The immune system is the most diffuse cellular system in the body. Accordingly, long-range migration of cells and short-range communication by local chemical signaling and by cell-cell contacts are vital to the control of an immune response. Cellular homing and migration within lymphoid organs, antigen recognition, and cell signaling and activation are clearly vital during an immune response, b...

There is not sufficient evidence on its effects on human immune system thereby we investigated its modulatory effects on some cellular immune response parameters in breast cancer patients.
