Lymphokines are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte.^[1] They are protein mediators typically produced by T cells to direct the immune system response by signalling between its cells. Lymphokines have many roles, including the attraction of other immune cells, including macrophages and other lymphocytes, to an infected site and their subsequent activation to prepare them to mount an immune response. Circulating lymphocytes can detect a very small concentration of lymphokine and then move up the concentration gradient towards where the immune response is required. Lymphokines aid B cells to produce antibodies.

Important lymphokines secreted by the T helper cell include:^[2]

Interleukin 2
Interleukin 3
Interleukin 4
Interleukin 5
Interleukin 6
Granulocyte-macrophage colony-stimulating factor
Interferon-gamma

B7-homolog 4 (B7-H4), a recently identified homolog of B7.1/2 (CD80/86), has been described to exert co-stimulatory and immune regulatory functions. We investigated the expression and the functional activity of B7-H4 in lung cancer in vitro and in vivo. Although a lung cancer cell line constitutivel

Abnormal immunity and its related complications are the major causes of mortality and morbidity in diabetes patients. Macrophages, as one of the important innate cells, play pivotal roles in controlling immune homeostasis, immunity, and tolerance. The effects of hyperglycemia on the function of macr
