The Overblown Cytokine Storm and 225G from 1918

225G is not new and this "Cytokine Storm" phraseology is overblown.

The public perception of 225G and the media linkage to hemorrhagic pneumonia is new. 

These Hydra Effect viral backgrounds carrying 225G within ΣPF11 are, in fact, very dangerous strains for what they are doing now and, more importantly, for where they are going . . . no question exists about that risk tendency.  The only question is why hasn't the science community driven the clinical linkages to the forefront before this week?  Fatal outcomes have been documented on record since July in multiple cases from Brasil.

Obverse speculation is also dangerous, especially risky when speculating based on poorly defined terms.  Banter and rant occur with much vitriol and then everyone who needs the data stops listening.  Few conversations are more demoralising that the ones where you have no anchor point on the major terms.

A primary topic of concern is Cytokinic Dysregulation.  Reliance on inspecific phrases like "Cytokine Storm" in the media will only continue to misinform the public on a process that is far less understood than the lead investigators would like to admit.

All of which returns us to the basic categories:
  • What we do know?
  • What we don't know?
What we do know?

Now that 225G matched clinical data is available, however limited, a potential correlation is being drawn on lung tropism. The standing bench studies, including the Palese and JKT team collaboration in 2006, detailing variant tropism based on differential HA reception at α2-3 and α2-6-linked sialic acids evaluated correlative to aa225 lend evidence to the concept of deep lung involvement though the experiments were conducted by varying permutations of aa190 and aa225 on 1918 variants.  Whereas, we stand in 2009 with quite different genetics that require cross-validation prior to citation with applicability to PF11.

Tissue type targets are compelling studies and this particular superarray protocol may prove even more useful on PF11 than 1918 samples.  We note that though 1918 and PF11 now share 190D and 225G, that all 1918 public sequences show 206S206T continues to emerge and conserve regionally in PF11.  All 225G bearing strains after April show 206T, except the July CatNS1706 and the undated Vladivostok01.

Reproducing the glycan microarray procedure with the contemporary and ideal dataset including Brasil and Catalonia may bring a tigher focus onto today's issues.  We couldn't ask for a more balanced set of control factors with Catalonia offering sequences less than one week apart demonstrating both important pairings: 206S/225G and 206T/225G . . . a bench review made to order.

We also do know that a proper immune response, that is a timely and regulated innate immune response, is not occurring in certain of these patients. When the n +1 generations of the virus progeny begin to lyse the host cells, that failure of innate immune function to have responded early leads to an undetected and massive viral load due to the rapid replication trait of PF11. The cell detritus and the density of moving viral particles elicit a host-driven, limited “self-destruct” series of events because the multiple levels of early detection parameters have been bypassed leaving the core essentially defenseless.

What we don’t know?

Much of what we need to know today about Cytokinic Regulation is yet to be studied. 

The systems of feedback loops are extensive with individual effectors often having multiple functions, in some cases, opposing functions.  So please bear in mind that we are looking into an instantaneously self-modifying system that not only self-revises the systemic parameters, but recruits and removes players in the middle of the game and then encourages them to change sides without even changing jerseys.  And to top the difficulties, Heisenberg applies.  Tighten down the screws to look at one molecule and his best friend will no longer stand anywhere near him, though they were conversing with verve before we attempted to measure.

That disclaimer in place, you may still note important aspects of proper cell-to-cell signaling systems from the following discussion as you keep in mind that the presentation is highly compressed for educational purposes.

Though Cytokinic Dysregulation is occurring in most PF11 cases at some level of interchange, the 225G and 225E strains may potentially interfere at a more profound level with the early innate response by amplifying the PF11 conserved effect of the NS1 paired Glutamates at aa96 & 97 that constrains the IFN synthesis instantiation cycle by binding TRIM25, an early catalyst to RIG-I ubiquination.  Influenza bench researchers don’t know exactly where the failure is occurring or at which combination of cell-to-cell signalers in PF11 or the PF11 225G strains.  Until those identification studies are designed, undertaken and reproduced, discussion at this point is stark hypothesis based frequently on the speaker’s sheer lack of present research content mastery. Apparently, saying “I don’t know?” and then returning to the bench to design and gather a proper foundation of data is a skill rarely encouraged in our “Science for Hire” era.

