Anti-apoptotic proteins are suggested to be important for the normal health of neurons and synapses as well as for resilience to stress. In order to determine whether stressful events may influence the expression of anti-apoptotic protein Bcl-xL in the midbrain and specifically in the midbrain serotonergic (5-HT) neurons involved in neurobehavioral(More)
The antiapoptotic protein Bcl-xL is associated with several neuroplastic processes such as formation of synapses, regulation of spontaneous and evoked synaptic responses, and release of neurotransmitters. Dependence of expression on activity of neurons is characteristic for many proteins participating in regulation of neuroplasticity. Whether such property(More)
Optogenetics, that is, the control of cell activity using photosensitive ion channels, opsins, with the light of a specific wavelength, is increasingly being used to study the activities and functions of neurons. The expression of opsins in the cell membrane, making the cell sensitive to light, is achieved by means of the viral vectors, mainly constructed(More)
The hippocampal fields of neonatal rats differ by the level of active caspase-3: dentate gyrus >CA3>CA1>CA2. In the dentate gyrus it was 70% of its maximum value in the cortex, while in CA2 it corresponded to the minimum level in the brain stem. Taking into account the role of caspase-3 in apoptosis, these differences can indicate different intensity of(More)
In the developing brain, mature brain derived neurotrophic factor (mBDNF) and its precursor (proBDNF) exhibit prosurvival and proapoptotic functions, respectively. However, it is still unknown whether mBDNF or proBDNF is a major form of neurotrophin expressed in the immature brain, as well as if the level of active caspase-3 correlates with the levels of(More)
Synthetic glucocorticoid dexamethasone decreased locomotor activity of neonatal rats 120 h after administration. Behavioral changes were associated with an increase in the content of active caspase-3 in the cerebellum. We found that expression of this apoptotic protease was similar to the control value when dexamethasone action was combined to hypoxic(More)
