Now, the dendritic cell is motile. And what that means is it can then move into the spleen or the lymph nodes of our immune system and it basically begins to interact with some type of T lymphocytes that once again has the CD four glycoprotein, the proper T cell receptor found on the membrane of that T lymphocyte. And when these two cells interact once again it elicits some type of defensive immune response. Now let's move on to our B lymphocytes. So recall that B lymphocytes are those immune cells of their humoral immunity, the antibody mediated immunity. So B lymphocytes can also engulf and take in these antigens that come from different types of pathogens found inside our tissues.
