Hypothesis: il-27 cytokine is secreted by B cells when there is a viral infection or cancer damage involving the cytosol of cells.

Is il-27 involved with DNA damage?

melanoma is a cancer caused by DNA damage (from sun exposure)

B cells major source of il-27

B cells produce IgG2a (class switch) after il-27

il-27 attracts myeloid dendritic cells to the lymph

previous hypothesis:
myeloid dendritic cells are involved with infections of the cytosol
plasmacytoid dendritic cells are involved with infection of the mitochondria/ nucleus

il-27 not il-35 suppresses gm-csf

GM-csf is involved with vacuole bacteria and TH17 triggering

GM-csf exposed Basophil's produce il-6 and trigger th17

GM-csf exposed mDendritic make il-23

As a cytosol infection TH1 is involved

il-27 is saying it is in the cytosol..what ever it is...not a bacteria hiding in the cytosol or in a virus in the nucleus or mitochondria.

Furthermore

il-27 suppressed il-5 and il-13 from TH2 cells which is used against parasites in the cytosol. Which means il-27 could be strictly a cytokine for viruses or for DNA from cancer in the cytosol?

When does the B cell decide to make il-27? Does the T follicular cell recognize it as DNA and signal back to the B cell?
