Agranular leucocytes includes lymphocytes and monocytes. Lymphocytes (T cells‚ B cells and natural killer cells) mediate immune responses‚ including antigen-antibody reactions. B cells develop into plasma cells‚ which secrete antibodies. T cells attack invading viruses‚ cancer cells‚ and transplanted

According to the type of nerve fibers involved and the predominant nature of injury‚ GBS can be divided into acute inflammatory demyelinating polyneuropathy (AIDP)‚ acute motor axonal neuropathy (AMAN)‚ acute motorsensory axonal neuropathy (AMSAN)‚ Miller-Fisher syndrome (MFS) and some other relatively rare subtypes.

Most people with Hodgkin lymphoma have the classic type. With this type‚ there are large‚ abnormal lymphocytes (a type of white blood cell) in the lymph nodes called Reed-Sternberg cells. Hodgkin lymphoma can usually be cured. There are many different types of NHL that form from different types of white blood cells (B-cells‚ T-cells‚

genetic disease that affects humans at the earliest stage of life. As an immunodeficiency disorder‚ it affects the immune system of the human body. The syndrome impairs the function of T cells and causes an absence of B cells. Both of these cells are lymphocytes and a type of leukocyte or white blood cell. In turn‚ this cause patients to have a hard time fighting off various types of infections that include fungal‚ viral‚ and bacterial antigens.
