Can Global Genomic Surveillance Forecast the Next Pandemic?

PLOS: DNA Science

As soon as the initial RNA genome sequence of the pathogen that would be named SARS-CoV-2 was published, CDC and other organizations began developing diagnostic tests. • identifies parts of the virus to target to provoke an immune response from a vaccine. Work on vaccines ensued too. • Single-cell sequencing.

SARS-CoV-2 viral peptide fragments cause serious inflammatory response

Drug Target Review

We had built a machine learning classifier that has been trained to identify amino acid sequences that have the potential to mimic ‘host defense peptides’ from the human innate immune system. Such peptides play a critical role in the machinery for amplifying innate immune responses.

The Long Road to End Tuberculosis

Codon

If present before vaccination, memory immune cells primed to destroy the environmental relatives might cross-react with and neutralize the BCG strain before it has a chance to set up an immune response against itself and M. tuberculosis. A Peace Corps Volunteer administers the BCG vaccine to a six-year-old Korean boy.

Unlocking Undruggable Targets: Shifting Paradigms in Modern Drug Discovery

DrugBank

Another promising avenue is the use of technologies like RNA interference and gene editing, which allow scientists to turn off the production of certain proteins altogether. These methods could bypass the need to directly target these proteins with traditional drugs.

The Dangers of Mirrored Life

DNA and RNA molecules are also built from exclusively right-handed nucleic acids. Across the tree of life, organisms strictly require exactly one of the two chiral forms of their molecular building blocks — amino acids, nucleotides of RNA and DNA. 4 As far as we know, right-handed proteins never occur naturally.

CureVac provides update on Phase 2b/3 trial of first-generation COVID-19 vaccine candidate, CVnCoV

The Pharma Data

Phase 1 interim data reported in November 2020 showed that CVnCoV was generally well tolerated across all tested doses and induced strong antibody responses in addition to first indication of T cell activation. A pivotal Phase 2b/3, the HERALD study, with a 12µg dose of CVnCoV was initiated in December 2020. About CureVac.

Models of Life

But, regardless of which was first, they all operated with the same core data as their mechanism for understanding life: messenger RNA ( mRNA ). Partially as a marketing stunt and partially to save money, several companies opted to do no further testing before phase I trials after the approval of their internal models.
