The following antibodies show specificity for misfolded or aggregated TTR, which is critical in amyloidosis treatment:
NI301A: Demonstrated selective binding to ATTR in cardiac tissues from ATTR-CM patients. Ex vivo experiments showed macrophage-mediated clearance of ATTR deposits .
RT24: Reduced non-fibrillar TTR deposits in gastrointestinal tracts of FAP model rats and inhibited fibrillation in vitro .
No antibody labeled "ttr-3" is currently described in peer-reviewed literature or commercial catalogs.
Hypothetically, a "ttr-3" antibody might target a distinct conformational epitope (e.g., β-strand interfaces) or oligomeric TTR species.
Further studies are needed to map all cryptic epitopes and optimize antibody pharmacokinetics for clinical use.
