Langhans giant cells are large cells found in granulomatous conditions. They are formed by the fusion of epithelioid cells (macrophages), and contain nuclei arranged in a horseshoe-shaped pattern in the cell periphery. Their presence could indicate tuberculosis. A macrophage of a mouse stretching its arms to engulf two particles, possibly pathogens Macrophages (Greek: big eaters, makros = long, phagein = eat) are white blood cells, more specifically phagocytes, acting in the nonspecific defense as well as the specific defense system of vertebrate animals. ... The eukaryotic cell nucleus. ... Tuberculosis (abbreviated as TB for Tubercle Bacillus) is a common and deadly infectious disease caused by the mycobacterium Mycobacterium tuberculosis or Mycobacterium bovis. ...
They should not be confused with Langerhans cell. According to MeSH, Langhans giant cells are macrophages, but Langerhans cells are not. Langerhans cells are immature dendritic cells containing large granules called Birbeck granules. ... A mesh is similar to fabric or a web in that it has many connected or weaved pieces. ...
