The cellular signaling network refers to the complex system formed by the interactions between various signaling molecules and receptors within and between cells. It consists of multiple signaling pathways that mediate intricate cellular interactions both internally and externally. The development of cancer is closely associated with the intricate signaling transduction network within cells, where multiple signaling pathways are interconnected and collectively regulate the biological phenotypes of tumor cells.

At present, less than 30% of researchers worldwide are women. Long-standing biases and gender stereotypes are discouraging girls and women away from science-related fields, and STEM research in particular. Science and gender equality are, however, essential to ensure sustainable development as highlighted by UNESCO. In order to change traditional mindsets, gender equality must be promoted, stereotypes defeated, and girls and women should be encouraged to pursue STEM careers. Therefore, Frontiers in Immunology is proud to offer this platform to promote the work of women scientists, across all fields of Cancer Immunity and Immunotherapy.
