These authors discarded a possible toxic effect of AAP in those tissues due to the low activity of the cytochrome P-450 system, as determined by the lower covalent binding in the brain and kidneys when compared to the liver, but they did not study the effect of AAP on renal or brain cells viability directly [6].
However, the actions of Cdt venom on cell viability of brain slices is likely to be devoid to the presence of crotoxin and crotamine that ultimately account for the increase of excitatory neurotransmitters [ 22], resulting in excitotoxicity [ 38].
Quantitative and qualitative aspects of DMPK biology via mitochondrial involvement could thus contribute to typical features of DM1 disease manifestation, including defective Ca2+ ion homeostasis, insulin resistance and loss of cell viability in muscle, brain and other organs [7].
HBE (100 μ g/mL) and quercetin (10 μ g/mL) also increased cell viability in mice brain slices.
Also, the effectiveness of HBE and quercetin was validated, to counteract the deleterious effects induced by C. d. terrificus venom, on cell viability of mouse brain slices.
Analyses of neuropeptides that are endogenous factors in brain tissue revealed that PACAP [19] increased cell viability (Fig. 5D).
Although neither treatment affected growth or viability, each elicited alterations in indices of brain cell differentiation and cholinergic innervation in the immediate posttreatment period (PN15), persisting into adulthood (PN60).
We investigated cytosolic PrP biogenesis and effect on cell viability in primary neuronal cultures from different mouse brain regions.
At mouse brain slices, Cdt venom (1, 5, and 10 μ g/mL) decreased cell viability.
The observed decrease in cell viability induced by IFNγ may negatively influence the survival and recruitment of NPCs after brain injury or in different diseases.
