Mast Cells are well known for their harmful role in IgE-mediated
Cells of the immune system, particularly certain types of white blood cells, primarily target cancer cells. The main types of immune cells involved in targeting cancer cells include: Cytotoxic T Cells (CD8+ T Cells): These cells directly attack and destroy cancer cells by recognizing specific antigens present on the surface of the cancer cells. Natural Killer (NK) Cells: NK cells are a type of lymphocyte that can recognize and kill abnormal cells, including cancer cells, without prior sensitization or the need for specific antigens. Macrophages: Macrophages are immune cells that engulf and digest foreign substances, including cancer cells, through a process called phagocytosis. They also play a role in presenting antigens to other immune cells to initiate an immune response against cancer. Dendritic Cells: Dendritic cells are antigen-presenting cells that capture antigens from cancer cells and present them to T cells, thereby activating an adaptive immune response against the cancer. Tumor-Infiltrating Lymphocytes (TILs): These are lymphocytes that have migrated into the tumor microenvironment and are involved in recognizing and attacking cancer cells. Cytokine-Induced Killer (CIK) Cells: CIK cells are a type of immune cell that has been activated and expanded outside the body and then reintroduced into the patient to target and kill cancer cells. These immune cells, along with other components of the immune system, form a complex network known as the immune response, which plays a crucial role in recognizing and eliminating cancer cells from the body.
White cells play important roles in the immune system.

Antigen is usually a 'Foreign' protein, usually a microorganism enered in body. It iduces two types of response 1) Cell mediated. 2) Humeral or antibody response. It starts getting produced by 'B' cell in bone marrow. It starts appearing after about 2 weeks of challenge. It give a pick response between 1 to 2 months. It can be inhanced by reapeated challenge during this period. Third challenge or vaccine given at 6 to 9 months, respectively, gives enhanced antibody response. These antibodies are very specific in nature that it will neutralise that perticular protein only. It make the protein inactive. There by protecting body from that perticular protein.
Yes. White blood cells are one of the most important operational cells of the immune system. There are several sub classes of white blood cells that play crucial functions in the immune system.
Interferons are hormonelike peprides that lymphocytes and fibrolasts produce in response to viruses or tumor cells.
Helper T cells are a type of white blood cell that play a crucial role in the immune response by coordinating and regulating the activities of other immune cells. They help activate B cells to produce antibodies and assist cytotoxic T cells in killing infected cells. Helper T cells are essential for a properly functioning immune system.

Cytokines, also known as immune factors, are protein produced naturally by the cells and organs of the human immune system. They act on other immune system cells modulating the body's response to disease and infection. Cytokines can also regulate the growth of new blood cells in the bone marrow.Cytokines play a crucial role in the immune system response to all kinds of disease. They interact with organs and cells, alone and in combination with each other. The diverse role that cytokines serve in the immune system make them an ideal target for intervening or bolstering immune responses. Using recombinant DNA technology cytokines can be created in a laboratory. They have many treatment applications including cancer, multiple sclerosis, anaemia, and rheumatoid arthritis.
IMPORTANCE OF B LYMPHOCYTES: 1.b lymphocytes play important role in humeral immune response. 2.they secretes antibodies. 3.they differentiate into memory and plasma cells.
HIV infects cells in the central nervous system and the immune system. HIV's main target cell is the T helper lymphocyte. These cells play a crucial role in the immune system, by coordinating the actions of other immune system cells. A large reduction in the number of T helper cells seriously weakens the immune system3
