AbbVie's neuroscience portfolio has significant relevance to Multiple System Atrophy, an α-synucleinopathy with prominent autonomic dysfunction:
- ABBV-954 (α-synuclein inhibitor): Direct relevance to MSA pathogenesis; oligodendrocyte α-syn pathology is a hallmark of MSA
- Autonomic dysfunction expertise: AbbVie's research on autonomic dysfunction in PD (Duodopa, orthostatic hypotension) directly translates to MSA, where autonomic failure is a core feature
- Gene therapy (ABBV-951): AADC gene therapy may have potential for MSA-P variant with severe dopaminergic deficits
- TREM2 partnerships: Neuroinflammation research relevant to MSA pathology
AbbVie's Parkinson's disease portfolio addresses several autonomic dysfunction manifestations common in PD:
Duodopa/Duopa (Levodopa-Carbidopa Intestinal Gel)
Duodopa provides significant benefit for autonomic symptoms in advanced PD:
- GI Dysfunction: Continuous intestinal delivery bypasses gastric emptying issues, addressing gastroparesis and constipation that affect up to 80% of PD patients
- Improved Medication Timing: Stable plasma levodopa levels reduce fluctuations that can exacerbate autonomic symptoms
- OFF-time Reduction: Reducing OFF episodes can decrease catecholamine surges and associated blood pressure fluctuations
Blood Pressure Regulation
AbbVie's neuroscience programs explore mechanisms relevant to orthostatic hypotension:
- Research into alpha-synuclein propagation and its effects on autonomic nuclei including the dorsal motor nucleus of the vagus and locus coeruleus
- TREM2 partnerships may provide insights into neuroinflammation effects on autonomic regulation

AbbVie has developed the BRAIN (Blood-brain barrier "Receptor" ABC for Intractable CNS) platform, a proprietary technology for delivering large molecule therapeutics across the blood-brain barrier. This platform represents AbbVie's strategic investment in addressing the long-standing challenge of CNS drug delivery.
The BRAIN platform utilizes the CD98hc (CD98 heavy chain, also known as SLC3A2) transporter, which is expressed on brain endothelial cells and mediates amino acid transport across the BBB:

style F fill:#e8f5e8
style G fill:#fff3e0
Key Steps:
- Targeting: BRAIN-enabled therapeutics are engineered with CD98hc-binding domains that selectively bind to the LAT1 (large neutral amino acid transporter 1) complex on brain endothelial cells
- Binding: CD98hc is a target-enriched transporter with restricted expression on BBB endothelium
- Transport: The cargo-receptor complex undergoes transcytosis across the endothelial cell
- Release: The therapeutic is released into the brain parenchyma where it can engage its CNS target
- Recycling: CD98hc is recycled back to the luminal surface for repeated transport
The CD98hc (SLC3A2) protein forms the heavy chain of the LAT1 (SLC7A5) heterodimeric amino acid transporter. LAT1 is one of the major amino acid transporters at the BBB and is upregulated in certain conditions:
- High expression: LAT1 is overexpressed on brain endothelial cells compared to peripheral endothelium
- Substrate scope: Transports large neutral amino acids, hormones, and therapeutic compounds
- Upregulation: Increased expression in neuroinflammation and some CNS disorders
- Tumor expression: Also overexpressed in many cancers, enabling targeted drug delivery
