Ca2+-independent and voltage-dependent exocytosis in mouse chromaffin cells
(Wiley Blackwell Publishing, Inc, 2020-04)
Aim: It is widely accepted that the exocytosis of synaptic and secretory vesicles is triggered by Ca2+ entry through voltage-dependent Ca2+ channels. However, there is evidence of an alternative mode of exocytosis induced ...
Stimulation of NOX2 in isolated hearts reversibly sensitizes RyR2 channels to activation by cytoplasmic calcium
(Elsevier, 2014-03)
The response of ryanodine receptor (RyR) channels to cytoplasmic free calcium concentration ([Ca2 +]) is redox sensitive. Here, we report the effects of a mild oxidative stress on cardiac RyR (RyR2) channels in Langendorff ...

Efeitos imunológicos da administração oral de ovalbumina encapsulada em lipossomas
(Universidade Federal de Minas GeraisUFMG, 2008-08-12)
Oral administration of protein antigens, such as ovalbumin, may result in induction of either tolerance or immunization. Induction of immune responses is of great interest for development of oral vaccines. On the other ...
Efeitos da deficiência de tiamina sobre aspectos cognitivos espaciais e perfil do proteoma talâmico de ratos wistar
(Universidade Federal de Minas GeraisUFMG, 2016-10-31)
Acute thiamine deficiency (TD) results in progressive neurological changes, which if left untreated, can lead to chronic brain damage and cognitive deficits, featuring a class of neurodegenerative diseases, called nutritional ...
Ischemia Enhances Activation by Ca2+ and Redox Modification of Ryanodine Receptor Channels from Rat Brain Cortex
(2008)
Cerebral ischemia stimulates Ca2+influx and thus increases neuronal intracellular free [Ca2+. Using a rat model of cerebral ischemia
without recirculation, we tested whether ischemia enhances the activation by Ca2+ of ...
Avaliação ultraestrutural dos processos de granulogênese e secreção e do perfil mitocondrial durante a diferenciação e ativação de eosinófilos
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE MORFOLOGIAPrograma de Pós-Graduação em Biologia CelularUFMG, 2019-11-29)
Eosinophil, an innate immune cell, plays an important role in both health and disease through its remarkable secretory capacity. Along their development, eosinophils pre- synthesize dozens of proteins and store in secretory ...
Perfil de expressão de pequenos RNAs provenientes de exossomos de pacientes em Primeiro Episódio Psicótico
(Universidade Federal de São Paulo, 2021-06-28)
A Esquizofrenia é uma doença psiquiátrica grave, multifatorial e poligênica. O primeiro episódio psicótico é considerado o início desta doença e é uma fase extremamente interessante para estudo, uma vez que os pacientes ...
