The self-administration of cocaine could be linked to a heightened release of ATP and adenosine from astrocytes located in the nucleus accumbens shell. The A1R protomer within a putative A1R-A2AR-D2R complex's activation can possibly alter the release of glutamate at the presynaptic glutamate synapse. Our experimental hypothesis suggested that changes in presynaptic glutamate release and postjunctional heteroreceptor complex signaling, where D2R is a key player, would not alter the firing of GABA anti-reward neurons, thus preventing any reduction in cocaine self-administration in this investigation.
For therapeutic correction of pathogenic single nucleotide variants (SNVs) in the human transcriptome, RNA editing is attractive because it avoids permanent off-target edits in the genome and enables innovative delivery approaches. Human post-transcriptional RNA editing is predominantly accomplished by ADAR enzymes; their capacity to deaminate adenosine to inosine within double-stranded RNA (dsRNA) is employed to modify pathogenic single-nucleotide variants (SNVs) in the human genome at the transcriptional level. So far, the most successful methods for achieving targeted RNA editing have been based on delivering the catalytically active ADAR deaminase domain (ADARDD), fused to an RNA-binding protein, through external means. BDA-366 While the use of an ADAR-recruiting guide RNA enables the precise targeting of endogenous ADARs to a particular location, thereby maximizing packaging space, minimizing the immune response against introduced proteins, and reducing potential off-target effects across the transcriptome, its effectiveness is compromised by a low editing efficiency. By employing newly developed circular ADAR-recruiting guide RNAs and enhanced ADAR-recruiting antisense oligonucleotides, endogenous ADAR-mediated RNA editing is now demonstrating significant target editing efficacy within laboratory and biological settings. The efficiency of target editing, mirroring RNA editing by exogenous ADAR, was exhibited in both wild-type and disease mouse models, and in wild-type non-human primates (NHPs), from immediately post-application to six weeks post-treatment. The encouraging results of RNA editing with endogenous ADAR raise the possibility of a new and attractive treatment option for inherited retinal diseases (IRDs). While existing gene replacement therapy shows promise, a significant unmet need persists for genes that are too large to be packaged within adeno-associated viruses (AAVs) or genes expressed in multiple retinal forms. This paper reviews recent progress in RNA editing by endogenous ADAR enzymes, with a focus on its clinical translation to IRD treatments.
Neonatal maternal separation is a widely implemented technique in rodent research, designed to construct an early-life stress model. Pups, in this method, are removed from their mothers for several hours each day throughout the first two weeks of their lives, a practice that triggers detrimental early-life consequences. Maternal separation is a recognized factor in affecting the behavior and psychological health of adolescent offspring, often leading to manifestations of anxiety and depression. Although, environmental factors associated with maternal separation may change, for instance, the presence of other creatures or by moving the pups to a different mother. We sought to understand the divergent effects of maternal separation on adolescent mice, using the following experimental groups: (1) the iMS group, where pups were isolated in a room devoid of other adult mice in an adjacent cage; (2) the eDam group, wherein pups' dams were randomly reassigned; (3) the OF group, which included pups moved to a separate cage with bedding that contained maternal odors; and (4) the MS group, wherein pups were shifted to another vivarium. During the period from postnatal day 2 to 20, pups were daily separated from their mothers for 4 hours and subjected to diverse environments (MS, iMS, eDam, and OF). Alternatively, the control (CON) group remained undisturbed. The behavioral assessment of adolescent offspring included evaluations of locomotion, anxiety, recognition, learning, and memory. The results indicated that, across all groups, impaired recognition memory, motor coordination, and motor skill learning resulted from neonatal maternal separation. CD47-mediated endocytosis The iMS group's anxiety-like behavior was apparent in the elevated plus maze test, and this was coupled with an enhancement of fear memory extinction in the auditory fear conditioning test. Partial recovery of short-term working memory in the Y-maze test was observed in both the OF and eDam groups, but their exploratory behaviors were conversely manifested. The OF group spent a greater proportion of time positioned centrally, in contrast to the significantly shorter time spent in the center by the eDam group. The offspring of mothers experiencing separation exhibit behavioral changes in response to differing environmental stimuli during adolescence, potentially accounting for the range of behavioral phenotypes seen across various models of early-life stress.
