Respiratory syncytial virus (RSV), [a] also called human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a virus that causes infections of the respiratory tract. It is a negative-sense, single-stranded RNA virus. [2] Its name is derived from the large cells known as syncytia that form when infected cells fuse. [2] [3]
A syncytium (/ s ɪ n ˈ s ɪ ʃ i ə m /; pl.: syncytia; from Greek: σύν syn "together" and κύτος kytos "box, i.e. cell") or symplasm is a multinucleate cell that can result from multiple cell fusions of uninuclear cells (i.e., cells with a single nucleus), in contrast to a coenocyte, which can result from multiple nuclear divisions without accompanying cytokinesis. [1]
The syncytial theory rejects the theory of germ layers. During the development of the turbellaria ( Acoela ), three regions are formed without the formation of germ layers. From this, it was concluded that the germ layers are simultaneously formed during the cellularization process.
Oh, good! In addition to the planet literally being on fire, there is yet another respiratory virus running amok. While we're already dealing with surges of COVID-19, the flu and RSV (plus ...
A respiratory syncytial virus vaccine, or RSV vaccine, is a vaccine that protects against respiratory syncytial virus. [1] RSV affects an estimated 64 million people and causes 160,000 deaths worldwide each year. [2] The RSV vaccines Arexvy , [3] Abrysvo , [4] and Mresvia [5] are approved for medical use in the United States.
Cases of a respiratory virus that causes flu-like symptoms are surging in China, raising plenty of questions about what this could mean for the rest of the world.
