Differential effects of trimethylamine and quinine on seizures induced by 4-aminopyridine administration in the entorhinal cortex of vigilant rats
(2010)
In vivo and in vitro evidence from animals suggesting that gap junctions (GJs) play a role in the spreading of epileptiform activity. We have examined the influence of the gap junction opener trimethylamine (TMA) and the ...
Características ultra-estruturais das células de Sertoli do morecego hematófago (Desmodus rotundus rotundus, Geoffrey, 1810).
(1993-11-01)
This paper deals with the ultrastructural study of mature vampire bat Sertoli cells and their relationships with the different stages of testicular germ cells. In vampire bat seminiferous epithelium there are different ...

Beneficial and Detrimental Remodeling of Glial Connexin and Pannexin Functions in Rodent Models of Nervous System Diseases
(Frontiers Media S.A., 2019-11)
A variety of glial cell functions are supported by connexin and pannexin proteins. These functions include the modulation of synaptic gain, the control of excitability through regulation of the ion and neurotransmitter ...
Connexin hemichannel composition determines the FGF-1-induced membrane permeability and free [Ca2+](i) responses
(AMER SOC CELL BIOLOGY, 2008)
Cell surface hemichannels (HCs) composed of different connexin (Cx) types are present in diverse cells and their possible role on FGF-1-induced cellular responses remains unknown. Here, we show that FGF-1 transiently (4-14 ...
Characterization of the cellular component of polymorphous low-grade adenocarcinoma by immunohistochemistry and electron microscopy
(Elsevier B.V., 1999-03-01)
In order to characterize the cellular component of the polymorphous low-grade adenocarcinoma (PLGA) of the salivary gland, a morphological and immunohistochemical study was carried out. Thirty cases of PLGA were studied ...
Cellular pathology induced by snake venom phospholipase A2 myotoxins and neurotoxins: common aspects of their mechanisms of action
(2008-06-20)
A large variety of snake toxins evolved from PLA2 digestive enzymes through a process of ‘accelerated evolution’. These toxins have different tissue targets, membrane receptors and mechanisms of alteration of the cell ...
