Dendritic cells (DCs) are named after their branched projections called dendrites. These cells are the sentinels of the immune system and are always testing their surroundings in case they see any danger. DCs process antigens they pick up from their surrounding and present these to T cells. This video shows how dendritic cells …
T cells are named after the organ they develop in, the Thymus. Cytotoxic T cells (CTLs) are a special type of T cells with the ability to kill other cells. Usually they kill cells that have been infected with a virus. This way the virus can no longer use these cells for replicating inside of …
Macrophages are white blood cells. The word macrophage comes from the word macros “large” and phagein “eat”. Macrophages are big cells that eat.One of their main roles of these cells is to phagocytose (engulf and then digest) cellular debris and also pathogens such as bacteria. This process is known as PHAGOCYTOSIS. It is a complex mechanism …
Antibody producers B cells in the human body develop in the bone marrow and are therefore called B cells. These cells are responsible for producing antibodies. The antibodies produced by B cells circulate around our body and bind to specific viruses or bacteria to neutralize them and help get them killed by other cells of the …

This animation is a cartoon depicting a macrophage chasing bacteria to ultimately phagocytose them. Macrophages are white blood cells. One of their main roles is to engulf and then digest pathogens such as bacteria. This process is known as PHAGOCYTOSIS. It is a complex mechanism that requires for the macrophage to rearrange its inner cell …
Dendritic cells are named after their branched projections called dendrites. These cells are the sentinels of the immune system and are always testing their surroundings in case they see any danger. Dendritic cells present antigens to T cells. They use a molecule called histocompatibility complex (MHC) to display little bits and pieces of the antigens …
