A monokine is a type of cytokine[1] produced primarily by monocytes and macrophages.
Some monokines are: Monokines released from macrophages can attract neutrophils, via the process chemotaxis.
The secretion of monokine, prompted by interferon gamma, has activity for the receptors found within immune cells, such as T-cells, hindering their ability to function as regulators of the body.
Thus, promoting tumor progression in the cancer-state.
[4] In fact, its activity is important in other diseases, such as pulmonary tuberculosis, where researchers have identified monokine as a biomarker.
