Biological organisms engineer peptide sequences to fold into membrane pore proteins capable of performing a wide variety of transport functions. Synthetic de novo-designed membrane pores can mimic this approach to achieve a potentially even larger set of functions. Here we explore water, solute, and ion transport in three de novo designed β-barrel membrane channels in the 5-10 Å pore size range.

Methods: Patients age ≥60 years with newly diagnosed, any stage, cHL were treated with six cycles of AVD at standard doses plus nivolumab 240 mg intravenously once every 2 weeks (on days 1 and 15) of each cycle.
Dynamin 1 (Dyn1) GTPase, a principal driver of membrane fission during synaptic endocytosis, self-assembles into short mechanoactive helices cleaving the necks of endocytic vesicles. While structural information about Dyn1 helix is abundant, little is known about the nanoscale dynamics of the helical scaffolding at the moment of fission, complicating mechanistic understanding of Dyn1 action. To address the role of the helix dynamics in fission, we used High-Speed Atomic Force Microscopy (HS-AFM) and fluorescence microscopy to track and compare the spatiotemporal characteristics of the helices formed by wild-type Dyn1 and its K44A mutant impaired in GTP hydrolysis on minimal lipid membrane templates.

- - Chlamydia is a widespread bacterial STD that often goes unnoticed, creating a need for a preventive vaccine to address its serious health risks.
- - Cell-free protein synthesis (CFPS) allows for quick and adaptable production of vaccine proteins, demonstrated by producing the chlamydial CT584 protein for testing in mice.
- - Although CT584 prompted strong antibody responses, it failed to effectively protect against chlamydia infection, highlighting CFPS's potential for producing other antigens even if this candidate wasn't successful.
