We review recent progress in the study of the structure and dynamics of phospholipid membranes and associated proteins, using novel label-free analytical tools. We describe these techniques and illustrate them with examples highlighting current capabilities and limitations. Recent advances in applying such techniques to biological and model membranes for biophysical studies and biosensing applications are presented, and future prospects are discussed.

The cell nuclei of Ophisthokonts, the eukaryotic supergroup defined by fungi and metazoans, is remarkable in the constancy of their double-membraned structure in both somatic and germ cells. Such remarkable structural conservation underscores common and ancient evolutionary origins. Yet, the dynamics of disassembly and reassembly displayed by Ophisthokont nuclei vary extensively.

Background & Aims: Metabolic dysfunction-associated steatotic liver (MASLD) progression is driven by chronic inflammation and fibrosis, largely influenced by Kupffer cell (KC) dynamics, particularly replenishment of pro-inflammatory monocyte-derived KCs (MoKCs) due to increased death of embryo-derived KCs. Adenosine A3 receptor (A3AR) plays a key role in regulating metabolism and immune responses, making it a promising therapeutic target. This study aimed to investigate the impact of selective A3AR antagonism for regulation of replenished MoKCs, thereby improving MASLD.

R-loops are critical structures that play pivotal roles in regulating genomic stability and modulating gene expression. This study investigates the interactions between the 5-methylcytosine (mC) methyltransferase NOP2/Sun RNA methyltransferase 2 (NSUN2) and R-loops in the transcriptional dynamics and damage repair process of bladder cancer (BCa) cells. We observed markedly elevated levels of R-loops in BCa cells relative to normal urothelial cells.
