Lamins: The backbone of the nucleocytoskeleton interface
Curr Opin Cell Biol. 2024 Feb;86:102313. doi: 10.1016/j.ceb.2023.102313. Epub 2024 Jan 22.ABSTRACTThe nuclear lamina (NL) is a crucial component of the inner nuclear membrane (INM) and consists of lamin filaments and associated proteins. Lamins are type V intermediate filament proteins essential for maintaining the integrity and mechanical properties of the nucleus. In human cells, 'B-type' lamins (lamin B1 and lamin B2) are ubiquitously expressed, while 'A-type' lamins (lamin A, lamin C, and minor isoforms) are expressed in a tissue- and development-specific manner. Lamins homopolymerize to form filaments that localize pr...

Membrane fusion and fission during eukaryogenesis
Curr Opin Cell Biol. 2024 Feb;86:102321. doi: 10.1016/j.ceb.2023.102321. Epub 2024 Jan 14.ABSTRACTAll eukaryotes can be traced back to a single shared ancestral lineage that emerged from interactions between different prokaryotic cells. Current models of eukaryogenesis describe various selective forces and evolutionary mechanisms that contributed to the formation of eukaryotic cells. Central to this process were significant changes in cellular structure, resulting in the configuration of a new cell type characterized by internal membrane compartments. Additionally, eukaryogenesis results in a life cycle that relies on cell...

Cellular stress management by caspases
Curr Opin Cell Biol. 2024 Feb;86:102314. doi: 10.1016/j.ceb.2023.102314. Epub 2024 Jan 11.ABSTRACTCellular stress plays a pivotal role in the onset of numerous human diseases. Consequently, the removal of dysfunctional cells, which undergo excessive stress-induced damage via various cell death pathways, including apoptosis, is essential for maintaining organ integrity and function. The evolutionarily conserved family of cysteine-aspartic-proteases, known as caspases, has been a key player in orchestrating apoptosis. However, recent research has unveiled the capability of these enzymes to govern fundamental cellular process...

Staying away from the breaking point: Probing the limits of epithelial cell elimination
Curr Opin Cell Biol. 2024 Feb;86:102316. doi: 10.1016/j.ceb.2023.102316. Epub 2024 Jan 9.ABSTRACTEpithelial tissues are dramatically remodelled during embryogenesis and tissue homeostasis and yet need to maintain their sealing properties to sustain their barrier functions at any time. Part of these remodellings involve the elimination of a large proportion of cells through apoptosis. Cell extrusion, the remodelling steps leading to seamless dying cell expulsion, helps to maintain tissue cohesion. However, there is an intrinsic limit in the system that can only accommodate a certain proportion/rate of cell elimination as we...

Jagged-mediated development and disease: Mechanistic insights and therapeutic implications for Alagille syndrome
Curr Opin Cell Biol. 2024 Feb;86:102302. doi: 10.1016/j.ceb.2023.102302. Epub 2024 Jan 9.ABSTRACTNotch signaling controls multiple aspects of embryonic development and adult homeostasis. Alagille syndrome is usually caused by a single mutation in the jagged canonical Notch ligand 1 (JAG1), and manifests with liver disease and cardiovascular symptoms that are a direct consequence of JAG1 haploinsufficiency. Recent insights into Jag1/Notch-controlled developmental and homeostatic processes explain how pathology develops in the hepatic and cardiovascular systems and, together with recent elucidation of mechanisms modulating l...

Engineering physiological environments to advance kidney organoid models from human pluripotent stem cells
Curr Opin Cell Biol. 2024 Feb;86:102306. doi: 10.1016/j.ceb.2023.102306. Epub 2024 Jan 9.ABSTRACTDuring embryogenesis, the mammalian kidney arises because of reciprocal interactions between the ureteric bud (UB) and the metanephric mesenchyme (MM), driving UB branching and nephron induction. These morphogenetic processes involve a series of cellular rearrangements that are tightly controlled by gene regulatory networks and signaling cascades. Here, we discuss how kidney developmental studies have informed the definition of procedures to obtain kidney organoids from human pluripotent stem cells (hPSCs). Moreover, bioenginee...
