Evolving Insights into Prickle2 in Neurodevelopment and Neurological Disorders

Area of Science:

• Neuroscience
• Developmental Biology
• Molecular Biology

Background:

• Neural circuit development is a complex process vital for nervous system function.
• Prickle2 protein, encoded by planar cell polarity (PCP) genes, is integral to the Wnt/PCP pathway.
• Prickle2 plays critical roles in neuronal development, including axon and dendrite formation.

Purpose of the Study:

• To systematically review Prickle2's role in neurodevelopment and neural circuit formation.
• To summarize upstream and downstream signaling pathways and regulatory interactions of Prickle2.
• To explore the association between Prickle2 dysregulation and neurological disorders.

Main Methods:

• Literature review of studies on Prickle2 function in neurodevelopment.
• Analysis of Prickle2's involvement in axonogenesis, dendritogenesis, synaptogenesis, and vesicle transport.
• Examination of Prickle2 expression patterns and its link to neurological diseases.

Main Results:

• Prickle2 is crucial for neuronal axon initial segment development, elongation, and regeneration.
• Prickle2 is vital for dendrite formation, synapse development, and intracellular vesicle transport.
• Prickle2 dysregulation is implicated in congenital neural tube defects, Alzheimer's disease, epilepsy, and autism spectrum disorders.

Conclusions:

• Prickle2 is a key regulator of neural circuit formation with diverse functions.
• Understanding Prickle2's mechanisms offers insights into neurodevelopmental processes.
• Prickle2's role in neurological disorders highlights its therapeutic potential.
