In contrast, reagents that can block the abnormal function of pathogenic polyQ-containing Htt proteins, without compromising the required role of endogenous Htt in axonal transport would be especially promising for further development. WebApr 12, 2024 · 1 INTRODUCTION. Gigaxonin is a ubiquitously expressed protein encoded by the GAN gene located on human chromosome 16q24.1. 1, 2 The lack or loss of function of gigaxonin causes giant axonal neuropathy (GAN), an autosomal recessive disorder. The GAN gene has more than 50 distinct loss of function mutations that cause the disorder. 3 …

Neurons in the human central nervous system display highly complex axonal arbors that can branch thousands of times, reach hundreds of meters in total length, and contain hundreds of thousands of presynaptic sites distributed “en passant.”

WebJan 1, 1976 · Drugs that block axonal transport may thus modify neuronal protein synthesis in opposite directions either by interrupting retrograde transport of a trophic factor from the axon terminals or, by interfering with the normal supply of synaptic constituents to axon terminals, eliciting compensatory increases in synaptic input. WebOct 8, 2014 · In addition, microtubules also appeared intact and thus could potentially support axonal transport (Volpicelli-Daley et al., 2011). These representative images demonstrate that LN-like α-syn aggregates do not necessarily fill the axonal cytoplasm and would be unlikely to sterically hinder or block axonal transport.

WebCells are highly structured, and this structure is created and maintained using the cytoskeleton in conjunction with molecular motors. My research combines genetic and biochemical manipulations with biophysical techniques ( laser-tweezers, single-particle tracking and analysis, and computer modeling) to study cargo transport in vivo. WebFeb 20, 2004 · In observing axonal aggregates in Htt-Q128-expressing animals, it was noted that the diameter of Htt aggregates often exceeded that of normal larval axons. This suggested that large Htt aggregates might physically block axonal transport, as would be manifested by axonal swellings at the sites of blockage.
