Subject: What's the difference of TH1 cells and TH2 cells effect?

Both cells are derived from CD4+ helper T cells. T cells that differentiate into TH1 principally secrete interferon gamma, 
lymphotoxin and IL-2. These will eventually, mainly stimulate the action of macrophage cells. On the other hand, TH2 cells 
are developed from T cells and mainly secreted IL-4 and IL10. Thier ultimate effect basically are to stimulate production of IG 
E and eventually stimulate mast cell degranulation. What i am curious about is what is the general major distinction of their 
effect on infection. Like, is it TH 1 cells more specific for intercellular bacteria infected cells and TH 2 specific for extracellular 
bacteria infected cells.
