Easy In Vitro Synthesis of Optimised Functioning Reporter mRNA from Common eGFP Plasmid.

The extensive growth in number and importance of experiments and clinical-aimed techniques based solely or majorly on the activity of RNA strands, e.g. CRSPR/Cas9 and siRNA, has put emphasis on the necessity of standardisation of experiments with RNA.

Importance of major histocompatibility complex of class I (MHC-I) expression for astroglial reactivity and stability of neural circuits in vitro.

MHC-I molecules are involved in the antigenic presentation of cytosol-derived peptides to CD8T lymphocytes. In the nervous system, MHC-I expression is low to absent, occurring only during certain phases of development and aging or after injuries. The involvement of MHC-I in synaptic plasticity has been reported and, following lesion, astrocytes become reactive, limiting tissue damage.

Triggering of protection mechanism against Phoneutria nigriventer spider venom in the brain.

Severe accidents caused by the "armed" spider Phoneutria nigriventer cause neurotoxic manifestations in victims. In experiments with rats, P. nigriventer venom (PNV) temporarily disrupts the properties of the BBB by affecting both the transcellular and the paracellular route.

Local injection of BDNF producing mesenchymal stem cells increases neuronal survival and synaptic stability following ventral root avulsion.

The present study proposed to graft mesenchymal stem cells (MSCs), which continuously produce BDNF, into the spinal cord ventral horn, after ventral root avulsion. Neurotrophin expression was naturally achieved by culturing MSCs in an undifferentiated state for at least 10 weeks. Lewis rats were subjected to unilateral avulsion of lumbar ventral roots, receiving 3 x 10(5) cells injected through the lateral funiculus.
