Summary: This study reveals the critical role of RME-8/DNAJC13 protein in maintaining lysosomal capacity and autophagy, particularly in neurons. Loss of RME-8/DNAJC13 leads to abnormal accumulation of autolysosomal tubules in both C. elegans and primary mouse cortical neurons, and affects the process of autophagy. These findings provide insights into the potential impact of RME-8/DNAJC13 on neuronal health and the progression of neurodegenerative diseases.

Summary: Sucrose induces cell elongation and endocytosis in plant roots, and its regulation is reversible. The endocytosis mediated by sucrose is dependent on clathrin-mediated mechanism and plays a role in sensing energy status and signaling root elongation.

Summary: Clathrin is a crucial cytosolic protein involved in intracellular trafficking, mitosis, and cell signaling. Comprising of heavy and light chains, it forms triskelions that polymerize into clathrin coated vesicles for membrane transport. Despite the well-documented role of heavy chains, the regulation of membrane traffic and cell signaling by clathrin light chains remains incompletely understood.

Summary: In this study, a novel regulator called gamma-taxilin was found to be involved in Hook1-mediated endosomal sorting. Gamma-taxilin negatively regulates the sorting of cargo proteins by interfering with the interactions between Hook1 and the cargo proteins.

Summary: This study demonstrates that intracellular clathrin-coated vesicle (CCV) formation can be induced using minimal machinery in living cells, and it can occur on various membranes. The study also shows that the formation of these vesicles, called MitoPits, can faithfully recapitulate all stages of CCV formation without the involvement of accessory proteins.

Summary: MR1 is a conserved microbial immune-detection system in mammals that presents antigens to specific lymphocytes, contributing to host defense and tissue repair. This study reveals that human MR1 interacts with the endocytic adaptor protein 2 (AP2) complex to regulate its internalization from the cell surface, thus controlling antigen presentation and microbial metabolic detection.

Summary: This study found that the endocytosis of synaptic vesicles in mouse hippocampal neurons at physiological temperature is independent of clathrin, while the endocytic retrieval of certain synaptic vesicle proteins, including vesicular transporters for glutamate and GABA, relies on sorting by the clathrin adaptor AP-2.

Summary: The development of tumors is associated with spontaneous dimerization and dysregulation of EGFR signaling. Attenuation of EGFR signaling is necessary for normal cell growth, and resistance to current treatment strategies can occur due to alterations in EGFR trafficking. Targeting EGFR trafficking may aid in the treatment of cancer.

Summary: The study reveals that regulating the copy number of the noncanonical vesicular SNARE protein VAMP4 on synaptic vesicles is crucial for controlling neurotransmitter release probability. VAMP4, with high synaptic turnover, is selectively sorted to endolysosomes during activity-dependent bulk endocytosis, disrupting which can lead to an increase in VAMP4 abundance in the SV pool and inhibition of SV fusion.

Summary: Trypanosoma brucei is a unicellular pathogen that thrives extracellularly in vertebrate hosts, with its cell surface playing a critical role in both immune recognition and evasion. The variant surface glycoprotein (VSG) and incessant motility contribute to immune evasion, while endo- and exocytosis occur at the flagellar pocket. Mechanisms behind VSG recycling and secretion are not fully understood, presenting longstanding questions that may be answered with novel technologies in the future.

Summary: Endocytosis is a crucial process for cell health and signaling, specifically clathrin mediated endocytosis (CME) plays a key role in synaptic vesicle recycling and intracellular communication in the brain. This review focuses on clathrin and dynamin, two proteins involved in CME, and discusses the potential therapeutic interventions and inhibitors for conditions involving defects in CME.

Summary: This study reveals the mechanism by which the recycling protein RME-8 regulates microdomain segregation in endosomes. We found that RME-8 is inhibited on endosomal membranes by homo-oligomerization until it is activated by companion recycling protein SNX-1. This activation allows RME-8 to uncoat both degradative sorting proteins and its own activator SNX-1, limiting the range of microdomains and providing negative feedback regulation. The results suggest that RME-8 and SNX-1 play important roles in an expansive recycling machinery, and there is still much exciting work to be done to uncover their functions within this broader context.

Summary: A BR binding-deficient Arabidopsis mutant was designed to re-examine the BRI1 endocytosis and signal attenuation model. The study showed that despite impaired phosphorylation and ubiquitination, the BR binding-deficient BRI1 can still internalize, indicating that BRI1 internalization relies on different endocytic machineries. Furthermore, the mutant provides opportunities to study non-canonical ligand-independent BRI1 functions.

Summary: Endocytosis, beyond its canonical function of molecule internalization, plays a crucial role in regulating cell signalling spatiotemporally. It controls various cellular processes, including cell migration and polarity, with its deregulation being implicated in diseases like cancer. Recent studies have shown that endocytosis and subsequent trafficking routes have a significant impact on signal transmission regulation, affecting cell physiology and pathology.

Summary: Cell migration is guided by cues from the environment, which are detected by receptors at the cell surface. Clustering of these receptors on the plasma membrane facilitates the translation of information into phenotypic changes. Clathrin-coated structures provide a mechanism for controlling receptor availability, and play a role in defining migration direction through feedback loop mechanisms.

Summary: This study aims to evaluate the influence of anesthetic modality (local anesthesia (LA) vs. general anesthesia (GA)) on the risk of neurological injury during lower third molar extraction. A systematic search identified 6 studies, of which 4 reported a correlation between GA and nerve damage. Two studies did not show an obvious association. Overall, the literature lacks scientific evidence, but based on the risk-benefit ratio, LA should be preferred for lower third molar surgery.

Summary: This study compared the maxillomandibular growth changes in growing subjects with Class I and II skeletal relationships, using the modified third finger middle phalanx maturation (MPM) method. The results showed that there were no significant differences between the two groups, except for the sagittal maxillomandibular relationship parameters. It was found that mandibular deficiency was mostly established during the prepubertal growth stage and further aggravated during puberty in subjects with a Class II relationship.

Summary: This study investigates the role of group IIA secreted phospholipase A(2) (sPLA(2)-IIA) in osteoclast bone-resorption activity and syncytium formation. The results suggest that sPLA(2)-IIA is involved in the regulation of osteoclast maturation and fusion through both catalytic-dependent and independent mechanisms.
