In December, the FDA approved the first two cell-based gene therapies for treating sickle cell disease: Casgevy and Lyfgenia. And, like any emerging medical technology, the initial use of the ...
(Reuters) -The U.S. Food and Drug Administration (FDA) on Friday approved two gene therapies for sickle cell disease, making one of them the first treatment in the United States based on the Nobel ...
Casgevy works by editing the DNA in a patient’s stem cells — which are responsible for making the body’s blood cells — so that they no longer produce sickle-shaped cells.
[173] [174] In December 2023, the US Food and Drug Administration (FDA) approved the first cell-based gene therapies for treating sickle cell disease, Casgevy and Lyfgenia. Casgevy is the first FDA approved gene therapy to use the CRISPR-Cas9 technology and works by modifying a patient's hematopoietic stem cells. [175]
Writing in 2018, in the Journal of Law and the Biosciences, Sherkow et al. argued for a narrower definition of gene therapy than the FDA's in light of new technology that would consist of any treatment that intentionally and permanently modified a cell's genome, with the definition of genome including episomes outside the nucleus but excluding ...
Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...

The quasispecies model is a description of the process of the Darwinian evolution of certain self-replicating entities within the framework of physical chemistry.A quasispecies is a large group or "cloud" of related genotypes that exist in an environment of high mutation rate (at stationary state [1]), where a large fraction of offspring are expected to contain one or more mutations relative ...
