For 10 points, name this process often performed by immune cells like neutrophils and macrophages, the ingestion of a foreign material by a cell.
Several of the genes activated during this process are controlled by p38, which is acted upon by the Myd88 adaptor protein.  In the liver, this process is primarily performed by Kupffer cells, and Lyn and Syk are responsible for activating the opsonin-dependent version of this process. It creates an internal (*) vesicle whose contents can be degraded by defensin-containing granules or reactive oxygen species, and neutrophils perform this process when encountering IgG-coated bacteria.
