A pass-through entity (PTE) includes partnerships, limited liability companies taxed as a partnership, S corporations, and trusts/estates. Income, losses, deductions, and credits typically flow through the entity and are taxed at the owner level, with the owner's share of income or loss included on his or her individual income tax return.
Once they are in the wound site, monocytes mature into macrophages. The spleen contains half the body's monocytes in reserve ready to be deployed to injured tissue. The macrophage's main role is to phagocytize bacteria and damaged tissue, and they also debride damaged tissue by releasing proteases.
Macrophages can be activated by cytokines such as interferon-gamma (IFN-gamma) and bacterial endotoxins, such as lipopolysaccharide (LPS). Activated macrophages undergo many changes which allow them to kill invading bacteria or infected cells.
