As this virus has not, by current reports, circulated in humans previously, it is unclear why the virus would evolve to have fewer T cell epitopes than predicted.
It is interesting, however, in light of the closeness of the company's relationship with Lyft before now, and rumors that circulated previously that GM may have suggested to Lyft it was interested in purchasing the smaller company, though Lyft has since denied that any formal acquisition talks took place.

By using the BLAST tool, it was observed that all Uberlandia's strain sequences showed high identity with sequences of influenza viruses that had circulated previously in other regions of the world [see Additional file 1].
Unlike seasonal influenza epidemics caused by viruses that mutate in small but important ways from year to year, a process known as antigenic drift, pandemic influenza is caused by a virus that is dramatically different from those that have circulated previously, which can occur through a phenomenon referred to as antigenic shift (2 ).
This corroborates the similarity between microglia and circulating macrophages previously shown by mRNA profiling.
Besides, we found a positive association between TIMP-1 and plasminogen activator inhibitor-1 circulating levels, previously found in myocardial infarction patients [ 5], probably suggesting a prothrombotic state.
