AAT augmentation therapy, which alters disease symptoms, may also modulate AM epigenetics. To identify epigenetic regulation of AM inflammation in AATD in the context of AAT therapy, the investigators will perform and computationally integrate ChIP-seq and RNA-seq data. This will help elucidate the immunomodulatory mechanisms regulating AATD and provide an epigenetic map for diagnosis and targeted treatment. The investigators will test the efficacy of FDA-approved histone modifying drugs, such as SAHA and more specific next-generation histone modifiers, such as GSK-J4, to modulate AM AATD-associated activity ex vivo.
