Cell Surface Markers Identify Astrocyte Subpopulations in the Adult Hippocampus With a Heterogeneous Response to Aging

Glia, Volume 74, Issue 11, November 2026.
ATP1B2 and GLAST identify two astrocyte subpopulations in the hippocampus with distinct molecular signatures. Transcriptomic shifts during aging differ between both subpopulations. Aged ATP1B2+ astrocytes rewire their metabolism while double‐positive aged astrocytes display a reduced synaptogenic capability.

Extracellular Vesicles for Space Biomedical Research

Journal of Extracellular Vesicles, Volume 15, Issue 11, November 2026.
Microgravity reshapes EV biogenesis and cargo selection, which brings new opportunities for longitudinal liquid‐biopsy readouts of stress and aging‐like trajectories, as well as the regenerative products in spaceflight research. ABSTRACT Extracellular vesicles (EVs) are regulated, information‐rich nanovesicles that reflect aspects of parent‐cell state,

The Efferocytosis‐Driven Macrophage Polarization: A Concerto in the Tumor Immunosuppressive Microenvironment

MedComm, Volume 7, Issue 11, November 2026.
Efferocytosis is a key process for macrophages to clear apoptotic cells, which undergoes the “ Find Me” chemotaxis signal stage, the “eat me” phagocytosis recognition stage and the “digest me” digestion stage in turn. During the aforementioned three stages, various signaling molecules released by apoptotic cells can promote the phenotypic polarization ...

Structural and biophysical investigations of Rab GTPase interacting proteins

, 2011
THESIS 9779Summary: Rab GTPases are important regulators of cell trafficking steps such as vesicle fusion, budding and motility. They are often described as \u27on/off\u27 switches, interacting with specific effectors when bound to GTP.

Exosomes in Cancer: The Biology, Function, Diagnosis, and Therapy

MedComm, Volume 7, Issue 11, November 2026.
Tumor‐derived exosomes and nonmembranous extracellular nanoparticles (exomeres/supermeres) constitute a heterogeneous communication network that drives cancer progression. By shuttling functional biomolecules across tissue‐specific barriers, these nanoparticles orchestrate local microenvironmental remodeling, immune suppression, premetastatic niche ...

Rab GTPase regulation of VEGFR2 trafficking and signaling in endothelial cells.

, 2009
Objective— Vascular endothelial growth factor receptor 2 (VEGFR2) is a receptor tyrosine kinase that regulates vascular physiology. However, mechanism(s) by which VEGFR2 signaling and trafficking is coordinated are not clear.

Mechanisms of XCR1 Membrane Trafficking and Constitutive Endocytosis

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 5, November 2026.
ABSTRACT Chemokines orchestrate immune cell trafficking through receptor‐mediated signalling and are implicated in inflammatory, autoimmune and neuropathic disorders. The XCL1–XCR1 axis is of particular interest because XCR1 is selectively expressed on mature conventional type 1 dendritic cells (cDC1s), where it supports communication with activated ...

Cargo Stability of Extracellular Vesicles Derived From Non‐Diseased Sources: Effects of Storage and Handling Conditions

Journal of Cellular and Molecular Medicine, Volume 30, Issue 21, November 2026.
ABSTRACT Extracellular vesicles (EVs) are nanoscale, membrane‐enclosed particles that transfer proteins, nucleic acids, lipids, and other bioactive molecules between cells. Their cargo‐bearing capacity supports applications in drug delivery, regenerative medicine, and biomarker development, but ex vivo handling can alter vesicle recovery and cargo ...
