Pea Aphid Brain Neuropeptides Associated with the Circadian Clock

A multimodal dataset characterizing neuropeptides in the brain of the pea aphid (Acyrthosiphon pisum), with a focus on their expression in circadian clock neurons. The data was generated by Francesca Sara Colizzi using transcriptomic, peptidomic, and immunohistochemistry approaches. It was last updated on 2026-05-28.

Use Cases

• Mapping neuropeptide expression in insect brain neurons based on immunohistochemistry data.
• Comparing circadian clock neuron profiles across insect species based on identified neuropeptides like Pigment-Dispersing Factor and Allatotropin.
• Investigating the molecular basis of seasonal photoperiodic responses in insects based on the neuropeptide map.
• Validating transcriptomic predictions of neuropeptide sequences using peptidomic data.

Strengths

• Includes a complete set of neuropeptides characterized for the pea aphid brain.
• Combines data from multiple methodologies: transcriptomics, peptidomics, and immunohistochemistry.
• Provides the first comprehensive map of neuropeptides associated with the circadian clock in this species.
• Dataset size is 8.5 GB, suggesting substantial raw or processed data files.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is packaged in a RAR archive, which requires specific software to extract.
