IgG2 27HC or inflammasome triggering phagocytosis: How does IgG2 work? Updated with exosomes and HC patterns

Hypotheses:
27HC binds cytosolic viruses and holds them outside of the cell membrane while inflammasomes create GSDM windows in the membrane for the antibodies to bind large cytosol infections.

Or HC could mark the exosomes based on what it's carrying. Cancer vs cytosol virus or mito/nuclear virus so the cd169 cells who pick up the exosomes know what they have.

Or are these nuclear/mito viruses? Herpes, flu, HIV, and HBV are all nuclear/mito viruses that would be taken up by pDendritic

Cancers are started by nuclear viruses but they are are growing out of control without viral participation rather they are open book growth. (the carcionogen inhibited the virus)

Does the 27HC hold the viral RNA outside of infected cells for dendritic cells?

Flu B and C infects the cytosol of cells and the 25HC secreted by macrophages would insert themselves in the membranes of cells in the region...and hold the foreign viral RNA outside of the cells?

But for type A which infects the mitochondria it would lower il-10?

How does the RNA viruses in the cytosol get seen by antibodies of the immune system if the MHC1 is for mitochondrial and nuclear infections?

when the inflammasomes are involved the cells get IgG2 phagocytosis by eosinophils?

The infected cells were surrounded by eosinophils
