins (e.g., lipoprotein-X) are found in plasma in cholestasis or following infusion of Intralipid or phospholipid. To investigate the metabolism of vesicular lipoproteins, we isolated them from the plasma of subjects with cholestasis or following chronic or single Intralipid infusion. Cholestasis and chronic Intralipid therapy were found to be associated with elevated plasma c...

Vesicular neurotransmitter transporters package transmitter into the lumen of synaptic vesicles for quantal release. However, the number of transporters that localize to each vesicle is not known. In this issue of Neuron, a study by Daniels et al. using the Drosophila neuromuscular junction and mutations of the vesicular glutamate transporter suggests that one transporter may suffice to fill ea...

Simultaneous measurements of IVIEC and SCA by two nanotip electrodes allows direct dynamic comparison between vesicular transmitter content release to shed light on stimulation-induced plasticity.

The ATP requirement during RNA transcription by the RNA-dependent RNA polymerase associated with purified vesicular stomatitis virus was studied during chain initiation and chain elongation steps. Initiation of transcription in vitro has an apparent Km for ATP of approximately 500 micron, whereas the apparent Km for ATP during chain elongation is almost identical with those for the other three ...

Lupi et al. present, on p. 80–81, an interesting case report of dyshidrosiform palmo-plantar pemphigoid. They describe a 20-year-old man who had had itchy vesicles on his palms and soles for 1 year. Histologically, a subepi-dermal vesicle was seen, and direct immunofluorescence showed continuous linear deposition of IgG and C 3 at the dermal-epidermal junction. An enzyme-linked immuno-sorbent a...

Introducción. La neoplasia papilar intracolecística se caracteriza por el crecimiento exofítico del epitelio de la vesícula biliar hacia su interior. Casos clínicos. Presentamos dos casos clínicos con masa vesicular a quienes les realiza colecistectomía, dado riesgo que esos hallazgos sean pólipos vesiculares malignos. anatomía patológica certifica corresponden una intracolecística. Discusión. ...
