AbstractSerpins, protease inhibitors whose regulated conformational instability renders them susceptible to mutations that cause misfolding, represent a system for the study of non-amyloid protein aggregation. The E342K “Z” variant of α-1-antitrypsin (AAT) undergoes oligomeric self-assembly into polymer chains that are associated with liver and lung pathologies in AAT deficiency.

AbstractConjugated polymers are widely studied for application areas ranging from energy technology to wearable electronics and bioelectronics. To develop a truly sustainable technology, environmentally benign synthesis is essential. Here, the open-flask synthesis of a multitude of conjugated polymers at room temperature by ambient direct arylation polymerization (ADAP) is demonstrated.

AbstractCell-to-cell communication is essential for multicellular organisms. Plasmodesmata (PD) are plant-specific nanopore structures pivotal for cell-to-cell communication and plant survival. However, how PD form and their structure, regulation, and evolution remain largely unknown. Here, we demonstrate that the exogenous supply of abscisic acid (ABA), a well-conserved phytohormone in land plants, reduces primary PD density in the moss Physcomitrium patens.
