Organization And Development Of Cholinergic Input To The Mouse Visual Thalamus., Guela Sokhadze
Electronic Theses and Dissertations
Cholinergic signaling plays a vital role in modulating the flow of sensory information through thalamic circuits in a state-dependent manner. In the dorsal lateral geniculate nucleus (dLGN), the thalamic visual relay, release of acetylcholine (ACh) contributes to enhanced thalamocortical transfer of retinal signal during behavioral states of arousal, wakefulness, and sleep/wake transitions. Moreover, ACh modulates activity of the thalamic reticular nucleus (TRN), a structure which provides inhibitory input to dLGN. While several cholinergic nuclei have been shown to innervate dLGN and TRN, it is unclear how projections from each area are organized. Furthermore, little is known of how or when …
Functional And Structural Impact Of The Loss Of The Leucine-Rich Repeat Protein Lrit1 In The Mouse Retina., Catherine Ann Cobb
Functional And Structural Impact Of The Loss Of The Leucine-Rich Repeat Protein Lrit1 In The Mouse Retina., Catherine Ann Cobb
Electronic Theses and Dissertations
Mutations in genes encoding the leucine-rich repeat (LRR) proteins nyctalopin and LRIT3 lead to complete congenital stationary night blindness because they are critical to depolarizing bipolar cell function in the retina. LRIT3 has two closely related family members, LRIT1 and LRIT2. In silico analyses of publicly available RNA-Seq data showed that Lrit1 was highly expressed in the retina. Here I describe the expression pattern and impact of loss of LRIT1 on retinal function. To enable these studies, we used CRISPR/Cas9 technology to create an Lrit1-/- mouse line. Retinal morphology and morphometry analyses showed no gross changes in retinal structure …
