Concept: Transposon driven neuronal heterogeneity.
Source: An original Report in Science (April 5, 2013).
- Background: This was already shown in yeast and mammals, now in Drosophila. Transposons account for 45% and 20% of the human and Dros genome.
- Results: Identified and characterised range of transposon activity in the olfactory memory system of mushroom bodies (MBs), especially in the neuron subtype αβ. It continues even in adult neurons.
- Implication: Neuronal mosaicism via transposons in structures associated with memory is a conserved feature of mammals/flies.
