Girk2 And Gababr1 Downregulate In Response To Ttx As Girk2, Gababr1, And Gababr2 Are Not Affected By Bc Treatment, Staci E. Hammer, Amanda Weiss, Hee Jung Chung

Homeostatic plasticity is the response neurons undergo to regulate changes in excitability levels and bring the cells back to homeostasis. Research on homeostatic plasticity at the molecular level can lead to improved treatments for neurological diseases such as epilepsy, Alzheimer's, and schizophrenia. The research featured in this poster looks at the response of GIRK (G protein-gated inwardly rectifying potassium) channels and GABAb (gamma-amniobutyric acid) receptors to neurotoxins, tetrodotoxin (TTX) or bicuculline (BC).

Prolonged activity blockade of 48 hour TTX treatment significantly reduced GABABR1 and GIRK2 expression. This supports the idea that because these two proteins inhibit action potentials, there will …

Thick Slice Clarity For Localization Of Novel Neuroactive Target Gene Products, Eva C. Ping, Michael C. Saul, Lisa Stubbs

This poster describes the Thick Slice CLARITY technique, an alternative to the whole tissue or whole body clarity technique. The CLARITY technique is a tissue clearing method allowing for both structural and molecular analysis of a tissue sample, but the method applied to whole tissue or body is very expensive and time consuming. Thick Slice CLARITY applies the same principles but to a 200 micrometer slice of brain tissue. This method, used in conjunction wit standard fluorescent staining methods and imaging via confocal microscopy, has allowed for the colocalization of GPR3 with neurons in the mouse striatum.
