Trimodal Single-Cell Profiling Reveals a Novel Pediatric CD8αα+ T Cell Subset and Broad Age-Related Molecular Reprogramming across the T Cell Compartment
[Nature Immunology] The authors profiled >300,000 single T cells from healthy children and older adults by using the trimodal assay TEA-seq, which revealed that molecular programming of T cell subsets shifted toward a more activated basal state with age.

Functional Diversification and Dynamics of CAR-T Cells in Patients with B-ALL
[Cell Reports] Investigators constructed a longitudinal high-precision single-cell transcriptomic landscape of 7,578 CAR-T cells from 26 patients with B cell acute lymphoblastic leukemia post-infusion.

Silicon-Based Biomaterials Modulate the Adaptive Immune Response of T Lymphocytes to Promote Osteogenesis/Angiogenesis via Epigenetic Regulation
[Advanced Healthcare Materials] Mesoporous silica was used as a model material of Si-based biomaterials. Experiments showed that the supernatant of CD4+ T lymphocytes pretreated with mesoporous silica extract significantly promoted the vascularized bone regeneration.

An ULK1/2-PXN Mechanotransduction Pathway Suppresses Breast Cancer Cell Migration
[EMBO Reports] Researchers described a new role for the autophagy-inducing serine/threonine kinases ULK1 and ULK2 in mechanotransduction, and showed that ULK1/2 activity inhibited the assembly of actin stress fibers and focal adhesions.

Defined Extracellular Matrix Compositions Support Stiffness-Insensitive Cell Spreading and Adhesion Signaling
[Proceedings Of The National Academy Of Sciences Of The United States Of America] To address the functional coupling of ECM composition and matrix rigidity on compliant substrates, investigators developed a matrix spot array system to screen cell phenotypes against different ECM mixtures on defined substrate stiffnesses at high resolution.

ECM Proteins and Cationic Polymers Coating Promote Dedifferentiation of Patient-Derived Mature Adipocytes to Stem Cells
[Biomaterials Science] To understand the role of physicochemical surface effects on the dedifferentiation of patient-derived mature adipocytes, the surfaces of cell culture flasks were coated with extracellular matrix, basement membrane proteins, and cationic/anionic polymers.
