Huntington's Disease Overview
🧬 Huntington's disease is a genetic brain disorder caused by mutations in the HTT gene.
🧠 This mutation leads to the production of a toxic protein resulting in the progressive death of neurons in the brain.
😥 The disease severely impacts an individual's ability to move, mood, and cognitive functions, causing immense difficulty for both patients and caretakers.
👨‍👩‍👧‍👦 There is a 50/50 chance of passing the disease on to children due to its genetic nature.

Gene Therapy Approaches
🔬 Gene therapy aims to treat Huntington's by lowering the production of the toxic HTT protein, potentially slowing neural breakdown.
🦠 One main clinical approach uses microRNAs (miRNAs), short RNA molecules delivered via modified viral vectors to inhibit the mutant huntingtin protein production.
🧵 The alternative method involves antisense oligonucleotides (ASOs), which are synthetic DNA/RNA mimics that bind to the faulty HTT gene to block harmful protein expression.
💊 A key distinction is that ASOs typically require multiple doses, whereas miRNA therapies aim for a single administration.

Key Points & Insights
➡️ Gene therapy offers hope for Huntington's disease, which currently lacks a cure or effective treatment.
➡️ MicroRNAs function as a check-and-balance system by destroying messenger RNA responsible for protein production.
➡️ Researchers are actively working in clinical trials to develop safe and effective methods to slow disease progression.
