How do hundreds of proteins grip the cell’s actin skeleton? After 4 years of work, we discovered a tiny, 9-amino-acid conserved motif that acts as a universal molecular anchor—defining a whole new class of actin-binding proteins! Read it here: www.nature.com/articles/s41...

Nothing better for procrastination than going through some live cell imaging of Endosomes... Today we have the fusion of two equally sized PI(3)P positive endosomes. This is at 5s framerate, wish I had taken it at higher temporal resolution but still super cool to see

Phagocytic podosomes enable efficient uptake of Candida auris by primary human macrophages

Phagocytic podosomes enable efficient uptake of Candida auris by primary human macrophages
The yeast Candida auris is an emerging health threat. Sopelniak et al. show that uptake of C. auris cells by primary human macrophages involves the formation of phagocytic podosomes, highly dynamic actin structures that enable close adhesion to C. auris cells and are associated with proper maturation of respective phagosomes.

Podosomes in phagocytosis! 😋 + Candida auris Our new paper "Phagocytic podosomes enable efficient uptake of Candida auris by primary human macrophages" has now been published in Cell Reports: pubmed.ncbi.nlm.nih.gov/41863801/
C. auris-associated phagocytic podosomes share components and substructures with their “classic”, ECM-associated counterparts. Detected substructures and components include an F-actin-rich core (positive for Arp2 and cortactin), a cap structure on top of the core (positive for -actinin, zyxin, LSP1), a ring structure mediating adhesion to the phagocytic particle (containing vinculin, talin-1,  integrin), and a base near the plasma membrane (containing myosin 1f, WASp, MT1-MMP, DNAse X, and enriched in phospho-tyrosine residues). Individual phagocytic podosomes are linked by actomyosin filaments, similar to the connecting cables of ventral podosomes, thus establishing a flexible podosome array on phagosomes. The high turnover rate of phagocytic podosomes likely enables dynamic restructuring of the nascent phagocytic cup. In combination with establishing close adhesion to the pathogen surface, this likely mediates efficient internalization of C. auris cells in macrophages. Recruitment of degradative enzymes such as MT1-MMP or DNase X could, directly or indirectly, contribute to phagosome maturation and particle degradation.
