🍄🦇New Preprint from the lab!🦇🍄 We wondered what the role of calcineurin is in Pd biology using inhibitors and found: 1) Pd seems to be intrinsically resistant to FK506! 2) Calcineurin is involved in Pd response to voriconazole. 3) Calcineurin inhibition improves Pd growth in micafungin.

That is a good question! The 2 drugs that we used are clinical immunosuppressants, so if they behave as they do in humans, I guess that they would also immunosuppress bats (but that is a huge assumption). Fungal & mammal calcineurin are a tad different; hopefully, it can be exploited to fight fungi
