Visualizing and Characterizing Semaphorin Endocytic Events Using Quantum Dot-Conjugated Proteins.

Ioana Carcea, Deanna L Benson,

Neurons can endocytose soluble semaphorins to either initiate or interrupt signaling at the cell membrane. Depending on the cell type and even on the specific subcellular domain, the endocytic process will differ in intensity, speed, and modality, and will subsequently facilitate diverse actions of semaphorin molecules. Therefore, in order to ... Read more >>
