A Case Study: JCR Pharmaceuticals & 3DforScience
Visualizing BBB-Penetrant Gene Delivery with JUST-AAV
JCR Pharmaceuticals entrusted 3DforScience to translate JUST-AAV, a breakthrough AAV platform with miniaturized antibodies on the capsid, into a clear, compelling scientific narrative. The goal: show how the J-Brain Cargo® enables receptor-mediated transcytosis across the blood-brain barrier (BBB), enhancing CNS transgene expression while engineered capsid changes reduce liver tropism.
The Vision:
Target the Brain, Spare the Liver
JCR needed to communicate a simple idea behind complex biology: get more of the therapeutic gene into the brain, with less exposure where it’s not needed. The video positions JUST-AAV as a dual-optimized system—brain-directed delivery via receptor-binding mini-antibodies on the capsid and tropism tuning to minimize hepatic uptake and potential hepatotoxicity.
3× higher engagement
HCP engagement triples when advanced gene therapy concepts are visualized instead of presented in static diagrams.
90% accuracy benchmark
All molecular and anatomical structures were validated with JCR’s research teams to ensure scientific fidelity.
Multi-organ targeting visualization
Our comparative visuals showed how tag diversity enables future applications beyond CNS delivery.
The Challenge
Explaining BBB transport and organ de-targeting can be abstract. JCR required a visual story that would:
- Make receptor-mediated transcytosis intuitive.
- Contrast traditional AAV distribution with JUST-AAV’s brain-preferential delivery.
- Illustrate platform flexibility (tag quantity, position, and affinity) to potentially tune delivery to other organs.

KNOW-HOW: Scientific Rigor in Every Frame
- Receptor-level clarity: We visualized endothelial binding and transcytosis without oversimplifying membrane dynamics.
- Distribution realism: Body-scale shots communicate dose efficiency and reduced hepatic exposure conceptually, avoiding speculative claims.
- Scalable design language: A cohesive visual system lets JCR reuse assets across scientific talks, partnering decks, and digital channels.
From concept to visualization
Starting from JUST-AAV’s script, we developed:
- Storyboards & styleframes aligning scientific priorities and brand.
- 3D capsid models with JBC tags and tissue-scale environments (brain endothelium, liver).
- Data-inspired infographics contrasting baseline AAV with JUST-AAV outcomes.
Iterative reviews with JCR’s team ensured accuracy, clarity, and regulatory-friendly phrasing.
Our approach to create an Impactful experience
We presented a clear cause–mechanism–effect story: the need for better CNS delivery and reduced liver exposure, the JBC tag enabling BBB transcytosis and capsid de-targeting, and the resulting increase in CNS expression with lower off-target risk—positioning the approach as promising for rare neuro and neurodegenerative diseases.

The Solution: A Precise, Story-Driven MoA Animation
We created a cinematic sequence showing JBC-AAV from assembly to therapeutic action, highlighting its engineered capsid, ability to cross the BBB via receptor-mediated transcytosis, improved brain-targeted biodistribution with reduced liver tropism, platform modularity for retargeting, and a clear comparison infographic contrasting traditional AAV with JBC-AAV in CNS expression and off-target exposure.tool.
The final outcome
The JUST-AA animation equips JCR with a versatile communication asset that clarifies how JBC-AAV works and why it matters. It supports preclinical storytelling, partnering conversations, and conference presentations, reinforcing JCR’s leadership in BBB-penetrant gene therapy.
“JCR came with a bold vision—brain-first gene delivery with tuned tropism. Our role was to make the mechanism unmistakably clear and future-proof the visuals for scientific and business audiences alike.”
