Chimeric AAV vectors enabling antibody evasion and redosing for cardiac gene therapy

Chimeric AAV vectors enabling antibody evasion and redosing for cardiac gene therapy

Unmet Need Gene therapy using adeno-associated virus (AAV) vectors is severely limited by pre-existing immunity in 30–80% of adults and by the development of neutralizing antibodies after initial treatment, preventing redosing. There is a critical…

Rationally designed chimeric AAV capsids for enhanced immune evasion, cellular uptake, and transduction efficiency

Rationally designed chimeric AAV capsids for enhanced immune evasion, cellular uptake, and transduction efficiency

Unmet Need Adeno-associated virus (AAV) vectors are a leading platform for in vivo gene therapy, yet their clinical potential is limited by key biological barriers. Pre-existing immunity to common AAV serotypes diminishes vector efficacy and…

Viral-mediated humanized mouse model for Parkinson’s disease

Viral-mediated humanized mouse model for Parkinson’s disease

Unmet Need Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons in the midbrain and the accumulation of α-synuclein aggregates (Lewy bodies), leading to motor and cognitive impairments. PD…

A novel all-in-one AAV system for efficient epigenome editing in neurodegenerative diseases

A novel all-in-one AAV system for efficient epigenome editing in neurodegenerative diseases

Unmet Need Neurodegenerative diseases such as Alzheimer’s and Parkinson’s affect over 55 million people worldwide, with prevalence expected to double by 2050 due to aging populations. These conditions are progressive, debilitating, and currently have no…

Novel epigenome editors for multiplexed gene regulation

Novel epigenome editors for multiplexed gene regulation

Unmet Need Epigenome editors activate or inhibit gene expression without modifying the underlying DNA sequence. Consequently, these editors can reversibly fine-tune gene expression without the risk of permanently altering the genome or off-target editing. Epigenome…
