GSK-3 inhibitors and DYRK1A inhibitors are both types of drugs that can affect the phosphorylation of tau protein, which is involved in neurodegenerative diseases such as Alzheimer’s 1 2. However, they have different mechanisms of action and targets. GSK-3 inhibitors block the activity of GSK-3 enzymes, which are responsible for adding phosphate groups to tau and other proteins 1 3. DYRK1A inhibitors block the activity of DYRK1A kinase, which is responsible for priming tau protein for further phosphorylation by GSK-3 and promoting tau aggregation 2 4. Therefore, they have some common functionality in reducing tau phosphorylation, but they also have distinct effects on other signaling pathways.

input: do they work on shared pathway?

Yes, they do work on a shared pathway. As I mentioned before, DYRK1A phosphorylates tau protein at certain sites that make it more susceptible to further phosphorylation by GSK-3 1 2. This means that inhibiting either DYRK1A or GSK-3 can reduce the overall level of tau phosphorylation and aggregation, which is associated with neurodegeneration 3 1. However, they also have different effects on other pathways that are involved in neuronal survival, growth, and plasticity 3 . Therefore, they may have synergistic or antagonistic effects depending on the context and the disease.

I see. In that case, you may be interested in a study that showed that inhibition of both DYRK1A and GSK3B induced human beta cell proliferation and improved glucose homeostasis in diabetic mice 1. The authors suggested that DYRK1A and GSK3B act as negative regulators of beta cell cycle progression and survival, and that their inhibition can overcome the replication block in adult beta cells 1. However, this is only one study and more research is needed to confirm the safety and efficacy of this approach.
