AAV2-retro
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Using the 2020 review on intersectional AAV targeting as the anchor, the strongest enrichment leads are the primary method papers that the review explicitly builds on: the engineered retrograde capsid AAV2-retro (Tervo et al., 2016).
Usefulness & Problems
No literature-backed usefulness or problem-fit explainer has been materialized for this record yet.
Published Workflows
Objective: Systematically identify and characterize engineered ocular and neurotropic AAV capsids tested in non-human primates from the published literature.
Why it works: The review describes a structured search over PubMed abstracts using specific entity and context terms, followed by refinement to a smaller relevant set, allowing a large literature to be narrowed into a tractable translational summary.

Stages
- 1.PubMed abstract query and broad retrieval(in_silico_filter)
This stage captures a broad initial literature set using structured query terms relevant to capsids, route, and biological context.
Selection: Specific mentions of AAVs, administration routes, and organ/tissue/species in PubMed abstracts
- 2.Optimized refinement to relevant unique abstracts(hit_picking)
This stage narrows a very large initial search result into a tractable set of abstracts suitable for systematic review and translational synthesis.
Selection: Relevance and uniqueness after an optimized refinement process
- 3.Route-based characterization and synthesis of engineered capsids(functional_characterization)
Organizing findings by administration route supports translational interpretation of where different engineered capsids may be most useful.
Selection: Summarization of novel capsids by administration route: systemic CNS targeting, direct CNS injection, and ocular administration
Steps
- 1.Query PubMed abstracts for AAV, route, and organ or species termsliterature-mining method
Generate a broad candidate literature set relevant to engineered ocular and neurotropic AAV capsids tested in non-human primates.
A broad search is needed first to capture the rapidly growing literature before narrowing to a curated evidence set.
- 2.Refine initial hits to relevant and unique abstracts
Reduce the broad search output to a manageable and nonredundant set for review synthesis.
Refinement follows broad retrieval so that downstream characterization is performed on a focused evidence set rather than on thousands of raw hits.
- 3.Summarize retained capsids by administration route and translational attributescharacterization aid
Organize the final evidence set into route-specific categories and summarize translationally relevant capsid properties.
Route-based synthesis is performed after refinement so that interpretation focuses on the most relevant and unique abstracts.
Objective: Target AAV-mediated gene expression to discrete neuron populations defined by axonal connectivity in order to dissect neural circuits.
Why it works: The review states that these approaches use axonal connectivity logic to restrict AAV-mediated expression to discrete neuron populations, allowing circuit-specific labeling and manipulation.
