A part of my PhD work is now published in Nat Comm, describing the oligomerization mechanism of α-HL/Hla in the lipidic environment, answering a long-standing question. Last month, I presented this work at the 3DEM Gordon Research Conferences in Maine, USA.

Structural insights into pre-pore intermediates of alpha-hemolysin in the lipidic environment - Nature Communications
Staphylococcus aureus secretes pore-forming toxins, such as α-hemolysin, which damage the cell membranes. Here the authors describe the cryo-EM structures of the α-hemolysin pore, and pre-pores in lip...

🧬🎉Thrilled to share our new chromatin remodeling study! We reveal three states of human CHD1 and identify a novel "anchor element" that interacts with the acidic patch—conserved among remodelers. Our structures clarify mechanisms of remodeler recruitment! Link: authors.elsevier.com/a/1l2ik3vVUP...

The conserved HIV-1 spacer peptide 2 triggers matrix lattice maturation - Nature
A study reports that the structural maturation of the matrix domain of the Gag protein of HIV-1 is induced by the proteolytic release and binding of the spacer peptide SP2.
