Fast Regulation of GABAAR Diffusion Dynamics by Nogo-A Signaling.

2019

Summary: Precisely controlling the excitatory and inhibitory balance is crucial for the stability and information-processing ability of neuronal networks. However, the molecular mechanisms maintaining this balance during ongoing sensory experiences are largely unclear. We show that Nogo-A signaling reciprocally regulates excitatory and inhibitory transmission. Loss of function for Nogo-A signaling through S1PR2 rapidly increases GABAAR diffusion, thereby decreasing their number at synaptic sites and the amplitude of GABAergic mIPSCs at CA3 hippocampal neurons. This increase in GABAAR diffusion rate is correlated with an increase in Ca2+ influx and requires the calcineurin-mediated dephospho…

Glicerīna transportsistēmas un Hog1 loma raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī

2015

Šī darba mērķis bija izpētīt glicerīna transportsistēmu un Hog1p iespējamo lomu raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī. Lai sasniegtu šo mērķi, izmantoja raugu Saccharomyces cerevisiae BY4741 un tā izogēnos celmus, kuriem trūka viens vai vairāki gēni, kuri ir atbildīgi par glicerīna transportiera Stl1p, glicerīna eksporta kanāla Fps1p un regulatorās Hog1p MAP kināzes ekspresiju raugu šūnās. Darbam bija izvirzīti sekojošie uzdevumi: izpētīt S. cerevisiae BY4741 spējas pāriet anhidrobiozes stāvoklī; novērtēt glicerīna transportsistēmu Stl1p un Fps1p, ka arī Hog1p ietekmi uz raugu šūnu rezistenci pret dehidratāciju; izpētīt raugu spējas pārdzīvot osmotisko stresu un šīs ied…
