bioRxiv
. 2024 Aug;
PMID: 39185223
Actin in neuronal processes is both stable and dynamic. The origin & functional roles of the different pools of actin is not well understood. We find that mutants that lack...

PMID: 38989012
Neurons exhibit complex branched axonal morphologies in both vertebrate and invertebrate systems, and show heterogeneity in the distribution of synaptic cargo across multiple synapses. It is possible that differences in...

. 2024 Jul;
35(9):ar115.
PMID: 38985513
The polarized nature of neurons depends on their microtubule dynamics and orientation determined by both microtubule-stabilizing and destabilizing factors. The role of destabilizing factors in developing and maintaining neuronal polarity...

Nadiminti S, Dixit S, Ratnakaran N, Deb A, Hegde S, Boyanapalli S, et al.
PLoS Genet
. 2024 May;
20(5):e1011253.
PMID: 38722918
Synaptic vesicle proteins (SVps) are transported by the motor UNC-104/KIF1A. We show that SVps travel in heterogeneous carriers in C. elegans neuronal processes, with some SVp carriers co-transporting lysosomal proteins...

Sabharwal V, Boyanapalli S, Shee A, Nonet M, Nandi A, Chaudhuri D, et al.
J Cell Sci
. 2024 Mar;

PMID: 38477340
Axonal transport in neurons is essential for cargo movement between the cell body and synapses. Caenorhabditis elegans UNC-104 and its homolog KIF1A are kinesin-3 motors that anterogradely transport precursors of...

PMID: 38467475
Asymmetric transport of cargo across axonal branches is a field of active research. Mechanisms contributing to preferential cargo transport along specific branches in vivo in wild type neurons are poorly...

PMID: 37194499
Stationary clusters of vesicles are a prominent feature of axonal transport, but little is known about their physiological and functional relevance to axonal transport. Here, we investigated the role of...

bioRxiv
. 2023 Mar;
PMID: 36865111
Synaptic vesicle proteins (SVps) are thought to travel in heterogeneous carriers dependent on the motor UNC-104/KIF1A. In neurons, we found that some SVps are transported along with lysosomal proteins by...

PMID: 36030563
Some organelles show a spatial gradient of maturation along the neuronal process where more mature organelles are found closer to the cell body. This gradient is set up by progressive...

Microtubules are fundamental elements of neuronal structure and function. They are dynamic structures formed from protofilament chains of α- and β-tubulin heterodimers. Acetylation of the lysine 40 (K40) residue of...
