Kwa muda mrefu sana sasa tumeaminishwa kwamba picha tuliyokuwa tunaonyeshwa kwamba ni ya Corona virus,ni kweli ni ya Corona Virus.Ukweli ni ni kwamba si ya SARS-COV-2,ni utapeli,Corona virus haijawahi kuwa isolated. Ile ni picha ya kitu kinachoitwa Corona Virus ni Exosome.Exosome ni nini hasa.Exosomes ni sehemu ya kawaida kabisa ya miili yetu,na zina faida nyingi kwetu. Pitia taarifa ifuatayo upate ukweli wa tunachodanganywa kuwa ni virus wa Corona.Kweli nimeamini kwamba wajinga ndio waliwao,na katika hili tumeliwa kweli kweli.
Millions of tiny bubbles, released from cells and packaged with molecular mail, are racing through your bloodstream right now. And until recently, only a handful of researchers gave them any thought.
Stephen J. Gould is one of those scientists. For more than a decade, Gould has devoted significant time and resources to understanding the cellular couriers. Called
exosomes, these lipid vesicles shuttle proteins and genetic information between both neighboring and distant cells. “They are just a ubiquitous fact of our biology,” the Johns Hopkins University School of Medicine professor says.

Exosomes can deliver therapies into cells that would otherwise be hard to reach.
Now they’re positioned to become a widespread tool for drug delivery.
Scientists have known about exosomes for decades, but as recently as 2006, only 508, mostly obscure, papers referred to them, according to PubMed. Today, a search on the site brings more than 8,000 hits, including several high-profile publications from the past year.
Exosomes, a subgroup of extracellular vesicles (EVs), have been recognized as important mediators of long distance intercellular communication and are involved in a diverse range of biological processes. Because of their ideal native structure and characteristics, exosomes are promising nanocarriers for clinical use. Exosomes are engineered at the cellular level under natural conditions, but successful exosome modification requires further exploration.
The biocompatible characteristics of exosomes, with suitable modifications, can increase the stability and efficacy of imaging probes and therapeutics while enhancing cellular uptake.
