D225E and D225N H1N1 RBD Changes in Turkey

Recombinomics Commentary
January 5, 2010

The Refik Saydam National Public Health Agency has released 29 HA [hemagglutinin] sequences from Ankara, Turkey. Several were partial sequences, but 26 covered the receptor binding domain and 8 had D225E,… while one had D225N,… 

My comment:  D225 is the most common or wild-type receptor binding protein - the hemagglutinin (HA) protein – which enables the virus to bind to tissues in the respiratory tract of infected people. 

A change in the amino acid in position 225 of the receptor binding domain (RBD) is symbolized by using the letter representing the new amino acid, e.g. "G" for glycine in "D225G." The marker D225G signifies that a glycine (G) is present in the 225 position, replacing the amino acid usually in this position, aspartic acid, or D (hence the wild-type marker is "D225"). Glutamic acid, E, and asparagine, N, are two other amino acids that have been found in this position in non-wild-type swine flu viruses.

The change in the receptor binding protein from D to G alters the protein’s preference for binding to human tissues. Viruses with the D225G marker bind in the lung tissue, rather than binding in the upper respiratory tract (nasal area and throat), the more typical target. This appears to result in more severe disesase which may trigger a "cytokine storm" reaction in the lungs.  Whether substitution with "E" or "N" causes similar changes is not known. Theoretically, if the immune response is generated against the wild-type protein D225, viruses with D225G, D225E or D225N markers might avoid the immune system’s response. 

[Back to Dr. Niman] The outcomes of these patients were not given but media reports have described a rapid in increase in H1N1 fatalities in Turkey.  A large number of HA sequences with D225E has been published from Spain, and recently released GISAID sequences from Sweden and the UK also have D225E, including three fatal cases from Sweden. The prior reports of D225G and D225N associations with fatal cases has raised concerns that changes at position 225 could alter tissue tropism or aid in immune escape, leading to more severe and fatal cases.

Flu Watch Update – Ilene

When is a flu pandemic not a flu pandemic?

By Debora MacKenzie, consultant at New Scientist

H1N1 swine flu continues to roam the planet. In the US, cases are thought to be in the hundreds of thousands. In Japan, hundreds of teenagers have caught it, despite no obvious connections with Mexico or the US.

Yet in Europe, health authorities are not testing widely for it and are prescribing drugs as though they could still contain it. And in Geneva, health ministers have fought this week to keep the World Health Organization from following its own rules and calling this a pandemic.

So are we in a pandemic or not? And have we got the whole idea of a flu pandemic completely wrong?

No. There has been a phenomenal mismatch between quite sensible rules about how to declare a flu pandemic, and equally sensible rules about how to respond. The mismatch was wholly predictable, yet somehow no one saw this coming.

The WHO rules for declaring different degrees of flu pandemic threat are based on epidemiology (how the virus is spreading) for good reasons. This is because any new flu virus to which most of the world has little immunity, and which spreads well enough person-to-person to escape its continent of origin, is very likely to go global, and to cause more sickness and death than flu usually does. That is the definition of a flu pandemic

…As I write, the number of confirmed cases in Japan (and that’s just people sick enough to see a doctor and get tested) has jumped by 35 in the past 24 hours, to nearly 300, mostly due to that perennial vector of flu, the gregarious teenager. The main cluster started without any known links to the Americas.…

Billionaire Michael Bloomberg is used to getting his way. After serving two terms as New York City’s Mayor as a Republican, he used his own vast stash of cash to repeal term limits and give himself another four-year term, running as an Independent. Now he has promised to do the unprecedented: spend $1 billion of his own money to install himself as President of the United States, running on the Democratic ticket.

Bloomberg’s campaign increasingly resembles an octopus with money gushing out of its tentacles into anything and everything that will inject Mic...

Coronavirus: the blow to the Chinese economy could be felt for years

Investors are still being fairly complacent about the novel coronavirus. After the number of new daily cases suddenly shot up to more than 15,000 on February 12 following more than a week of decline, there were some jitters in the markets. With Chinese authorities saying the increase was due to a decision to broaden the definition for diagnosing people, there were falls in the region of 1% in European markets, and smaller retrenchments in Asia and North America.

Is The Technology Sector Setting Up For A Crash? Part I

One thing that continues to amaze our research team is the total scale and scope of the Capital Shift which is taking place across the globe.  For almost 5+ years, foreign investors have been piling into the US stock market chasing the stronger US dollar and continued advancement of US share prices. It is almost like there is no other place on the planet that will allow investors to pool capital into such a variety of strong assets while protecting against foreign capital risks.  Yet the one big question remains – when will a price reversion event hit the US stock
market?

So many researchers, even our team of researchers, believe we have found the keys to unloc...
