Non-LTR Retrotransposons

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Background:

Transcription factor (TF) overexpression is a key method for modeling human neuronal differentiation and disease.
The full spectrum of neuronal subtypes that can be generated in vitro remains largely unexplored.

Purpose of the Study:

To investigate the diversity of neuronal subtypes programmable from pluripotent stem cells.
To explore the combination of developmental signaling pathways and TF overexpression for generating varied neuronal subtypes.

Main Methods:

Modulation of developmental signaling pathways alongside TF overexpression.
Screening of 480 morphogen signaling modulations and TF induction combinations.
Multiplexed single-cell transcriptomic analysis of over 700,000 cells.

Main Results:

Identification of diverse excitatory and inhibitory human neurons.
Neuronal subtypes were patterned along the developmental axes of the neural tube.
Pre-patterning neural progenitors enhanced neuronal diversity by accessing primary tissue-relevant gene regulatory networks.

Conclusions:

Combining developmental signaling modulation with TF overexpression significantly expands programmable neuronal subtype diversity.
This strategy enables the generation of human neuronal subtypes mirroring those found in vivo.
The findings provide a framework for generating diverse human cell subtypes and studying the role of signaling in neuronal fate determination.
