COPD and cytosolic infections

Two types of COPD : emphysema and chronic bronchitis

Looking at COPD : there appears to be a type of COPD  that has high eosinophils due to infections/toxins in the cytosol and a type of COPD that involves 25 HC and viral infections.


COPD: emphysema and bacteria/mycobacteria infections of the cytosol

il-17 and il-22 COPD

The immune system is looking for a bacterial/mycobacteria infection in the cytosol. Note that il-22 is the vacuole pore. il-17A calls neutrophils by stimulating il-8.
