Comparative Analysis of Ciliary Membranes and Ectosomes
Primary and motile cilia/flagella function as cellular antennae, receiving signals from the environment and subsequently activating signaling pathways that are critical for cellular homeostasis and differentiation [1-3]. Recent work with the green alga Chlamydomonas and the nematode C. elegans demonstrated that ectosomes can be released from the cilium and can mediate the intercellular communic...
متن کاملEctosomes
What are ectosomes? Ectosomes are vesicles of various size (0.1–1mm in diameter) that bud directly from the plasma membrane and are shed to the extracellular space. At variance with living cells, ectosomes have on their surface the phospholipid phosphatidylserine. These vesicles were long considered to be artefacts, and then they were confused with exosomes — the vesicles discharged upon exocyt...
متن کاملCiliary Secretion: Switching the Cellular Antenna to ‘Transmit’
Cilia are microtubule/membrane-based protrusions that mediate cell motility or transduce sensory information. New work in Chlamydomonas demonstrates that cilia can also act as secretory organelles by budding enzyme-containing vesicles from the flagellar membrane for post-mitotic hatching of daughters from the mother cell wall.
متن کاملTraining-based channel estimation for multiple-antenna broadband transmissions
This paper addresses the problem of training sequence design for multiple-antenna transmissions over quasi-static frequency-selective channels. To achieve the channel estimation minimum mean square error, the training sequences transmitted from the multiple antennas must have impulse-like auto correlation and zero cross correlation. We reduce the problem of designing multiple training sequences...
متن کاملThe Cilium Secretes Bioactive Ectosomes
The release of membrane vesicles from the surface of cells into their surrounding environment is now recognized as an important pathway for the delivery of proteins to extracellular sites of biological function. Membrane vesicles of this kind, termed exosomes and ectosomes, are the result of active processes and have been shown to carry a wide array of biological effector molecules that can pla...