Our team is unimpressed that the wider science community, with such broad analytical skills and exceptional equipment, relies on pseudo-explanation, this cloud of diversion, by invoking the “Cytokine Storm” phrase.  More than 20 well-characterised and 100 identified distinct molecular signal functions are at work in the early immune response, including cytokines, but not limited to that class of communicators.  Tagging a term for PR purposes is much simpler than tagging a molecule for tracking, but you received your instruments because you can think, not for your ability to improvise inventive talk.

Think.

Eighty billion dollars in research should arrive at a better answer with higher specificity and actionability than the blanket “Cytokine Storm” tome.  Data and procedure discover Facts.  Anything less is purely Public Relations.

Our team continues to hold an opinion that we first described in 2006 concerning Cytokinic Dysregulation and the NS1 protein of Influenza.  Succinctly, the viral ability to suspend innate immunity for up to two days post-infection, as characterised by Mount Sinai this year, prevents the early and required pro-inflammatory Cytokinic Response to viral detection.  That blunting, taken in conjunction with detailed studies around adaptive immunity, may result not only in failure to clear the virus from some patients in a timely fashion, but also in failure to produce a useful quantity and competence of memory T-cells and Ab.  The early failure to clear a rapidly replicating virus like H5N1 or PF11 results in a frank trauma to the immune system when the first generations of viral progeny lyse their host cells after being undetected and flood the tissues with virii and toxic cell detritus.  That disorderly surge of human and viral proteins en masse activates a late and cascading pro-inflammatory response that frequently fails to down-regulate properly.

This explanation is contrary to "pop" science reports that a normal and robust immune response over-generates cytokines and attacks self indiscriminately.  We hold that, by the time the virus has lysed thousands of cells and released millions of virii, that most adjacent tissue areas are "fair game" for immune response due to toxic cell detritus and viral travel.  That flooding of antigen and waste matter, widespread and instantaneous to the immune system, may further interact with some virally induced derangement of the alternative pathway of complement and generate the intensive up-regulation of signaling, pro-inflammation cascades and the resultant tissue damage described in the clinicals as DIC, DAH and ARDS.

Ergo, the findings of massive tissue damage on necropsy is the result of a failed early innate immune response, not a normal robust response.  A normal, properly up- and down-regulated robust innate response clears infection in more than 90% of various infections (viral, fungal and bacterial) and proceeds to generate Ab in short order via the adaptive arm of immunity.

When viral hosting cells properly detect intrusion, flag themselves for apoptosis (cell death) and are then assisted by cytotoxic T-cells, the injection of fragmentins via perforin "tubes" induces an endogenous apoptotic program literally cutting DNA into 200 base multimers (fragments) and eventually condensing chromatin.  That organised molecular result is far less inflammatory and far more useful for antigen identification than the disorderly outcome of a virally "exploded" cell.  Now you can see why proper genetic expression during each phase of this programmed cell death guarantees a lower pathology than the chaotic and toxic outcome of lytic host cell destruction resulting from viral NS1-induced, delayed genetic expression. 

A confluence of PF11 traits (failed early detection, multi-tropism and rapid replication) against the host-pathogen interface may force a limited "self-destruct" in the host upon eventual detection in an attempt to save the organism.  That limited "self-destruct" is not the desired outcome of a normal and robust immune response, but occurs due to a failure of the immune system to detect and respond early in the process.

Timing matters. 

Individual viral genetics and individual host immune genetic expression are primary effectors that must no longer be discounted under the clouds of some nebulous "Cytokine Storm" or Mysterious Mutation.

Cytokinic Dysregulation is wider than immunity. 

Johns Hopkins School of Public Health estimates that half of all Americans suffer from chronic illness.  150 million in one country.  Cytokinic Dysregulation is a very real situation occurring daily in the lives of a significant group of chronic illness sufferers as a component of asthma, chronic joint damage, digestion tract insult, diabetes, endocrine dysfunction, vascular inflammation of undisclosed cause, detoxification pathway insult (renal/hepatic), immune dysfunction, obesity and numerous sub-clinical, but accumulative pathologies.  Each of these suffering individuals is at an increased PF11 risk based on the types and levels of cell-to-cell signaling failures across their systems.

So let's stop talking about this overblown "Cytokine Storm" and begin candid discussions with specificity about causality.
