Endocytosis in plants: fact or artefact?

open access: yes, 1995
Whilst plant cells are apparently equipped with all the necessary molecular machinery for receptor-mediated endocytosis, the physiological role of this process in these cells remains an enigma. In this article, we consider current opinions of endocytosis

Functional analysis of TOR complex 2 and its control of sphingolipid biosynthesis in "Saccharomyces cerevisiae" [PDF]

open access: yes, 2006
sphingoid base, one of the intermediate of sphingolipids metabolites, plays a key role as a signaling molecule which activate PKH kinases and its substrates YPKs and PKC1 (Casamayor, Torrance et al. 1999; Friant, Lombardi et al.

Activity-dependent bulk endocytosis: control by molecules and signalling cascades [PDF]

open access: yes, 2017
Synaptic vesicle (SV) recycling in the presynapse is essential for the maintenance of neurotransmission. During mild stimulation clathrin-mediated endocytosis (CME) dominates, however during intense stimulation activity-dependent bulk endocytosis ...

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Feeding Mechanisms of Pathogenic Protozoa with a Focus on Endocytosis and the Digestive Vacuole

open access: yesParasitologia
Endocytosis is a quintessential feature of eukaryotes, and the emergence of endocytosis played a major role in the origin and evolution of eukaryotes.

Clathrin-independent but dynamin-dependent mechanisms mediate Ca2+-triggered endocytosis of the glutamate GluK2 receptor upon excitotoxicity [PDF]

open access: yesJournal of Integrative Neuroscience, 2020
We first explore the features of GluK2 endocytosis during kainate excitotoxicity and then explore the role of Ca2+ in the regulation of GluK2 endocytosis. The roles of Ca2+ were examined by treating cells with Ca2+ inhibitors or chelators.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Bile acids reduce endocytosis of high-density lipoprotein (HDL) in HepG2 cells.

open access: yesPLoS ONE, 2014
High-density lipoprotein (HDL) transports lipids to hepatic cells and the majority of HDL-associated cholesterol is destined for biliary excretion. Cholesterol is excreted into the bile directly or after conversion to bile acids, which are also present ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Synaptic Vesicle Endocytosis in Different Model Systems

open access: yesFrontiers in Cellular Neuroscience, 2018
Neurotransmission in complex animals depends on a choir of functionally distinct synapses releasing neurotransmitters in a highly coordinated manner. During synaptic signaling, vesicles fuse with the plasma membrane to release their contents. The rate of
