Outer membrane protein assembly mediated by BAM-SurA complexes.

The outer membrane is a formidable barrier that protects Gram-negative bacteria against environmental threats. Its integrity requires the correct folding and insertion of outer membrane proteins (OMPs) by the membrane-embedded β-barrel assembly machinery (BAM). Unfolded OMPs are delivered to BAM by the periplasmic chaperone SurA, but how SurA and BAM work together to ensure successful OMP delivery and folding remains unclear.

Structural basis for CCR6 modulation by allosteric antagonists.

The CC chemokine receptor 6 (CCR6) is a potential target for chronic inflammatory diseases. Previously, we reported an active CCR6 structure in complex with its cognate chemokine CCL20, revealing the molecular basis of CCR6 activation. Here, we present two inactive CCR6 structures in ternary complexes with different allosteric antagonists, CCR6/SQA1/OXM1 and CCR6/SQA1/OXM2.

Pembrolizumab-induced Myasthenia Gravis and Myocarditis.

As the use of immune checkpoint inhibitors (ICPi) such as pembrolizumab is rapidly expanding in the field of immuno-oncology, it is crucial for healthcare providers to be aware of their immune-related adverse events (irAE) which are thought to be driven by augmented immune response of T-cells. While neurologic irAE are underrepresented in literature, their consequences could lead to fatal outcomes. In this report, we describe the case of a patient with excellent performance status prior to pembrolizumab therapy who subsequently suffered myasthenic crisis eventually requiring tracheostomy and long-term mechanical ventilation.
