BetaII-Spectrin Gaps and Patches Emerge from the Patterned Assembly of the Actin/Spectrin Membrane Skeleton in Human Motor Neuron Axons

The paper uses imaging to study the spatial distribution of betaII-spectrin in human motor neuron axons, revealing a gap-and-patch pattern in the actin/spectrin membrane skeleton.

Tau isoforms modulate the axon initial segment controlling axonal trafficking and neuronal excitability

This study shows that tau isoform balance regulates axon initial segment maturation, excitability, and transport, linking cytoskeletal organization to neuronal function.

Distinct nanoscale membrane organizations of mucins and trans-sialidases in Trypanosoma cruzi

This study reveals the nanoscale organization of mucins and trans-sialidases in T. cruzi, showing segregated clusters and a shared fibrillar network with distinct structural features.

Nanoscale organization of betaII-spectrin within segments of the membrane-associated periodic skeleton in mouse sciatic nerve axons

This study uses super-resolution microscopy to reveal the nanoscale organization of betaII-spectrin in mouse sciatic nerve axons, showing discrete clusters with specific spacing and density.

Direct single-molecule detection and super-resolution imaging with a low-cost portable smartphone-based microscope

This paper introduces a low-cost smartphone-based microscope capable of single-molecule detection and super-resolution imaging without signal amplification.

Dual spatio-temporal regulation of axon growth and microtubule dynamics by RhoA signaling pathways

This study shows RhoA signaling has both inhibitory and stimulatory effects on axon development depending on timing, location, and downstream effectors.
