Integrated Engineering of CAR‐T Cells for Solid Tumours
Solid tumours pose multifactorial barriers including antigen heterogeneity, immunosuppressive microenvironment, and poor T‐cell trafficking, limiting CAR‐T efficacy compared to hematologic malignancies. Integrated engineering strategies are essential, combining logic‐gated receptors for precision, metabolic‐epigenetic reprogramming for resilience, and ...

Proteostasis of organelles in aging and disease
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Histone chaperone regulates replication
Histone supply and demand are tightly coupled at the replication fork by a chaperone, according to Genevieve Almouzni (Curie Institute, Paris, France) and colleagues. The chaperone, Asf1, passes histones from parental to daughter DNA strands and unwinds just enough DNA to match its transfer activities.

Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

Biogenesis of TNF‐α‐insights into proteostasis and inflammation
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Tipping the balance in histone supply puts genome stability at stake
Specific localization of the histone H3 variant CENP-A at centromeres is key for faithful chromosome segregation during cell division, with CENP-A mislocalization being associated with chromosomal instability and cancer.

Stimulating proteasomal degradation in human proteinopathies
The proteasome mediates the degradation of a wide range of proteins. Boosting proteasomal degradation may be beneficial in several disease contexts and can be achieved either by modulating proteasome activity or by improving substrate delivery. Proteasome activity can be enhanced by increasing proteasome abundance, inducing constitutive gate opening ...

Combating ageing beyond the cell: Emerging roles of extracellular proteostasis
Ageing challenges the body's ability to maintain a stable and functional proteome, leading to protein damage and aggregation both inside and outside cells. This review focuses on the less well understood mechanisms of extracellular protein quality control and how they become disrupted in ageing, particularly in neurodegenerative diseases.

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Aire and Fezf2 Shape the Medullary Thymic Epithelial Cell Immunopeptidome for Central Tolerance
Central tolerance is shaped not merely by promiscuous gene expression in medullary thymic epithelial cells (mTECs), but by the subset of self‐peptides ultimately presented on MHC class II molecules. We propose a multilayered framework in which AIRE/Aire and FEZF2/Fezf2, together with specialised differentiation programmes—including thymic mimetic‐cell ...
