Disynaptic inhibition shapes tuning of OFF-motion detectors in Drosophila

Amalia Braun, Alexander Borst, Matthias Meier · FENS Forum 2024

The circuitry underlying the detection of visual motion in Drosophila melanogaster is one of the best studied networks in neuroscience. Lately, electron microscopy reconstructions, algorithmic models, and functional studies have proposed a common motif for the cellular circuitry of an elementary motion detector based on both supralinear enhancement for preferred direction and sublinear suppression for null-direction motion. In T5 cells, however, all columnar input neurons (Tm1, Tm2, Tm4, and Tm9) are excitatory. So, how is null-direction suppression realized there? Using two-photon calcium ima

GABA Rdl receptors as targets for novel negative allosteric modulators with pore-blocking potential

Carlos F. Burgos, Monserrat Castro, Santiago Quintana, Pamela Godoy, Gonzalo Yévenes, Gustavo Moraga-Cid, Camila Millar · FENS Forum 2024

GABA type A receptors (GABAARs) are ligand-gated pentameric ion channels found throughout vertebrate and invertebrate nervous systems. Although their structure and function are highly conserved, they can be selectively modulated. Among insect GABA receptors, the Rdl variant has received significant attention, and recent studies have shown its ability to form functional channels with LCCH3 subunits. Mutations like A302S on GABA Rdl of Drosophila confer resistance to various insecticides. Thus, the search for novel compounds able to avoid this resistance mechanism becomes urgent. Due to a lack o
