Co-expression of PD-L1-specific chimeric switch receptors (CSRs) improves the antitumor effects of chimeric antigen receptor (CAR) T cells. Here, CSRs are shown to promote the differentiation of mesothelin-targeting CAR T cells into central memory-like cells and improve their efficacy.
Adipose tissue fibrosis is connected to obesity-related metabolic dysfunction. Qiu and colleagues discover that the Hippo pathway acts as a molecular switch in the initiation and development of adipose tissue fibrosis upon TGFβ stimulation.
Bedrock weathering is associated with landslides, and also manifests as a change in the strength of subsurface materials. This study analyzes inventoried landslides to explore relationships between strength and landslide depth as a potential reflection of subsurface weathering at large scales.
Various applications would benefit from the ability to continuously measure biomolecules. Here the authors describe a biosensing technology based on the free diffusion of biofunctionalized particles hovering over a sensor surface, which enables monitoring of analytes (pM-µM) over long timespans.
Controlling the selectivity of the chemical modification of a genetic-manipulation-free protein is currently problematic. Here the authors report a method using cysteine-based chemoselective Linchpin Directed site-selective Modification of the lysine residue in a protein.
Dietary sugar intake may contribute to the development non-alcoholic fatty liver disease. Here the authors investigated the effects of chronic dietary sucrose on the liver-adipose-microbiome axis in mice, and report that sex is a moderating factor that influences sucrose-driven lipid storage in the liver and adipose tissue lipolysis.
How different physical configurations between sarcomeres and mitochondria alter energetic support for contractile function of skeletal muscle is not clear. Here the authors use advanced 3D imaging and analysis techniques to show how space is made for mitochondria within the tightly packed sarcomere networks of striated muscle cells.
Post injury cytoskeletal modifications in neurons are not fully understood. Here the authors describe a pro-survival actin cytoskeletal reorganization in neurons triggered during a model of ischemic stroke.
Transplanting encapsulated insulin-producing cells may achieve a functional cure for type 1 diabetes, but efficacy is constrained by mass transfer limits. Here, the authors report a dynamic computational platform to investigate the therapeutic potency of such programmable bioartificial pancreas devices.
It is challenging to prepare electrolyte that could achieve wide electrochemical window, broad working temperature, non-inflammability, and fast ion transport simultaneously. Here the authors report a rocking-chair proton battery utilizing a solvent-free protic liquid electrolyte, which could operate in a broad temperature range from 0 to 250 celsius degree.
TGF-β has been shown to regulate stem-like CD8 + T cell differentiation into tissue resident memory T cells in chronic infection. Here authors show that in tumour-bearing mice, a similar TGF-βdependent CD8 + T cell differentiation program is carried out in the draining lymph nodes, which impedes generation of anti-tumor migratory effector T cells upon future vaccination.
Metastable helium is a promising target for remote-sensing observations of Earth’s thermosphere. This paper reports on the development of a resonance lidar capable of resolving metastable helium density profiles and presents initial results
Uropathogenic strains of Escherichia coli (UPEC) are a leading cause of urinary tract infections (UTIs) and invasion involves Rho GTPase members, notably Rac1, to drive actin cytoskeleton rearrangement leading to engulfment. Here, Petracchini et al. provide evidence of an ECM stiffnessmodulated role of Optineurin (OPTN), which regulates HACE1-dependant Rac1 activity and thus controls integrinmediated mechanotransduction and bacterial invasion.
In this study the authors report that Caldesmon controls force-balance and architecture of stress fibers through dynamic cross-linking of actin and myosin filaments. Caldesmon depletion led to consequent problems in cell morphogenesis, motility and mechanosensing.
Endogenous retroviruses (ERV) are inherited remains of retroviruses that have colonized host genomes during evolution. Here the authors observe considerable species-specific ERV variation among Darwin’s finches, reflecting historic retrovirus-host interactions.
Long-distance regeneration in the adult central nervous system shows severe guidance defects preventing circuit reformation. Here, the authors reveal a comprehensive map of guidance cues in the adult visual system that can be used to modulate the path of regenerating axons to achieve circuit repair.
Reference genomes for gut microbiomes help unravel microbial “dark matter” and serve as valuable resource for disease-focused studies. Here, the authors perform short and long read metagenomics and metagenome-assembled genomes analyses to profile the gut microbiome of Southeast Asian populations, revealing significant species and strain-level diversity, with thousands of previously uncharacterized biosynthetic gene clusters.
Retinal pigment epithelium (RPE) plays an important role in diabetic retinopathy (DR) progression. Here, the authors show AKT1 and AKT2 are reciprocally regulated in the RPE of DR donor tissue and diabetic mice, reducing Akt2 in RPE causing a compensatory increase in Akt1 and attenuating DR.
Spontaneous low-frequency oscillations, which are a feature of biological systems, are challenging to engineer into microrobotic systems. The authors discover a mechanism for asymmetry-induced order and realise electrical and mechanical oscillations in a particle collective to power a microrobotic arm.
The molecular and cellular underpinnings of cribriform prostate cancer aggressiveness remain to be explored. Here, the authors perform single-cell RNA-sequencing, TCR sequencing and histology and reveal cancer cell intrinsic pathways and an immunosuppressive tumour microenvironment.
