Experimental measurement of endocytosis in fungal hyphae. [PDF]

open access: yes, 2018
The present study examines the notion that polarized exocytosis in the tips of growing hyphae creates an excess of plasma membrane and thus the need for its removal by endocytosis.

HID-1 controls formation of large dense core vesicles by influencing cargo sorting and trans-Golgi network acidification [PDF]

open access: yes, 2017
Large dense core vesicles (LDCVs) mediate the regulated release of neuropeptides and peptide hormones. They form at the trans-Golgi network (TGN), where their soluble content aggregates to form a dense core, but the mechanisms controlling biogenesis are ...

Intrinsically Disordered Protein‐Inspired Nanovector‐Based Coacervates for the Direct Cytosolic Transport of Biomacromolecules

open access: yesAdvanced Materials, EarlyView.
Intrinsically disordered protein‐inspired nanovectors (IDP‐NVs) form stable nanocoacervates (NCs) with diverse biomacromolecules. In situ conformational changes confer stability and adaptability to NCs under dynamically changing physiological conditions.

A novel function of Noc2 in agonist-induced intracellular Ca2+ increase during zymogen-granule exocytosis in pancreatic acinar cells.

open access: yesPLoS ONE, 2012
Noc2, a putative Rab effector, contributes to secretory-granule exocytosis in neuroendocrine and exocrine cells. Here, using two-photon excitation live-cell imaging, we investigated its role in Ca(2+)-dependent zymogen granule (ZG) exocytosis in ...

Exocytosis of the silicified cell wall of diatoms involves extensive membrane disintegration

open access: yesNature Communications, 2023
Exocytosis is a fundamental cellular process. Here, the authors report an unusual exocytosis mechanism in the silicified cell wall of diatoms, in which membrane patches are discarded.

Molecular medicine of microRNAs: structure, function and implications for diabetes [PDF]

open access: yes, 2008
MicroRNAs (miRNAs) are a family of endogenous small noncoding RNA molecules, of 19–28 nucleotides in length. In humans, up to 3% of all genes are estimated to encode these evolutionarily conserved sequences.

Multiphysics‐Driven Assembly of Biomimetic Vesicles

open access: yesAdvanced Materials, EarlyView.
Artificial extracellular vesicles, derived from cell membranes, are manufactured using a multiphysics‐integrated microfluidic platform that combines nanoknife membrane rupture, herringbone chaotic mixing, and acoustothermal modulation. This standardizable workflow enables the predictable control of vesicle formation and therapeutic loading, while ...

JNK signaling coordinates epithelial cell turnover through exocytosis in Drosophila ribosomal protein mutants

open access: yesiScience
Summary: Robust tissue growth is orchestrated by the precise coordination of cell death and cell proliferation. In the developing wing pouches of Drosophila Minute/+ animals, both cell death and compensatory cell proliferation are increased, thereby ...

FM1-43 reveals membrane recycling in adult inner hair cells of the mammalian cochlea [PDF]

open access: yes, 2002
Neural transmission of complex sounds demands fast and sustained rates of synaptic release from the primary cochlear receptors, the inner hair cells (IHCs). The cells therefore require efficient membrane recycling.

Formation of Condition‐Dependent Alpha‐Synuclein Fibril Strain in Artificial Cerebrospinal Fluid

open access: yesAdvanced Science, EarlyView.
α‐synuclein aggregation in artificial cerebrospinal fluid (aCSF) leads to a distinct conformation with an electron density pocket motif found in aggregates from PD and MSA patients. Such fibrils has low stability outside the reaction conditions, hinting about the influence of cerebrospinal fluid components not only on the formation, but also on the ...
