Gotta believe in your product!

Congrats to Shubhra Jyoti Saha on leading this very successful project in the lab, and our collaborators for making this work possible. Many thanks to NIH Office of AIDS Research and the NIH IRP (NIDDK and NIAID) for supporting this work.

They also retain strong activity against every strain of HIV tested. Such conjugates are even more potent than monoclonal antibodies and fusion inhibitor peptides applied in the clinic.

This was a collaboration with the Bewley and Doria-Rose labs at NIH IRP. Linking fusion inhibitor peptides, which block HIV viral infection with modest potency, to single domain antibodies for delivery to the cell surface, leads to enormous enhancements in antiviral potency (up to 10,000-fold!)

Proposed mechanism of receptor-dependent activity of bitopic ligands. Structures of PTHR1 and A2AR used in this panel were generated using Alphafold2.

Bitopic ligands comprise a #pharmacophore & a linked moiety that bind to separate sites. @rche54.bsky.social &co show that #GPCRs that bind small molecules can be potently activated by #bitopic #nanobody -ligand conjugates to selectively target pairs of GPCRs @plosbiology.org 🧪 plos.io/4p3VOyH

It’s really meaningful to have such insightful coverage from a leader in the field @zenbrainest.bsky.social and Xianglin Huang. We appreciate the time they took to write up this very nice commentary!

So cool to read this commentary that covers our recent work!

Thanks Anirban! Glad to see this work released

ii. Recognition that these nanobody-ligand conjugated only show activity when both the nanobody AND ligand targets are expressed (logic gated signaling). This should be useful for delivering molecules with widely expressed targets only to cells of choice! Congrats to Shivani Sachdev and Swarnali Roy

This work described for the first time two new directions we are excited to explore: I. nanobody-small molecule conjugates as a sort of analogue of traditional antibody-drug conjugates but we are targeting GPCRs at the cell surface instead of intracellular targets.

So pleased to share the final version of this work published in @plosbiology.org ! journals.plos.org/plosbiology/...

Read this in a paper and it was totally new to me (after 18 years in biochemistry research): “Peptides translated from the sense and antisense strands of DNA interact specifically, analogous to the complementary interactions between DNA double strands.” Is this widely studied/actually true?? 🤯

It's been a while since I posted on some of the ☢️ #radiopharmaceuticals ☢️ work we've been brewing.

Let's fix that...

The findings suggest that optimizing input parameters and refining competition-based modeling approaches may enhance predictive accuracy for antibody-antigen interactions. Intriguing.

Finally we compared models of nanobody-epitope to nanobody-antigen complexes. In one case Alphafold produced an accurate model with epitope but failed with antigen! This highlights the potential utility of simplifying Alphafold inputs for generating models with improved accuracies (4/4)
