PROTACs eliminate, rather than inhibit, disease-driving proteins.They are bifunctional molecules that recruit an E3 ubiquitin ligase to tag the target protein for degradation by the proteasome. After the target is destroyed, the PROTAC is recycled to initiate further rounds of degradation.

In chronic inflammation, TL1A overexpression drives persistent T-cell activation, cytokine release, and tissue fibrosis. Blocking TL1A turns down both inflammation and fibrosis simultaneously. Unlike IL-23/IL-12 or JAK inhibitors, which act on narrower or systemic pathways, TL1A inhibition offers a dual anti-inflammatory and anti-fibrotic mechanism, engaging Th1, Th2, and Th17 pathways while enabling biomarker-guided, precision treatment with reduced immunosuppression risk.

MicroRNA therapeutics reprogram, rather than inhibit, disease biology.In many chronic and degenerative conditions, dysregulated microRNAs disrupt the cell’s natural gene-regulatory network, driving inflammation, fibrosis, and metabolic imbalance. By either restoring or silencing specific microRNAs, these therapies act upstream to rebalance entire gene networks, normalizing multiple disease pathways simultaneously. Unlike traditional RNA technologies such as mRNA or siRNA, which target single proteins or transcripts, microRNA therapeutics modulate coordinated gene networks, offering a systems-level approach to correcting disease.
