Cheloha builds nanobody-GPCR ligand conjugates that rescue weak peptides, engineer receptor selectivity And can selectivity for one receptor subtype be engineered without redesigning the ligand from scratch Conformation selectivity changes the duration of the signal PTH receptor exists in G-protein coupled Attaching a short PTH fragment to a PTHR1-selective nanobody produces a ligand selective for that subtype ; the same fragment attached to a PTHR2-selective nanobody redirects it entirely.

John Streicher on how HSP90 flips direction between brain and spinal cord, why isoform-selective inhibitors Current lines of work include isoform-selective HSP90 inhibition as a strategy for widening the opioid The "brain always wins" problem is solved by isoform selectivity, not by dose. With a non-selective HSP90 inhibitor given systemically, the brain effect dominates and pain relief is The route from "intrathecal only" to "oral pill" runs through isoform selectivity.
