The name of the mutation, del 69-70, or 69-70 del, or other similar notations, refers to the deletion of amino acid at position 69 to 70. The mutation is found in the Alpha variant, and could lead to "spike gene target failure" and result in false negative result in PCR virus test. [270]
However, on July 9, Public Health England reported that the Delta variant in England had a case fatality rate (CFR) of 0.2%, while the Alpha variant's case fatality rate was 1.9%, although the report warns that "case fatality rates are not comparable across variants as they have peaked at different points in the pandemic, and so vary in ...
Studies have identified a range of animals—such as cats, ferrets, hamsters, non-human primates, minks, tree shrews, raccoon dogs, fruit bats, and rabbits—that are susceptible and permissive to SARS-CoV-2 infection. [66] [67] [68] Some institutions have advised that those infected with SARS‑CoV‑2 restrict their contact with animals. [69 ...

ZAP-70 was initially discovered in TCR-stimulated Jurkat cells, an immortal line of human T lymphocytes, in 1991. [6] Its molecular weight is 70 kDa, and it is a member of the protein-tyrosine kinase family and is a close homolog of SYK. SYK and ZAP70 share a common evolutionary origin and split from a common ancestor in the jawed vertebrates.
An animal model (short for animal disease model) is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the risk of harming a human. Although biological activity in an animal model does not ensure an effect in humans ...
[70] [71] In end-stage retinal diseases, the photoreceptors, as the primary light sensitive cells of the retina are irreversibly lost. By the means of prosthetic gene therapy light sensitive proteins are delivered into the remaining cells of the retina, to render them light sensitive and thereby enable them to signal visual information towards ...
As of June 2022, Omicron had about 50 mutations relative to the Wuhan-Hu-1 or B variant, [125] [126] which is more than any previous SARS-CoV-2 variant. Thirty-two of these pertained to the spike protein, which most vaccines target to neutralise the virus. [127] As of December 2021, many mutations were novel and not found in previous variants. [43]
