Precision LINE-1 medicine

Silencing the
virus within

L1 Therapeutics is developing precision therapies that suppress LINE-1 - an ancient virus-like element in the human genome that reactivates under stress and contributes to disease

Targeting LINE-1, an ancient virus-like element in the human genome

When LINE-1 reactivates under stress, it drives genomic instability and an innate immune reaction. Because LINE-1 stays quiet in healthy tissue, inhibitors primarily target disease-causing cells

Therapeutic strategy

New technology now lets us identify diseases where LINE-1 activity is treatable. We focus on conditions that show genomic signs of ongoing, active LINE-1 biology contributing significantly to disease

Open-source retrotransposon mining

retrotransposon-miner is our open-source software for finding mobile DNA insertions in genomic data. It detects insertions that earlier methods miss, including events previously thought to require long-read sequencing or that were not detectable before
