To prove this hypothesis, Lin and colleagues blocked cell endocytosis and examined Dpp morphogen movement. They found that inhibiting endocytosis disrupts the cell's ability to transduce Dpp signaling,...A clear view of mycobacterial infection

One of the host's first moves against the mycobacterium is the formation of a granuloma, an aggregate of cells, which consists of macrophages and other defensive immune cells.
